What is demand?

It is desire from consumers for a particular good/service/commodity. The demand curve...

The demand curve shows the quantity demanded by consumers at each price of a good/service. Price and demand are inversely related i.e. as price increases the quantity demand decreases. This describes the demand curve is downward sloping.

There are two reasons one must know for why price and demand have an inverse relationship. 1. The real income effect As the price of a good/service increases it will eat a bigger chunk of the consumers income making them feel poorer so there are only a few people who are rich enough not to feel this impact. Also, the purchasing power has decreased (and all this means is that only a few people can afford expensive goods and services as they have the financial power.) 2. The substitution effectThis is that in our economy there is a lot of competition which keep prices low which is good for consumers. This means that there are many alternatives to the particular product you are looking for. For example if you wanted to buy window cleaning spray and saw it was £5.99 that may be relatively expensive for you so you might go into another shop and buy a different brand or similar cleaning product which will be cheaper therefore as the price of a good increases the demand decreases as consumers' will switch to alternatives. Important key term: Demand schedule : This is a table showing quantity demanded by consumers at each price level. This is table used to draw a demand curve.

What about s hifts?

Well a shift in the demand curve will only exist if a non-price determinant changes and the quantity demanded by consumers changes at every price.

In the demand curve above we can see that the demand for shares has decreased and this can be for several reasons. Why does the demand curve shift?

1. Tastes - social trends and fashion changes and this affects the demand for a good, For example at one point cassettes were very popular but as soon as CDs came the fashion changed to listening to CDs. The demand for cassette tapes decreased. 2. Income - If income increases then people have more purchasing power so the demand at every price level will increase. Vice versa if incomes suddenly decreased than the demand would decrease as people do not have a strong purchasing power. 3. Price of substitutes - substitutes as we mentioned before are alternatives. So if these decrease people are likely too buy more of them as their consumer surplus increases. This means that the good itself will incur a reduction in demand. For example if Pantene Pro-V hairspray became cheaper the demand for L'oreal hairspray would decrease because people would switch to the pantene Pro-V hairspray. 4.The price of complements - these are goods which complement each other i.e. go with each other. For example tea and milk. If the price of complement increases then the demand decreases. So for example if the price of milk rises then the demand for tea will decrease as people may switch tcheapero other cheaper alternative like black coffee or herbal tea, 5. Expectation of future price change - this doesn't tend to be as big as other factors. But in markets such as the housing industry or the share it has a big impact. If for example houses were supposed to increase prices in the future then the demand for houses will increase because people will wan to buy as they know they can sell it at a later date for a profit. 6. Population increase/migration- If there are more people then the demand for a product is likely to be be bigger. The two main ways in which a population can change are (i) population increase/ decrease through baby boom or increased availability of contraception and (ii) migration - this means people moving in and out of a country. 7. Distribution of income - This is by far the most interesting one. this suggest if the government increased taxes or benefits to the poor then demand for necessities will increase as that is what poor people will demand and the demand for luxuries will decrease as rich people loose some of their purchasing power for it, Quiz: 1. Demand for a normal product may cause the demand curve to shift outwards if... a) price increases b) price decreases c)the price of a substitute falls d) the price of a substitute rises. 2.A decrease in income should: a) Shift demand for an inferior product outwards b) Shift demand for an inferior product inwards

c) Shift supply for an inferior product inwards d) Shift supply for an inferior product outwards ANSWERS! 1) D- The demand curve will only shift outwards because of non-price factors such as the price of substitutes. If the price of substitutes increases then people are more likely to switch and buy this product. For example; orange juice and apple juice are close substitutes and if the price of apple juice goes people more people will be attracted to buy orange juice. 2) A - if income decreases then the quantity demand of an inferior will increase as they have an inverse relationship. Supply is not affected by the income elasticity of a product.

A complementary good is a material or product that can be used in association with another good, with this joint usage often helping to create additional demand for both of the goods involved. Typically, this dual use of the two goods provides additional utility and satisfaction for the consumer, making it advantageous to continue purchasing both goods over the long term. One of the benefits associated with the production of a complementary good is that demand will normally increase in conjunction with the demand for the associated material or product. The concept of a complementary good is different from that of a substitute good. In ter ms of substitutes, the focus is on replacing the use of one product with a different one that is able to fill the same needs and wants. In this scenario, there is no need for a companion product to increase the demand, just the desire to take away market share from the competitor and generate additional sales for the substitute product. By contrast, a complementary good is often designed to encourage greater consumption of that associated product, a strategy that ultimately means more sales and greater profits for both of the goods involved.

Manifesto of the New Economy! Free book on economics. adolgin.com Energy management solutions through utility system optimization Utility Optimization www.armstronginternational.com One of the easiest ways to understand what is meant by a complementary good is to think in terms of products that are often used together in order to create greater customer satisfaction. For example, jelly may be considered a complementary good for peanut butter, since the combination is widely popular in a number of cultures and settings. In like manner, potato salad may be considered complementary to the purchase of fried chicken, since the two are often

viewed as being ideal fare for a picnic. Gasoline may be considered a complementary good to the use of a car, since the gasoline makes it possible to enjoy a greater degree of utility from ownership of the vehicle. In many instances, the profitability of a complementary good is directly associated with the popularity of the associated good. As long as the demand is high for the associated good, there is a good chance that the complementary good will also enjoy brisk sales and produce revenue for the manufacturer. Should the demand for the associated good begin to wane, it is not uncommon for the sales of the complementary good to also suffer, unless the manufacturer can convince consumers that the product can also be used in conjunction with some other good that is currently enjoying widespread popularity.

Complementary Goods Complementary goods are those that are often used together, such as motor vehicles and gasoline or DVDs and DVD players.

Complementary Illustration When the price of one good declines (or increases) and the demand for a related good increases (or decreases), then the two goods are considered complementary. For example, if the price of computers increases and the demand for software declines, computers and software can be considered complementary.

Substitute Goods Substitutes are goods that are used in place of each other. Examples include CDs and digital music files, such as MP3s or ice cream and frozen yogurt.

Substitute Illustration If a price increase for one good leads to an increase in demand for a related good, then the two goods are considered substitutes. An increase in beef prices, for example, followed by higher demand for chicken or pork, indicates that chicken or pork represent substitutes for beef.

What is `a competitive market`? A market is where or when buyers or sellers meet to trade or exchange products.

This is the basic characteristics of all markets: - A physical place where, some mechanism whereby, buyers and sellers can meet or contact each other. - A willingness to trade or exchange or trade goods and services. A Sub-market is a recognised or distinguishable part of a market. It is also known as market segment.

Demand Demand is the quantity of a product that consumers are able and willing to purchase at various prices over a period of time. Some may confuse wants and demand and think it is the same thing. Wants is the same as Notional demand, which means the desire for a product. Demand is the same as Effective demand, which is the willingness and ability to buy a product. In addition to the definition of demand two other points have to be maid: - Ceteris paribus – which means other things remain the same. In other words, any changes in quantity demanded are due to the changes in the price of the product alone. - The quantity demanded must be time related (one day, week, month or year?).

Relationship between price and quantity demanded There is an inverse relationship between the price of a product and the quantity demanded. This means that, when lower the price, the more that will be demanded or the higher the price, the less that will be demanded.

The demand curve The demand curve shows the relationship between the quantity demanded and the price of a product. The data from which a demand curve is derived is taken id known as a demand schedule. Basically, this is a data set that shows how much of a product will be demanded over a range of prices. In the diagram below we see the market demand curve for June holidays to Ibiza.

Points to note from the diagram are that firstly, there is a normal inverse relationship between price and quantity demanded (price of holiday fall, quantity demanded increase). Secondly, the relationship is linear (straight demand curve). Thirdly, the relationship only applies for holidays that are taken in June. By using this we can for example find out how many holidays will be demanded at 200$(B/D). A shift like this is called a move ment along the demand curve.

Consumer surplus Cons umer surplus is the extra amount that a consumer is willing to pay for a product above the price that is actually paid. Below is an example of how consumer surplus can be shown under the demand curve.

The consumer surplus is the grey area in the chart above. In other words, the producer surplus is the area above the market price and below the demand curve. We also see that a change in price also causes the consumer surplus to change.

Calculation of total expenditure and total revenue The formula for calculating total expenditure and total revenue is: Total expenditure = price x quantity demanded

Other factors affecting demand There are three non-price factors recognised by economists as influencing the demand for most types of product. These are consumer income, the prices of other products and tastes and fashion. Cons umer income: More specifically consumer income is divided into real dis posable income and disposable income. Real disposable income is income after taxes on income have been deducted and state benefits. Disposable income is income after taxes on income have been deducted and state benefits have been added. It is most usual for demand for a product to increase if consumer income increases; such products are called normal goods. However, in some cases, the relationship between income and demand is inverse, which means that when income rises, demand falls. These products are called inferior goods. An example of this could be when income rises for a person he buys more expensive brands instead of the cheaper alternatives. The price of other products: A product usually has a substitute and/or a complement. A substitute is a competing good, which means that for example when the price of the product in question increases, which causes the demand to decrease, may cause the demand for the substitute to increase. A complement is a good for which there is joint demand. This means that for example, if the demand for the product increases it may cause the demand for the complement to increase as well. Complements can be for example steel and trains or bread and butter. Tastes and fashion: Peoples taste change often. For example advertisement may cause you to buy another product.

A change in demand due to a change in non-price factors

Change in demand is where a change in a non-price factor (such as consumer income, price of other products and tastes and fashion) leads to an increase or decrease in demand for a product. Demand curve shift to the right if: - consumer income increase - price of substitutes rise - price of complements fall - positive change in tastes and fashion Demand curve shift to the left if: - consumer income falls - price of substitutes rise - price of complements rise - negative change in tastes and fashion

Supply Supply is the quantity of a product that producers are willing and able to provide at different market prices over a period of time. Economists assume that the behaviour of suppliers is governed by the consistent need to maximise profit. Profit is the difference between the total revenue (sales revenue) of a producer and total cost.

Relationship between price and quantity supplied When prices increases the quantity supplied also increase (and vice versa), as producers always seek to maximise profits.

The supply curve The supply curve show the relationship between the quantity supplied and the price of a product. The data from which a supply curve is derived is taken from what is known as the supply schedule. This is a data set, which shows how much a product is likely to be supplied over a range of prices.

In the diagram below we see the market supply curve for holidays to Ibiza in June.

Points to note from this figure are that firstly, there is a positive relationship between price and quantity supplied (price increases, quantity increases). Secondly, the relationship is linear. It is possible to find out for example holidays will be supplied at a certain price.

Producer surplus Producer surplus is the difference between the price a producer is willing to accept and what is actually paid. Below we see how a producer surplus could look like.

The consumer surplus is in the grey area above. In other words, the consumer surplus is in the area between the market price and the demand curve.

Other factors affecting supply Cost of production: There are many things that affect the cost of production. The most obvious change is a change in the cost of factors of production. Size and nature of the industry: Competitive industries such as food production, very minor increases in cost can have a big impact on supply. In other markets, for example, where there is a strong brand or few producers, price competition is likely to be less important. Any cost increase can actually be passed on to consumers, because they will still most likely continue to buy the product. Government Policy: Governments can affect the supply of products in many ways. For example, many producers are subject to some form of indirect taxation such as Value added tax (VAT). Any increase in taxation will have to be passed on to consumers through increased prices; the increased prices will affect the willingness of producers to supply. Other factors:

Other factors that affect the production are for example change in agriculture and unexpected health scares.

A change in supply due to a change in non-price factors A change in supply occurs when a change in non-price influence leads to an increase or decrease in the willingness of a producer to supply a product. The supply curve may shift to the right if: - raw material costs fall - labour efficiency improves - there is reduction in the rate of indirect taxation - there is a positive technological advance - any other positive factor The supply curve may shift to the right if: - cost of raw material increase - labour cost increase - there is an increase in the rate of indirect taxation - there is a failed technological advance - any other negative factor

How prices are determined Price is the amount of money that is paid for a given amount of a particular good or service. The equilibrium price is where the demand and supply are equal. It is sometimes referred to as the clearing price. In practise, markets are unstable and not always in equilibrium. When this happens, the market is said to be in disequilibrium. In other words, demand and supply are not equal. When supply is greater demand, the price will fall because the producer will have unsold units left. This is called a surplus (an excess of supply over demand).

When demand is greater than supply, price will rise because there is not enough goods or services to meet the consumers demand. This is called a shortage (an excess of demand over supply).

The P represents the price equilibrium and the Q represents the quantity equilibrium. Demand and supply curve may shift, which also causes the equilibrium to change. For example a shift in the demand curve to the left (from D to D1) will cause both a decrease in the price of the product and the quantity supplied (new eq. is where S and D1 crosses). If the demand shifts to the right, the opposite would happen (increase in price and quantity supplied). If the supply curve shift to the left (from S to S1) will cause an increase in price and a decrease in quantity supplied (new eq. is where D and S1 crosses). If the supply curve shift to the right the opposite will happen (decrease in price and increase in quantity). The supply and demand curve may also shift simultaneous, which means the both shift the same direction at the same time. As a result of this the price will remain the same but, the quantity changes.

Elasticity Elasticity is the extent to which buyers and sellers respond to a change in the market conditions.

Price elasticity of demand Price elasticity of de mand (PED) is the responsiveness of the quantity demanded to a change in the price of the product. PED =

%change in quantity de manded %change in price Outcomes: PED is 0, which means demand is perfectly inelastic. In other words, the demand for a product will not respond to a change in price. PED is between 0 and 1, which means demand is inelastic. In other words, the demand for a product will not respond much to a change in price. PED is more than 1, which means demand is elastic. In other words, the demand for a product response quite a lot to a change in price.

Income elasticity of demand Income elasticity of de mand (YED) is the responsiveness of demand to a change in income YED = %change in quantity de manded % change in income Outcomes: YED is less than 1 means the demand is income inelastic. Income inelastic is goods for which a change in income produces a less than proportionate change in demand. YED is more than 1 means the demand is income elastic. Income elastic is goods for which a change in income produces a greater proportionate change in demand. YED is positive means that it is a normal good. YED is negative means that it is an inferior good.

Cross elasticity of demand Cross elasticity of demand (XED) is the responsiveness of demand for one product in relation to a change in the price of another product. XED = %change in quantity de manded

%change in price Outcomes: XED is positive means two goods are substitutes. XED is negative means two goods are complements. XED equals zero means there is no particular relationship.

Price elasticity of supply Price elasticity of supply (PES) is the responsiveness of the quantity supplied to a change in the price of the product. PES = %change in quantity supplied % change in price Outcomes: PES is between 0 and 1 means the supply is inelastic. PES is greater than 1 means the supply is elastic.

Allocate efficiency Efficiency is where the best use of resources is made for the benefit of consumers. Allocative efficiency is achieved in a market where consumer satisfaction is maximised. Scarce resources are used to produce those goods and services that consumers actually demand. To achieve this, the quantity supplied must be equal to the quantity that is demanded. In other words, the market must function at the equilibrium position. lasticity of demand measures the responsiveness of demand to a change in another factor, usually product price or consumer income. If there is a relatively small change in demand as the factor changes, demand is inelastic. If there is a relatively large change in demand as the factor changes then demand is elastic. If demand changes at the same rate as price there is unitary elasticity.

Demand basics explained Dec 28th Posted by admin in demand

761 comments Demand is the quantity of a good or service which consumers are willing and able to purchase at a particular price in a fixed period of time. The law of demand states that as price increases demand will decrease (demand varies inversely with price). This is because of the law of diminishing marginal utility which states each extra unit (the marginal unit) of a good or service consumed will give less satisfaction (utility) than the one before it. Therefore consumers will only be willing to pay less for it. It is for this reason that a normal demand curve slopes downwards from left to right. There are two other reasons why a normal demand curve slopes downwards from left to right. The income effect means that as the price of a good or service increases, consumers will have to spend a larger proportion of income on each unit and so not be able to afford the same quantity. The substitution effect means as the price of a good or service increases, rival products become more attractive. Demand curves can change in two ways. An increase in the price of a good is the ONLY thing that will cause a movement along a demand curve. This is known as an extension in demand if price decreases and a contraction on demand if price increases. Note again this is the only way the quantity demanded will move along a curve. If price changes we talk about a change in quantity demanded. There can also be a shift in demand. This is when the entire demand curve moves to the left or right in the diagram. If demand increases (instead of quantity demanded as above) then the entire curve will shift to the right. If demand decreases the curve will shift to the left. Remember: left is less and right is more. A shift in demand is a result in one of the factors affecting demand rather than price. Normal demand may shift because: Real incomes have increased so consumers can afford to buy more The price of a subsitiute or complementary good has changed making the original good more or less attractive The product may be advertised The population has become larger or smaller There is more credit available to consumers so they can borrow to buy what they couldn’t otherwise afford

Normal demand curves slope downward from left to right but some demand curves slope upwards from left to right. For example consumers may demand more of a luxury good at a higher price because they attach prestige or value to the high price. Demand for speculative goods may also increase as price increases as investors hope the good will keep on increasing in value.

Why are PPCs sometimes curves and sometimes straight lines? Dec 28th Posted by admin in production possibility curve 1,040 comments A PPC is always a curve if there are diminishing marginal returns. Diminishing marginal returns means that as firms switch raw materials from the first production process to a second, the extra output of the second process becomes successivley smaller. This is because different raw materials or factors of production are better suited to different production processes. For example, if you were to choose between growing wheat or rearing cattle on an area of land, some sections of the land may be more suitable for growing crops and provide lots of wheat compared to other sections. As the land owner switches more and more land to growing wheat, he must use less and less suitable sections of land that provide a smaller and smaller yield of wheat from the same sized area. Hence the PPC curves! If the PPC is a straight line, the land is equally suitable for both cattle and crops so each and every unit of land will yield the same quantity of crops and accomodate the same number of cattle.

What does ceteris paribus mean? Dec 28th Posted by admin in the basics 815 comments This is a latin phrase that literally means „all other things being equal‟. Economists use this phrase when they are dealing with a theory that involves several interconnected factors, each of which can vary. Since they are interconnected, if one factor is changed this will have an effect on at least some of the other factors. However an economist will only be concerned with changing one factor at a time to see what the effects of this are on everything else. This is so the economist can be absolutely sure it was the factor they themselves changed that caused the effect and not something else. Does this make sense? Maybe an example will help…. Imagine the market for any old product. Of course it will have an equilibrium price. This price will depend on lots and lots of interconnected factors. For example the level of demand, level of supply, price of raw materials and many more things. An economist might want to analyse the effect of a change in the price of raw materials for the firms in this market. The economist must only change this one factor and keep everything else constant. For example the economist must not also change the level of demand. This is so he or she can be sure it is the effect of a change in the price of raw materials that has caused the effect now shown. I hope this makes sense! Please remember ceteris paribus cannot exist in the real world but can make theoretical economic analysis a little bit easier.

Production possibility curve opportunity cost Dec 26th Posted by admin in production possibility curve 1,016 comments A PPC is also effective at illustrating opportunity cost. A choice must be made about the quantity of good X to produce and the quantity of good Y to produce.In this example if we want to make more of good Y, increasing production from 50 to 75 units, we must sacrifice 50 units of good X.

In general, you can use PPC diagrams to help you answer many exam questions, not just direct questions about the PPC itself, for example they can be used to describe the economy during recessions or booms.

Production possibility curve expansion Dec 26th Posted by admin in production possibility curve 1,008 comments This second PPC represents an economic growth. The possible production capability of the economy has actually expanded so even higher quantities of both goods can be produced. This may be as a result of new technology allowing production to become more efficient or an increase in resources, for example a boom in the size of the population. If the curve shifts to the right this is an expansion in capacity. If the curve shifts to the left this is a contraction in capacity.

FREE MARKET ECONOMY

This is specially for IGCSE grade 8. This will help you to understand FREE MARKET ECONOMY .............

Features All resources are privately owned by people and firms. Profit is the main motive of all businesses. There is no government interference in the business activities. Producers are free to produce what they want, how much they want and for whom they want to produce. Consumers are free to choose. Prices are decided by the Price mechanism i.e. the demand and supply of the good/service.

Advantages Free market responds quickly to the people’s wants: Thus, firms will produce what people want because it is more profitable whereas anything which is not demanded will be taken out of production. Wide Variety of goods and services: There will be wide variety of goods and services available in the market to suit everybody’s taste. Efficient use of resources encouraged: Profit being the sole motive, will drive the firms to produce goods and services at lower cost and more efficiently. This will lead to firms using latest technology to produce at lower costs.

Disadvantages Unemployment: Businesses in the market economy will only employ those factors of production which will be profitable and thus we may find a lot of unemployment as more machines and less labour will be used to cut cost. Certain goods and services may not be provided: There may be certain goods which might not be provided for by the Market economy. Those which people might want to use but don’t want to pay may not be available because the firms may not find it profitable to produce. For example, Public goods, such as, street lighting. Consumption of harmful goods may be encouraged: Free market economy might find it profitable to provide goods which are in demand and ignore the fact that they might be harmful for the society. Ignore Social cost: In the desire to maximise profits businesses might not consider the social effects of their actions.

Functions of stock exchange

Stock Exchange It is an organized market for the sale and purchase of securities such as shares, stocks and bonds. Stock exchanges are like markets where buyers and sellers of shares, stocks and bond meet. These are known as secondary market. Once shares are issued by companies, these can again be bought or sold through a Stock exchange.

Role of Stock exchanges Stock exchanges have multiple roles in the economy, this may include the following:

Raising capital for businesses The Stock Exchange provides companies with the facility to raise capital for expansion through selling shares to the investing public.

Mobilizing savings for investment When people draw their savings and invest in shares, it leads to a more rational allocation of resources because funds, which could have been consumed, or kept in idle deposits with banks, are mobilized and redirected to promote business activity with benefits for several economic sectors such as agriculture, commerce and industry, resulting in a stronger economic growth and higher productivity levels and firms.

Facilitating company growth Companies view acquisitions as an opportunity to expand product lines, increase distribution channels, hedge against volatility, increase its market share, or acquire other necessary business

assets. A takeover bid or a merger agreement through the stock market is one of

the simplest and most common ways for a company to grow by acquisition or fusion.

Redistribution of wealth Stocks exchanges do not exist to redistribute wealth. However, both casual and professional stock investors, through dividends and stock price increases that may result in capital ga ins, will share in the wealth of profitable businesses.

Corporate governance By having a wide and varied scope of owners, companies generally tend to improve on their management standards and efficiency in order to satisfy the demands of these shareholders and the more stringent rules for public corporations imposed by public stock exchanges and the government.

Creating investment opportunities for small investors As opposed to other businesses that require huge capital outlay, investing in shares is open to both the large and small stock investors because a person buys the number of shares they can afford. Therefore the Stock Exchange provides the opportunity for small investors to own shares of the same companies as large investors.

Government capital-raising for development projects Governments at various levels may decide to borrow money in order to finance infrastructure projects such as sewage and water treatment works or housing estates by selling another category of securities known as bonds. These bonds can be raised through the Stock Exchange whereby members of the public buy them, thus loaning money to the government.

Barometer of the economy At the stock exchange, share prices rise and fall depending, largely, on market forces. Share prices tend to rise or remain stable when companies and the economy in general show signs of stability and growth. An economic recession, depression, or financial crisis could eventually lead to a stock market crash. Therefore the movement of share prices and in general of the stock indexes can be an indicator of the general trend in the economy.

Question No: 41 ( Marks: 10 ) A. Differentiate between risk and uncertainty.

B. What would the risk neutral person, risk averse person and risk loving person do in the following cases? o If Odds Ratio > 1 o If Odds Ratio = 1 o If Odds Ratio < 1 C. You toss a coin, if head comes, you are given Rs. 200 and if tail comes, you have to pay Rs. 200. Will you play this game or not? Give your answer with brief explanation. (Marks: 3+3+4) Answers : A) http://www.allvupastpapers.blogspot.com/ Risk and Uncertainty : Risk is when an outcome may or may not occur but its probability is known while uncertainty is when an outcome may or may not occur but its probability is not known. Answers : B) 1) o o o 2) o o o 3) o o o

For risk neutral person If Odds Ratio > 1, then he will definitely buy If Odds Ratio = 1, then he will be indifferent If Odds Ratio < 1, then he might not buy as OR < 1 For risk averse person If Odds Ratio > 1, then in this case as well he might decide not to buy. If Odds Ratio = 1, then he will definitely not buy If Odds Ratio < 1, then he will definitely not buy For risk loving person If Odds Ratio > 1, then he will definitely buy If Odds Ratio = 1, then he will definitely buy If Odds Ratio < 1, then in this case as well he might decide to buy.

Answers : C) The tossing of a coin and the probability of a head appearing is 50% i.e. the odds of success are fair. So the option of OR < 1 and OR > 1 is not there. The only possibility is OR = 1 which means that the chances are not that bad. Now it depends on the fact that whether I am a risk averse, risk neutral or risk loving person. In case of fair odds both risk loving and risk neutral person might decide to play. So I will play this game as the amount of money involved is not that much and as far as my perception of it is concerned the marginal benefit of gaining 200 Rs is perceived by me as more than the marginal cost of losing the 200 Rs. So I would definitely play this game. Moreover the excitement of winning might overshadow my rational judgement and I would definitely decide to play by being carried away by excitement.

Elastic supply means relatively small changes in price causes relatively larger changes in quantity supplied. An elastic supply has a value greater than one (the negative value is ignored). Inelastic supply means relatively large changes in price causes relatively smaller changes in quantity supplied. An inelastic supply has a value of elasticity less than one (the negative value is ignored). The principle of equi marginal utility states that a person will derive a maximum level of Total Utility from consuming a particular bundle of goods when the utility derived from the last dollar spent on each good is the same OR the ratio of marginal utility to price of all the commodities should be equal to each other. MUa = MUb = MUc = ……………. Pa Pb PC Optimal point of consumption is that point where consumer surplus becomes zero. Consumer surplus is the difference between the price that consumer wants to pay and the price that he actually pays i.e. CS= Marginal Utility - Price. If marginal utility is greater than price, consumption will increase causing Marginal Utility to fall until it equals price, and vice versa. Rational choice is the optimal choice. Consumers can decide about the rational decision by using cost and benefit analysis. Rational choice is a choice where individuals try to make the most efficient decisions possible in an environment of scarce resources. As people want to maximize their utility with limited resources, this is a rational choice for consumers. Supply of food varies from time to time and according to the demand. Daily market supply of food like vegetables and fruits is fixed because these are perishable goods and go bad at the day end. However, foods like wheat and rice etc can be stored for some time period so its supply is not fixed and may vary according to the market demand.

In price floor, the government sets the minimum price to support a desired commodity or service in a society. At price floor, buyers are in equilibrium, but sellers are not. Sellers would like to sell more quantity, but buyers are not willing to buy all that quantity. To prevent the adjustment process from causing price to fall, government may buy the surplus. In price ceiling, the government sets the maximum price limit to ensure that prices don’t rise above that limit. Due to imposition of this limit, buyers want to buy more but sellers do not like the ceiling price so they don’t provide the required supply in the market. Because buyers cannot buy as much as they would like at the legal price, buyers will be out of equilibrium.Equilibrium can take place if market forces of demand and supply works and push the price upward but it does not work due to government intervention.

When there is increase in income, demand for inferior goods will decrease and demand curve will shift leftward. When there is decrease in price of substitute, demand will decrease and demand curve will shift leftward. When there is increase in income, demand for inferior goods will decrease and demand curve will shift leftward. When there is decrease in price of substitute, demand will decrease and demand curve will shift leftward.

DIAMOND-WATER PARADOX is in the context of marginal utility. Water and diamond are very different in value. Water is extremely used thing while diamonds are not much used. The price of diamond is very high while the price of water is very low. Since water is used widely so it’s marginal utility is very low. And diamonds are used very rarely so its marginal utility is very high. On supply side, water is abundant so has low value and diamond is scarce so has very high value.

Water is a necessity, human beings cannot even survive without water, whereas diamonds are luxurious good not necessity. Yet water had a very small price, and diamonds have very large price. For most people, water is sufficiently abundant whereas diamonds are in much more restricted supply that’s why water is cheap and diamonds are expensive. Risk Hedging means technique to avoid the risk. Example: Insurance companies operate under the principle of law of large numbers. An insurance company collects the premium from the people. They also diversify the risk. In the presence of asymmetric information, an insurance company has to contend with the problems of adverse selection (people who want to buy insurance are also the most risky customers; an ex-ante problem) and moral hazard (once a person is insured his behavior might become more rash; an expost problem). Ex-ante concept It is a neo-Latin word which means "before the event. Ex-post concept It is a Latin word which means "after the fact". There are two sides: demand side and supply side. According to supply side, the value of a good is determined by the labor content that is used to produce the good. According to demand side, the value of a good is determined by its marginal utility. Normal goods: If the price of good falls, the consumer’s purchasing power increases, income effect reinforces the substitution effect.

Giffen goods: If the price of good falls, the consumer’s purchasing power increases. But if the income effect for an inferior good is sufficiently strong, the consumer will buy less of the good when it becomes less expensive. There are no hard and fast examples of normal goods, inferior goods and Giffen goods. It depends on the consumer’s taste and preferences. One thing might be normal for one person but inferior for another person. For example, wine may be normal for non Muslims but inferior for Muslims. Some people prefer mutton so it is a normal good for them or might be they consider chicken as inferior good. So it all depends on consumer’s tastes. Giffen good is also a category of inferior good. The Income Consumption Curve (ICC) The income consumption curve (ICC) can be used to derive the Engel Curve, which shows the relationship between income and quantity demanded. Price Consumption Curve (PCC) The price consumption curve (PCC) traces out the optimal choice of consumption at different prices. The PCC can be used to derive the demand curve, which shows the relationship between price & quantity demanded. MPP = APP , APP does not change MPP > APP , APP upward MPP < APP , APP down This is the relationship between Average Physical Product and Marginal Physical Product. If you see the graph of Average Physical Product and Marginal Physical Product then you will find that: • If the marginal physical product equals the average physical product, the average physical product will not change. • If the marginal physical product is above the average physical product, the average physical product will rise.

•

If the marginal physical product is below the average physical product, the average physical product will fall………(end) Isocost or Budget Line The concept of isocost is similar to the budget line developed in indifference curve analysis. It is a line, which captures all the different combinations of inputs that the firm can afford to hire. Isoquant is the combination of inputs that provide the same level of output. The slope of an isoquant is called marginal rate of technical substitution (MRTS). MRTS is the amount of one factor, e.g. capital, that can be replaced by a one unit increase in the other factor e.g. labor, if output is to be held constant.

Marginal cost is the change in total cost resulting from a change in the quantity of output produced by a firm. Economies of scale arise when firms become bigger and bigger then their costs per unit of output fall. This could be because of larger more efficient plants, financial economies, more efficient specialized labour, bulk discounts on purchases etc. Diseconomies of scale are the forces that cause larger firms to produce goods and services at increased per-unit costs. If output increases by that same proportional change then there are constant returns to scale. If output increases by less than that proportional change, there are decreasing returns to scale. If output increases by more than that proportion, there are increasing returns to scale. Average total cost (ATC) is total cost per unit of output, it can be found by dividing total cost (TC) by the quantity of output (Q).

ATC = TC/Q Average variable cost (AVC) AVC is an economics term to describe the total cost a firm can vary (labor, etc.) divided by the total units of output. AVC = TVC/Q Price taker: A firm that does not have the ability to influence market price is a price-taker. In perfect competition, the firm is price taker. There are large number of buyers and sellers and firm can not influence on the market price. Price is set by the forces of demand and supply. Price maker: A firm that influences the market price by how much it produces can be called a price-maker orprice-setter. In Monopoly, firm is price maker. A monopoly or a firm within monopolistic competition that has the power to influence the price it charges as the good it produces does not have perfect substitutes. A monopoly is a price maker as it holds a large amount of power over the price it charges. Total Revenue & Total Cost approach According to this approach, profit is maximized at that point where the difference between total revenue & total cost is maximum. Marginal Revenue & Marginal Cost APPROACH According to this approach, profit is maximized at the point where MC=MR. If there is decrease in demand, there will be leftward / downward shift in demand curve. If there is increase in demand, there will be rightward / upward / outward shift in demand curve.

For convenience, just remember that rightward shift for increase in demand and supply and leftward shift for decrease in demand and supply. Profit Maximization: Firms are interested in profit maximization. Profit is the difference between total revenue & total cost. Higher the difference, higher is the level of profit. There are two approaches of profit maximization. One is Total Revenue and Total Cost approach and the other is Marginal Revenue and Marginal Cost approach. Production Possibility Frontier (PPF): A production possibility frontier (PPF) is a graph or curve that shows the maximum level of output that can efficiently be produced with limited productive resources. The law of demand states that if the price of a certain commodity rises, its quantity demanded will go down, and viceversa. The condition for consumer's equilibrium is expressed as …..Consumer's equilibrium occurs at the point where budget line is tangent to the indifference curve. Law of Diminishing Marginal Utility This law states that as more of a good is consumed, eventually each additional unit of the good provides less additional utility and marginal utility derived from the consumption of good decreases. Substitution effect of a price change is negative in case of normal goods. If price of a good increases then consumers moves towards its substitutes and consume those substitutes goods and will reduce the quantity of that goods whose price rose. So substitution effect is also negative. Income effect / real Income effect of a price change is negative in case of normal goods. If price of any good increases, real

income of consumer falls and he will consume less of that good. Since as price increases, real income decreases, purchasing power of consumers decreases so income effect of a price change is negative for normal goods. The term is Budget deficit. It is a situation government expenditures are greater than the revenues.

Law of Diminishing Marginal Utility This law states that as more of a good is consumed, eventually each additional unit of the good provides less additional utility and marginal utility derived from the consumption of good decreases. The law of diminishing marginal utility helps explains the negative slope of the demand curve and the law of demand. Marginal utility curve is negatively sloped. For example the initial cup of tea in the morning meets a large need and provides a large amount of satisfaction (utility). But as we consume another cup of tea, the satisfaction derived from the 2nd cup will be less than the 1stcup and so on. For two goods x and y the concave shape of PPF shows the increasing opportunity cost. 1. What effect is working when the price of a good falls and consumers tend to buy it instead of other goods? A. the substitution effect. B. the ceteris paribus effect. C. the total price effect. D. the income effect. 2:- Suppose the demand for good Z goes up when the price of good Y goes down. We can say that goods Z and Y are A. Perfect substitutes. B. Unrelated goods. C. Complements. D. Substitutes.

3:-If the demand for coffee decreases as income decreases, coffee is A. a normal good. B. a complementary good. C. An inferior good. D. a substitute good. 4:-When the decrease in the price of one good causes the demand for another good to decrease, the goods are A. Complements. B. Normal. C. Inferior. D. Substitutes. 5:- The price of apples falls by 5% and quantity demanded increases by 6%. Demand for apples is: A. Inelastic. B. Perfectly inelastic. C. Elastic. D. Perfectly elastic. 6:- The price of bread increases by 22% and the quantity of bread demanded falls by 25%. This indicates that demand for bread is A. Elastic. B. Inelastic. C. unitarily elastic D. perfectly elastic Question:what are sources of inefficiency in monopolistic competition? what is the effect of the fact that price exceeds marginal cost, Excess Capacity and Product Diversity on this efficiency? Answer: There are two sources of inefficiency in monopolistic competition: 1. At its optimum output, monopolistic competitive firm charges a price that exceeds marginal costs. The monopolistic competitive firm maximizes profits where Marginal Revenue = Marginal Cost. Since the monopolistic competitive firm’s demand curve is

downward sloping, this means that the firm is charging a price that exceeds marginal costs. 2. Monopolistic competitive firm operate with excess capacity. It means that the firm's profit maximizing output is less than the output associated with minimum average cost. Due to the fact that price exceeds marginal cost, there will be excess capacity. Price elasticity of demand is:Ratio of the percentage change in quantity demanded to the percentage change in price. Risk is when an outcome may or may not occur but its probability is known while Uncertainty is when an outcome may or may not occur but its probability is not known. ( 'ceteris paribus' meaning 'all else equal ) Opportunity cost: what we forgo, or give up, when we make a choice or a decision Question:-If the income elasticity of demand is 1/2, the good An inferior good or luxury good? Answer:-If the sign of income elasticity of demand is positive, the good is normal and if sign is negative, the good is inferior. Price floor results in excess supply or surplus of the product. If cross price elasticity is positive then the goods are considered as substitutes. Quantity demand will decrease as price increase. Demand curve will remains constant. Will Costs determine Firm's behavior ?? yes The term ex-ante means "before the event” e.g. in the financial world, the ex-ante return is the expected return of an investment portfolio. Ex-post means “after the fact” An explicit collusion is a formal, usually secret, collusion agreement among competing firms in an industry designed to control the market, raise the market price, and otherwise act like a monopoly. Explicit collusion is also known as overt

collusion. The distinguishing feature of explicit collusion is a formal agreement whereas no formal explicit agreement is involved in tacit collusion. Explicit collusion usually occurs in oligopolistic firms whereas tacit collusion is best understood in the context of a duopoly and the concept of Game Theory (namely, Nash Equilibrium). Similarities of oligopoly with other market structures: Oligopoly is similar to monopoly in the sense that there are a small number of firms (about 2-20) in the market and as such barriers to entry exist. It is similar to perfect competition in the sense that firms compete with each other which may result in prices very similar to those that would obtain under perfect competition. It is similar to monopolistic competition since there is a possibility of having differentiated products. Difference of oligopoly with other market structures: It is different with other market structures because there are few participants in this type of market, each Oligopolist is aware of the actions of the others. The decisions of one firm influence the other firms. This causes Oligopolistic markets and industries to be at the highest risk for collusion. It is not possible to identify any single equilibrium in oligopoly. Reason for that is the firms are interdependent. At any point on the indifference curve, the slope is equal to the marginal rate of substitution. if the income elasticity of demand is 1/2, the good is ? Normal good.

Price discrimination is the practice of charging different prices from different people for the same product. QUESTION:does an income consumption curve another name for income demand curve? ANS:Yes.

Income consumption curve is a curve that shows the relationship between income and demand. Normally as income rises, so demand rises also, but it can happen, as in the case of low value goods, that

when income rises demand falls as purchasers switch to higher-priced products.

Preference, Transitivity, Completeness and Convexity all are the properties of indifference curve. QUESTION:when the firm doesnt produce any output , is total cost zero? ANS: Total cost = Fixed cost + Variable cost Total cost will not be zero in case of no output produced, because fixed cost always exist whether output produced or not. Variable cost will be zero if output is zero. QUES: for a shoe manufacturer which cost is fixed and which is variable? cost of leather fee paid to advertising agency wear and tear on machinery? ANS: Cost of leather = Variable cost Fee paid to advertising agency = Variable cost Wear and tear on machinery = Depreciation cateris paribus means other things being remaining the same. A rational person will always select on the basis of marginal benefit is greater than marginal cost. Monopolists typically produce fewer goods and sell them at a higher price than under perfect competition, resulting in abnormal and sustained profit. change in total revenue divided by one unit change in output is called marginal revenue. The indifference curves are convex to the origin. This is due to the concept of the diminishing marginal rate of substitution between the two goods. If we consider indifference map, the higher indifference curve shows higher level of utility or satisfaction.

Negatively correlated means negative relationship. Uncorrelated means no relationship. A duopoly refers to a market condition in which two companies have control over the market while producing similar product. Duopoly is similar to monopolies in which only one company controls the market and oligopolies in which more than two companies are allowed to trade in the market. Relationship between APP and MPP •

If the marginal physical product is above the average physical product, the average physical product will rise.

•

If the marginal physical product is below the average physical product, the average physical product will fall. The slope is defined as: Rise / Run. Rise = Vertical distance between any two points on the line. Run = Horizontal distance between any two points on the line. Curve is the graphical representation of tables / schedules. If demand schedule is represented graphically, it is known as demand curve. The slope of demand curve is negative or downward. Oligopoly In this market structure, there are a small number of firms (about 2-20) in the market and there are also barriers to entry. A monopolist can make super normal, profits even in long run because there is no easy entry fo other firms as in the case of perfect competition therefore a monopolist can maintain her high price even in the long run.

Monopoly is the market structure where there is single seller. A monopolist has the ability to influence the market price. He is a price maker. Super normal profit:-Profit = Revenue – cost. Super normal profit is the profit where the positive difference between revenue and cost is maximum. Firm earns super normal profits in short run where revenue is greater than the cost, in long run it earns normal profit where revenue is equal to cost. Super normal profit is only possible in the short run not in the long run. An industry is earning super normal profit in the short run. Due to the attraction of this super normal profit, other new firms enter in the market. These new firms also produce products; supply of the product increases in the market, so the price goes down, profit squeezes and profit share is divided among all the firms so profit share of each firm reduces, so each firm earns normal profit in the long run. Ques: if the price of houses and the number of houses purchased both rise over the course of the year then what will be effect on demand demand curve, supply and house construction costs? Ans: It means that demand of houses has increased. People want to purchase houses irrespective of the increase in prices. Qu. if there are only two goods A and B,if more of good A is always preferred to less, and if less of good B is always preferred to more, then what happens to Indifference curves of both? Ans: Indifference curve will be downward sloping and convex to the origin. Elastic demand means relatively small changes in price causes relatively larger changes in quantity demanded. An elastic demand has a value greater than one (the negative value is ignored). Inelastic demand means relatively large changes in price causes relatively smaller changes in quantity demanded. An

inelastic demand has a value of elasticity less than one (the negative value is ignored). Question: A person with a diminishing marginal utility of income what is he said? Ans: The degree of risk aversion increases as your income level falls, due to diminishing marginal utility of income. Income effect of a price change is negative in case of normal goods. If price of any good increases, real income of consumer falls and he will consume less of that good. Since as price increases, real income decreases, purchasing power of consumers decreases so income effect of a price change is negati ve for normal goods. In elasticity, minus sign is ignored. We just see the value which is greater than 1 is elastic and which is less than 1 is inelastic. If elasticity is 3 which is greater than 1, it is elastic. If elasticity is 0.3 which is less than 1, it is said to be inelastic. Question No: 35 ( Marks: 3 ) Why the monopolists produce lower quantities at higher prices compared to perfectly competitive firms?

5) There is opening among the firms regarding their production process. 6) Government’s strictness in implementing antitrust law.

Question No: 37 ( Marks: 5 ) Differentiate between external economies of scale and external diseconomies of scale with the help of examples. Ans: External economies: These are the benefits which are accured to any firm in the presence of other firms. For example setting of credit information bureaus by bank , advertising by industry such as rival industry. Discovery of new techniques. This type of economy occurs when an industry is heavily concentrated in a particular area. Economies is available to all firms for example construction of roads External diseconomies of scale : These are the forces which causes the large firms to produce goods and services at increased per unit costs. This type of scale occurs when an industry grows larger and shortage of skilled laor taking place and shortage of raw materials are the types of external diseconomies. When a firm become large then supervision of workers become difficult and problem is created for management is taking place which cause adverse effect on efficiency. Risk loving is the person who wants to take the risk. Risk averse is a person who avoids taking the risk. Risk neutral is a person that is indifferent about taking the risk or not taking the risk.

Question:- What would the risk neutral person, risk averse person and risk loving person do in the following cases? o If Odds Ratio > 1 o If Odds Ratio = 1 o If Odds Ratio < 1 Answer:1) For risk neutral person o o o 2) o not o o 3)

If Odds Ratio > 1, then he will definitely buy If Odds Ratio = 1, then he will be indifferent If Odds Ratio < 1, then he might not buy as OR < 1 For risk averse person If Odds Ratio > 1, then in this case as well he might decide to buy. If Odds Ratio = 1, then he will definitely not buy If Odds Ratio < 1, then he will definitely not buy For risk loving person

o If Odds Ratio > 1, then he will definitely buy o If Odds Ratio = 1, then he will definitely buy If Odds Ratio < 1, then in this case as well he might decide to buy. Question :C. You toss a coin, if head comes, you are given Rs. 200 and if tail comes, you have to pay Rs. 200. Will you play this game or not? Give your answer with brief explanation Answer:The tossing of a coin and the probability of a head appearing is 50% i.e. the odds of success are fair. So the option of OR < 1 and OR > 1 is not there. The only possibility is OR = 1 which means that the chances are not that bad. Now it depends on the fact that whether I am a risk averse, risk neutral or risk loving person. In case of fair odds both risk loving and risk neutral person might decide to play. So I will play this game as the amount of money involved is not that much and as far as my perception of it is concerned the marginal benefit of gaining 200

Rs is perceived by me as more than the marginal cost of losing the 200 Rs. So I would definitely play this game. Moreover the excitement of winning might overshadow my rational judgement and I would definitely decide to play by being carried away by excitement. CHAPTER 1 1.
