Part A: IntroductionIn this opening part of the book you will get a glimpse of what the subject of economicsis all about. One thing to be stressed right from the outset: economics is not just a set offacts or theories to be memorised. Studying economics gives you a way of thinkingabout the world. It helps you to make sense of the decisions people are making all thetime: decisions we make about what to buy or what job to do; decisions our governmentmakes about how much to tax us or what to spend read more..

Many people think that economics is about money. Well, tosome extent this is true. Economics has a lot to do withmoney: with how much money people are paid; how muchthey spend; what it costs to buy various items; how muchmoney ﬁrms earn; how much money there is in total in theeconomy. But despite the large number of areas in whichour lives are concerned with money, economics is morethan just the study of money.It is concerned with the following:• The production of goods and services: how read more..
1.1 WHAT DO ECONOMISTS STUDY?5economists do not claim that we all face an equal problemof scarcity. In fact this is one of the major issues economistsstudy: how resources are distributed, whether between dif-ferent individuals, different regions of a country or differentcountries of the world.But given that people, both rich and poor, want morethan they can have, this makes them behave in certain ways.Economics studies that behaviour. It studies people atwork, producing the goods that people read more..
61 INTRODUCING ECONOMICSMicroeconomics is concerned with the individual partsof the economy. It is concerned with the demand and supply of particular goods and services and resources: cars,butter, clothes and haircuts; electricians, secretaries, blastfurnaces, computers and oil.?Which of the following are macroeconomic issues,which are microeconomic ones and which could beeither depending on the context?(a) Inﬂation.(b) Low wages in certain service industries.(c) The rate of exchange between read more..
1.1 WHAT DO ECONOMISTS STUDY?7much will pensioners receive? How much of the nation’sincome will go to shareholders or landowners?All societies have to make these choices, whether they be made by individuals, groups or the government. Thesechoices can be seen as microeconomic choices, since theyare concerned not with the total amount of national out-put, but with the individual goods and services that make itup: what they are, how they are made, and who gets theincomes to buy them.Choice and read more..
81 INTRODUCING ECONOMICSthroughout the book. Once you have grasped these con-cepts and seen their signiﬁcance, they will affect the waythat you understand and analyse economic problems. Theywill help you to ‘think like an economist’.Rational choicesEconomists often refer to rational choices. This simply meansthe weighing-up of the costs and beneﬁts of any activity,whether it be ﬁrms choosing what and how much to Scarcity, as we have seen, is at the heart of economics.We face scarcity read more..

Perhaps you will decide to set it for 7.30 or even 8.00.That will give you a longer night’s sleep, but much more ofa rush in the morning to get ready.So how do you make a rational decision about when thealarm should go off? What you have to do is to weigh upthe costs and beneﬁts of additional sleep. Each extra minutein bed gives you more read more..
101 INTRODUCING ECONOMICS• Efﬁciency in production ( productive efﬁciency). This iswhere production of each item is at minimum costs.Producing any other way would cost more.• Efﬁciency in consumption. This is where consumersallocate their expenditures so as to get maximum satis-faction from their income. Any other pattern of con-sumption would make people feel worse off.• Efﬁciency in specialisation and exchange. This is whereﬁrms specialise in producing goods for sale to read more..
1.1 WHAT DO ECONOMISTS STUDY?11You may not have realised it, but you probablyconsider opportunity costs many times a day. Thereason is that we are constantly making choices: whatto buy, what to eat, what to wear, whether to go out,how much to study, and so on. Each time we make achoice to do something, we are in effect rejecting doingsome alternative. This alternative forgone is theopportunity cost of the action we choose.Sometimes the opportunity costs of our actions arethe direct monetary read more..
121 INTRODUCING ECONOMICSThe social implications of choiceIn practice, the consequences of the choices that peoplemake may be neither efﬁcient nor equitable. Firms may useinefﬁcient techniques or be poorly managed; people oftenmake wrong decisions about what to buy or what job totake; governments may be wasteful or inefﬁcient in theiruse of tax revenues; there may be considerable inequalityand injustice.What is more, the effects of people’s choices often spillover to other people.

We measure units of food on one axis(in this case the vertical axis) and units of clothing on theother. The curve shows all the combinations of the twogoods that can be produced with all the nation’s resourcesfully and efﬁciently employed. For example, productioncould take place at point x, with 6 million read more..
141 INTRODUCING ECONOMICSmaterials differ one from another; and so on. Thus as thenation concentrates more and more on the production ofone good, it has to start using resources that are less andless suitable – resources that would have been better suitedto producing other goods. In our example, then, the pro-duction of more and more clothing will involve a growingmarginal cost: ever increasing amounts of food have to besacriﬁced for each additional unit of clothing produced.It is because read more..
1.1 WHAT DO ECONOMISTS STUDY?15Illustrating economic issues: the circularﬂow of goods and incomesThe process of satisfying human wants involves pro-ducers and consumers. The relationship between them is two-sided and can be represented in a ﬂow diagram (see Figure 1.5).The consumers of goods and services are labelled ‘house-holds’. Some members of households, of course, are alsoworkers, and in some cases are the owners of other factorsof production too, such as land. The producers of read more..
161 INTRODUCING ECONOMICSthe goods ﬂow; how the various factors of production arecombined to produce these goods; for whom the wages, dividends, rent and interest are paid out.Macroeconomics is concerned with the total size of theﬂow and what causes it to expand and contract.This ﬂow diagram, like the production possibility curve,can help us to distinguish between microeconomics andmacroeconomics.Microeconomics is concerned with the composition ofthe circular ﬂow: what combinations of read more..
1.2 DIFFERENT ECONOMIC SYSTEMS17It is nevertheless useful to analyse the extremes, in orderto put the different mixed economies of the real world intoperspective. The mixture of government and the marketcan be shown by the use of a spectrum diagram such asFigure 1.6. It shows where particular economies of the realworld lie along the spectrum between the two extremes.The diagram is useful in that it provides a simple pictureof the mixture of government and the market that exists invarious read more..
181 INTRODUCING ECONOMICSThe amount of resources it chooses to devote toinvestment will depend on its broad macroeconomicstrategy: the importance it attaches to growth as opposedto current consumption.• At a microeconomic level, it plans the output of eachindustry and ﬁrm, the techniques that will be used, andthe labour and other resources required by each industryand ﬁrm.In order to ensure that the required inputs are avail-able, the state would probably conduct some form ofinput–output read more..
1.2 DIFFERENT ECONOMIC SYSTEMS19It may distribute goods and services directly (forexample, by a system of rationing); or it may decide thedistribution of money incomes and allow individuals todecide how to spend them. If it does the latter, it maystill seek to inﬂuence the pattern of expenditure by setting appropriate prices: low prices to encourage con-sumption, and high prices to discourage consumption.Assessment of the command economyWith central planning, the government could take an read more..
201 INTRODUCING ECONOMICSrelative efﬁciency of two alternative techniques that usedifferent inputs, if there is no way in which the value ofthose inputs can be ascertained. For example, how can a rational decision be made between an oil-ﬁred and acoal-ﬁred furnace if the prices of oil and coal do notreﬂect their relative scarcity?• It is difﬁcult to devise appropriate incentives to encourage workers and managers to be more productivewithout a reduction in quality. For example, if read more..
1.2 DIFFERENT ECONOMIC SYSTEMS21Likewise the pattern of supply changes. For example,changes in technology may allow the mass production ofmicrochips at lower cost, while the production of hand-built furniture becomes relatively expensive.In all cases of changes in demand and supply, the result-ing changes in price act as both signals and incentives.A change in demand.A rise in demand is signalled by arise in price. This then acts as an incentive for supply to rise.What in effect is happening is read more..
221 INTRODUCING ECONOMICSThe fact that markets adjust so as to equate demand andsupply is our fourth ‘Threshold Concept’ (see panel).?1. Why do the prices of fresh vegetables fall when theyare in season? Could an individual farmer preventthe price falling?2. If you were the owner of a clothes shop, how would you set about deciding what prices to charge for each garment at the end-of-season sale?3. The number of owners of compact disc players hasgrown rapidly and hence the demand for read more..

241 INTRODUCING ECONOMICSEconomic interaction between people can take a numberof different forms. Sometimes it takes place in markets.For example, when goods are exchanged, there isinteraction between the consumer and the shop. Whensomeone is employed, there is interaction between the employer and the employee. When a ﬁrm buys rawmaterials, there is interaction between the purchasingﬁrm and the selling ﬁrm.In each case there is a mutual gain. If there wasn’t, theinteraction would not read more..

261 INTRODUCING ECONOMICSAlthough market forces can automatically equatedemand and supply, and although the outcomes of theprocess may often be desirable, they are by no meansalways so. Unbridled market forces can result in severeproblems for individuals, society and the environment.Markets tend to reﬂect the collective actions of indi-vidual consumers and ﬁrms. But when consumers and ﬁrms make their decisions, they may fail to takeaccount of the broader effects of their actions. Theymay read more..
1.3 THE NATURE OF ECONOMIC REASONING27Economics is one of the social sciences. So in what sense isit a science? Is it like the natural sciences such as physics andastronomy? What is the signiﬁcance of the word ‘social’ insocial science? What can economists do, and what is theirrole in helping governments devise economic policy?Economics as a scienceThe methodology employed by economists has a lot incommon with that employed by natural scientists. Bothattempt to construct theories or models read more..
281 INTRODUCING ECONOMICSIf the predictions are wrong, the ﬁrst thing to do is tocheck whether the deductions were correctly made. If theywere, the model must be either adapted or abandoned infavour of an alternative model with better predictive ability.Sometimes an economist will want to retain a modelwith poor predictive powers if it nevertheless helps to give some insight into the workings of the economy. Forexample, a model of some ideal world in which the goals of efﬁciency, growth and read more..
1.3 THE NATURE OF ECONOMIC REASONING29Section summary1. The methodology used by economists is similar tothat used by natural scientists. Economists constructmodels which they use to explain and predicteconomic phenomena. These models can be testedby appealing to facts and seeing how successfullythey have been predicted or explained by the model.Unsuccessful models can be either abandoned oramended.2. Being a social science, economics is concerned with human actions. Making accurate predictions read more..

Part B: Foundations ofMicroeconomicsIn the ﬁrst half of the book, we focus on microeconomics. Despite being ‘small eco-nomics’ – in other words, the economics of the individual parts of the economy, ratherthan the economy as a whole – it is still concerned with many of the big issues of today.To understand how the economy works at this micro level, we must understand howmarkets work. This involves an understanding of demand and supply.In Chapter 2, we look at how demand and supply read more..

342 SUPPLY AND DEMANDThe markets we will be examining are highly competitiveones, with many ﬁrms competing against each other. Ineconomics we call this perfect competition. This is whereconsumers and producers are too numerous to have anycontrol over prices: they are price takers.In the case of consumers, this means that they have toaccept the prices as given for the things that they buy. Onmost occasions this is true. For example, when you get tothe supermarket checkout you cannot start read more..
2.1 DEMAND35at a point in time). Thus we would talk about daily demandor weekly demand or annual demand or whatever.?Assume that there are 200 consumers in the market. Of these, 100 have schedules like Tracey’s and 100 haveschedules like Darren’s. What would be the total marketdemand schedule for potatoes now?The demand schedule can be represented graphically asa demand curve. Figure 2.1 shows the market demand curvefor potatoes corresponding to the schedule in Table 2.1.This price of read more..
362 SUPPLY AND DEMAND?1. Draw Tracey’s and Darren’s demand curves forpotatoes on one diagram. Note that you will use the same vertical scale as in Figure 2.1, but you will need a quite different horizontal scale.2. At what price is their demand the same?3. What explanations could there be for the quite different shapes of their two demand curves? (This question is explored in section 2.4 below.)Two points should be noted at this stage:• In textbooks, demand curves (and other curves too) read more..
2.1 DEMAND37?1. Do all these six determinants of demand affect both an individual’s demand and the market demand for a product?2. Relate each of these six determinants to the demandfor butter.Movements along and shifts in thedemand curveA demand curve is constructed on the assumption that‘other things remain equal’ (ceteris paribus). In other words,it is assumed that none of the determinants of demand,other than price, changes. The effect of a change in price is then simply illustrated by read more..
382 SUPPLY AND DEMANDTo distinguish between shifts in and movements alongdemand curves, it is usual to distinguish between a changein demand and a change in the quantity demanded. A shift inthe demand curve is referred to as a change in demand,whereas a movement along the demand curve as a result ofa change in price is referred to as a change in the quantitydemanded.?1. Assume that in Table 2.1 the total market demand for potatoes increases by 20 per cent at each price – due, say, to read more..
2.2 SUPPLY39Supply and priceImagine you are a farmer deciding what to do with your land.Part of your land is in a fertile valley. Part is on a hillside wherethe soil is poor. Perhaps, then, you will consider growingvegetables in the valley and keeping sheep on the hillside.Your decision will depend to a large extent on the pricethat various vegetables will fetch in the market and like-wise the price you can expect to get from sheep and wool.As far as the valley is concerned, you will plant the read more..
402 SUPPLY AND DEMAND• As ﬁrms supply more, they are likely to ﬁnd that beyonda certain level of output, costs rise more and morerapidly. In the case of the farm just considered, if moreand more potatoes are grown, then land progressivelyless suitable to potato cultivation has to be used. Thisraises the cost of producing extra potatoes. It is the samefor manufacturers. Beyond a certain level of output,costs are likely to rise rapidly as workers have to be paidovertime and as machines read more..
2.2 SUPPLY41Not all supply curves will be upward sloping (positivelysloped). Sometimes they will be vertical, or horizontal oreven downward sloping. This will depend largely on thetime period over which ﬁrms’ response to price changes isconsidered. This question is examined in the section on theelasticity of supply (see section 2.4 below) and in moredetail in Chapters 5 and 6.Other determinants of supplyLike demand, supply is not simply determined by price.The other determinants of supply read more..

2.3 PRICE AND OUTPUT DETERMINATION43Equilibrium price and outputWe can now combine our analysis of demand and supply.This will show how the actual price of a product and theactual quantity bought and sold are determined in a freeand competitive market.Let us return to the example of the market demand andmarket supply of potatoes, and use the data from Tables 2.1and 2.2. These ﬁgures are given again in Table 2.3.What will be the price and output that actually prevail?If the price started at 20p read more..
442 SUPPLY AND DEMANDA change in demandIf one of the determinants of demand changes (other thanprice), the whole demand curve will shift. This will lead to amovement along the supply curve to the new intersectionpoint.For example, in Figure 2.6, if a rise in consumer incomesled to the demand curve shifting to D2 , there would be ashortage of h− g at the original price Pe1. This would causeprice to rise to the new equilibrium Pe 2. As it did so, therewould be a movement along the supply curve read more..

462 SUPPLY AND DEMANDIf you are thinking of buying a house sometime in thefuture, then you may well follow the fortunes of thehousing market with some trepidation. In the late 1980sthere was a housing price explosion in the UK: in fact,between 1984 and 1989 house prices doubled. Afterseveral years of falling or gently rising house prices inthe early and mid-1990s, there was another boom from1996 to 2004, with house prices rising by 26 per centper year at the peak (in the 12 months to January read more..
2.3 PRICE AND OUTPUT DETERMINATION47The determinants of house pricesHouse prices are determined by demand and supply. If demand rises (i.e. shifts to the right) or if supply falls(i.e. shifts to the left), the equilibrium price of houseswill rise. Similarly, if demand falls or supply rises, theequilibrium price will fall.So why did house prices rise so rapidly in the 1980s,only to fall in the early 1990s and then rise rapidly againin the late 1990s and early 2000s? The answer liesprimarily in read more..

2.4 ELASTICITY49Assume that initially the supply curve is S1, and that itintersects with both demand curves at point a, at a price ofP1 and a quantity of Q1. Now supply shifts to S2. What willhappen to price and quantity? In the case of the less elasticdemand curve D, there is a relatively large rise in price (toP2 ) and a relatively small fall in quantity (to Q2 ): equilib-rium is at point b. In the case of the more elastic demandcurve D′, however, there is only a relatively small rise read more..

2.4 ELASTICITY51For example, if consumers buy 3 million units (Q ) at a priceof £2 per unit (P), they will spend a total of £6 million (TE).Total consumer expenditure will be the same as the totalrevenue (TR) received by ﬁrms from the sale of the product(before any taxes or other deductions).What will happen to consumer expenditure (and henceﬁrms’ revenue) if there is a change in price? The answerdepends on the price elasticity of demand.Elastic demandAs price rises so quantity demanded read more..

The second is where two curvesare drawn on the same diagram, as in Figure 2.10. Here wecan say that demand curve D is less elastic than demandcurve D′ at any given price. Note, however, that each ofthese two curves will still have different elasticities along its length.Although we cannot normally talk about the elasticity ofa whole read more..
542 SUPPLY AND DEMANDThe way we measure a proportionate change in quantity isto divide that change by the level of Q: i.e. ∆Q/Q. Similarly,we measure a proportionate change in price by dividingthat change by the level of P: i.e. ∆P/P. Price elasticity ofdemand can thus now be rewritten as:∆Q ÷∆PQPBut just what value do we give to P and Q? Consider the demand curve in Figure 2.15. What is the elasticity ofdemand between points m and n? Price has fallen by £2(from £8 to £6), but what read more..
2.4 ELASTICITY55*The measurement of elasticity: point elasticityRather than measuring elasticity between two points on ademand curve, we may want to measure it at a single point:for example, point r in Figure 2.16. In order to measurepoint elasticity we must ﬁrst rearrange the terms in the for-mula ∆Q/Q ÷∆P/P. By doing so we can rewrite the formulafor price elasticity of demand as:∆Q×P∆PQSince we want to measure price elasticity at a point onthe demand curve, rather than between two read more..
562 SUPPLY AND DEMAND(A knowledge of the rules of differentiation isnecessary to understand this box. See Appendix 1.)The following is an example of an equation for ademand curve:Qd= 60 − 15P+ P2(where Qd is measured in 000s of units). From this thefollowing table and the graph can be constructed.P60−15P+P2=Qd (000s)060−0+0=60160−15+1=46260−30+4=34360−45+9=24460−60+16=16560−75+25=10660−90+36=6Point elasticity can be easily calculated from such ademand equation using calculus. read more..
2.4 ELASTICITY57Price elasticity of supply (PS)When price changes, there will be not only a change in the quantity demanded, but also a change in the quantitysupplied. Frequently we will want to know just how respon-sive quantity supplied is to a change in price. The measurewe use is the price elasticity of supply.Figure 2.17 shows two supply curves. Curve S2 is moreelastic between any two prices than curve S1. Thus, whenprice rises from P1 to P2 there is a larger increase in quantitysupplied read more..
582 SUPPLY AND DEMANDOther supply curves’ elasticities will vary along theirlength. In such cases we have to refer to the elasticity eitherbetween two points on the curve, or at a speciﬁc point.Calculating elasticity between two points will involve thearc method. Calculating elasticity at a point will involvethe point method. These two methods are just the same forsupply curves as for demand curves: the formulae are thesame, only the term Q now refers to quantity suppliedrather than quantity read more..
2.4 ELASTICITY59As we have seen in the case of price elasticity ofdemand, elasticity measures the responsiveness of one variable (e.g. quantity demanded) to change inanother (e.g. price). This concept is fundamental tounderstanding how markets work. The more elasticvariables are, the more responsive is the market tochanging circumstances.Elasticity is more than just a technical term.

2.5 THE TIME DIMENSION61Price expectations and speculationIn a world of shifting demand and supply curves, prices donot stay the same. Sometimes they go up; sometimes theycome down.If prices are likely to change in the foreseeable future,this will affect the behaviour of buyers and sellers now.

3.1 THE CONTROL OF PRICES71Setting a maximum (low) priceThe government may set maximum prices to prevent themfrom rising above a certain level. This will normally bedone for reasons of fairness. In wartime, or times of famine,the government may set maximum prices for basic goodsso that poor people can afford to buy them.The resulting shortages, however, create further prob-lems. If the government merely sets prices and does notintervene further, the shortages will lead to the following:• read more..

Examples include things provided free at thepoint of use and products that are prohibited by thegovernment.2. If products are provided free to consumers, demandis likely to exceed supply. This is a particularproblem in the case of health care, where demand isgrowing rapidly.3. If products such as drugs are prohibited, an illegalmarket is read more..
3.4 AGRICULTURE AND AGRICULTURAL POLICY79Demand problems.Food, being a basic necessity of life,has no substitute. If the price of food in general goes up,people cannot switch to an alternative: they have either to pay the higher price or to consume less food. They might consume a bit less, but not much! The price elasticity for food in general, therefore, is very low (see Box 3.4).It is not quite so low for individual foodstuffs because if the price of one goes up, people can always switch to read more..
803 GOVERNMENT INTERVENTION IN THE MARKETThis very low income elasticity of demand has a crucialeffect on farm incomes. It means that a rise in nationalincome of 1 per cent leads to a rise in food consumption of considerably less than 1 per cent.

3.4 AGRICULTURE AND AGRICULTURAL POLICY83In open markets, however, a reduction in domestic supplycould simply lead to an increase in imports, with the resultthat the price would not rise to the desired level.

A thirdpacket gives him less extra utility still: marginal utility has fallen to 2 utils, giving a total utility of 13 utils (i.e. 11 + 2).By the time he has eaten 5 packets, he would rather not eat any more. A sixth actually reduces his utility (from14 utils to 13): its marginal utility is negative.The information in Table 4.1 is plotted in Figure 4.1.Notice the following points about the two curves:• The MU curve read more..

Inother words, it is likely that the marginal utility of moneydiminishes as income rises.Unless a good occupies only a tiny fraction of people’sexpenditure, a fall in its price will mean that their realincome has increased: i.e. they can afford to purchase moregoods in general. As they do so, the marginal utility of theirmoney will fall. We cannot, therefore, legitimately usemoney to measure utility in an read more..
984 BACKGROUND TO DEMANDThe rule for rational consumer behaviour is known asthe equi-marginal principle. This states that a consumerwill get the highest utility from a given level of incomewhen the ratio of the marginal utilities is equal to the ratioof the prices.

We can show how a change in either of these twodeterminants will affect the budget line.A change in incomeIf the consumer’s income (and hence budget) increases, thebudget line will shift outwards, parallel to the old one. Thisis illustrated in the last two columns of Table 4.3 and inFigure 4.9, which show the effect of a rise in the read more..

1124 BACKGROUND TO DEMAND• The good is now more expensive relative to other goods.Therefore consumers substitute alternatives for it. This isthe substitution effect.We can extend our arguments of Chapter 2 by demon-strating the income and substitution effects with the use ofindifference analysis.

5.1 THE SHORT-RUN THEORY OF PRODUCTION123is low, since the workers are spread too thinly. With moreworkers, however, they can work together – each, perhaps,doing some specialist job – and thus they can use the landmore efﬁciently. In Table 5.1, output rises more and morerapidly up to the employment of the third worker (point b).In Figure 5.1 the TPP curve gets steeper up to point b.After point b, however, diminishing marginal returns setin: output rises less and less rapidly, and the TPP read more..

We shall becoming across several other average and marginalconcepts later on. It is useful at this stage to examinethe general relationship between averages andmarginals.

KI 2p81265 BACKGROUND TO SUPPLYSection summary1. A production function shows the relationshipbetween the amount of inputs used and the amountof output produced from them (per period of time).2. In the short run it is assumed that one or morefactors (inputs) are ﬁxed in supply. The actual lengthof the short run will vary from industry to industry.3. Production in the short run is subject to diminishingreturns. As greater quantities of the variable factor(s)are used, so each additional unit of read more..
5.2 COSTS IN THE SHORT RUN127Likewise the replacement cost is irrelevant. That shouldbe taken into account only when the ﬁrm is consideringreplacing the machine.Costs and inputsA ﬁrm’s costs of production will depend on the factors of production it uses. The more factors it uses, the greaterwill its costs be. More precisely, this relationship dependson two elements:• The productivity of the factors. The greater their physical productivity, the smaller will be the quantity ofthem required read more..
1285 BACKGROUND TO SUPPLYTotal ﬁxed cost (TFC)In our example, total ﬁxed cost is assumed to be £12. Sincethis does not vary with output, it is shown by a horizontalstraight line.Total variable cost (TVC)With a zero output, no variable factors will be used. ThusTVC= 0. The TVC curve, therefore, starts from the origin.The shape of the TVC curve follows from the law ofdiminishing returns. Initially, before diminishing returnsset in, TVC rises less and less rapidly as more variable fac-tors are read more..
5.2 COSTS IN THE SHORT RUN129For example, assume that a ﬁrm is currently producing 1 000 000 boxes of matches a month. It now increases out-put by 1000 boxes (another batch): ∆Q = 1000. As a result,its total costs rise by £30: ∆TC = £30. What is the cost ofproducing one more box of matches? It is:∆TC=£30 = 3p∆Q 1000 (Note that all marginal costs are variable, since, by deﬁni-tion, there can be no extra ﬁxed costs as output rises.)Given the TFC, TVC and TC for each output, it is read more..

That is,if MC is less than AC, AC must be falling. read more..
KI 16p1205.3 THE LONG-RUN THEORY OF PRODUCTION131Section summary1. When measuring costs of production, we should be careful to use the concept of opportunity cost. In the case of factors not owned by the ﬁrm, theopportunity cost is simply the explicit cost ofpurchasing or hiring them. It is the price paid for them.In the case of factors already owned by the ﬁrm, it isthe implicit cost of what the factor could have earnedfor the ﬁrm in its next best alternative use.2. In the short run, some read more..
1325 BACKGROUND TO SUPPLYproduction increases. Clearly, if a ﬁrm is getting increasingreturns to scale from its factors of production, then as itproduces more it will be using smaller and smaller amountsof factors per unit of output. Other things being equal, thismeans that it will be producing at a lower unit cost.There are several reasons why ﬁrms are likely to experi-ence economies of scale. Some are due to increasing returnsto scale; some are not.Specialisation and division of labour.In read more..

They maybe able to obtain certain inputs cheaper by buying in bulk.Economies of scope.Often a ﬁrm is large because it produces a range of products. This can result in each individual product being produced more cheaply than if it was produced in a single-product ﬁrm.

1365 BACKGROUND TO SUPPLYThe isoquant shows the whole range of alternative waysof producing a given output. Thus Figure 5.5 shows notonly points a to e from the table, but all the intermediatepoints too.Like an indifference curve, an isoquant is rather like acontour on a map. And like contours and indifferencecurves, a whole series of isoquants can be drawn, each onerepresenting a different level of output (TPP). The higherthe output, the further out to the right will the isoquant be.Thus in read more..

Thus:MRS=∆K=2 = 2∆L 1The MRS between two points on the isoquant will equalthe slope of the line joining those two points. Thus inFigure 5.7, the MRS between points g and h is 2 (∆K/∆L =2/1). But this is merely the slope of the line joining points gand h (ignoring the negative sign).When the isoquant is bowed in towards the origin, the slope of the isoquant will diminish read more..
1385 BACKGROUND TO SUPPLY?1. What will happen to an isocost if the prices of bothfactors rise by the same percentage?2. What will happen to the isocost in Figure 5.8 if thewage rate rises to £15 000?The slope of the isocost equals:PLPKThis can be shown in the above example. The slope of the isocost in Figure 5.8 is 15/30 = 1/2. But this is PL/PK (i.e. £10 000/£20 000).Isoquants and isocosts can now be put on the same dia-gram.

5.3 THE LONG-RUN THEORY OF PRODUCTION139If the prices of factors change, new isocosts will have tobe drawn. Thus in Figure 5.10, if the wage rate goes up, lesslabour can be used for a given sum of money. The isocostwill swing inwards round point x. The isocost will getsteeper. Less labour will now be used relative to capital.Postscript: Decision making in differenttime periodsWe have distinguished between the short run and the longrun.

The relationship between long-run andshort-run average cost curvesTake the case of a ﬁrm which has just one factory and faces a short-run average cost curve illustrated by SRAC1 inFigure 5.13.In the long run, it can build more factories.

Thus with two factoriesit will face SRAC2; with three factories SRAC3, and so on.Each SRAC curve read more..
*Derivation of long-run costs from anisoquant map4Cost curves are drawn on the assumption that, for any output, the least-cost combination of factors is used: thatis, that production will take place at the tangency point of the isoquant and an isocost, where MPPL /MPPK = PL/PK:i.e. where MPPL/PL= MPPK/PK.

1445 BACKGROUND TO SUPPLYTwo of the most important studies of economies ofscale are those made by C. F. Pratten5 in the late 1980sand by a group advising the European Commission6 in1997. Both studies found strong evidence that manyﬁrms, especially in manufacturing, experiencedsubstantial economies of scale.In a few cases, long-run average costs fellcontinuously as output increased. For most ﬁrms,however, they fell up to a certain level of output andthen remained constant.The extent of read more..
Average revenue (AR)Average revenue is the amount the ﬁrm earns per unit sold.Thus:AR= TR/QSo if the ﬁrm earns £5000 (TR) from selling 1000 units (Q),it will earn £5 per unit. But this is simply the price! Thus:AR= P(The only exception to this is when the ﬁrm is selling itsproducts at different prices to different consumers. In thiscase, AR is simply the (weighted) average price.)Marginal revenue (MR)Marginal revenue is the extra total revenue gained by sell-ing one more unit (per time read more..
1465 BACKGROUND TO SUPPLYWe now need to see how each of these three revenue con-cepts (TR, AR and MR) varies with output. We can show thisgraphically in the same way as we did with costs.The relationships will depend on the market conditionsunder which a ﬁrm operates. A ﬁrm that is too small to beable to affect market price will have different-shaped revenuecurves from a ﬁrm that is able to choose the price it charges.Let us examine each of these two situations in turn.Revenue curves when read more..
5.5 REVENUE147Revenue curves when price varies with outputThe three curves (TR, AR and MR) look quite different whenprice does vary with the ﬁrm’s output. If a ﬁrm has a relativelylarge share of the market, it will face a downward-slopingdemand curve. This means that if it is to sell more, it mustlower the price. It could also choose to raise its price. If itdoes so, however, it will have to accept a fall in sales.Average revenueRemember that average revenue equals price. If, read more..

It is a curve that rises at ﬁrst and then read more..
5.6 PROFIT MAXIMISATION149Shifts in revenue curvesWe saw in Chapter 2 that a change in price will cause amovement along a demand curve. It is similar with revenuecurves, except that here the causal connection is in theother direction. Here we ask what happens to revenuewhen there is a change in the ﬁrm’s output. Again the effectis shown by a movement along the curves.A change in any other determinant of demand, such astastes, income or the price of other goods, will shift thedemand curve. By read more..

Fill in the missing ﬁgures (without referring to Table 5.8 or 5.9).2. Why are the ﬁgures for MR and MC entered in thespaces between the lines in Table 5.10?Finding the maximum proﬁt that a ﬁrm can make is a two-stage process. The ﬁrst stage is to ﬁnd the proﬁt-maximising output. To do this we use the MC and MRcurves. The second stage is to read more..
5.6 PROFIT MAXIMISATION151Stage 2: Using average curves to measure the sizeof the proﬁtOnce the proﬁt-maximising output has been discovered,we use the average curves to measure the amount of proﬁt atthe maximum. Both marginal and average curves corres-ponding to the data in Table 5.10 are plotted in Figure 5.21.First, average proﬁt (AΠ ) is found. This is simply AR−AC. At the proﬁt-maximising output of 3, this gives a ﬁgurefor AΠ of £6 − £42/3= £11/3. Then total proﬁt is read more..

If they earn less than normal proﬁt,then after a time they will consider leaving and using theircapital for read more..
Loss minimisingIt may be that there is no output at which the ﬁrm canmake a proﬁt. Such a situation is illustrated in Figure 5.22:the AC curve is above the AR curve at all levels of output.In this case, the output where MR= MC will be the loss-minimising output. The amount of loss at the point whereMR= MC is shown by the shaded area in Figure 5.22.Whether or not to produce at allThe short run.Fixed costs have to be paid even if the ﬁrmis producing nothing at all.

1626 PROFIT MAXIMISING UNDER PERFECT COMPETITION AND MONOPOLYSo, under perfect competition, the ﬁrm’s supply curve isentirely dependent on costs of production. This demon-strates why the ﬁrm’s supply curve is upward sloping.Given that marginal costs rise as output rises (due to dimin-ishing marginal returns), a higher price will be necessary toinduce the ﬁrm to increase its output.Note that the ﬁrm will not produce at a price belowAVC.

We also look at some alternative measures ofnational income.The product method of measuring GDPThis approach simply involves adding up the value ofeverything produced in the country during the year: theoutput of cars, timber, lollipops, shirts, etc.; and all themyriad of services such as football matches, haircuts, busrides and insurance read more..
APPENDIX: CALCULATING GDP389here is that some goods start being produced before the yearbegins. Thus when we come to work out GDP, we mustignore the values that had previously been added to stocksof raw materials and goods. Similarly, other goods are onlysold to the consumer after the end of the year. Neverthelesswe must still count the values that have been added duringthis year to these stocks of partially ﬁnished goods.A ﬁnal problem concerned with stocks is that they mayincrease in value read more..

APPENDIX: CALCULATING GDP391When working out GDP, however, we add in these taxesand subtract these subsidies to arrive at a market pricevaluation.The expenditure method of measuring GDPThe ﬁnal approach to calculating GDP is to add up allexpenditure on ﬁnal output (which will be at marketprices).

Part F: The World Economy‘Globalisation’ is a word frequently used nowadays. But it neatly captures one of the keyfeatures of economics today: that it is global in nature. International trade has grown at amuch faster rate than the levels of national output in any country. International ﬁnancialﬂows have grown faster still. The result is that economies around the globe are inter-meshed, and what happens in one country can have profound effects on others.In Chapters 23 and 24 we look at read more..

This involves the same techniqueas simple differentiation but applied to just the one vari-able that is not held constant.Thus to ﬁnd the rate of change of costs with respect toquantity in equation (8), we differentiate the equation withrespect to Q and ignore the W term. We ignore it as it isheld constant and is thus treated like the constant (20)term in the equation. Using the rules of differentiation, thepartial read more..

THRESHOLD CONCEPTSPage1. Choice and opportunity cost.82. Rational decision making involves choices at the margin.103. People respond to incentives. It is important, therefore, that these have the desired effect.214. Markets equate demand and supply.225. People gain from voluntary economic interaction.246. Markets may fail to meet social objectives.267. Governments can sometimes improve market outcomes.268. Elasticity: of a variable to a change in a determinant.599.

T:2THRESHOLD CONCEPTS AND KEY IDEAS8. Equilibrium is the point where conﬂicting interests are balanced. Only at this point is the amount that demanders are willing to purchase the same as the amount that suppliers are willing to supply. It is a point that will be reached automatically in a free market through the operation of the price mechanism.439. Elasticity. The responsiveness of one variable (e.g. demand) to a change in another (e.g. price). This concept isfundamental to understanding how read more..
THRESHOLD CONCEPTS AND KEY IDEAST:328. Externalities are spillover costs or beneﬁts. Where these exist, even an otherwise perfect market will fail to achieve social efﬁciency.30029. The free-rider problem. People are often unwilling to pay for things if they can make use of things that other people have bought. This problem can lead to people not purchasing things that would be to the beneﬁt of them and other members of society to have.30330. The problem of time lags. Many economic actions read more..
