How are prices determined?If an economy runs on the lines of the purely competitive market of free enterprise, then what is produced and t

10、he prices at which the products are sold depend upon the choices and decisions made by consumers and producers.The price mechanism is the process by which prices rise and fall as a result of changes in demand and supply, and thereby acts as a signal to producers to guide them on their production pla

11、ns.If our economy were entirely competitive and there were no restrictions at all, then the market forces, or price mechanism, would operate freely. The only things that would be produced would be those goods for which consumers were willing to pay sufficient to make it worthwhile for the producers

12、to put them on the market. The demand for a product and the price at which it can be sold indicate to the producer the best way to allocate resources in order to make a profit.2.1 Price mechanismDemand means the quantity which buyers are willing to purchase at a given price over a given period of ti

13、me. Effective demand means a desire to obtain an article accompanied by the ability and willingness to pay for it at the price asked. In economics, when we speak of demand, we are usually referring to effective demand.2.2 Demand and effective demandLaw of demand Buyers are likely to buy more of an i

This is the conventional way of drawing a demand and supply graph. As prices fall, a larger quantity of a good is demanded. The

16、typical demand curve slopes down from left to right. This indicates that consumers buy more of a good at lower prices and less at higher prices, but at very low prices demand does not necessarily increase. This is sometimes called an expansion or contraction, or a movement along the curve.3.2 Demand

18、pical supply curve slopes down from right to left. This indicates that suppliers or sellers supply or sell more of a good at higher prices and less at lower prices. This is called a movement along the curve.4.2 Supply curvesA compromise between how much and at what price the seller decides to sell a

19、nd the consumers plans to buy must be arrived at. This is called the equilibrium price and is the price at which the buyer is prepared to buy the quantity which the seller is prepared to sell at that price, so that the market is cleared and there is no surplus and no shortage.4.3 Equilibrium price 5

A change in the price of a good results in a movement along an existing demand curve.Price has remained unchanged but there has been a change in demand

22、caused by factors other than price. The demand curve could shift to the left or right if there is a change in any of these conditions other than price, influencing people to buy less or more of a commodity even if the price remains unchanged.5.2 Changes in demand6.1 Influences which can change suppl

It equals the quantity of output the firm produces times the price at which it sells its output.Total cost The amount t

29、hat the firm pays to buy inputs is called its total cost. Profit Profit is a firms total revenue minus its total cost. That is, Profit=Total revenueTotal cost.2.1 Total revenue, total cost, and profit 2.2.1 Definition of opportunity costs2.2.2 Explicit and implicit costs2.2.3 Difference between econ

30、omists and accountants2.2 Costs as opportunity costsThe opportunity cost of an item refers to all those things that must be forgone to acquire that item. When economists speak of a firms cost of production, they include all the opportunity costs of making its output of goods and services.2.2.1 Defin

31、ition of opportunity costsExplicit costs Some costs require the firm to pay out some money, they are called explicit costs. Implicit costs Some of a firms opportunity costs, called implicit costs, do not require a cash outlay.2.2.2 Explicit and implicit costsThe distinction between explicit and impl

32、icit costs highlights an important difference between how economists and accountants analyze a business. Economists are interested in studying how firms make production and pricing decisions. Because these decisions are based on both explicit and implicit costs, economists include both when measurin

33、g a firms costs. By contrast, accountants have the job of keeping track of the money that flows into and out of firms. As a result, they measure the explicit costs but often ignore the implicit costs.2.2.3 Difference between economists and accountantsAn important implicit cost of almost every busine

34、ss is the opportunity cost of the financial capital that has been invested in the business.2.3 The cost of capital as an opportunity cost2.4.1 Economic profit2.4.2 Accounting profit2.4.3 Normal profit2.4 Economic profit versus accounting profitAn economist measures a firms economic profit as the fir

35、ms total revenue minus all the opportunity costs (explicit and implicit) of producing the goods and services sold. For a business to be profitable from an economists standpoint, total revenue must cover all the opportunity costs, both explicit and implicit.2.4.1 Economic profitAn accountant measures

36、 the firms accounting profit as the firms total revenue minus only the firms explicit costs. Notice that because the accountant ignores the implicit costs, accounting profit is usually larger than economic profit. 2.4.2 Accounting profitEconomists call a zero economic profit as normal profit. Normal

37、 profit is the minimum profit necessary to keep a firm in operation. Zero economic profit signifies there is just enough total revenue to pay the owners for all explicit and implicit costs. Stated differently, there is no benefit from reallocating resources to another use.2.4.3 Normal profit3.1 Fixe

38、d and variable costs3.2 Average and marginal cost3.3 Private costs and social costs3. The various measures of costFixed costs Some costs, called fixed costs, do not vary with the quantity of output produced. They are incurred even if the firm produces nothing at all.Variable costs Some of the firms

39、costs, called variable costs, change as the firm alters the quantity of output produced.Total cost A firms total cost is the sum of fixed and variable costs. 3.1 Fixed and variable costs3.2.1 Average total cost3.2.2 Average fixed cost 3.2.3 Average variable cost 3.2.4 Marginal cost 3.2 Average and m

40、arginal costAverage total cost divided by the quantity of output is called average total cost. Because total cost is just the sum of fixed and variable costs, average total cost can be expressed as the sum of average fixed cost and average variable cost.Average total cost tells us the cost of a typi

41、cal unit of output if total cost is divided evenly over all the units produced. 3.2.1 Average total costAverage fixed cost is the fixed cost divided by the quantity of output. 3.2.2 Average fixed cost Average variable cost is the variable cost divided by the quantity of output. 3.2.3 Average variabl

42、e cost Marginal cost=Change in total cost/Change in quantityMarginal cost tells us the increase in total cost that arises from producing an additional unit of output. 3.2.4 Marginal cost3.3.1 Private costs3.3.2 Social costs 3.3 Private costs and social costsThe private costs of a firm are the sum of

43、 the explicit and implicit costs that it incurs. 3.3.1 Private costsThe social costs of a firm are those that society in general bears because of the firms activities. Social costs would include the private costs of a firm, since presumably all of the firms resources could be used elsewhere in produ

44、cing goods of value to (at least some members of) society. However, social costs would also include costs paid for by society but not by the firm, even though such costs were a result of production by the firm. 3.3.2 Social costs(1) What is the relationship between a firms total revenue, profit, and

45、 total cost?(2) What is the relationship between a firms total cost, average total cost, and marginal cost?(3) Explain the opportunity cost.(4) What is the difference between economic profit and accounting profit.(5) Give an example of a social cost which is paid for by society but not by the firm b

48、Why monopolies arise2.1.1 Definition of Monopoly2.1.2 Fundamental cause of Monopoly2.1 Definition and the fundamental cause of MonopolyA firm is a monopoly if it is the sole seller of its product and if its product does not have close substitutes. 2.1.1 Definition of MonopolyThe fundamental cause of

49、 monopoly is barriers to entry: A monopoly remains the only seller in its market because other firms cannot enter the market and compete with it. Barriers to entry, in turn, have three main sources: A key resource is owned by a single firm; The government gives a single firm the exclusive right to p

50、roduce some good or service; The costs of production make a single producer more efficient than a large number of producers.2.1.2 Fundamental cause of Monopoly2.2.1 Monopoly Resources2.2.2 Government-Created Monopolies2.2.3 Natural Monopolies2.2 Three main sources for barriers to entryThe simplest w

51、ay for a monopoly to arise is for a single firm to own a key resource.Although exclusive ownership of a key resource is a potential cause of monopoly, in practice monopolies rarely arise for this reason. Actual economies are large, and resources are owned by many people. Indeed, because many goods a

52、re traded internationally, the natural scope of their markets is often worldwide. There are, therefore, few examples of firms that own a resource for which there are no close substitutes.2.2.1 Monopoly ResourcesIn many cases, monopolies arise because the government has given one person or firm the e

53、xclusive right to sell some good or service. Sometimes the monopoly arises from the sheer political clout of the would-be monopolist. At other times, the government grants a monopoly because doing so is viewed to be in the public interest. The patent and copyright laws are two important examples of

54、how the government creates a monopoly to serve the public interest.2.2.2 Government-Created MonopoliesAn industry is a natural monopoly when a single firm can supply a good or service to an entire market at a lower cost than could two or more firms. A natural monopoly arises when there are economies

55、 of scale over the relevant range of output. In this case, a single firm can produce any amount of output at least cost. That is, for any given amount of output, a larger number of firms lead to less output per firm and higher average total cost.2.2.3 Natural Monopolies3.1 Increasing competition wit

56、h antitrust laws3.2 Regulation3.3 Public ownership3.4 Doing nothing3. Public policy toward monopoliesThe government derives its power over private industry from the antitrust laws, a collection of statutes aimed at curbing monopoly power.The antitrust laws give the government various ways to promote

57、 competition. They allow the government to prevent mergers.Antitrust laws have costs as well as benefits. Sometimes companies merge not to reduce competition but to lower costs through more efficient joint production. These benefits from mergers are sometimes called synergies.3.1 Increasing competit

58、ion with antitrust lawsMeans regulating the behavior of monopolists. This solution is common in the case of natural monopolies, such as water and electric companies. These companies are not allowed to charge any price they want. Instead, government agencies regulate their prices.3.2 RegulationThat i

59、s, rather than regulating a natural monopoly that is run by a private firm, the government can run the monopoly itself. This solution is common in many European countries, where the government owns and operates utilities such as the telephone, water, and electric companies. In the United States, the

60、 government runs the Postal Service. The delivery of ordinary First Class mail is often thought to be a natural monopoly.3.3 Public ownershipEach of the foregoing policies aimed at reducing the problem of monopoly has drawbacks. As a result, some economists argue that it is often best for the govern
