In last section, We neglect price discrimination (such as dumping) in the imperfect competitive model which give rise international trade.2Clips: 中国鞋如何迎战反倾销连环箭3一、Dumping(倾销)1.The Economics of DumpingIn reality, firms do not charge the same price for goods that are exported and solddomestically, it is the price discrimination.1)Price discrimination: The practice of chargingdifferent customers different prices.Dumping is the most common form of price discrimination in international trade.42)Definition of DumpingIt is a pricing practice in which a firm chargesa lower price for an exported good than itdoes for the same good sold domesticallyIt is a controversial issue in trade policy and is widely regarded as an unfair practice ininternational trade.53)Dumping can occur only if two conditions aremet:First, the industry must be Imperfectly competitive industry, so that firms set prices rather than taking prices as given.Second, market must be segmented, so that domestic residents cannot easily purchasegoods intended for export(transport costs and protectionist trade barriers).62.A monopolistic firm gets profits by dumping An example below help to show dumping can be a profit-maximizing strategy by Figure 6-8. To maximize profits, the firm must set marginal revenue equal to marginal cost ineach market.We assume that the firm can sell as much as it wants at the Pin the foreign market.FOR7The firm sell Qin the domestic market andDOMsell Q MONOPOLY- Q DOM in the foreign market .will be demanded domestically The quantity QDOMat price of P, which is above the export priceDOMP FOR . Thus the firm is indeed dumping, sellingmore cheaply abroad than at Home.9The reason the firm chooses to dump is the difference in the responsiveness of sales toprice in the export and domestic markets(P143).103.Reciprocal Dumping1)Reciprocal Dumping is a situation in whichdumping leads to two-way trade in the same product.The reason is that if it tries to sell more it will drive down the price on its existing domestic sales. But dumping has the negative effect on the price of existing sales in the foreign sales.112)It increases the volume of trade in goods thatare not quite identical.3)Its net welfare effect is ambiguous:It wastes resources in transportation.It creates some competition.12Case studyThe dumping cases against China in 2005.13世贸组织的一项报告显示,2005年上半年全球实施反倾销调查数量为96起,去年同期为106起;申请反倾销措施的数量为53起,去年同期为58起。

A Level Model A nswer: Theory of the FirmIn production, a distinction is made between short-run cost curves and long-run cost curves. Using appropriate cost curve diagrams, explain this distinction. (12 marks) The costs that a firm incurs can be separated into fixed costs and variable costs, which together make up a firm’s total costs. Fixed costs remain constant regardless of quantity output – for example, the rent paid on a factory used when producing a good. Variable costs change as output increases or decreases. An example is the wage cost of labour. To produce more output, the firm hires more labour, and has increased wage costs. The more variable inputs a firm uses, the greater the total variable costs.In microeconomics, the ‘short-run’ refers to the period of time in which at least one factor of production (usually land, labour and/or capital) is fixed. For example, the time it takes for a contract with a property owner to end before the firm can move to a different location.Figure 1 Short-run cost curvesIn Figure 1, the AFC curve indicates that average fixed cost falls continuously as output increases, because it represents the amount of total fixed costs divided by an ever growing quantity of output. The average variable cost, average total cost and marginal cost curves,although different from one other, all follow the same general pattern: at first they fall, reach a minimum, and then they begin to rise.Marginal cost rises with the amount of output produced, reflecting the property of diminishing marginal product – as units of one input are added (with other inputs held constant) a point will be reached where the resulting additions to output will begin to decrease (marginal product will decline). Consider the limited size of the factory discussed earlier – we can keep adding more and more variable inputs (such as labour) but, constrained by the limited space, we will eventually see no further increases in output and output may even start to fall due to overcrowding of the fixed factor(s). Thus the cost of producing an additional cost continues to rise even though the firm may be gaining no benefit in terms of increased output.In the ‘long-run’, all factors of production become variable – in the example given, the firm can move to a bigger or less expensive factory. Because many costs are fixed in the short run but variable in the long run, a firm’s long-run cost curves differ from its short-run cost curves. As the firm plans its future activities in the long run, it can select any size or scale of operation depending on the quantity of output it is aiming for. The particular size it selects will be the one that minimises costs for that level of output. The long-run average total curve is the curve that is tangent to each of the short-run cost curves. Long run average total costs represent the lowest possible average cost, or cost per unit of output, for every level of output, when all resources are variable.Figure 2 Long-run average total cost curvesThe U-shape of the long-run ATC curve is a result of economies and diseconomies of scale.Economies of scale refer to the benefits in terms of falling average total cost gained from large scale production, occurring for a number of reasons. Firstly, as the scale of productionincreases, more workers must be employed, allowing for greater labour specialisation. Aseach worker specialises in a narrower range of tasks that make use of existing skills, anddevelop skills through repetition, worker efficiency is increased, allowing output to beproduced at a lower average cost.Larger scales of production allow for more managers to be employed, each of whom can bespecialised in a particular area, again resulting in greater efficiency and lower average cost. Large machines are often more efficient than smaller ones. However, a small firm with a small volume of output cannot make effective use of large machines, and so is forced to use smaller, less efficient ones. Some machines are only available in large sizes that require large volumes of output in order to be used effectively. Some production processes, such as mass production assembly lines, require large volumes of inputs and output in order to be used efficiently. Costs of certain activities such as advertising, design, research and development result in lower average costs if they can be spread over large volumes of output.However, as a firm increases its scale of production, costs per unit of output may eventually start to increase. As a firm grows, management faces co-ordination difficulties. Communication and decision-making will be slower. Staff may feel alienated in a large organisation and unless they are monitored effectively, the quality and output of their work may decline.Evaluate the view that productive and allocative efficiency is more likely to be achieved in perfectly competitive industries than monopolies. [13 marks]Productive efficiency occurs when production takes place at the lowest possible cost. Allocative efficiency occurs when firms produce the particular combination of goods and services that consumers prefer. It is achieved when price equals marginal cost. This is because the price paid by consumers to acquire a good reflects the marginal benefit they derive from consumption of an additional of the good and shows the amount of money they are willing to pay to buy one more unit.Marginal cost measures the value, or opportunity cost, of the resources used to produce one extra unit of the good. When price is equal to marginal cost, therefore, what consumers are prepared to pay to get one more unit and what it costs to produce one more unit are equal.Figure 3 Long-run equilibrium position of a firm in a perfectly competitive industry.Figure 3 shows the firm in a competitive industry earns zero economic profit in the long-run.Thus, the perfectly competitive firm achieves both allocative and productive efficiency. As the competitive firm must accept the market price, price equals average revenue andmarginal revenue and the supply curve facing the firm is perfectly elastic at the market price.The profit-maximising level of output is set where price (marginal revenue) equals marginalcost (allocative efficiency is achieved) and average total cost is minimised (productiveefficiency is achieved).The monopolist, as the only supplier in the market, can restrict supply and charge a higher price to consumers to maximise profit (see Figure 4).Figure 4 Monopoly price, output and profitHigher prices and lower output are not in consumers’ best interests. The area BCD represents this welfare loss, indicating there is allocative inefficiency. Some monopolists achieve productive efficiency because they may output where average total cost is minimised (although this is not always the case). ‘Natural’ monopolies exist when an industry can only support one firm producing at efficient scale – for example, utility companies such as tap water providers.Lack of competition in monopoly may lead to higher costs (‘X-inefficiency’). Whereas in perfect competition firms are under constant pressure to produce with the lowest possiblecosts to survive, in monopoly the lack of competition may make the monopolist lessconcerned about keeping costs low. Higher costs may arise due a poorly motivatedworkforce and lack of innovation due to lack of competitive pressure.Nevertheless, monopolies can be desirable from the perspective of consumers and society.Why a monopoly may be desirable. Monopolists’ economic profits can provide them with theability to finance large research and development projects. In fact, this is the rationale forawarding firms patent protection for a period of time.Economies of scale are an argument in favour of large firms that can achieve lower costs asthey grow in size. If monopolists pursue research and development that leads totechnological innovation, they may adopt production processes and technologies that make them more efficient and thus able to produce at a lower cost, which could be passed toconsumers in the form of lower prices. Therefore, it remains disputable that perfectlycompetitive firms are always more likely to achieve allocative and productive efficiency thanmonopolists.。

as the U.S. industry’s output falls, its costs will rise.•In the end, all button production will be in China.concentration of button production2015/2016International Trade24External Economies and International Trade–causes•What might cause one country to have an initial advantage from having a lower price?•One possibility is comparative advantage due to underlying differences in technology and resources( Ricardo model;
