Advanced International Trade Lecture 3 Prof Tybout September 12 2006 Lecture outline Winners and losers a closer look Production possibility frontiers Autarky equilibrium when output isn t fixed Trade and the gains from specialization when output isn t fixed Relevant reading Caves Frankel and Jones chapter 2 A brief recap Last time we considered an economy that could produce a xed amount ofwheat and a fixed amount of cloth Some households specialized in the production ofone good others in the other good We characterized the autarky equilibrium then we introduced another economy and characterized the trading equilibrium At any relative price of Wheat the demand for wheat and cloth is C A determined as the tangency point with a social indifference curve C1 V 5 P2 P1 P0 W1 W W Sup ly of wheat By trying different relative prices for vxneat one can trace out a demand curve for wheat Demand for wheat matches supply for wheat at only one relative price This price reflects the slope of the social indifference curve that passes through the production point Demand for wheat l The trading equilibrium Foreign demand Home demand Global demand home foreign demand W W W V7W Global demand falls short of global supply at p0 and global demand exceeds global supply at p1 so the free trade price must lie between these two prices Winners and Losers A Closer Look The relative price of

the price ofwheat rises the weavers budget constraint pivots inward Winners and Losers A Closer Look Opening to trade hurts weavers because it drives down the relative price of cloth causing their budget line to pivot inward C n C l Winners and Losers A Closer Look Could the winners compensate the losers Suppose prior to trade we were to reallocate productive capacity between the two types of households so that each household could produce the consumption bundle it chooses in autarky This must be feasible because markets clear in the autarky equilibrium Winners and Losers A Closer Look Winners and Losers A Closer Look Now opening to trade generates gains for everyone C 5A pworld I70 V7 W Both types of household are able to reach higher indifference curves at the free trade prices Winners and Losers A Closer Look C 7 world Winners and Losers A Closer Look Instead of reallocating endowments of wheat and cloth before opening to trade the government could achieve the same outcome by taking income away from farmers and giving it to weavers after opening to trade C Trade without redistribution puts households on the red budget lines i pworld I70 V7 Winners and Losers A Closer Look Instead of reallocating endowments of wheat and cloth before opening to trade the government could achieve the same outcome by taking income away from farmers and giving it to weavers after opening to trade A Taxing farmers income shifts their posttrade budget line in and generate revenue with which to subsidize pworld 70 Winners and Losers A Closer Look Aside from equity issues why would a government want to do this Do we see this type of policy in practice Gains from Specialization Thus far we have seen that there are gains from trade when a country doesn t adjust the mix of goods it produces Gains from exchange Next we will see that if an economy s production mix adjusts in response to changes in relative prices there are additional gains from trade Gains from specialization Production Possibility Frontiers Production possibility frontiers PPF show the maximum amount of any one good that an economy can produce at each feasible production level for the other

Equilibrium PoPs 3935 0905 QoQs Note Equilibrium relative prices can be found by focusing on a single market as we did last lecture or by equating relative supply to relative demand as we do here 29 Autarky Equilibrium QB Slope p Trading Equilibrium Suppose the world price of goats exceed the autarky price and this country opens to trade QB Trading Equilibrium Things to note Since the economy reaches a higher SIC with trade it would have possible to make everyone better off with trade by sharing the gains But without income redistribution trade creates some losers Who are they In the trading equilibrium the marginal rate of transformation and the marginal rate of substitution both match the relative price ratio In the trading equilibrium the value of exports matches the value of imports The fact that the economy can adjust its production mix leads to a second basic source of gains from trlacde g ains from specialization refer to graph next sI e Gains from Trade The total gain

International Trade Lecture 19 Prof Tybout November 4 2006 Outline Quotas The MultiFiber Arrangement Trade policy versus domestic policy Shortrun effects of import competition who loses hisherjob Policy issues Relevant reading Caves Frankel and Jones chaps 10 and 13 The Multifiber Arrangement Background A patchwork of bilateral trade agreements mainly involving the US Canada the EU and Norway as importers of textiles and apparel and various developing countries as exporters Started with quotas on Japanese exports in 1957 codified as MFA in 1974 Imposed quantitative restrictions quotas country by country on textile and apparel exports to each importing country Tariffequivalent of quotas in the mid1980s was estimated at 56 percent for the US and 33 percent for the EU The Multifiber Arrangement WTO members signed the Agreement on Textiles and Clothing ATC effective in 1995 which mandated a phaseout ofthe MFA quotas over the period 19952005 The phaseout Stage 1 1995 VVTO members must integrate 16 percent of the total volume oftheir 1990 imports Stage 2 1998 must integrate an additional 17 percent Stage 3 2002 an additional 18 percent Stage 4 2005 remaining 49 percent Cost of the MFA in Europe EU consumers paid roughly 12 billion more in 1997 for textile and clothing products than they would have in the absence of the quotas abc About 65 billion ofthis represented quota rents that were passed on to the holders ofthe import licenses 0 some of the remainder represented extra producer surplus a and a substantial amount represents ef ciency loss The annual cost of each job saved in the EU textiles and clothing industries by delayed implementation was 28000 for the textile industry and 41000 for the clothing industry MFA phaseout Although the developing world should have been happy overall about the elimination of MFA quotas many countries including lndia Egypt and Pakistan worried that free trade would make things worse Why MFA phaseout Did the phaseout affect trade ows The United States Commerce Department said Friday that in the first three months of the year United States imports of textile and apparel products from China rose more than percent from a year ago NYT April 4 2005 In some crucial categories previously governed by the old MFA like underwear cotton trousers and cotton knit shirts the increases were even more stark jumps of as much as 2000 percent NYT April 4 2005 Afterthe lifting of worldwide textile trade quotas last January Chinese textile exports to Euro e ballooned 82 percent in the first four months compared wit the same period last year according to Chinese customs statistics NYT September 6 2005 MFA phaseout Government reactions The Bush administration announced on Friday that it would impose new quotas on cotton shirts trousers and underwear NYT May 14 2005 The proposed new restrictions would limit growth in Chinese imports of the affected garments to 75 percent above the level that exports reached in the previous 12 months the lowest possible undertrading rules NYT May 17 2005 The move toward new quotas on Chinese clothing exports is a quotbetrayal of the fundamental spirit of trade liberalization espoused by the WTOquot said a spokesman for China s Ministry of Commerce quotThe Chinese government reserves the right to adopt further measures under the WTO framework NYT May 17 2005 MFA phaseout European garment makers complained that their livelihood was in peril But after an agreement was signed in June to limit export growth of Chinesemade clothes to 8 percent to 125 percent a year European retailers complained that orders they had placed before the deal took effect were held up at ports because quotas for 2005 had already been filled NYT September 6 2005 China and Europe agreed to share the burden of absorbing the unlicensed shipments stranded at European ports China would subtract halfthe amount from its export quotas for subsequent years and Europe would absorb the other half NYT September 6 2005 Tariffs versus production taxes or subsidies Slope 1tp X lfthe objective is to move the production point from A to B a tariff on X imports a tax on Yproduction or a subsidy

versus domestic policies The general point Tariffs are a blunt instrument They affect both consumption and production Ifthe objective is to in uence on one ofthese better policy tools are available To affect production use a production tax or subsidy To affect consumption use a consumption tax or subsidy Subsidy versus tariff for an import competing industry m Example Bush imposed a 30 percent tariff on imports of many types of steel in 2002 Steel users were hurt by the higher prices and protested A subsidy would have avoided this collateral damage Why wasn t a subsidy used Subsidy to an exporting industry Example Cotton The United States subsidizes cotton production In this industry however the US is major exporter 20 percent of global production 30 percent of global exports Because the US is so big in this market and because the subsidies are so large world prices are affected Subsidy to an exporting industry Cotton subsidies continued The government has guaranteed cotton rices to US producers regardless of global prices T e support price has been above world prices encouraging extra production Between 1999 and 2002 they received 20 billion Oxfam stud Every acre of cotton farmland in the US attracts a subsidy of 230 or around five times the transfer for cereals In 2 0102 farmers reaped a bumper harvest of subsidies amounting to 39 billion double the level in 1992 Subsidy to exporting industry Redistributive effects of cotton subsidies the largest 10 percent of cotton farms receive more than three quarters of total payments In 2001 ten farms between them received subsidies equivalent to 17 million Oxfam 2004 Estimates bythe International Cotton Advisory Committee ICAC using its World Textile Demand Model indicate that the withdrawal of American cotton subsidies would raise cotton prices by 11 cents per pound or by 26 percent The World Bank estimates that cotton producers in developing countries face annual losses of some 95 billion as a result of subsidies benefiting rich countries Some ofthe affected countries rely heaVIly on cotton earnings especially in Africa and South Asia Subsidy to exporting industry Cotton subsidies and dispute mediation at the WTO Brazil filed a complaint with the WTO arguin that the US was exceeding the target price it agreed to in 19 2 and that the subsidies depressed world prices In April 2004 the WTO found in favor of Brazil and ruled that the US should remove the subsidies within 6 months The US and the National Cotton Council objected The US Claim World prices are low because of growing supply elsewhere and falling demand with recession and a shift toward synthetic fibers The US filed an appeal in October that delayed the requirement that it comply but the WTO has recently March 2005 upheld the ruling The Dispute Settlement Body on 21 March 2005 adopted the Appellate Body andganel reports on the United States39 subsidies on upland cotton WT web site Job loss and import competition

foreign competition costs Not usually Firms typically either contract output or shut down depending upon expectations about the future and entryexit Trade policy with a domestic monopolist Suppose instead we had gone from autarky to trade with a quota Would the same procompetitive effect have obtained A quota and a domestic monopolist WWW N P P quam PW I M AC PW R total domestic demand I W qum MR quota 1 Q The quota preserves in large measure the domestic producer s monopoly power It shifts his demand curve in some but leaves intact the downward slope and thus leaves intact the incentive to hold back production and drive up price 10 Domestic monopolies when imports are imperfect substitutes Implicitly we ve been assuming that monopolists produce a good that is a perfect substitute for imports But more tygically a domestic monopolist will produce an imperfectsu stitute Think of Renaut as a domestic monopolist in Honduras confronted with imported autos from Europe an the US When this the case the monopolist retains some market power in the face of trade even free trade To diagram this case we need to distinguish firmspecific demand from total demand for products in the monopolist s industry Trade and monopoly power when imports are imperfect substitutes Mc I l I I I free trade I I I I I I I I I I I I I I I I I I l Qmanky Q I Qrm Me Free trade drives down prices and output may contract too Exit may occur When would this happen 12 Summary of trade and monopoly In all the cases we have considered heightened import competition reduces prices for the domestic monopolist Whether the monopolist expands or contracts output depends upon how much market power it retains Qualitatively the results we have seen apply not just to monopolists but to domestic firms with market power in general Import competition may induce exit if their profits are squeezed too much If some firms exit what happens to output at the remaining firms Oligopoly and trade policy Sometimes several dominant producers are located in different countries Then it is possible that the trade policies of each producer s government can give it a strategic advantage in the global market for its good Example Widebody aircraft The United States has long complained that French and German subsidies to Airbus give that firm an unfair advantage The EU counters that military research funding and tax breaks from local governments amount to Boeing subsidies Oligopoly and trade policy In the past several years the dispute has heated up The EU has provided Airbus with development subsidies for its new A380 superjumbo meant to go head to head with Boeing s 747 The US has recently withdrawn from its 1992 accord with the EU limiting the form and extent of subsidies to civil aircraft producers On October 6 2004 the United States lodged a complaint against European plane development subsidies to Airbus with the VVTO triggering a titfortat European objection to indirect US subsidies for Boeing Earlier this week Europe and the United States moved closer to a VVTO showdown over plane subsidies after Airbus said it had received quotlegally bindingquot government funding pledges for its newly launched A350 jet program from France Germany Britain and Spain Oct 21 2005 Oligopoly and trade policy Most recently Airbus has be beset by problems of its own making Airbus and Boeing have been in a longrunning battle over aircraft orders a contest Airbus has been losing elsewhere but not in Russia because of production delays for its A350 jet NYT Nov 8 2006 Citing production delays dogging the Airbus doubledeck A380 airliner the FedEx Corporation canceled its order for 10 cargo versions of the huge aircraft and in their place ordered 15 Boeing 777 freighters and took options on 15 more NYT Nov l l 2006 Oligopoly and trade policy But the trade dispute continues The United States on Wednesday filed an updated complaint with the World Trade Organization against European government spending on Airbus warning that the plane maker would break international rules if it accepted launch aid to build the new wide body A350 lnt l Herald Tribune Nov 15 2006 The negotiation remains snagged on the definition of state aid that is not allowed under WTO rules Boeing39s position is that the only major issue to be settled is launch aid under which it argues Airbus has received substantial amounts of state aid to develop new aircraft That aid must then be repaid when the aircraft begins selling The EU maintains that Boeing receives its own US government aid through military contracts and tax breaks given by local jurisdictions like Boeing Aircraft39s headquarters city Seattle Boeing rejects those charges and so far has refused to treat them as a tradeoff for launch aid in the negotiations

encouraged to supply more by the subsidy and Airbus s optimal reaction to the reduction in demand for nonBoeing airplanes is to reduce y We end up with a new equilibrium at which the home firm has gained market share and the foreign firm has lost Oligopoly and trade policy effects of a subsidy More generally the effects of a subsidy are the following Production shifts away from foreign supplier toward the home supplier Price decreases because the reduction abroad is less than the increase at home The slope ofthe foreign reaction function would have to l in order for the two adjustments to be offsetting but it is in fact 2 Oligopoly and trade policy effects of a subsidy Surplus changes for all agents involved Consumers are better off because they face a lower price The us government has spent some money on the subsidy Some profits have been shifted from the foreign producer to the home producer If there had been scale economies this would have created additional benefits for the home

progress and factor prices Now consider a country that has technological progress concentrated in its skillintensive goods Highskill workers gain and lowskill workers lose Why The HO model Technological progress and factor prices This scenario is consistent with the rising wage gap But is it consistent with other facts Ifthe technological progress is global we should see the same pattern everywhere But this should drive down relative prices of the skillintensive goods offsetting the productivity effect on wages Perhaps global demand for skillintensive goods is growing too Another puzzle this scenario implies that the skillintensity of production should be falling In fact it has been rising We need a change in the shape of the isoquants to do this The HO model
