Smith's argument for free trade International Trade & the World Economy; Charles van Marrewijk Smith's argument for free trade You do not make your own clothes or shoes but buy them from your tailor or shoemaker to enjoy the benefits of increased specialization. You concentrate on producing what you do best. International trade, similarly, allows countries to concentrate on producing what they do best.

Analysis of absolute cost advantage International Trade & the World Economy; Charles van Marrewijk Analysis of absolute cost advantage Ch. 2 tool: productivity table to summarize the state of technology Note that the USA is more efficient than Japan for the production of Food (requires 2 < 3 laborers), while Japan is more efficient than the USA in the production of cars (requires 6 < 8 laborers). In autarky (without international trade) both countries will produce both goods if consumers demand both Food and Cars.
Analysis of absolute cost advantage International Trade & the World Economy; Charles van Marrewijk Analysis of absolute cost advantage According to Adam Smith, both countries can gain from international trade through specialization (USA producing more food and Japan producing more cars): Suppose the USA produces 1 car less, this frees up 8 laborers. These 8 laborers can now produce 8/2 = 4 units of food To keep the production level of cars constant, Japan should make 1 car more. This requires 6 laborers. These 6 laborers could have made 6/3 = 2 units of food. Conclusion: USA Japan change world prod. production of cars: -1 +1 0 production of food: +4 -2 +2 The extra production represents gains from trade

Classical economics and comparative advantage International Trade & the World Economy; Charles van Marrewijk Classical economics and comparative advantage Technological differences between nations are the classical driving force behind international trade flows. According to David Ricardo relative or comparative differences are important, not absolute differences. According to Paul Samuelson (1915-; Nobel prize 1970) the theory of comparative advantage is One of the few ideas in economics that is true without being obvious The idea of comparative advantage is often misunderstood, see Paul Krugman (1953-) “Ricardo’s difficult idea” at http://web.mit.edu/krugman/www

Analysis of comparative advantage International Trade & the World Economy; Charles van Marrewijk Analysis of comparative advantage Productivity table to summarize the state of technology Note that the EU is more efficient than Kenya in the production of both goods, requiring 2 < 4 laborers for Food and 8 < 24 laborers for Chemicals. Why would the EU trade with Kenya? Note: EU is twice more productive in Food, and three times in Chem. In autarky (without international trade) both countries will produce both goods if consumers demand both Food and Chemicals.
Analysis of comparative advantage International Trade & the World Economy; Charles van Marrewijk Analysis of comparative advantage According to David Ricardo both countries can gain from international trade through specialization (EU producing more chemicals and Kenya producing more food): Suppose Kenya produces 1 chemical less, this frees up 24 laborers. These 24 laborers can now produce 24/4 = 6 units of food To keep the production level of chemicals constant, the EU should make 1 chemical more. This requires 8 laborers. These 8 laborers could have made 8/2 = 4 units of food. Conclusion: EU Kenya change world prod. production of chem. +1 -1 0 production of food -4 +6 +2 The extra production represents gains from trade

similar trade policy access to the Japanese for all countries International Trade & the World Economy; Charles van Marrewijk The Balassa index II The Ottens (2000) calculations of the Balassa index uses the OECD countries as reference. Sometimes all countries in the world are used. Hinloopen and van Marrewijk (2001) use data on EU exports for 98 sectors to Japan to calculate the Balassa index, such that: similar trade policy access to the Japanese for all countries similar development levels for the EU countries similar distance (physical and pecuniary costs) for all countries which supposedly results in a ‘cleaner’ measure of comparative advantage and the probability density function of the Balassa index as depicted on the next slide.

International Trade & the World Economy; Charles van Marrewijk Conclusions Technological differences between countries are the classical driving force for international trade flows. Only comparative costs, not absolute costs, are important for determining the direction of trade flows. Absolute costs are important for determining a country’s welfare level. Empirically, comparative costs performs somewhat better than absolute costs. Allowing for more countries and more goods is easy, allowing for more than one factor of production is not (see part II).

Factor price equalization (FPE) International Trade & the World Economy; Charles van Marrewijk Factor price equalization (FPE) In a neo-classical framework with 2 final goods and 2 factors of production, there is a one-to-one correspondence between the prices of the final goods and the prices of the factors of production, provided both goods are produced. This implies: factor rewards known derive prices of final goods prices of final goods known derive factor rewards Corollary In a neo-classical framework with 2 countries, 2 final goods, and 2 factors of production, international trade of the final goods, which equalizes the prices of these goods in the two nations, also leads to an equalization of the rewards of the factors of production in the two nations, provided both final goods are produced in both nations and the state of technology in the two nations is the same.

So if e.g. the production of manufactures is capital intensive and the price of manufactures rises: the rental rate rises and the wage rate falls.

Given the wage-rental ratio, cost-minimization determines the optimal capital-labor ratio for production of food and manufactures. Expansion and contraction of production for food and manufactures does not affect the optimal capital labor ratio (straight lines) The distribution of capital and labor is then determined by the full employment conditions (all capital and labor should be used), that is the point of intersection of the expansion paths in the Edgeworth Box

Heckscher-Ohlin proposition International Trade & the World Economy; Charles van Marrewijk Heckscher - Ohlin Heckscher-Ohlin proposition In a neo-classical framework with 2 final goods, 2 factors of production, and 2 countries which have identical homothetic tastes, a country will export the good which intensively uses the relatively abundant factor of production. If the production of manufactures is capital intensive and Austria is capital abundant, Austria will export manufactures and import food.

Maximizing the utility function International Trade & the World Economy; Charles van Marrewijk Demand All previous neo-classical results depend only on the supply side, since we have to specify the demand side to make conclusions about trade flows. Maximizing the utility function subject to a standard budget contraint implies that consumers will spent a fraction of their income on manufactures (quite similar to cost minimization problem for producers)

The case of the missing trade International Trade & the World Economy; Charles van Marrewijk The case of the missing trade First important empirical study (1956) leads to ‘Leontief paradox’: supposedly capital abundant USA imports capital intensive goods? Possible explanations: demand bias, factor-intensity reversal, restrictiveness of 22 2 framework. Later studies, e.g. Bowen, Leamer, and Sveikauskas (1987), analyze more goods, more factors, more countries, as did Trefler (1995) who finds modest support for neo-classical trade model (about 71%) shows that factor service trade is smaller than factor endowments prediction (case of missing trade) support increases if technological differences (part I of the book) are taken into consideration (to about 78%) support increases if domestic demand bias is taken into consideration (to about 87%) with neo-classical model, different technology, and demand bias about 93% of international trade flows can be explained.

International Trade & the World Economy; Charles van Marrewijk Reciprocal dumping Cournot competition model with 2 identical countries and positive (iceberg) transport costs; trade results in ‘cross-hauling’ / ‘reciprocal dumping’: product sold at lower mark-up abroad than at home. Producers accept lower mark-up abroad because of perceived higher elasticity of demand (lower market share) Despite ‘pointless and costly’ two way trade welfare increases if the transport costs are not too high as a result of the pro-competitive gains from trade.

Application: the Twaron takeover International Trade & the World Economy; Charles van Marrewijk Application: the Twaron takeover An example of pro-competitive gains from trade in reverse: the Twaron (Dutch firm) takeover by Teijin (Japanese firm) reduces the number of competitors in the aramid fiber market (used for friction, sealing, bullet proof vests, etc.) from 3 to 2 (other competitor is DuPont). Depending on price elasticity this raises the market price and the profit level for the remaining firms.

Optimal pricing and zero profits International Trade & the World Economy; Charles van Marrewijk Optimal pricing and zero profits As a result of IRS each variety is produced by single producer. This producer has market power and charges a monopolistically competitive price (determines the optimal price by MR = MC, taking the prices charged by the other firms [the price index P] as given). Because the price elasticity of demand is constant (equal to the parameter ) the mark-up over marginal costs charged by the producer is also constant. Firms will enter the market (producing new varieties) if profits are positive; they will exit if profits are negative. The number of varieties N produced is therefore determined by the zero-profit condition. In the Dixit-Stiglitz model the number of varieties N produced is proportional to the size of the economy as measured by the labor force

Intra-industry trade is measured using the Grubel-Lloyd index. International Trade & the World Economy; Charles van Marrewijk Conclusions Empirically observed prevalence of intra-industry trade (two-way trade in similar products) puzzled theorists. Intra-industry trade is measured using the Grubel-Lloyd index. Krugman uses Dixit-Stiglitz variety approach with monopolistic competition and IRS to explain intra-industry trade. Trade extends the market and raises welfare through an increases of the number of varieties available (love-of-variety). Alternative interpretation (Ethier) explains intra-industry trade through exchange of intermediate goods; increased specialization leads to positive production externalities.

Evaluation of strategic trade policy International Trade & the World Economy; Charles van Marrewijk Evaluation of strategic trade policy Strategic trade policy seems to give an intellectual motivation for government interaction in the trade system to benefit the domestic economy. There are, however, several important reservations: Competition for resources; in general equilibrium the expansion of the protected sector comes at the cost of another sector where those resources might have been used more effectively. Entry and exit of firms; will erode supernormal profits. Retaliation; will result in a trade war. Informational requirements (regarding nature of competition, cost structure, demand, strategic interaction, etc.); most important argument, since these are clearly beyond the control of any government in the world.

International Trade & the World Economy; Charles van Marrewijk Conclusions With imperfect competition tariffs and quota’s are no longer equivalent. Tariffs are less restrictive than quota’s as tariffs leave the forces of foreign competition intact. Strategic trade policy: provide competitive advantage to domestic firms by providing a credible pre-commitment in competition game. Nature of optimal strategic trade policy very sensitive to type of competition and dynamic structure of competitive game model. Also other weaknesses in strategic trade policy arguments (competition for resources, entry & exit, retaliation, information)

OECD is organization of economically more advanced countries. International Trade & the World Economy; Charles van Marrewijk Conclusions GATT, replaced by WTO, deals most directly with international trade problems (GATT rounds to reduce trade barriers become more complicated, take longer and involve more countries over the years). UN organizations affect all aspects of human life; UNCTAD focuses on problems of developing countries. OECD is organization of economically more advanced countries. Adjusting a country’s organizational and institutional framework is an enormous and time-consuming process, as illustrated by the Central and Eastern European countries.

There are many regional trade agreements (RTAs) in the world. International Trade & the World Economy; Charles van Marrewijk Conclusions There are many regional trade agreements (RTAs) in the world. We also distinguish FTAs, customs union, common market, economic union. RTAs in general increase welfare through trade creation, but the discriminatory nature of an RTA may make the net welfare effect negative. Increased popularity of Regionalism rather than Multilateralism may be bad for the world economy. EU is most succesful and powerful economic integration scheme; many CEE countries want to join; EU’s political decision process needs to be revised.

Distinction stable equilibrium and unstable equilibrium. International Trade & the World Economy; Charles van Marrewijk Conclusions Combining various international economic theories with factor mobility provides a simple theory of location and agglomeration. Distinction short-run equilibrium (given distribution of the manufacturing labour force) and long-run equilibrium (endogenously determined by equality of real wages). Distinction stable equilibrium and unstable equilibrium. Using computer simulations: high transport costs lead to spreading of economic activity low transport costs lead to agglomeration of economic activity intermediate transport costs lead to multiple long-run equilibria Extensions of the basic model can explain empirical regularities, such as Zipf’s Law and the Gravity Equation.

Kaldor's stylized facts of economic growth International Trade & the World Economy; Charles van Marrewijk Kaldor's stylized facts of economic growth Nicholas Kaldor (1961) suggested the following list of stylized facts: The continued growth in the aggregate volume of production and in the productivity of labor at a steady trend rate. A continued increase in the amount of capital per worker. A steady rate of profit on capital. Steady capital-output ratios over long periods. A steady investment coefficient, and a steady share of profits and wages.

Paul Romer’s (1994) list of stylized facts: International Trade & the World Economy; Charles van Marrewijk Endogenous growth Paul Romer’s (1994) list of stylized facts: There are many firms in a market economy. Discoveries differ from other inputs in that many people can use them at the same time (nonrival goods). It is possible to replicate physical activities. Technological advance comes from things that people do. Many individuals and firms have market power and earn monopoly rents on discoveries.

Rising per capita income is relatively new phenomenon. International Trade & the World Economy; Charles van Marrewijk Conclusions Rising per capita income is relatively new phenomenon. Some countries have experienced relatively steady growth, others long periods of stagnation and rapid increases. Neo-classical model based on capital accumulation needs exogenous technological change to ‘explain’ growth; large Solow residual. Endogenous growth models based on imperfect competition and innovation (new goods and/or quality improvements) led by entrepreneurs in search of profits. Large swings in economic prosperity may be explained by geographical economics model.

International Trade & the World Economy; Charles van Marrewijk Conclusions Applied trade policy uses model structure determined by current data with detailed policy orientation analyzing non-local changes. For questions limited in scope: applied partial equilibrium (Harberger triangles). More ambitious questions: AGE models; (i) CRS and perfect competition, (ii) IRS and imperfect competition, (iii) dynamic. International contacts (trade, fdi, etc.) spread ideas, new goods and services, etc. Barriers to trade limit the spread of ideas, thus leading to products not introduced; potential dynamic costs are large, as measured by the Dupuit triangles.
