Terms of trade movements and the global economic crisis

Dramatic changes in the relative prices of goods in international trade have accompanied, and indeed preceded, the recent global crisis. The causes and effects of the relative price changes are analysed by applying the analysis of business cycles developed by Joseph Schumpeter. Schumpeter’s analysis emphasises innovation and structural change (particularly creative destruction) which impart uneven development on the economy and can foster financial crises. This puts the current crisis in the context of long-wave development of the capitalist system and leads to predictions about the likely path of price and output changes over the next few decades.     

International treaties on trade and global pollution

The paper shows that global pollution need not rise under free trade in goods and/or emissions even in the complete absence of income effects. Differences in environmental concerns across the countries lead to differences in the pollution intensity of production and, thus, generate the possibility of increasing world output and income without increasing the world pollution by shifting the production of the polluting good from the country with higher pollution intensity of production to the country with lower one. We show that free trade in goods and/or emissions can induce precisely such a shifting of production with the country with greater environmental concern exporting the polluting good. The paper also demonstrates the possibility of a first-best international treaty on global pollution in which each country or group of countries is better-off.     

International trade and the negotiability of global climate change agreements

This paper examines the incentives for individual countries to engage in global negotiations to reduce carbon emissions in order to prevent global warming. To reduce carbon emissions a country reduces consumption of its own good. The direct effect of reducing its own consumption is that consumption declines and with it utility. However, reducing carbon emissions also lowers global temperatures and that increases utility. The trade-off between these two effects determines the incentive for countries to reduce carbon emissions. We find that larger countries are more likely to participate because a given percentage reduction in output will result in a larger reduction in global temperatures. Longer time horizons also lead to greater willingness to participate. The presence of international trade makes carbon reduction agreements more likely because reducing the output of your own (export) good has a positive terms of trade effect which reduces the cost of output reduction.     

Indivisibilities in the Ricardian model of trade

The idea that goods or factors of production may not be perfectly divisible has important implications for many areas of economics. This paper introduces both types of indivisibilities into the standard Ricardian model of international trade. Indivisibilities give rise to new results compared to the standard model with perfectly divisible goods and factors of production. Both types of indivisibility may result in complete specialisation even in autarky, while goods indivisibility may result in (ex ante) identical consumers consuming different bundles of goods, and hence enjoying different levels of welfare. Both types of indivisibilities lead to efficiency losses relative to the perfectly divisible case. International trade may eliminate efficiency losses resulting from indivisibility in the factors of production, but not those resulting from goods indivisibility. This suggests that the presence of indivisibilities leads to a second-best world, with the consequent implications for policy. The results of the paper are consistent with existing empirical evidence.     

Effects of global trade liberalization on softwood lumber markets

This study develops a world spatial equilibrium softwood lumber model comprised of the major importing and exporting countries/regions to analyse the impacts of global trade reform on the world softwood lumber market. The results show that free trade leads to an increase in lumber trade, and Canadian producers and US consumers are the biggest beneficiaries. Trade liberalization improves the overall world welfare as world producer and consumer surpluses increase. The result highlights the importance of moving towards free trade in the global softwood lumber market.     

Ethnic groups and the Heckscher-Ohlin-Samuelson trade model

Summary In this paper, we report a mode of the Harris-Todaro variety in which the labor force is composed of distinct and easily identifiable ethnic groups and in which capital is intersectorally mobile. We extend the central theorems of Heckscher-Ohlin-Samuelson trade theory to our model and also relate our results to other work.This work was conceived over several visits to The Pakistan Institute of Development Economics and finished at Berkeley where it was first presented at Professor Bardhan's Workshop in Development Economics. I am grateful to Professor Bardhan and to Director Naqvi and other Officers of the Institute for their hospitality and interest. I am also grateful to Naeem Siddiqui and Ray Reizman for several useful conversations; to S. Broca for many provocative comments on the HOS trade model; and, in particular, to one of three anonymous referees for her/his careful reading and detailed comments.     

Foreign trade model of the centrally planned economies

This paper presents a linked econometric model of the foreign trade of seven European socialist countries grouped in the Council of Mutual Economic Assistance (CMEA). The model aims at analysing the role of the international and regional trade in the economies of the socialist countries. The central part of the model is formed by foreign trade equations which allow analysis of the economic processes of the CMEA countries in relationships with the intra-CMEA and international trade. The assumptions of the model structure and some empirical results are discussed.

International differences in emissions intensity and emissions content of global trade

Understanding international differences in the emissions intensity of trade and production is essential to understanding the effects of greenhouse gas limitation policies. We develop data on emissions from 41 industrial sectors in 39 countries and estimate the CO₂ emissions intensity of production and trade. We find no evidence that developing countries specialize in emissions-intensive sectors; instead, our evidence suggests that emissions intensities differ systematically across countries because of differences in production techniques. Our results confirm that international differences in emissions intensity are substantial, but suggest that they do not play a significant factor in determining patterns of trade.     

Revisiting the effects of regional trade agreements on trade flows with proper specification of the gravity model

This paper uses a gravity model to assess ex-post regional trade agreements. The model includes 130 countries and is estimated with panel data over the period 1962-1996. The introduction of the correct number of dummy variables allows for identification of Vinerian trade creation and trade diversion effects, while the estimation method takes into account the unobservable characteristics of each pairs of trade partner countries, the endogeneity of some of the explanatory variables as well as a potential selection bias. In contrast to previous estimates, results show that regional agreements have generated a significant increase in trade between members, often at the expense of the rest of the world.     

Dynamic response of bank-intermediated trade finance to a global liquidity shock

This paper investigates the bank-level responses of a bank-intermediated instrument of trade finance to a negative global liquidity shock in Korea. Using a factor-augmented vector autoregression approach, the results show that there exists significant heterogeneity in bank-level trade-finance responses to a global liquidity shock. In addition, we find that the source of the heterogeneity is the bank-level foreign currency liquidity condition; banks with a better foreign currency liquidity condition may dampen the negative impact of a global liquidity shock on trade-finance.     

A dynamic model of endogenous trade policy

Empirical evidence suggests that past levels of protection are significant determinants of current levels of protection. We investigate dynamic interactions among interest groups and resulting endogenous links between current and future trade policies. We explore these intertemporal links in a small open economy in which lobbying and tariff policies are the outcome of a dynamic game among factor owners. The model can generate cycles with prolonged periods of free trade and/or prolonged periods of restricted trade (i.e., persistent trade policies). An interesting aspect of the environment is the role of lobbying as a partial substitute for intertemporal trade. JEL Classification: F13, C73
Un modèle dynamique de politique commerciale endogène. Les résultats d'analyses empiriques montrent que les niveaux passés de protection sont des facteurs importants dans l'explication des niveaux de protection actuels. Ce mémoire analyse les interactions dynamiques entre groupes d'intérêt et les liens endogènes qui en résultent entre les politiques commerciales présentes et futures. On explore ces liens intertemporels dans une petite économie ouverte où lobbying et politiques tarifaires sont le résultat d'un jeu dynamique entre les propriétaires des facteurs de production. Le modèle peut engendrer des cycles où on observe des périodes prolongées de libre commerce et/ou des périodes prolongées de commerce restreint (i.e. des politiques commerciales persistantes). Il appert que le rôle du lobbying est un substitut partiel pour le commerce intertemporel.     

Foreign direct investment and international trade in a continuum Ricardian trade model

We develop a continuum Ricardian trade model to capture both North–South trade and technology transfer via foreign direct investment (FDI) by multinational enterprises (MNEs). We show that there is a unique range of products produced in the South by MNEs. In the case of an infinitely elastic supply of expatriates, if the ability of Southern workers in absorbing Northern technology increases, then (a) the range of MNE production increases, (b) Northern workers's welfare and Southern workers' welfare change in opposite directions, and (c) the world aggregate welfare increases under certain conditions. We explore issues such as North–South wage gaps, FDI policies and the product cycle. We also derive results under a general supply of expatriates.     

Peak globalization: Climate change, oil depletion and global trade

The global trade in goods depends upon reliable, inexpensive transportation of freight along complex and long-distance supply chains. Global warming and peak oil undermine globalization by their effects on both transportation costs and the reliable movement of freight. Countering the current geographic pattern of comparative advantage with higher transportation costs, climate change and peak oil will thus result in peak globalization, after which the volume of exports will decline as measured by ton-miles of freight. Policies designed to mitigate climate change and peak oil are very unlikely to change this result due to their late implementation, contradictory effects and insufficient magnitude. The implication is that supply chains will become shorter for most products and that production of goods will be located closer to where they are consumed.     

A model of trade and growth for the developing world

This paper describes structure, assumptions and projection results of the SIMLINK model. The purpose of this modelistosimulate the trade linkages between the developed and developing world. By taking the growth expectations of the OECD countries and the price of petroleum as a starting point, the model estimates the price and volume of a series of commodities important in LDC exports. The export earnings for seven LDC regions are estimated from the commodity projections, and combined with a predetermined estimate of capital inflows to calculate import capacity. A simple growth model for each region then determines the import constrained growth rate for that region.
