State Trading Enterprises as an Impediment to Improved Market Access: The Case of the Korean Rice Market

The trade and welfare effects of tariffs are well known. Less well known, and more difficult to analyze, are the economic effects of state trading enterprises (STEs). Despite STEs in importing countries having the potential to limit market access, they are no longer on the agriculture agenda in the Doha Round Negotiations in the WTO, because some Members have asserted that importing STEs do not distort international trade. We evaluate this assertion through the use of a theoretical model of an STE, which is calibrated to data for the Korean rice market. We show that this STE does distort international trade by restricting market access relative to a Cournot benchmark, and that it affects the domestic and international distribution of social welfare. This finding permits the conclusion that an important opportunity is being missed in the negotiations to improve market access, because importing STEs are not on the agenda.     

Managerial capital,occupational choice and inequality in a global economy

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice and income inequality. Individuals with different managerial talent choose to become entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial capital. The model generates three income classes: low‐income workers facing the prospect of unemployment, middle‐income entrepreneurs managing domestic firms and high‐income entrepreneurs managing global firms. Trade liberalization policies raise unemployment and improve welfare. A reduction in per‐unit trade costs raises top incomes and generates labour‐market polarization. A reduction in fixed exporting costs has an ambiguous effect on top incomes and personal income distribution. Policies reducing labour‐market frictions or the costs of managerial‐capital acquisition create more jobs and improve welfare. The income distributional effects of labour‐market policies depend on which policy is implemented.     

Labour Markets and Flexibility in the 1990s: The Europe-USA opposition revisited

Economists' contest on labour market flexibility has quickly pivoted around the stylised trade off between more flexibility and growth on the one hand and increased inequality of income on the other, the welfare implications of this trade off being too often assumed rather than verified. This article uses the essays collected in the Special Issue on Labour Markets and Flexibility in the 1990s of the International Review of Applied Economics to challenge the terms of this trade off as well as the related welfare assumptions. Some of the most popular tenets in the literature are assessed in the light of the evidence and the arguments put forward by the authors contributing to the Special Issue, in particular, the notion that the European labour market is rigid, the contention that more flexibility is imposed by international competition, or that labour market regulation weakens both employment and output growth, the belief that the main welfare cost of flexibility is increased inequality of earnings or the fear that flexibility may be primarily 'female'.     

Beyond the income effect of international trade on ethnic wars in Africa

We use detailed information on the location of agricultural and mining production to approximate international trade for different ethnic groups in order to study its impact on ethnic conflicts in Africa between 1993 and 2010. The goal is to go beyond the income effects of trade to study the residual effects of globalization on conflicts. We find that once we control for income but also for a wide variety of different factors in conflicts (using political variables and fixed effects), the international trade by ethnic groups has a pacific impact on conflicts. While this peaceful impact of trade is mainly found in the trade in agricultural products, it does not have a significant impact on the international trade in mining products. Finally, we propose an original two-step analysis showing that exports significantly reduce conflicts by affecting time-varying national characteristics. We interpret this result as an indication that globalization in Africa has participated in the formation of new national identities with peaceful effects between ethnic groups.     

INCOME DISPERSION AND PRICE DISCRIMINATION

Abstract.  This paper analyses the effects of inter-market and intra-market income heterogeneities on output and social welfare under uniform pricing and differential pricing regimes by considering a finite number of markets. We first derive the linear demand curve in each market under plausible conditions, and then show that more markets (and consumers) are excluded under uniform pricing the higher are the inter-market income differences. We also show that adding markets, even of lower income levels than those of existing markets, helps to decrease prices and thus cause more markets to be served. Implications of intra-market income dispersion are also explored.     

Trade,GMOs and Environmental Risk: Are Current Policies Likely to Improve Welfare?

Food with inputs from genetically modified organisms (GMOs) has met considerable skepticism among European Union (EU) consumers. The EU import ban on GM food has triggered a great deal of controversy and has been partly replaced by a mandatory labeling scheme. Although there is no measure in the General Agreement on Tariffs and Trade that directly addresses the use of product labeling, WTO and others have been skeptical to mandatory product labeling on the grounds that they may be used as hidden protectionism hampering global welfare. This study has two foci. First, we examine how different policies for the production and use of GMOs might influence the market outcome in consumer food markets. Second, we evaluate the welfare effects of the policy measures. We find that mandatory labeling often increases domestic welfare and, may also enhance global welfare. On the other hand, a trade ban is more likely to decrease global welfare.     

Cross-Border Mergers as Instruments of Comparative Advantage

A two-country model of oligopoly in general equilibrium is used to show how changes in market structure accompany the process of trade and capital-market liberalization. The model predicts that bilateral mergers in which low-cost firms buy out higher-cost foreign rivals are profitable under Cournot competition. As a result, trade liberalization can trigger international merger waves, in the process encouraging countries to specialize and trade more in accordance with comparative advantage. With symmetric countries, welfare is likely to rise, though the distribution of income always shifts towards profits.     

North–South trade and income inequality

This paper investigates the effects of North–South trade on international income inequality. While empirical studies suggest that trade liberalization encourages income convergence and reduces the per capita income gap between poor and rich countries, North–South trade is shown to increase the income gap between the two regions. On the other hand, trade liberalization by either region increases the welfare of both regions, and does not necessarily reduce the gap in “real income” or utility.     

International finance in general equilibrium

Our purpose in this paper is to unify international trade and finance in a single general equilibrium model. Our model is rich enough to include multiple commodities (including traded and nontraded goods), heterogeneous consumers in each country, multiple time periods, multiple credit markets, and multiple currencies. Yet our model is simple enough to be effectively computable. We explicitly calculate the financial and real effects of changes in tariffs, productivity, and preferences, as well as the effects of monetary and fiscal policy.We maintain agent optimization, rational expectations, and market clearing (i.e. perfect competition with flexible prices) throughout. But because of the important role money plays, and because of the heterogeneity of markets and agents, we find that fiscal and monetary policy both have real effects. The effects of policy on real income, long-term interest rates, and exchange rates are qualitatively identical to those suggested in Mundell-Fleming (without the small country hypothesis), although our equilibrating mechanisms are different. However, because the Mundell-Fleming model ignores expectations and relative price changes, our model predicts different effects on the flow of capital, the balance of trade, and real exchange rates in some circumstances.     

Innovation and international trade in technology

The international market for technology is growing rapidly relative to world GDP. To study the international technology market, I present a model of innovation and international trade in which inventors auction their technology in both domestic and foreign markets. There is monopolistic competition in differentiated products. International trade in technology has number of significant economic effects. Technology trade improves the quality of innovation by increasing the pool of R&D experiments from which the best technology is chosen. Technology trade increases the efficiency of invention while at the same time lowering the total number of inventors relative to the equilibrium without technology trade. Technology trade increases the volume of trade in goods. Technology trade increases product variety at the market equilibrium. Technology trade increases national income in each country and increases total gains from trade.     

Infrastructure,Multinational Affiliate Production,and the Pattern of Trade

In a two-country general equilibrium model with endogenously determined domestic and multinational firms, it is shown that public infrastructure development can have diverging implications for horizontal multinational affiliate firm production and trade, depending on the type of infrastructure invested in. Infrastructure investments with strong productive or local transport effects (i.e. schools or local roads) lead to greater domestic firm production and exports, fewer imports, and more foreign multinational affiliate firm production in the country making the investment. On the other hand, infrastructure projects that lower international trade and transaction costs (i.e. shipping ports or airports) lead to more domestic firms in both countries, a greater volume of bilateral exports in both directions, and less multinational affiliate production. Further, the effect of different types of infrastructure investment on income and welfare of the open economies is explored.     

Does Preferential Trade Benefit Poor Countries? A General Equilibrium Assessment with Nonhomothetic Preferences

We develop a Ricardian model of trade with nonhomothetic preferences to analyze preferential trade agreements (PTAs) among countries of different stages of economic development. The richer a country is, the more likely will PTAs improve its terms of trade, also when it is a non‐member. Rich non‐member countries are also less likely to incur welfare losses from PTAs. PTA membership only guarantees welfare gains for countries that are too poor to import the goods rich countries produce. For all other countries, the welfare effects of joining PTAs depend on the world income distribution and on the strength of comparative advantages.     

Welfare Effects of Foreign Direct Investment: Cost Saving vs. Signaling

We compare the effects of two types of foreign direct investment (FDI) (viz., FDI for trade cost saving and FDI for signaling foreign cost of production) on consumer surplus, profit of the host-country firm and host-country welfare. We show that the effects are dramatically different. If the reason for FDI is to save trade cost, FDI (compared to export) always makes the consumers better off and the host-country producer worse off, while the effect on host-country welfare is ambiguous. However, if the FDI is to signal the foreign cost of production, FDI (compared to export) always makes the host-country producer better off and increases host-country welfare, while it makes the consumers almost always worse off.     

The Economic Efficiency of Policy Reform and Partial Market Liberalization under Transaction Costs

The article presents an integrated analysis of the effects of domestic and trade policy reform on resource allocation and welfare under transaction costs. It develops a general multiagent, multicommodity model, where transaction costs are the costs of resources used in the exchange process. The influence of domestic and trade policy (including both price and quantity instruments) on distorted market equilibrium is analysed. Alternative concepts of distorted equilibrium are presented and investigated. They provide a basis for evaluating the effects of multilateral partial market liberalization on resource allocation and welfare under transaction costs. New conditions are derived under which multilateral policy reforms generate Pareto improvements.

Outsiders in economic integrationThe case of a transition economy

We use a spatial model of endogenous growth to investigate the likely impact of discriminatory integration between two advanced insider countries on their own welfare as well as on the welfare of an outsider transition economy. A first point is that, since convergence in per capita income levels depends on relative market access and local market size, piece-wise integration causes insider-outsider divergence. Nonetheless, outsiders can gain in absolute terms if integration fosters the global growth rate. We also show that exclusion from a regional agreement and on-going transition have unpredictable joint effects on the structural adjustment, which might even exhibit a swinging behaviour. Such swings may imply large adjustment costs, which can be reduced by careful integration design. With this respect, the asymmetric phasing-out of trade barriers built into the Europe Agreements seems to work in the right direction. Finally, we point out that the predictions of the model in terms of direct investment and terms-of-trade dynamics are broadly consistent with some actual developments in transition economies.     

Comparing Tax and Tax Reallocation Payments in Financing Rail Noise Abatement Programmes: Results from a Stated Choice Valuation Study in Italy

The paper examines the use of stated choice experiments (SC) to assess the economic value of alternative rail noise reduction interventions on the Brennero railway in Italy. The paper formally tests the econometric robustness of the SC estimates under three payment regimes: (a) a regional tax, where consumers must trade off welfare gains due to noise reduction for part of their income; (b) a transport tax reallocation scheme, where consumers must trade off a part of the tax payments that are currently spent on the public transport sector; and (c) an administration tax reallocation scheme, where consumers must trade off a part of the tax payments that are currently spent on the administration sector. The test results are varied. On the one hand, the SC estimates are found to be statistically different for the tax reallocation and the tax introduction regimes. This confirms previous valuation research results, and thus reiterates the hypothesis that states the inequality between marginal values of private income and public money. On the other hand, the SC estimates are not found to be statistically different for the two proposed tax reallocation regimes, suggesting that, in the case study investigated here, the marginal value of public money does not depend upon the budget source.     

International trade and “Catching up with the Joneses”: Are the consumption patterns convergent?

We use a dynamic international trade model to analyse the implications of international trade for agents’ preferences and economic growth. This model is based on the home market effect with external habit formation (“catching up with the Joneses”) and “learning by doing” in production. We demonstrate the following: the historical composition of consumption in countries determines industrialization after trade; the preferences of agents converge after trade, independent of the economic results; and the welfare effects of trade may be positive or negative depending on trading partner characteristics. In some scenarios, autarky is strictly preferred to trade. Thus, international trade does not necessarily imply greater welfare, as is the typical result in a static context under CES preferences.     

Asset Markets and Endogenous Liquidity

In financial markets characterized by imperfect depth, speculative trading will have transitory effects on the market price as market makers must be compensated for the risk of holding the asset. The number of people providing liquidity to a market will generally be endogenously determined by the quantity of liquidity demanded. This paper looks for evidence of endogenous liquidity provision in several international stock and bond markets. Evidence shows strong support for these speculative dynamics in the stock markets. The evidence for these dynamics is less striking with fixed‐income prices, consistent with the less speculative nature of these markets.     

POVERTY DYNAMICS DURING TRADE REFORM: EVIDENCE FROM RURAL VIETNAM

This paper implements and adapts the conceptual framework developed by Winters (2002) that identifies the transmission mechanisms between trade policy reform and household welfare outcomes. We make use of household panel data from Vietnam collected in two years, 1992–93 and 1997–98 that span the very earliest years of the reform period and its immediate after effects. Poverty dynamics are modeled using changes in consumption expenditure and poverty transition models. The trade effect is captured by a set of variables that are most likely to have an impact on rural poverty, namely prices of staples and employment in the export sector. We show that trade liberalization has a material and positive effect on rural household welfare and this trade effect is largely transmitted to the poor through the labor market channel.
