Endogenous tariffs and trade adjustment assistance

This paper examines whether trade adjustment assistance is an effective tool for blunting political opposition to trade liberalization. The traditional argument is that adjustment assistance bribes labor unions so that they will accept reduced tariff protection. In this way, a trade adjustment assistance program should help the government lower tariffs and increase social welfare. This paper introduces trade adjustment assistance into a political economy model of endogenous tariff formation. The model shows that adjustment assistance reduces policy makers’ incentives to press for trade liberalization and may slow down the pace of reform and lower social welfare under certain plausible conditions.     

Time structure of production and the theory of international trade

This paper reexamines aspects of international trade theory by taking account of the time required for transforming inputs into outputs. The discussion focuses explicitly upon the time structure of production, characterized by profiles of inputs and outputs over time. Each of the model's two consumer-good sectors has different flow-input flow-output technology, with which labor produces heterogeneous capital goods and final output. As shown by the analysis, intersectoral differences in the time structure of production have important implications for the impact of world trade on a country's employment of labor, accumulation of capital and level of income.     

A theory of the currency denomination of international trade

The currency denomination of international trade has significant macroeconomic and policy implications. In this paper we solve for the optimal invoicing choice by integrating this microeconomic decision at the level of the firm into a general equilibrium open economy model. Strategic interactions between firms play a critical role. We find that the less competition firms face in foreign markets, as reflected in market share and product differentiation, the more likely they will price in their own currency. We also show that when a set of countries forms a monetary union, the new currency is likely to be used more extensively in trade than the sum of the currencies it replaces.     

Customs union theory and the nonuniformity of tariffs

Allowance is made for the initial nonuniformity of the tariffs of a union country before it joins a customs union. The reduction of such nonuniformity is a possible source of welfare again distinct from the usual trade creation and trade diversion effects. A net welfare gain from a union may result even when the country's total trade stays unchanged and even when all trade with the outsider ceases. A three-product, small-country model is used, domestic production and consumption substitution between the two importables yielding the import pattern effect that produces the possible gains referred to.     

浅谈技术性贸易壁垒与中国的国际贸易

在经济全球化，国际贸易日趋激烈化的趋势下，科技日新月异，同时也随之产生了国际贸易中的又一重要手段一技术性贸易壁垒(Technical Barriers to Trade—TBT)。所谓技术性贸易壁垒，是指一国以维护国家安全，或保护人类健康和安全，保护动植物的生命和健康，保护生念环境，或防止欺诈行为，保证产品质量为由，采取一些强制性或非强制性的技术性措施，这     

The asymmetric effects of tariffs on intra-firm trade and offshoring decisions

This paper studies the effects of tariffs on intra-firm trade. Building on the Antràs and Helpman (2004) North–South theoretical framework, I show that higher Northern tariffs reduce the incentives for outsourcing and offshoring, while higher Southern tariffs have the opposite effects. I also show that increased offshoring and outsourcing imply a decrease in the ratio of Northern intra-firm imports to total imports, an empirically testable prediction. Using a highly disaggregated dataset of U.S. (the North) imports and relevant U.S. and foreign tariffs, I find robust evidence to support the model's predictions.     

Variable labour supply and the pure theory of international trade : An empirical note

Previous writers have shown that variable labour supply may lead to perverse price output responses in the two-sector Heckscher-Ohlin model. This note attempts to assess the empirical likelihood, as opposed to the theoretical possibility, of such perversities. Using a range of plausible parameter values, we conclude that cases of a perverse price-output response consistent with dynamic stability of the model, though theoretically possible, are unlikely to arise in practice.

Increasing returns,monopolistic competition,and international trade

This paper develops a simple, general equilibrium model of noncomparative advantage trade. Trade is driven by economies of scale, which are internal to firms. Because of the scale economies, markets are imperfectly competitive. Nonetheless, one can show that trade, and gains from trade, will occur, even between countries with identical tastes, technology, and factor endowments.     

Entrepreneurial ability, income distribution, and international trade

This paper develops a two-sector model in which the firms in one sector are heterogeneous due to differences in the level of ability between entrepreneurs. Changes in prices lead to entry or exit of marginal firms and changes in the size of infra-marginal firms. The effects of endowment changes and output price changes are shown to depend on factor intensities of marginal and infra-marginal firms. Conflicts between entrepreneurs may arise over commercial policies if factor intensities differ sufficiently in the heterogeneous sector.     

Investment liberalization and international trade

This paper estimates the cross-price elasticity of exports with respect to investment costs for bilateral relations between 36 countries. We show that the effect of reducing foreign direct investment costs on exports depends on country characteristics and trade costs as predicted by the [Markusen, 1997] and [Markusen, 2002] model. When countries differ in relative factor endowments and trade costs are low, investment liberalization stimulates exports, whereas when countries are similar in terms of relative factor endowments and size, and trade costs are moderate to high, investment liberalization reduces exports.     

Gains from trade under variable returns to scale,commodity taxation,tariffs and factor market distortions

This paper examines the effect on welfare of improvements in the terms of trade and movement from autarky to free trade in the presence of variable returns to scale, production and consumption taxes, tariffs and factor market distortions. By expressing welfare in terms of a social welfare function and by considering infinitesimal changes in prices, sufficient conditions for the nonharmfulness of trade and improvements in the terms of trade are obtained which substantially weaken those obtained by Kemp and Negishi (1970).     

Dynamics and objectives of international trade

Standard international trade models universally consider maximizing the availability of inexpensive goods as the objective of international trade. They then go on to show that tariffs and other impediments to trade cause a loss of economic efficiency. Fewer goods are available in the trading nations because of the impediments. The common method of analysis is to use price / quantity curves and two-nation / two-product curves.

Here we show that international trade is far more complex. It is a vast network beyond our present ability to accurately model. It can, however, be structured as a linear program. As a linear program it has many of the characteristics of a network. The chief difference is that linear programs provide static analysis. The world trade network is dynamic. However, by structuring it as a linear program, many of the components of international trade omitted by price/ quantity and two-nation / two-product analysis can be incorporated.

An important part of any programming analysis is determination of the objective function. Several objective functions are examined, particularly with respect to employment impacts. A variable compensatory tax (VCT) is selected as a means of dealing with the dynamics and complexity of international trade. It has the potential to repatriate 6 million jobs, is simple to implement, precludes retaliation, and would bring U.S. trade into a permanent balance of ± 5%.

Credit constraints, equity market liberalizations and international trade

This paper provides evidence that credit constraints are an important determinant of international trade flows. I exploit shocks to the availability of external finance and examine the impact of equity market liberalizations on the export behavior of 91 countries in the 1980-1997 period. I show that liberalizations increase exports disproportionately more in financially vulnerable sectors that require more outside finance or employ fewer collateralizable assets. This result is not driven by cross-country differences in factor endowments and is independent of simultaneous trade policy reforms. Moreover, it obtains with equal strength in the full panel of countries as well as in both panel and event-study analyses of countries which removed capital controls during the sample period. Finally, the effects of liberalizations are more pronounced in economies with initially less active stock markets, indicating that foreign equity flows may substitute for an underdeveloped domestic financial system. Similarly, opening equity markets has a greater impact in the presence of higher trade costs caused by restrictive trade policies.     

Unions, competition and international trade in general equilibrium

We develop a two-country, multi-sector model of oligopoly in which unionised and non-unionised sectors interact in general equilibrium. The model is used to study the impact of trade liberalisation, deunionisation and firm entry on wages in unionised and non-unionised sectors, and on welfare. We find that a shift from autarky to free trade increases non-union wages and welfare, whereas the effect on union wages is ambiguous. We also show that partial deunionisation leads to higher wages in both unionised and non-unionised sectors, but only increases welfare when the proportion of unionised sectors is sufficiently low. Finally, wages in non-unionised sectors necessarily increase with firm entry, while the response of union wages and welfare depends on the trade regime.     

Financing international trade transactions

International trade transactions present unique commercial and legal risks, and hence specialized forms of financing are required.
