Endogenous market structure and the growth and welfare effects of economic integration

This paper studies the growth and welfare effects of integration in a world economy populated by global oligopolists. In economies that move from autarky to trade, growth and welfare rise because exit of domestic firms is more than compensated by entry of foreign firms so that integration generates a larger, more competitive market where firms have access to a larger body of technological spillovers that support faster growth. The effects of a gradual reduction of tariffs are different because economies start out from a situation where all firms already serve all markets. In this case, the global number of firms falls so that the variety of consumption goods and the diversity of innovation paths fall. The surviving firms, on the other hand, are larger and exploit static and dynamic economies of scale to a larger degree. These homogenization and rationalization effects work in opposite directions. Under plausible conditions, the rationalization effect dominates and growth and welfare rise.     

Market Structure and Market Access

We explore an issue at the nexus of domestic competition policy and international trade, the interaction between goods trade and market power in domestic trade and distribution sectors. We examine the effect of variations in conditions of domestic competition in services on trade volumes in goods in the cases of both linear and nonlinear import demand, including standard form CES‐based gravity models of bilateral trade flows. Theory suggests a set of linkages between service‐sector pricing and goods trade supported by econometrics involving imports of 22 OECD countries vis‐a‐vis 69 exporters. Competition in distribution services affects the volume of trade in goods. Additionally, because of interaction between tariffs and pricing, the market structure of the domestic service sector becomes increasingly important as tariffs are reduced. Indeed, depending on the degree of competition, market access concessions on tariffs may be effectively undone in some cases by changes in margins. For exporters, we find that service competition in destination markets matters most for exporters from smaller, poorer countries. Our results also suggest that while negotiated agreements leading to cross‐border services liberalisation may boost goods trade as well, they may also lead to a fall in goods trade when such liberalisation involves FDI leading to increased service sector concentration.     

Short‐term Consequences of Trade Reform for Industry Employment and Wages: Survey of Evidence from Colombia

Recent research has focused on the short‐ to medium‐term implications of trade reforms for the labour market outcomes and poverty in poor economies. This article summarises the evidence on the short‐term consequences of the Colombian trade reform initiated in 1985 for industry employment and industry wages. Although the reform reduced manufacturing tariffs on average by 40 percentage points from 1984 to 1994, tariff declines were not significantly associated with labour reallocation across sectors. The reform, however, was associated with bigger declines in relative industry wages in sectors that experienced bigger tariff cuts. This evidence is in line with the predictions of short‐ to medium‐run models of trade in which labour is not mobile across sectors. It is also consistent with the predictions of models where imperfectly competitive industries share rents with workers and trade reduces the firms’ profit margins and thus workers’ rents.     

Trade-diverting free trade agreements,external tariffs,and feasibility

There has been a proliferation of preferential trade agreements within the last two decades. This paper analyzes the effects of free trade agreements (FTAs) on external tariffs in small economies where protection decisions are made politically. Our model determines tariff rates endogenously instead of assuming they are fixed during or after the formation of FTAs as commonly done in the literature. We show that when an FTA is established, the tariff rates that apply to non-members essentially decline. More importantly, we investigate the interaction between endogenous tariff determination and the feasibility of an FTA. We find that the expectation of tariff reductions under endogenous tariffs could make an otherwise feasible FTA if tariffs were fixed become infeasible. However, if domestic import-competing sectors are relatively smaller and the government places a significant weight on political contributions relative to social welfare, an FTA with endogenous tariffs may be more likely to be feasible than an FTA assumed to fix external tariffs.

The impacts of trade liberalization on informal labor markets: A theoretical and empirical evaluation of the Brazilian case

Following trade liberalization, several developing countries experienced a sharp increase in the share of informal manufacturing employment. In this paper, I examine the impacts of trade liberalization on the labor markets of a small open economy, in an environment in which tariffs affect firms' payroll tax compliance decisions. I demonstrate that a reduction in domestic import tariffs reduces the average formal wage and show that the direction of the effect on the share of informal employment depends on the initial labor market conditions. A cut in trading partner import tariffs decreases the share of domestic informal employment and increases the average formal wage. I confirm the model's principal findings empirically, using data from the 1989–2001 Brazilian trade liberalization episode. I find the results robust to endogeneity and self-selection concerns, which are addressed, respectively, using instrumental variable and switching regression approaches.     

Exporting raises productivity in sub-Saharan African manufacturing firms

Proponents of trade liberalization argue that exporting helps firms to achieve higher productivity levels. This hypothesis is examined for a panel of manufacturing firms in nine African countries. The results indicate that exporters in these countries are more productive and, more importantly, exporters increase their productivity advantage after entry into the export market. While the first finding can be explained by selection-only the most productive firms engage in exporting-the latter cannot. The results are robust when unobserved productivity differences and self-selection into the export market are controlled for using different econometric methods. Scale economies are shown to be an important channel for the productivity advance. Credit constraints and contract enforcement problems prevent firms that only produce for the domestic market from fully exploiting scale economies.

The Welfare Loss of the Voluntary Export Restraint For Japanese Automobiles

The welfare loss from the voluntary export restraint (VER) on Japanese automobiles was estimated for the first year of the VER (April 1, 1981 to March 31, 1982). The impact of quantity reductions on the price of Japanese and domestic automobiles was used to estimate the welfare loss. Losses were estimated separately for the domestic small car market and the Japanese market in view of the existence of product differentiation. Welfare losses ranged from $446 million to $1,386 million depending on the price elasticity of demand assumed for Japanese automobiles. The welfare loss for domestic automobiles accounted for only a small proportion of this loss. The VER had a minor impact on the domestic automobile industry where sales remained low due to general economic conditions and limited substitutability between domestic and Japanese cars. However, the limited assistance provided by the VER to the domestic automobile industry entailed considerable costs as demonstrated by the magnitude of the welfare loss. A considerable part of this loss could have been avoided if other forms of trade protection such as tariffs had been used instead of the VER.     

Tariffs, quality reversals and exit in vertically differentiated industries

In a vertically differentiated industry a domestic and a foreign firm first choose the quality of their goods and then compete in quantities, or prices, in the home market. We investigate the cases in which a tariff is chosen before, or after, the firms’ quality decision. These cases are referred to as the ex-ante and the ex-post game, respectively. Optimal ex-post tariffs are positive and ensure that the domestic firm always produces the high quality good. The optimal ex-ante tariff is prohibitive and welfare under domestic monopoly is lower than under ex-post tariffs, unless firms compete in prices and the domestic firm is high quality.     

Does and How Does Globalisation Matter at the Industry Level?

In this paper we develop a concept of globalisation at the micro level defined as the exposure of a productivity follower industry in one country to the productivity leader in another country. Globalisation is measured by the intensity of contacts through trade and foreign direct investment. In a simple model and empirically we show that the exposure of a productivity follower to competition with the leader is highly correlated with the productivity gap of this industry. Competition restricted to one region such as Europe, or North America, or the Far East, is not sufficient to achieve highest productivity levels. Moreover, it turns out that foreign direct investment (FDI) has a weight in the globalisation index at least equal to trade. FDI can contribute directly to higher levels of domestic productivity by transferring the best production practices, and put pressure on other domestic producers to improve. The impact of trade on globalisation can be weakened by tariffs and non‐tariffs.     

Industry concentration and optimal discriminatory commercial policies

We derive the characteristics of firm-specific strategic trade policies when industries consist of heterogenous firms, and show how the informational requirements for policy design are thereby expanded. A knowledge of the Herfindahl index of concentration of the foreign industry is required for the design of optimal protection for domestic firms. It is shown that optimal firm-specific tariffs reduce the degree of foreign concentration, thus shifting rents to domestic firms.     

Intra-industry trade under perfect monopolistic competition

This paper applies the analysis of perfect monopolistic competition, developed earlier by the author, to the problem of intra-industry trade. It is shown that a high volume of intra-industry trade can be expected even between economies which are identical in all respects and thus between which no trade would be predicted on the basis of comparative advantage. It is shown that similar economies may generate more mutual trade than dissimilar ones, and that tariffs may sometimes increase intra-industry trade.     

Trends in protectionism: Anti-dumping and trade related investment measures

The importance of non-tariff barriers in restricting free trade has risen during recent years. Due to their selectivity non-tariff barriers may distort trade even more significantly than tariffs. Developing countries and economies in transition are often most negatively affected.     

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).     

中国稀土出口市场势力的实证研究

本文实证研究中国稀土出口贸易的市场势力。计量研究发现,中国稀土出口贸易的实际市场势力比较微弱,出现"寡头"地位与市场势力缺乏共存的现象。利用微观贸易数据,发现中国稀土出口贸易呈现较强的竞争性市场结构特征,因此,虽然具有国家总量上的"寡头"地位,但却只能获得竞争性定价结果,出口贸易市场势力的缺乏成为必然。利用生存能力法对中国稀土出口贸易最优规模经济量进行估计,发现稀土贸易(生产)的最优规模经济区间为0.5-10%的市场份额区间,其他区间则是规模不经济的,为中国稀土贸易市场势力的增强和政策调整提供了实证依据。

Multilateral Agricultural Trade Liberalisation: The Contrasting Fortunes of Developing Countries in the Doha Round

An applied general equilibrium model is used to assess the impact of multilateral trade liberalisation in agriculture, with particular emphasis on developing countries. We use original data, and the model includes some specific features such as a dual labour market. Applied tariffs, including those under preferential regimes and regional agreements, are taken into account at the detailed product level, together with the corresponding bound tariffs on which countries negotiate. The various types of farm support are detailed, and several groups of developing countries are distinguished. Simulations give a contrasted picture of the benefits developing countries would draw from the Doha development round. The results suggest that previous studies have neglected preferential agreements and the binding overhang (in tariffs as well as domestic support), and have treated developing countries with a high level of aggregation and been excessively optimistic about the actual benefits of multilateral trade liberalisation. Regions like sub‐Saharan Africa are more likely to suffer from the erosion of existing preferences. The main gainers of the Doha Round are likely to be developed countries and Cairns Group members.     

Determinants of domestic credit levels in emerging markets: The role of external factors

This paper empirically examines the determinants of domestic credit expansion across a wide range of 24 emerging market economies. We use a dynamic panel data estimation technique to investigate the short-run and long-run effects of internal demand and external supply factors, external balance, different measures of trade openness and global uncertainty on domestic credit. We find that loose monetary policy in the domestic market, differences between domestic and global lending rates and real trade openness positively contribute to domestic credit levels. The findings also show that external balance and perceptions of global tail risk negatively affect domestic credit levels.
