A natural experiment for identifying the impact of ‘natural’ trade barriers on exports

The paper investigates the relative importance of trade policy and ‘natural’ sources of export taxation in Malawi, a landlocked African economy. These sources of export taxation are in turn used to explore how export supply would respond to trade liberalisation as opposed to measures which lower other international trade costs. The findings indicate that trade policy barriers are now only a limited source of ‘true’ export taxation and that trade policy reform needs to be complemented with reforms to reduce international trade, including transport, costs.     

TRANSPORTATION INFRASTRUCTURE INVESTMENTS AND TRADE LIBERALIZATION*

This paper examines the gains from cooperative agreements on transportation infrastructure investments when there are terms of trade and technological spillovers between countries. In a two ‐country model, cooperation on investment levels will result in a lower level of transport costs. However, the cooperative equilibrium may have a higher or lower level of infrastructure investment between the partner countries in the case of preferential liberalization. The paper also addresses the desirability of linking trade and infrastructure agreements when investment choices can be used strategically.     

Endogenous trade bloc formation in an asymmetric world

This paper investigates how variations in endowments and the structure of preferences impact on the coalition formation decisions of asymmetric countries. There exist relatively few general results on the relationship between country characteristics and trade bloc formation. Here, new light is shed on this issue by systematically simulating bloc formation and by explicitly analysing the blocking behaviour of coalitions. A general equilibrium model of world trade is implemented with equilibrium coalition formation being modelled using the equilibrium concept of the core. It is found that global free trade is observed when all countries are similar. Customs unions tend to form between countries with ‘adjacent’ consumer preferences or with ‘adjacent’ endowments of their export commodity. Finally, in contrast to the existing literature but consistent with observed behaviour, it is found that free trade areas often Pareto dominate customs unions, provided consumer preferences differ sufficiently.     

How do transport costs affect firms’ exports? Evidence from a vanishing bridge

In this paper we provide estimates of the effects of international transport costs on firms’ exports and disentangle the channels of these effects. In so doing, we use a unique dataset consisting of highly disaggregated transaction-level trade and transport cost data and, in order to account for endogeneity, we exploit the exogenous variation in these costs associated with the non-trade related closure of the main bridge connecting two countries.     

Dynamic effects of trade openness on financial development

This paper employs the Pooled Mean Group (PMG) approach of Pesaran et al. (1999) to study the dynamic effects of trade openness on financial development. The advantage of the PMG estimator over other dynamic panel econometric techniques is that it allows short-run coefficients, speeds of adjustment and error variances to vary across countries, with cross-country homogeneity restrictions only on long-run parameters. Our results spanning 88 countries over 1960–2005 show that a positive long-run relationship between trade openness and financial development coexists with a negative short-run relationship. But when splitting the data into different income or inflation groups, this finding is observed only in relatively low-income countries or high-inflation economies.     

Testing the growth effects of structural change

Against the backdrop of Baumol's model of ‘unbalanced growth’, a recent strand of literature has presented models that manage to reconcile structural change with Kaldor's ‘stylized fact’ of the relative constancy of per-capita real GDP growth. Another strand of literature goes beyond this, arguing that the expenditure shifts toward Baumol's ‘stagnant’ sector stimulate rather than dampen long-term economic growth because of the human capital-accumulating nature of major ‘stagnant’ services (like health care and education). This paper tests the relationship between structural change and economic growth empirically by means of a Granger-causality analysis of a panel of 18 OECD countries.     

Firms’ location decision across asymmetric countries and employment inequality

This paper analyzes the effect of globalization (lower trade costs) on production and trade patterns if, firms are vertically linked, stages of production differ in labor-factors intensity and countries differ in labor-factors prices. In order to reflect the “Continental Europe” experience, relative wages are assumed fixed and spatial changes in production are translated into changes in relative (skilled to unskilled) employment levels. The asymmetry in factors prices across countries results in a unique agglomeration equilibrium for a broad range of trade costs. At low trade costs, firms’ location depends on production costs—vertical specialization occurs. This paper also provides a consistent explanation of the observed increase in employment inequality between skilled and unskilled workers in relatively high-unskilled wage countries.     

The U.S. trade imbalance and real exchange rate: An application of the heterogeneous panel cointegration method

The United States economy suffers from persistent trade deficits, arising from the so-called ‘global external imbalance’. Can the depreciation of the US dollar improve this phenomenon? This study for the first time applies the heterogeneous panel cointegration method to examine the long-run relationship between the real exchange rate and bilateral trade balance of the U.S. and her 97 trading partners for the period 1973–2006. Using new annual data, the empirical results indicate that the devaluation of the US dollar deteriorates her bilateral trade balance with 13 trading partners, but improves it with 37 trading partners, especially for China. In the panel cointegrated framework, a long-run negative relationship between the real exchange rate and the bilateral trade balance exists for the U.S.     

Calibrating spatial models of trade

Empirical spatial models of trade that are based on a mathematical programming specification often exhibit a large discrepancy between the equilibrium solution and the observed demand, supply and levels of trade flows among countries. This discrepancy may be due to several causes. Assuming, however, that a trade model is not misspecified – in the sense that behavior of the economic agents involved in the specific commodity markets has been included in the study and that the relevant policy instruments have been properly taken into account – the cause of discrepancy may be traced either to imprecision of unit transaction costs or to imprecision in the measurement of the demand and supply functions' parameters, or both. Policy assessments based on this type of imprecise models are distorted. This paper presents a methodology for calibrating mathematical programming spatial trade models of increasing complexity, from the one-commodity case to a multi-commodity model with asymmetric slope matrices of demand and supply functions. The proposed calibration procedure identifies corrections of imperfectly measured parameters. The calibrated models generate solutions that exactly reproduce quantities produced and consumed in all countries, as well as trade flows among all pairs of countries, observed in a given base year. Such models may then serve as a springboard for assessing the impact of various policy changes on economic agents in the countries under study.     

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.     

Trade creating free trade areas and the undermining of multilateralism

This paper indicates that the consequences of regional trade agreements for the world trade system may be deceiving—an arrangement's apparent virtue may constitute the source of its drawback. In a model where governments have political, as well as economic, motivations, I show that a free trade area induces its members to reduce protection against the non-members, and to do so sufficiently deeply to generate overall trade creation. Trade creation amplifies the excluded countries’ access to the integrating markets, but also reduces their extra gains from multilateral liberalization. Thus, trade creation can reverse the support of the excluded countries to liberalization on a multilateral basis. This is more likely to happen when governments outside the free trade area are more responsive to special interests.     

Trade effects of monetary agreements: Evidence for OECD countries

This paper analyses the effects of monetary agreements on trade flows using a sample of 25 OECD countries over the period 1950-2004. We find that these agreements have boosted intra-bloc trade. This result especially applies to the case of the euro. More importantly, in contrast to regional trade agreements, all monetary agreements analysed show evidence of trade-creating effects with third countries. Finally, only the euro shows a symmetric impact for the trade-creating effect with non-members, that is, using the euro promotes both the Eurozone's exports and its imports to non-Eurozone markets to a similar extent.     

Competition in the traditional sector does not matter for the ‘Core–Periphery’ model

We modify Paul Krugman’s (1991) ‘Core–Periphery’ model by replacing the traditional competitive sector with a monopolistically competitive one. We show that the structure of spatial equilibria remains the same as in the original model. This result continues to hold true under Cournot or Bertrand oligopolistic competition with free entry in the traditional sector. The key factor that explains why the nature of competition in the traditional sector does not matter for the spatial equilibria is constant expenditure shares–due to nested Cobb–Douglas and CES preferences–which imply that trade in the traditional sector is independent from its sectoral characteristics.     

External wealth, the trade balance, and the real exchange rate

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.     

Loafing or learning?—the demand for informal education

Using detailed time use data for Germany a positive correlation is found between the level of schooling and time investments in informal education. Two hypotheses explain this observation: (1) highly educated people have higher opportunity costs of their leisure time and thus prefer leisure activities which add to their market productivity (wage effect) and (2) highly educated people have a preference for ‘high quality’ leisure (taste effect). The demand for informal education is derived in a household production model accounting for both explanations. An empirical investigation finds evidence for both effects with the taste effect being more important.     

Does antidumping use contribute to trade liberalization in developing countries?

Abstract .  Some supporters of antidumping have argued that this procedure serves as a kind of 'safety valve' for protectionist pressure. In this paper, we investigate whether there is empirical evidence that the use of antidumping actions has contributed to ongoing tariff reductions over the period 1988 to 2004 in a sample of 23 developing countries, some of which have become aggressive users of antidumping in recent years. The evidence is not supportive of the safety valve argument for these countries. Instead, evidence suggests that past use of antidumping may have led to less rather than more trade liberalization.     

Employment protection, international specialization, and innovation

We develop a model to analyze the implications of firing costs on incentives for R&D and international specialization. The key idea is that countries with a rigid labor market will tend to produce relatively secure goods, at a late stage of their product life cycle. Consequently, their researchers tend to specialize in ‘secondary innovation’ which improves existing products, rather than ‘primary innovation’ which introduces new products. This is roughly consistent with the observed pattern of R&D in Europe versus the U.S. Employment protection does not necessarily harm the country where it prevails, but typically reduces world welfare and the world number of goods.     

The export price index with the effect of variety and an empirical analysis

The standard international trade models predict that economic growth induces decreasing export prices. Korea has recorded sustainable economic and export growth, and its export prices have been deteriorating over the last decades. Unlike the standard assumption of one good per country, the new theoretical approach by Krugman [Krugman, P. (1980) ‘Scale Economies, Product Differentiation, and Pattern of Trade’. American Economic Review 70, 950–959, Krugman, P. (1989) ‘Differences in income elasticities and trends in real exchange rates’. European Economic Review, 33, 1055–1085.], and Helpman and Krugman [Helpman, E. and Krugman, P. (1985), Market structure and foreign trade: increasing returns, imperfect competition, and international economy, The MIT Press, Cambridge, MA.] takes into account varieties of goods produced in each country. And many studies suggest that traditional estimates without variety effect have been rather under-stated. Therefore this paper develops a proper modeling for quantifying the impact of export variety on an exact export price index. Throughout the period (1984–2000), the conventional export price index without variety effect leads to under-state Korea's export price by 89.3%. This paper shows that the fall in Korean export prices has been offset by the effect of export variety. This paper emphasizes the effect of export variety on international trade.     

Alliances and negotiations

Negotiations often occur not between individuals but among groups (companies, trade unions, political parties, etc.) each representing composite interests, whose bargaining behaviour is regulated by some collective decision mechanism. In this paper we provide a natural model of such circumstances. We formalise the notion of ‘alliance’ and show how different preference aggregation procedures within the alliance affect the bargaining outcome. In particular, we find that unanimity procedures lead to ‘more aggressive’ negotiating tactics than majority procedures.     

The pattern of specialization and economic growth: The resource curse hypothesis revisited

This paper explores the relation between countries’ pattern of trade specialization and long-term economic growth. It shows that countries specializing in the export of natural resource based products only fail to grow if they do not succeed in diversifying their economies and export structure. This conclusion follows from an empirical investigation that has three innovative features. First, it uses a dynamic panel data analysis. Secondly, it employs disaggregated trade data sets to elaborate different measures of trade specialization that distinguish between unprocessed and manufactured natural resource products and are informative about the countries’ trade diversification experience, their link to world demand trends and involvement in intra-industry trade. The final innovative aspect of the paper relates to our empirical findings: it is only specialization in unprocessed natural resource products that slows down economic growth, as it impedes the emergence of more dynamic patterns of trade specialization.
