The effects of foreign shocks when interest rates are at zero

In a two‐country DSGE model, the effects of foreign demand shocks on the home country are greatly amplified if the home economy is constrained by the zero lower bound on policy interest rates. This result applies even to countries that are relatively closed to trade such as the United States. Departing from many of the existing closed‐economy models, the duration of the liquidity trap is determined endogenously. Adverse foreign shocks can extend the duration of the trap, implying more contractionary effects for the home country. The home economy is more vulnerable to adverse foreign shocks if the neutral rate is low—consistent with “secular stagnation”—and trade openness is high.     

Estimating the impact of country‐level policy restrictions on services trade

Standard techniques used to estimate gravity equations, rely on bilateral variation to identify the effect of trade barriers on bilateral trade flows. In this paper, I develop a method that estimates the effects of country‐level variables on trade between countries in the presence of firm heterogeneity and country selection into trade, a natural extension of existing empirical models of international trade. I implement the method in services data, where available measures of trade policy provide information on the average level of regulations restricting entry into a country. The results suggest that policy barriers are important determinants of services trade flows.     

Shared Renewable Resources: Gains from Trade and Trade Policy

This paper examines the effects of international trade and trade policy in a two‐country, two‐good model with an open‐access renewable resource that is internationally shared. We show that both countries may still benefit from trade when they specialize in the production of their comparative advantage good, although the shared resource is reduced by trade. In addition, we demonstrate that the steady state utility of a resource‐good importing country may be reduced by trade, even if it specializes in the production of a non‐resource good. Import tariffs and export taxes on a resource good may increase or decrease the shared stock level depending on the production patterns in a trading steady state. The trade policy is likely to be Pareto‐improving when the shared stock rises, while both countries may be made worse off by the trade policy when the shared stock falls.

A Fragmented China: Measure and Determinants of Chinese Domestic Market Disintegration

This paper studies the degree of integration of China's domestic market and investigates the determinants of inter‐provincial trade barriers under the rubric endogenous trade policy theory. I rely on industry‐level trade flows extracted from provincial input–output tables to develop a model that analyzes the magnitude and evolution of Chinese provinces’ engagement in domestic trade by computing all‐inclusive indicators of trade barriers. Results underline that over the 1990s, not only was China's domestic market fragmentation along provincial borders great, but it also has become more severe at least between 1992 and 1997. The investigation of province‐level and industry‐level trade barriers confirms the relevance of applying the framework of endogenous protection to explain the level of impediments to trade between Chinese provinces. Findings emphasize that provinces’ domestic trade protection pursues a dual objective of socio‐economic stability preservation and fiscal revenues maximization.     

Reconciling Observed Tariffs and the Median Voter Model

Median voter theory applied to trade policy predicts positive tariffs in capital‐abundant countries and negative tariffs in labor‐abundant countries. Negative tariffs are rare, and this paper reconciles the median voter theory with observed protectionism across countries. By considering large countries, I show the optimal tariff is a sum of the median voter component and a positive term of trade component. Positive terms of trade effects raise tariffs in all countries, and can overcome the negative median voter component in labor‐abundant countries. Testing the tariff prediction with cross‐section and panel data from the 1990s, I show the median voter component is negative in labor‐abundant countries and positive in capital‐abundant countries. As expected, terms of trade effects raise tariffs across all countries and are stronger among nonmembers of the WTO.     

Growth and Deeper Regional Integration in a Three-Country Model

An endogenous growth model of three countries is used to investigate the dynamic effects of deeper economic integration between two countries in the presence of an outside world. The paper looks at the long-run effects of inner-union trade liberalization, the union's external trade policy, and of the relaxation of the inner-union barriers to migration. It is shown that regional integration via inner-union trade liberalization can lead very well to a decline of the steady-state growth rates.     

Did the Uruguay Round Agreement on Agriculture Affect Trade Flows? An Empirical Investigation for Meat Commodities

The Uruguay Round Agreement on Agriculture (URAA) was designed to reduce trade barriers and temper domestic and export policies that affect trade flows in agricultural commodities. This paper employs a dynamic framework to estimate the effects of the URAA on trade flows, as measured by export volumes, of three meat commodities. The model controls for several important factors, including regional trade agreements, and finds that the URAA had mixed effects on meat exports. Several complicating factors and policy responses, including increasing use of non-negotiated trade barriers, smaller export subsidies and domestic support, and limited effectiveness of market access provisions, explain the mixed empirical results.     

Regulatory Entry Barriers,Rent Shifting and the Home Market Effect

This paper introduces regulatory entry barriers in a model of the home market effect. The entry barriers generate local rents that have unexpected but significant implications. First, the home market effect is magnified. Second, when countries are sufficiently unequal in size and rents are sufficiently large, symmetric reductions in trade costs reduce welfare in the small country. Third, entry barriers increase the large country's market size and, surprisingly, can increase its welfare. Fourth, a unilateral increase in trade protection shifts foreign rents to the home country. This rent‐shifting effect amplifies the standard production relocation motive for trade policy intervention.     

Inequality and Trade Policy: The Pro‐Poor Bias of Contemporary Trade Restrictions

This paper studies the pro‐poor bias of trade policy in India by estimating the household welfare effects of removing the current protection structure. The elimination of a pro‐poor trade policy is expected to have a negative differential welfare effect at the low end of the distribution. The paper first constructs trade restrictiveness indexes for household consumption items and industries using both tariffs and non‐tariff barriers. The results indicate that Indian trade policy is regressive through the expenditure channel as it disproportionately raises the cost of consumption for poorer households, while it is progressive through the earnings channel. Based on the net welfare effects, the elimination of the current trade protection structure is estimated to reduce inequality. These results indicate that a trade policy that is progressive through the earnings channel may induce a price effect that is regressive through the expenditure channel.     

Explaining Export Performance through Inputs: Evidence from Aggregated Cross‐country Firm‐level Data

Which trade barrier related to intermediate inputs forms a greater burden on the export performance of firms in developing countries? Using aggregated cross‐country firm‐level data covering 43 mostly developing economies, this paper estimates the marginal importance of the impact of various intermediate input trade cost barriers, namely tariffs, non‐tariff barriers (NTBs) and services barriers, on firms' export behavior. In a cross‐sectoral setting, this paper takes the firm's export performance in goods as a central focus to study the effects of these different trade barriers through the exporting firm's choice of use of intermediate inputs. The results show that the most significant trade barriers on inputs that impede export performance in developing countries are mainly NTBs and restrictions of services.     

Inequality,growth, and environmental quality trade‐offs in a model with human capital accumulation

This paper develops a simple endogenous growth model where pollution exposure and vulnerability are unequally spread across the population, and growth and distribution are endogenous. In this set‐up, we investigate whether trade‐offs between growth, distributional, and environmental concerns may emerge. We show that a tighter environmental policy reduces income inequality and can improve both growth and total welfare. Immediate welfare losses, though, do occur, and are larger for countries that start at low levels of environmental quality (e.g. developing countries).     

Differentiated Products,Divided Industries: Firm Preferences over Trade Liberalization

The recent focus on firms in international trade suggests two conjectures about preferences over trade policy – only the most productive firms should support freer trade, and industries can be internally divided over reciprocal liberalization. This paper clarifies the content and scope of these claims. The most productive firms are generally not the greatest beneficiaries from trade liberalization and may oppose further liberalization due to increased competition in export markets from compatriot firms. Exporting industries will feature no support for trade if foreign competition is too strong or barriers too unequal. The key analytic factor generating intra‐industry division is product differentiation, both directly, by increasing export opportunities for less efficient firms, and by inducing home market effects wherein larger countries are more competitive. The implications of these findings for the distributional effects of liberalization and the study of trade politics are discussed.     

A Ricardian Model with Endogenous Comparative Advantage and Endogenous Trade Policy Regimes

This paper develops a Ricardian model with transaction costs and endogenous and exogenous comparative advantages. It shows that the level of division of labour and trade increases as transaction conditions improve. It identifies the conditions for trade negotiations that result in zero tariff rates and the conditions for the coexistence of unilateral tariff protection and unilateral laissez faire policies. The model may explain the policy transformation of some European governments from Mercantilism to laissez faire in the 18th and 19th century and policy changes in developing countries from protection tariff to trade liberalization and tariff negotiation.     

Factor Endowments,Democracy, and Trade Policy Divergence

We develop a stochastic model of electoral competition in order to study the economic and political determinants of trade policy. We model a small open economy with two tradable goods, each of which is produced using a sector‐specific factor (e.g., land and capital) and another factor that is mobile between these tradable sectors (labor); one nontradable good, which is also produced using a specific factor (skilled labor), and an elected government with the mandate to tax trade flows. The tax revenue is used to provide local public goods that increase the economic agents’ utility. We use this general equilibrium model to explicitly derive the ideal policies of the different socioeconomic groups in society (landlords, industrialists, labor, and skilled workers). We then use those ideal policies to model the individual probabilistic voting behavior of the members of each of these socioeconomic groups. We use this model to shed light on how differences in the comparative advantages of countries explain trade policy divergence between countries as well as trade policy instability within countries. We regard trade policy instability to mean that, in equilibrium, political parties diverge in terms of the political platforms they adopt. We show that in natural resource (land)–abundant economies with very little capital, or in economies that specializes in the production of manufactures, parties tend to converge to the same policy platform, and trade policy is likely to be stable and relatively close to free trade. In contrast, in a natural resource–abundant economy with an important domestic industry that competes with the imports, parties tend to diverge, and trade policy is likely to be more protectionist and unstable.     

A spatial equilibrium analysis of trade policy reforms on the world wheat market

Since a few countries produce most of the world's wheat, and consumption is widespread across the world, wheat is one of the most commonly traded agricultural commodities. In recent years, the wheat market has been going through difficult phases as wheat prices are depressed. The fall in wheat prices is attributed to a supply glut and restrictive trade barriers. This study develops a large-scale spatial equilibrium trade model for wheat to analyse the effects of removing trade barriers (tariffs and subsidies) on each country's/region's price, supply, demand, trade, welfare, and bilateral trade flows. The results show that trade liberalization leads to an increase (decrease) in prices in the exporting (importing) countries. Production and exports increase in the exporting country, and consumption and imports increase in the importing country. Consequently, the volume of trade also increases. The welfare of most countries rises, and thus, world welfare also rises.     

Vertical Specialization and International Business Cycle Synchronization*

We explore the impact of vertical specialization—trade in goods across multiple stages of production—on the relationship between trade and business cycle synchronization across countries. We develop an international business cycle model in which the degree of vertical specialization varies with trade barriers. With perfect competition, we show analytically that fluctuations in measured total factor productivity are not linked across countries through trade. In numerical simulations, we find little dependence of business cycle synchronization on trade intensity. An extension of the model to allow for imperfect competition has the potential to resolve these shortcomings.     

Inflation‐Growth Profiles Across Countries: Evidence from Developing and Developed Countries

There is growing evidence from multi‐country studies indicating that there is a turning point in the relationship between inflation and economic growth beyond which the detrimental effects of high inflation offset the stimulating effects of mild inflation on growth. However, it is not clear whether it is appropriate to assume an identical turning point in the inflation and growth relation across countries at various stages of development. Using a non‐linear specification and the data from four groups of countries at various stages of development, this paper examines the possibility for a family rather than a single inverted U relation across countries at various stages of development. The estimated turning points are found to vary widely from as high as 15% per year for the lower‐middle‐income countries to 11% for the low‐income countries, and 5% for the upper‐middle‐income countries. No statistically detectable, long‐run relationship between inflation and growth is evident for the OECD countries. The results indicate the potential bias in the estimation of inflation–growth nexus that may result from combining various countries at different levels of development. The existence of such a degree of heterogeneity across countries at various stages of development also suggests the inappropriateness of setting a single, uniform numerical policy target applicable to all (developing) countries.     

Institutional quality and the effectiveness of aid for trade

Trade policy barriers and high transaction costs hinder developing countries from taking the full advantages of the global trading system. In order to help developing countries overcome the problem, the World Trade Organization (WTO) launched the Aid for Trade (AFT) initiatives in its Ministerial Conference held in Hong Kong in 2005. We examine the effects of AFT inflows on bilateral trade costs facing 133 developing countries while accounting for differences in their location on the contours of various measures of institutional quality. Our results from the estimation of a mixed effects (random-intercept and random-coefficient) model indicate that institutional quality significantly affects the extent to which AFT reduces bilateral trade costs. An important policy implication of our findings is that an economically robust and sustainable reduction in bilateral trade costs facing developing countries requires the presence of both promulgated and effectively functioning institutions such as regulatory power and the rule of law.     

The impact of inflation targeting: Testing the good luck hypothesis

Starting in the mid‐1980s, the level and volatility of inflation decreased across industrial countries. The inflation stabilization can be explained by a shift in monetary policy or by a lucky period of low volatility in business cycle shocks. To test the “good luck hypothesis,” we examine the inflation experience of Canada, one of the earliest and most successful adopters of an inflation targeting monetary policy. We Kalman‐filter the historical structural shocks consistent with an estimated dynamic stochastic general equilibrium (DSGE) model of the Canadian economy. The estimated shocks are used to build counterfactual histories. The good luck hypothesis can explain only a minor portion of the change in the path and volatility of inflation after the shift in policy. Most of inflation and output stabilization is accounted by the impact on expectations. Unconditionally, the inflation targeting policy does not improve on the previous policy in terms of inflation volatility, but supports a more favourable trade‐off, reducing substantially output volatility.
