HIERARCHICAL TRADE

Commodity trading is typically organized hierarchically: Large‐scale trade takes place at the global price system while individuals trade at local price systems within their countries. Agencies or trading houses establish the link between these different market places. In this paper, we devise a framework to study this type of hierarchical trade. We identify the free trade and the autarky equilibrium as polar cases. We show that no other two‐stage market equilibria exist if the commodity space is two‐dimensional. An example demonstrates that other, so‐called intermediate equilibria exist for three‐dimensional commodity spaces. We then provide an explicit construction of special classes of intermediate equilibria. Moreover, we study the consequences when some countries control the agency that organizes trade at the global level and we analyze the role of international goods arbitrage. Finally, we show that profit‐maximizing agencies may not promote free trade outcomes. (JEL D43, D50, F10)     

THE IMPACT OF TRADE COSTS ON FIRM ENTRY,EXPORTING, AND SURVIVAL IN KOREA

This study examines how changes in trade costs have affected entry, exit, productivity, and exporting in the Korean manufacturing sector. We verify several predictions of heterogeneous‐firm models of international trade. For example, falling import‐trade costs are associated with less entry and lower market shares among existing domestic firms, and higher total factor productivity for Korean manufacturing as a whole. The size of firms plays an important role in many of our results. New domestic firms are more likely to be small, but large firms are less likely to exit and more likely to have an increase in total factor productivity. (JEL F10, D24)     

TRADE COSTS AND TRADE COMPOSITION

In this paper, we investigate whether countries' trade costs act like other national endowments by affecting the composition of countries' exports. Using an econometric approach that controls for endogeneity by accounting for potentially relevant omitted variables, we find strong evidence for a sample of 37 industrialized and transition countries that national trade costs systematically affect the composition of trade and can be viewed therefore as a source of comparative advantage. Industries located in countries with low trade costs capture significantly higher shares of world exports, where this effect is stronger in trade cost intensive industries. (JEL F11, F14)     

FINANCIAL CONTAGION ON THE INTERNATIONAL TRADE NETWORK

We combine data on international trade linkages with a network approach to map the global trading system as an interdependent complex network. This enables us to obtain indicators of how well connected a country is into the global trading system. We use these network‐based measures of connectedness to explain stock market returns during recent episodes of financial crisis. We find that a crisis is amplified if the epicenter country is better integrated into the trade network. However, target countries affected by such a shock are in turn better able to dissipate the impact if they are well integrated into the network. A network approach can help explain why the Mexican, Asian, and Russian financial crises were highly contagious, while the crises that originated in Venezuela and Argentina did not have such a virulent effect. We suggest that a network approach incorporating the cascading and diffusion of interdependent ripples when a shock hits a specific part of the global trade network provides us with an improved explanation of financial contagion.

THE THEORY OF INTERSTELLAR TRADE

This article extends interplanetary trade theory to an interstellar setting. It is chiefly concerned with the following question: how should interest charges on goods in transit be computed when the goods travel at close to the speed of light? This is a problem because the time taken in transit will appear less to an observer traveling with the goods than to a stationary observer. A solution is derived from economic theory, and two useless but true theorems are proved. (JEL F10, F30)     

TRADE COSTS AND JOB FLOWS: EVIDENCE FROM ESTABLISHMENT‐LEVEL DATA

Changes in the costs of trading inputs or final goods affect establishment‐level job flows. Using a longitudinal database containing the universe of manufacturing establishments in California from 1992 to 2004, we find that a decline in input or final‐good trade costs is associated with job destruction in the least productive establishments, job creation in the most productive establishments, and an increase in the death likelihood of the least productive establishments. The evidence is consistent with predictions of models of trade with heterogeneous firms. Additionally, the evidence shows that the effects of input trade costs on establishment‐level job flows are larger than the effects of final‐good trade costs. (JEL F14, F16)     

GRAVITY REDUX: MEASURING INTERNATIONAL TRADE COSTS WITH PANEL DATA

Barriers to international trade are known to be large but because of data limitations it is hard to measure them directly for a large number of countries over many years. To address this problem, I derive a micro‐founded measure of bilateral trade costs that indirectly infers trade frictions from observable trade data. I show that this trade cost measure is consistent with a broad range of leading trade theories including Ricardian and heterogeneous firms models. In an application I show that U.S. trade costs with major trading partners declined on average by about 40 between 1970 and 2000, with Mexico and Canada experiencing the biggest reductions. (JEL F10, F15)     

INTERNATIONAL TRADE AND LABOR‐MARKET DISCRIMINATION

Discrimination reduces the matching probability and output in the skill‐intensive differentiated‐product sector so that discrimination‐induced comparative advantage may overshadow technological comparative advantage in determining the pattern of trade. Trade liberalization generates a decrease in the skilled‐worker wage gap in the country that is an exporter of goods from the simple sector but increases it in the country that is a net exporter of differentiated products. Trade liberalization has an opposite effect on firms. In the country that is an exporter of simple goods, trade liberalization reduces the profits of the nondiscriminatory firms by more than those of the discriminatory firms. (JEL F16, F66, J71)     

INTERNATIONAL NARCOTICS TRADE,FOREIGN AID,AND ENFORCEMENT

Using a general equilibrium model of a developing narcotics‐producing and ‐exporting economy, we analyze the economic effects of policies designed to restrict the production and trade of narcotics: foreign aid tied to anti‐narcotics law enforcement activities, demand reduction policies, and alternative development policies. We characterize the problem as one of serious factor market distortions introduced by illicit production and enforcement. While aid to enforcement generally reduces the production and export of narcotics, it is less effective for economies with market power, and under plausible conditions may raise narcotics output and have negative welfare implications for the recipient. (JEL F1)     

FREE TRADE AGREEMENTS AS DYNAMIC FARSIGHTED NETWORKS

In the presence of multilateral negotiations, are Free Trade Agreements (FTAs) necessary for, or will they prevent, global free trade? I answer this question using a dynamic farsighted model of network formation among asymmetric countries. Ultimately, FTAs prevent global free trade when there are two larger countries and one smaller country but FTAs can be necessary for global free trade when there are two smaller countries and one larger country. The model provides insights into the dynamics of recent real‐world negotiations and recent results in the literature on the empirical determinants of trade agreements. (JEL C71, F12, F13)     

THE HOME MARKET EFFECT IN INTERNATIONAL ARMS TRADE

I show that military spending contributes to international arms proliferation through a push effect: large demand encourages production growth in the domestic market if transport costs are non‐negligible. Under increasing returns to scale, the country can then supply weapons on the global market at low prices. This is a manifestation of the home market effect (HME), which states that countries with higher demand for a differentiated good will be net exporters of that good. I construct a monopolistic competition model of international trade that accounts for differences in demand across countries, and test its predictions using post‐Cold War data. (JEL F1, H5, R1)     

WHEN IS TRADE PROTECTION GOOD FOR GROWTH?

The empirical relationship between trade protection and economic growth is surprisingly fragile, as shown in a number of other papers. We address one possible explanation for these findings: that the relationship is contingent on the pattern of comparative advantage, following the endogenous growth literature. Our findings suggest that such contingencies do in fact exist—in particular, the correlation between tariffs and growth is strong and positive for skill‐abundant countries—and are robust to the choice of control variables. (JEL F13, F43, O19, O24)     

THE WELFARE IMPACT OF TRADE LIBERALIZATION

This paper analyzes the distributional welfare impact of trade liberalization reforms on heterogeneous households. We develop a static applied general equilibrium model, and using a Social Accounting Matrix and Household Expenditure Survey, we calibrate it to match Slovenian data. We simulate the case of Slovenia joining the EU and quantify its welfare impact on households that differ in terms of age, income, and education. Additionally, we compare this benchmark case with two alternative scenarios: (1) a free trade agreement between Slovenia and the EU and (2) a custom union arrangement where tariff revenues are rebated proportionally to the households. We find that while trade liberalization leads to falling consumer prices, increased production in the export sectors, and aggregate welfare gains, the differentiated welfare impacts across heterogeneous households vary in their degrees. (JEL D58, F14, F15)     

INTERNATIONAL TRADE AND THE COMPOSITION OF LABOR MARKET TURNOVER

The composition of labor market turnover is shown to influence patterns of international trade. Job and worker turnover have opposing marginal effects on industry export intensity, highlighting the importance of relative turnover shares on either side of the labor market, as opposed to total volumes of labor mobility, in shaping economic outcomes. Industries with relatively greater shares of worker turnover export more of total production, and those with higher job turnover export less. Furthermore, relatively high job turnover hinders industry adjustment following trade liberalization. These predictions receive support for U.S. manufacturing industries using turnover data in the Quarterly Workforce Indicators available from the U.S. Census Bureau. (JEL F16)     

TRADE IN POLARIZED AMERICA: THE BORDER EFFECT BETWEEN RED STATES AND BLUE STATES

Political and cultural polarization in the United States is widely discussed, but does it relate to any economic disconnection among states? We estimate the “border” effect between Red and Blue states using the gravity equation with a nonlinear generalized method of moments estimator to simultaneously overcome the problems associated with endogeneity, cross‐state price differences, and zero‐trade flow. The border effect is robustly confirmed for the 2000s, while not so robustly detected for the 1990s. Notably, in 2007, the border reduces trade between Red and Blue states to approximately 75% of the trade within each set of states. This estimated border effect is much smaller than the United States–Canada national border effect estimated by Anderson and van Wincoop (2003), and by Feenstra (2002), yet is comparable to the border effect that Nitsch and Wolf (2009) find for the former West and East Germanies approximately 10 years after reunification. While the border effect in Germany after reunification is decreasing, the border effect between the Red and Blue states is emerging. We also find the border effect is more significant for consumption, rather than intermediate, goods. The border effect is an important indicator for a potential dismantling of the economic connectivity in the United States. (JEL D72, F10, F15, R1)     

THE IMPORTANCE OF TRADE COSTS IN DEVIATIONS FROM THE LAW‐OF‐ONE‐PRICE: ESTIMATES BASED ON THE DIRECTION OF TRADE

The full impact of trade costs in segmenting product markets cannot be captured by considering aggregate prices or in the absence of information on the direction of trade. We address this problem by utilizing product‐specific prices, cross‐sectional productivity indices, and bilateral trade flows, allowing us to identify the probable source of any one product. We show that trade costs in the form of transportation and distribution costs are important in determining international price differences and segmenting international markets. Physical distance relative to the origin has a precisely estimated positive impact on international deviations from the Law‐of‐One‐Price that is larger than estimates that do not account for the origin of each product. Based on our benchmark estimates, the price elasticity of distance was around 10% in 1990. (JEL F4)     

POPULAR SUPPORT FOR TRADE AGREEMENTS AND PARTNER COUNTRY CHARACTERISTICS: EVIDENCE FROM AN UNEXPECTED ELECTION OUTCOME

Using quasi‐experimental data from a survey that was conducted immediately before and after the November 2016 presidential election, we analyze how the election of Donald Trump affected the willingness of Europeans to sign a trade and investment agreement with the United States. We find that the election outcome lead to an immediate and sizable negative effect on Europeans' image of the United States. But we do not find that, at the same time, there was a negative reaction in the willingness of Europeans to sign an agreement with the United States. (JEL F14, F55, C26, F50)     

INTERNATIONAL SUPPLY CHAINS AND THE VOLATILITY OF TRADE

Were the large import fluctuations around the 2007–2009 recession because of increasing trade volatility? I show that import volatility relative to gross domestic product (GDP) increased in the 2000s and examine whether vertical specialization (VS) trade can explain this increase. I develop and calibrate a model of VS trade that generates most of the observed increase in relative import volatility from the 1960s to the 2000s. The increase is because of GDP's shift to less volatile services production. VS trade has a negligible impact. VS causes trade to fall more in recession but also increases the share of output that is traded, leaving volatility unaffected. It increases volatility by shifting trade to more volatile sectors, but this effect is quantitatively small. (JEL E3, F1)     

SENSE AND SURPRISE IN COMPETITIVE TRADE THEORY2010 WEAI PRESIDENTIAL ADDRESS

Economic models are often judged by the reality of their assumptions or their success at predicting realistic outcomes. In this paper I suggest a different criterion for judging models in international trade theory in competitive settings: (i) Does the model conform to common sense in leading to results that even suggest the model is not necessary, and yet (ii) Can the same model be used as a tool to reveal in simple terms why certain outcomes that may appear surprising (often labeled a paradox in trade theory) nonetheless are correct. Many trade theory paradoxes appear as the result of income effects in simple general equilibrium models. Here attention centers instead on two of the familiar production models: the specific factors model and the Heckscher‐Ohlin model, either separately or when combined. It is shown that very basic properties of production underlie many of the surprising results in competitive trade theory. (JEL F11, D50)     

DETERMINANTS OF TRADE AND SPECIALIZATION IN THE ORGANISATION FOR ECONOMIC CO‐OPERATION AND DEVELOPMENT COUNTRIES

This paper empirically investigates the relative importance of productivity, factor endowments, trade costs, and tastes in determining the current pattern of trade and specialization. The results show that productivity and taste differences are the first and second most significant determinants of trade and specialization. Factor endowments are the least influential for the average country in the data set, but their effects are much greater in the poorer than richer countries. The results also show the substantial role of trade costs, which is amplified through interactions with other determinants of trade. Trade costs affect the relative costs of intermediate inputs and final goods, link preferences with specialization, and reduce the geographical range of comparative advantages. (JEL F1, F10)
