Financial liberalization,structural change,and real exchange rate appreciations

The last twenty years have witnessed periods of sustained appreciations of the real exchange rate in emerging economies. The case of Mexico between 1988 and 2002 is representative of several episodes in Latin America and Central and Eastern Europe in which countries opening to capital flows experienced large appreciations accompanied by a significant reallocation of workers towards the non-tradable sector. We account for these facts using a two sector dynamic general equilibrium model of a small open economy with frictions to labor reallocation and two driving forces: (i) A decline in the cost of borrowing in foreign markets, and (ii) differential productivity growth across sectors. These two mechanisms account together for 60% of the decline in the domestic relative price of tradables in Mexico and for a large fraction of the observed reallocation of labor across sectors. The decline in the interest rate faced by Mexico in international markets is quantitatively the most important channel. Our results are robust to the inclusion of terms of trade into the model.     

EXTERNAL SHOCKS AND THE URBAN POOR

This paper examines the effect of external shocks on urban poverty in a two‐household (rich and poor), two‐sector intertemporal model of an open economy with segmented labor markets. Skilled and unskilled labor are used in the formal sector, whereas only unskilled labor (which moves freely across sectors) is used in the informal economy. The extent to which a permanent increase in the world risk‐free interest rate affects the incidence and depth of poverty is shown to depend crucially on the wedge between consumption and product wages. The model is also extended to account for endogenous minimum wages and capital accumulation.     

Volatility due to offshoring: Theory and evidence

Existing models of offshoring are not equipped to explain how global production sharing affects the volatility of economic activity. This paper develops a trade model that can account for why offshoring industries in low wage countries such as Mexico experience fluctuations in employment that are twice as large as in high wage countries such as the United States. We argue that a key to explaining this outcome is that the extensive margin of offshoring responds endogenously to shocks in demand and transmits those shocks across borders in an amplified manner. Empirical evidence supports the claim that the extensive margin of offshoring is an active margin of adjustment, and quantitative simulation experiments show that the degree of movement of this margin in the data is sufficient to explain relative employment volatility in Mexico and the U.S.     

Sovereign debt crises and credit to the private sector

We use micro-level data to analyze emerging markets' private sector access to international debt markets during sovereign debt crises. We find that these crises are systematically accompanied by a decline in foreign credit to domestic private firms, both during debt renegotiations and for over two years after restructuring agreements are reached. This decline is large, statistically significant, and robust. We find that this effect is concentrated in the non-financial sector and is different for firms in the exporting and in the non-exporting sectors. We also find that the magnitude of the effect depends on the type of debt restructuring agreement.     

Does services liberalization benefit manufacturing firms?: Evidence from the Czech Republic

While there is considerable empirical evidence on the impact of liberalizing trade in goods, the effects of services liberalization have not been empirically established. This study examines the link between services sector reforms and the productivity of manufacturing industries relying on services inputs. Several aspects of services liberalization are considered, namely, the presence of foreign providers, privatization and the level of competition. The results, based on firm-level data from the Czech Republic, show a positive relationship between services sector reform and the performance of domestic firms in downstream manufacturing sectors. Allowing foreign entry into services industries appears to be the key channel through which services liberalization contributes to improved performance of manufacturing sectors. This finding is supported by evidence that foreign acquisitions of Czech services providers result in profound changes in the labor productivity and sales of acquired firms. As most barriers to foreign investment today are not in goods but in services sectors, the findings of this study may strengthen the argument for reform in this area.     

Do interest groups affect US immigration policy?

While anecdotal evidence suggests that interest groups play a key role in shaping immigration policy, there is no systematic empirical analysis of this issue. In this paper, we construct an industry-level dataset for the United States, by combining information on the number of temporary work visas with data on lobbying activity associated with immigration. We find robust evidence that both pro- and anti-immigration interest groups play a statistically significant and economically relevant role in shaping migration policy across sectors. Barriers to migration are lower in sectors in which business interest groups incur larger lobbying expenditures and higher in sectors where labor unions are more important.     

Tariff wars in the Ricardian Model with a continuum of goods

This paper describes strategic tariff choices within the Ricardian framework of Dornbusch, Fischer, and Samuelson (1977) using CES preferences. The optimum tariff schedule is uniform across goods and inversely related to the import demand elasticity of the other country. In the Nash equilibrium of tariffs, larger economies apply higher tariff rates. Productivity adjusted relative size (≈ GDP ratio) is a sufficient statistic for absolute productivity advantage and the size of the labor force. Both countries apply higher tariff rates if specialization gains from comparative advantage are high and transportation cost is low. A sufficiently large economy prefers the inefficient Nash equilibrium in tariffs over free trade due to its quasi-monopolistic power on world markets. The required threshold size is increasing in comparative advantage and decreasing in transportation cost. I discuss the implications of the static Nash-equilibrium analysis for the sustainability and structure of trade agreements.     

The impact of trade liberalization on productivity: Evidence from India's formal and informal manufacturing sectors

Despite a large literature investigating the impacts of trade on firm productivity, there is almost no evidence on how small firms react to trade liberalization. Using a unique dataset of firm-level surveys that are representative of the entire Indian manufacturing industry, I show that India's unilateral reduction in final goods tariffs increased the average productivity of small, informal firms, which account for 80% of Indian manufacturing employment but have been excluded from previous studies. In contrast, the increase in productivity among larger, formal firms was driven primarily by the concurrent reduction in input tariffs. By examining the effect of the tariff liberalization on the distributions of productivity and firm size, I find evidence consistent with the exit of the smallest, least productive firms from the informal sector. In addition, I find that although the decline in final goods tariffs did not significantly impact average formal sector productivity, it did increase productivity among the top quantiles of the distribution.     

Exchange rate fluctuations and quality composition of exports: Evidence from Swiss product-level data

This paper studies the relationship between exchange rate movements and the average export quality using disaggregated Swiss product-level data between 1996 and 2015. We find evidence at different levels of aggregation that the average export quality increases in response to a currency appreciation through compositional effects: currency appreciations shift market shares towards goods that are more expensive and of higher quality. This exchange rate effect on quality is more pronounced for differentiated goods and in sectors with a greater scope for quality differentiation. From a policy perspective, this reallocation effect points to the importance of facilitating structural changes in the export composition to increase the resilience of the export sector to exchange rate shocks. Our results also suggest a positive relationship between the average export quality and aggregate export sales. From a methodological point of view, the findings imply that exchange rate pass-through estimations without quality controls tend to be biased regardless of aggregation level or type of data.     

Trade liberalization and the allocation of labor between households and markets in a poor country

We consider the relationship between relative price changes and the allocation of labor between households and the formal wage labor market in the context of Vietnam's liberalization of its rice trade in the 1990s. Many individuals in poor economies work within their own household rather than in formal labor markets. We find that larger rice price increases in a community are associated with declines in hours adults devote to work within the household and increases in time spent in the wage labor market. We also observe increased specialization in household economic activities accompanying these shifts in hours towards wage work. Our results are consistent with the idea that a growth in the extent of the market shifts production and labor from households to markets during development, thereby inducing gains from specialization. Thus, the reallocation of labor between households and markets in response to a trade liberalization might be an important component in understanding the link between trade and growth in very poor economies, currently the focus of the Doha WTO negotiation round.     

Immigration and structural change: Evidence from post-war Germany

Does immigration accelerate sectoral change from low- to high-productivity sectors? This paper analyzes the effect of one of the largest population movements in history, the influx of millions of German expellees to West Germany after World War II, on Germany's speed of transition away from low-productivity agriculture. A simple two-sector specific factor model, in which moving costs prevent the marginal product of labor to be equalized across sectors, predicts that expellee inflows boost output per worker by expanding the high-productivity non-agricultural sector but decrease output per worker within sectors. Using German district-level data from before and after the war, we find empirical support for these predictions.     

Trade liberalization and the evolution of skill earnings differentials in Brazil

Skilled labor earnings differentials decreased during the trade liberalization implemented in Brazil from 1988 to 1995. This paper investigates the role of trade liberalization in explaining these relative earnings movements. We perform several independent empirical exercises that check the traditional trade transmission mechanism, using disaggregated data on tariffs, prices, earnings, employment and skill intensity. We find that: i) employment shifted from skilled to unskilled intensive sectors, and each sector increased its relative share of skilled labor; ii) relative prices fell in skill-intensive sectors; iii) tariff changes across sectors were not related to skill intensities, but the pass-through from tariffs to prices was larger in skill-intensive sectors; iv) the decline in skilled earnings differentials mandated by the price variation predicted by trade was even larger than the observed one. The results are compatible with trade liberalization accounting for the observed relative earnings changes in Brazil. They also highlight the importance of considering the effects of differentiated pass-through from tariffs to prices.     

Job creation, job destruction, and the real exchange rate

Welfare gains from trade are reduced by adjustment costs associated with factor reallocation, but most studies of the effects of trade on labor markets focus only on net employment change. This paper takes a step toward identifying trade-related adjustment costs by estimating the effects of real exchange rates on labor reallocation using a new model of gross job creation and destruction applied to detailed U.S. manufacturing industries between 1973 and 1993. Trend real exchange rates significantly affect job reallocation but not net employment. Cyclical real exchange rates significantly affect net employment through job destruction only.     

Estimating vertical spillovers from FDI: Why results vary and what the true effect is

In the last decade, more than 100 researchers have examined productivity spillovers from foreign affiliates to local firms in upstream or downstream sectors. Yet results vary broadly across methods and countries. To examine these vertical spillovers in a systematic way, we collected 3626 estimates of spillovers and reviewed the literature quantitatively. Our meta-analysis indicates that model misspecifications reduce the reported estimates and journals select relatively large estimates for publication. No selection, however, was found for working papers. Taking these biases into consideration, the average spillover to suppliers is economically significant, whereas the spillover to buyers is statistically significant but small. Greater spillovers are received by countries that have underdeveloped financial systems and are open to international trade. Greater spillovers are generated by investors who come from distant countries and have only a slight technological edge over local firms.     

On the origins of comparative advantage

This paper proposes a simple theory of international trade with endogenous productivity differences across countries. The core of our analysis lies in the determinants of the division of labor. We consider a world economy comprising two large countries, with a continuum of goods and one factor of production, labor. Each good is characterized by its complexity, defined as the number of tasks that must be performed to produce one unit. There are increasing returns to scale in the performance of each task, which creates gains from specialization, and uncertainty in the enforcement of each contract, which create transaction costs. The trade-off between these two forces pins down the size of productive teams across sectors in each country. Under free trade, the country where teams are larger specializes in the more complex goods. In our model, it is the country where the product of institutional quality and human per worker capital is larger. Hence, better institutions and more educated workers are complementary sources of comparative advantage in the more complex industries.     

Agricultural productivity differences and credit market imperfections

This paper presents a simple model to examine the implication of credit market imperfections when considering the huge variation of agricultural labor productivity across countries. The development of credit markets enables more agents to acquire skills to work in non-agricultural sectors. The expansion of the sectors decreases the labor supply to agriculture as well as increases the supply of modern intermediate inputs to agriculture. Agricultural producers accordingly substitute the relatively cheap intermediate inputs for labor to produce a given level of an agricultural good, and, thereby, the output per worker in agriculture is improved. Poor countries with less developed credit markets are, therefore, far less productive in agriculture than rich countries with well-developed credit markets.     

Exporting out of poverty: Provincial poverty in Vietnam and U.S. market access

Can a developing country reduce poverty by gaining increased market access to a large, rich country? The 2001 U.S.–Vietnam Bilateral Trade Agreement (BTA) provides an excellent opportunity to examine this question as, unlike other bilateral trade agreements, the U.S. tariff cuts were not influenced by Vietnamese industries. Using variation in the structure of the labor force across provinces prior to the trade agreement, I construct provincial measures of U.S. tariffs. To address concerns over confounding trends between changes in provincial poverty and changes in provincial tariffs I follow two approaches: controlling for trends based on observable initial conditions and differencing away time invariant trends using pre-BTA data. I find that provinces that were more exposed to the U.S. tariff cuts experienced faster decreases in poverty between 2002 and 2004. Additionally, I document that the movement of workers across provinces is limited in scale, particularly for those with low levels of education. Finally, I show that the most exposed provinces experienced faster wage growth for workers with low levels of education, but not for highly educated workers.     

Habit formation and fiscal transmission in open economies

In this paper we analyze the ability of an open economy version of the neoclassical model to account for the time-series evidence on fiscal policy transmission. Revisiting the evidence, we find that i) government spending raises output, while inducing a simultaneous decline of investment and the current account and ii) the responses of output and investment are more muted in more open economies while current account deficits tend to be larger. Turning to the model, we explore the role of habit formation for fiscal policy transmission. Specifically, we show that the model can account for the evidence if consumption behavior is characterized by habit formation and the terms of trade adjust endogenously.     

The role of FDI in structural change: Evidence from Mexico

Foreign direct investment (FDI) flows to Mexico are substantial and play an important role in the Mexican economy since the mid-1990s. These investments reflect the activities of multinational firms that shape to some extent the economic landscape and sectoral structure in this host country. We illustrate that there is considerable variation in the amounts of FDI and structural change within the country and across time. Based on this, the paper's main purpose is to analyse whether there is a significant impact of FDI on structural change. We conduct an empirical analysis covering the period 2006–16. We use the fixed-effects estimator where the unit of observation is a Mexican state for which we calculate structural change from the reallocation of labour between sectors. The results suggest that (if any) there is a positive effect from FDI on growth-enhancing structural change. This effect depends critically on the lag structure of FDI. Moreover, there is some evidence that the positive effect (a) arises from FDI flows in the industry sector and (b) is present for medium and low-skilled labour reallocation.     

Power laws in firm size and openness to trade: Measurement and implications

Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in absolute value than the power law exponent among non-exporting firms. We use a dataset of French firms to demonstrate that this prediction is strongly supported by the data, both for the economy as a whole and at the industry level. Furthermore, the differences between power law coefficients for exporters and non-exporters are larger in sectors that are more open to trade. While estimates of power law exponents have been used to pin down parameters in theoretical and quantitative models, our analysis implies that the existing estimates are systematically lower than the true values. We propose two simple ways of estimating power law parameters that take explicit account of exporting behavior.
