Trade policy and wage inequality : a structural analysis with occupational and sectoral mobility

A number of authors have argued that a workers occupation of employment is at least as important as the workers industry of employment in determining whether the worker will be hurt or helped by international trade. This paper investigates the role of occupational mobility on the effects of trade shocks on wage inequality in a dynamic, structural econometric model of worker adjustment. Each worker in the model can switch either industry, occupation, or both, paying a time-varying cost to do so in a rational-expectations optimizing environment. The authors find that the costs of switching industry and occupation are both high, and of similar magnitude, but in simulations they find that a workers industry of employment is much more important than either the workers occupation or skill class in determining whether he or she is harmed by a trade shock.

Some Simple Analytics of Trade and Labor Mobility

We study a simple, tractable model of labor adjustment in a trade model that allows us to analyze the economys dynamic response to trade liberalization. Since it is a neoclassical market-clearing model, we can use duality techniques to study the equilibrium, and despite its simplicity a rich variety of properties emerge. The model generates gross flows of labor across industries, even in the steady state; persistent wage differentials across industries; gradual adjustment to a liberalization; and anticipatory adjustment to a pre-announced liberalization. Pre-announcement makes liberalization less attractive to export-sector workers and more attractive to import-sector workers, eventually making workers unanimous either in favor of or in opposition to liberalization. Based on these results, we identify many pitfalls to conventional methods of empirical study of trade liberalization that are based on static models.

Provision of Liquidity through the Primary Credit Facility during the Financial Crisis: A Structural Analysis

Over the course of the recent liquidity crisis, the Federal Reserve made several changes to its primary credit lending facility such as narrowing the spread between the primary credit rate and the target funds rate and increasing the term of the borrowing. In this paper, we use the model developed by Artuc and Demiralp (2008) to provide a structural assessment of the effectiveness of these changes. Our results suggest that these changes were effective in stabilizing the federal funds market.

Workers'Age and the Impact of Trade Shocks

Do trade shocks affect workers differently because of their age? This paper examines the issue by estimating the lifetime mobility of workers based on the sectors in which they work. Using U.S. data, the paper shows that mobility costs rise with a workers age and years of experience, but stay the same regardless of his or her education level. In addition, using a general-equilibrium simulation of counterfactual trade-liberalization policies in the metal manufacturing sector, the paper shows that trade shocks affect workers with higher mobility costs more, for both winners and losers of the policy shocks. But the effects taper off over a workers lifetime, especially when they are close to retirement.

The Rise of China and Labor Market Adjustments in Latin America

This paper assesses the impact of the rise of China on the trade of Latin American and Caribbean economies. The study proposes an index to measure the impact on trade, which suggests sizable effects, especially in Argentina, Brazil, Chile, Honduras, Mexico, and Paraguay. The paper uses the index and a model of labor mobility, to calculate the impact of Chinas growth on labor markets in Argentina, Brazil, and Mexico. The resulting evidence suggests that the rise of China has had positive effects on agriculture and mining in Argentina and Brazil, which offset negative impacts on manufacturing industries, thus leaving total employment and real wages virtually unchanged in the long run. In contrast, the estimated impacts of Chinas rise on Mexico imply that the sizable shock to manufacturing was not offset by the positive shocks on mining and agriculture, reducing employment in the long run. The paper also discusses the effect of China on the degree of informality in these three economies and contrasts short-run and long-run effects on employment and wages across industries.

Transit migration : all roads lead to America

The paths of many migrants include multiple destinations and transit routes, yet this pattern is almost never reflected in empirical analyses. For example, 9 percent of recent immigrants to the United States arrived from a transit country as opposed to the country where they were born. Among those arriving from many high-income countries, the transit migration ratio exceeds 30 percent. To explain these patterns, this paper constructs a dynamic model of global migration that allows transit migration opportunities to impact the attractiveness of locations. After estimating the structural parameters of the model, the paper simulates various counterfactual scenarios to highlight the spillovers of transit migration paths.

Export performance and geography in Croatia

This paper uses the gravity model to analyze whether the varying export performance of Croatian counties can be explained by their proximity to border gates, ports, and other county-specific characteristics. The analysis finds that longer distances to border gates increase trade frictions significantly for many product categories, although these frictions have been decreasing between 2007 and 2012. The paper analyzes the county specific factors that are associated with variation in export performance, net of distance. Results show that exports are strongly and positively correlated with motorway and road density, the size of the labor force, low-skill ratio, and the number of patents. These variables are also associated with a greater diversity of exports in terms of products and destinations. Several general policy implications are highlighted. The significant association between motorway and road density and export volume, number of destinations, as well as the diversity of exported products may indicate that improvements in connectivity and facilitation of transport could still play a significant role in enhancing regional trade outcomes. Similarly, good performance in research and development may significantly help to spur competitiveness and allow local producers to enter new markets in products and destinations, which in turn can increase the level of diversification and boost resilience to global economic shocks.
