Firm dynamics, job turnover, and wage distributions in an open economy

This paper explores the effects of tariffs, trade costs, and firing costs on firm dynamics and labor markets outcomes. The analysis is based on a general equilibrium model with labor market search frictions, wage bargaining, firing costs, firm-specific productivity shocks, and endogenous entry/exit decisions. Firing costs reduce firms' profits and discourage them from quickly adjusting their employment levels in response to idiosyncratic shocks. Tariffs and other trade costs reduce rents for efficient firms and increase rents for inefficient firms, as in Melitz (2003). These well-known effects interact with idiosyncratic productivity shocks and with scale economies in hiring costs to determine the equilibrium size distribution of firms, entry/exit rates, job turnover rates, rate of informality, and cross-firm wage distributions.

Domestic Road Infrastructure and International Trade: Evidence from Turkey

Poor domestic transportation infrastructure in developing countries is often cited as an important impediment for accessing international markets. Yet, evidence on how transportation infrastructure improvements affect the volume and composition of exports is scarce. Drawing on the large-scale public investment in expressways undertaken in Turkey during the 2000s, this paper contributes to our understanding of how internal trade costs affect regional exports and specialization. Two results emerge. First, we estimate that this road infrastructure project accounts for 15 percent of the export increase from interior regions, generating a 10-year discounted stream of additional export revenues that amount to between 9 and 14 percent of the value of the investment. Second, while the exports of all industries within a given region increase in response to improvements in connectivity to the international gateways of the country, the magnitude of this increase is larger the more time sensitive an industry is. Accordingly, we also observe an increase in the regional employment and revenue shares of such industries. Our results support the hypothesis that internal trade costs can be a determinant of international specialization and comparative advantage

Firm Dynamics, Job Turnover, and Wage Distributions in an Open Economy

This paper explores the combined effects of reductions in trade frictions, tariffs, and firing costs on firm dynamics, job turnover, and wage distributions. It uses establishment-level data from Colombia to estimate an open economy dynamic model that links trade to job flows in a new way. The fitted model captures key features of Colombian firm dynamics and labor market outcomes, as well changes in these features during the past 25 years. Counterfactual experiments imply that integration with global product markets has increased both average income and job turnover in Colombia. In contrast, the experiments find little role for this country's labor market reforms in driving these variables. The results speak more generally to the effects of globalization on labor markets in Latin America and elsewhere.
