The world trade collapsed in the most recent recession. Some analysts have suggested the increasing offshoring of the supply chain, or vertical specialization (VS) trade, can explain the apparent increase in volatility of trade over the business cycle. This paper develops a model of VS trade to examine its impact on the volatility of trade. The model features increased trade volatility as VS tr...

Trade costs have fallen surprisingly little given the large increase in international trade in the last 50 years. This paper examines whether trade costs are properly measured. I show theoretically that trade weighted measures will underestimate the changes in trade costs when there are fixed market entry costs and quality differences. Newly traded goods enter at higher trade costs than previou...

 Libya experienced a substantial increase in oil revenue as a result of increased oil prices during the period of the late 1970s and early 1980s, and again after 2000. Recent increases in oil production and the price of oil, and their positive and negative macroeconomic impacts upon key macroeconomic variables, are of considerable contemporary importance to an oil dependent economy such as that...

This paper provides empirical evidence for the interaction between firm-level total factor productivity and trade liberalization as key determinants of firm-level job destruction caused by trade. We also test some key theoretical predictions from Melitz (2003), whose model is used to derive an explicit equation relating firm productivity and trade-induced labor layoff when a country liberalizes...

Workers’ Views of the Impact of Trade on Jobs Although public policy is influenced by the perception that workers worry about the impact of trade on their jobs, there is little empirical evidence on what shapes such views. This paper uses new data to examine how workers’ perceptions of the impact of trade are related to their career paths, job characteristics, and local labor market conditions....

Corporate organization varies within countries and between countries. We develop a theory which explains the variation in levels of decentralization across firms and links it to the trade environment that firms face. We introduce firms with internal hierarchies in a Melitz and Ottaviano (2008) model of international trade. We show that international trade increases the conflict of interest betw...

To examine the effects of unilateral trade liberalization on growth and welfare of the liberalizing and partner countries through intraindustry reallocations, we formulate an asymmetric two-country Melitz model of trade and endogenous growth based on capital accumulation. We obtain two main results. First, each country’s mass of exported varieties, revenue share of exported varieties, and growt...

Nineteen recent studies have investigated the effect of currency union on trade, resulting in 383 point estimates of the effect. This paper is a quantitative attempt to summarize the current state of debate; meta-analysis is used to combine the disparate estimates. The chief findings are that: a) the hypothesis that there is no effect of currency union on trade can be rejected at standard signi...
