This paper develops a two-sector, two-factor trade model with labor market frictions in which workers search for a job also when they are employed. On the job search (OJS) is a key ingredient to explain the response to trade liberalization of sectoral employment, unemployment and wage...

There have been significant improvements in traditional trade policies in the past few decades. However, these improvements can only be fully effective when they are complemented with a favorable investment climate. This study focuses on a particular aspect of investment climate, namely labor...

The Stolper-Samuelson theorem predicts the relative wage of high-skilled labor will increase in the U.S. but decrease in Mexico after trade, while data shows the skill premium began to rise in both countries during the 1980s. This paper presents a simple trade-based resolution of this “wage...

This report critically analyses the paper "A Simple Model of Firm Heterogeneity, International Trade and Wages' authored by, Stephen Ross Yeaple. Yeaple (2005) introduces a static model in which ex-ante homogeneous firms are differentiated based on heterogeneity in technology adoption and skill...

Adam Smith (1776) devoted the first three chapters to the division of labor in his Inquiry into the Nature and Causes of the Wealth of Nations. This process, carried far enough, eventually results in a divergence between the distributions of supplies and demands of such...

This paper addresses the impact of FDI on the labor share of income in developing countries. We propose a theory that relies on the impacts of FDI on productive heterogeneity between firms in a frictional labor market. We argue that FDI have two opposite effects on the labor share: a negative...

This paper proposes a trade model with heterogeneous firms that decide not just whether and how much to export but also whether and how much to innovate. Incorporating both the extensive and intensive margins of trade and innovation leads to different possible equilibria. Depending on how costly...

We present an international trade model with multiproduct firms. Firms are heterogeneously endowed with two types of capabilities that jointly determine the trade-off within firms between managing a large portfolio of products and producing at low marginal cost. The model can explain many of the...

This paper develops a theory which investigates how firms’ choice of corporate organization is affecting firm performance and the nature of competition in international markets. We develop a model in which firms’ organisational choices determine heterogeneity across firms in size...

We develop a model of international trade with two sources of firm heterogeneity: "productivity" and "caliber". Productivity is modeled as is standard in the literature. Caliber is the ability to produce quality using few fixed inputs. While there is no quality restriction to sell domestically,...
