We present evidence on the effect of social connections between workers and managers on productivity in the workplace. To evaluate whether the existence of social connections is beneficial to the firm's overall performance, we explore how the effects of social connections vary with the strength...

Using a very large sample of matched author-referee pairs, we examine how the gender of referees and authors affects the former's recommendations. Relying on changing matches of authors and referees, we find no evidence of gender differences among referees in charitableness toward authors; nor...

Politicians can use the public sector to give jobs to cronies, at the expense of the efficiency of those organisations and general welfare. Motivated by a simple model of cronyism that predicts spikes in appointments to state-owned firms near elections, we regress 1980-2008 monthly hirings...

How does factor accumulation affect the pattern of international specialization and returns to capital? We provide a new integrated treatment to this question using a panel of 44 developing and developed countries over the period 1976-2000. We confirm the Heckscher-Ohlin prediction that, with...

This paper examines the role of immigrant networks on trade, particularly through the demand effect. First, we examine the effect of immigration on trade when the immigrants consume more of the goods that are abundant in their home country than the natives in a standard Heckscher-Ohlin model and...

This paper explores the quantitative consequences of transatlantic trade liberalization envisioned in a Transatlantic Trade and Investment Partnership (TTIP) between the United States and the European Union. Our key innovation is to develop a new quantitative spatial trade model and to use an...

This paper highlights that the immigrants' effect on trade is not identical across all types of immigrants but it varies with the immigrants' occupation. Using a sample of 63 U.S. trading partners which are also big immigrant sending countries over the years 1991-2000, this paper finds that the...

Recent research has documented a U-shaped industrial concentration curve over an economy's development path. How far can neoclassical trade theory take us in explaining this pattern? We estimate the production side of the Heckscher-Ohlin model using industry data on 44 developed and developing...

Our paper deals with econometric developments for the estimation of the gravity model which lead to convergent parameter estimates even when a correlation exists between the explanatory variables and the specific unobservable characteristics of each unit. We implement panel data econometric...

This paper studies the impact of outsourcing on individual wages. In contrast to the standard approach in the literature, we focus on domestic outsourcing as well as foreign outsourcing. By using a simple theoretical model, we argue that, if outsourcing is associated with specialization gains...
