We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

"We present a dynamic two-region model with overlapping generations. There are two types of public expenditure, education and infrastructure funding, and governments decide optimally on budget size (tax rate) and its allocation across the two outlays. Productivity of government infrastructure...

We use disaggregated data on Chilean plants, and the Chilean input-output table to examine the impact of agglomeration spillovers on total factor productivity (TFP). In common with previous studies, we find evidence of intra-industry spillovers, but no evidence of cross-industry spillovers in...

In this paper, we explore the impact of part-time work on firm productivity. Using a large panel data set of Italian corporations' balance sheets for the period 2000-2010, we first estimate the total factor productivity (TFP) of each firm for each year. We use different approaches aimed at...

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a novel framework to address this question at three...

Using comprehensive data for German establishments (1999-2008), we estimate plant-level production functions to analyze if "cultural diversity" affects total factor productivity. We distinguish diversity in the establishment's workforce and in the aggregate regional labor force where the plant...

In this paper, we explore the impact of workers' tenure on firm productivity, using rich longitudinal matched employer-employee data on private Belgian firms. We estimate a production function augmented with a firm-level measure of tenure. We deal with endogeneity, which arises from unobserved...

We investigate the impact of sickness absenteeism on productivity by using rich longitudinal matched employer-employee data on Belgian private firms. We deal with endogeneity, which arises from unobserved firm heterogeneity and reverse causality, by applying a modified version of the Ackerberg...
