In this paper, we construct an elaborate general equilibrium model with a continuum of production fragments for an intermediate good, then embed it in a growth model to address the effects of global production fragmentation, vertical specialization and trade on growth and inequality for a small...

The COVID-19 pandemic has had a dramatic impact on families’ lives, with parents all over the world struggling to meet the increased demands of housework, childcare and home-schooling. Much of the additional burden has been shouldered by women, particularly in countries with a traditionally...

Following Garicano (2000), we consider groups whose members decide what knowledge to acquire and how to use this knowledge in production. If efficient production requires common knowledge, all group members should become workers and acquire common knowledge. But if efficient production requires...

This paper investigates the effects on firms' occupational structure of shocks induced by the introduction of Technical Barriers to Trade (TBTs) in importing countries. We rely on the Specific Trade Concern (STC) data released by the WTO to identify trade-restrictive TBT measures, combined with...

We investigate the dimensions through which R&D spillovers are propagated across firms via cooperation through Research Joint Ventures (RJVs). We build on the framework developed by Bloom et al. (2013) which considers the opposing effects of technology spillovers and product market rivalry, and...

Does access to information and communication technologies (ICT) increase innovation? We examine this question by exploiting the staggered adoption of BITNET across U.S. universities in the 1980s. BITNET, an early version of the Internet, enabled e-mail-based knowledge exchange and collaboration...

Germany exhibits a strong reduction in domestic manufacturing production depth (bazaar effect). I argue that this reflects an unbundling of comparative advantage. Using a model where Ricardian plus Heckscher-Ohlin-type comparative advantage relates to fragments of production, I compare a trading...

The paper examines of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organisation away from the traditional functional departments and towards multi-tasking and job rotation. Whereas the exsisting literature on the division of labour...

We propose a quantitative framework for the analysis of industrialization in which specialization in manufacturing or agriculture is driven by comparative advantage and non-homothetic preferences. Countries are integrated through trade but trade is not costless and geographic position matters....
