Increasing-returns-to-scale imperfect competition trade models predict a more than proportionate relationship between the larger country’s share in world endowments and its share in producing firms: the so called home market effect (HME). While this result plays a key role in empirical...

This paper characterizes analytically the optimal tariff of a large one-sector economy with monopolistic competition and firm heterogeneity in general equilibrium, thereby extending the small-country results of Demidova and Rodriguez-Clare (JIE, 2009) and the homogeneous firms framework of Gros...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

Recent trade theory in the Krugman (1980) tradition predicts that countries with larger market size enjoy higher levels of total factor productivity (TFP) – and equivalently of real per capita income or welfare – as a smaller fraction of spending on inputs is affected by trade costs....

We develop a theoretical framework to explain firms' offshoring decisions in the presence of uncertainty. This model highlights the role of labor market institutions in shaping a firm's ability to effectively react upon future shocks, yielding a sharp prediction of the prevalence of offshoring...

We show that in a Ricardo-Viner-type trade model with unemployment due to search and matching the productivity effect of offshoring emphasized by Grossman & Rossi-Hansberg (2008) emerges as a vehicle of job creation. Improvements in the technology of offshoring causes job losses at the extensive...

We investigate the link between productivity of firms and their sourcing behavior. Following Antràs & Helpman (2004) we distinguish between domestic and foreign sourcing, as well as between outsourcing and vertical integration. A firm's choice is driven by a hold-up problem caused by lack of...
