We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...

This paper introduces the theory of firm organization under moral hazard into an equilibrium model of international trade with heterogeneous talents and technologies. The model is able to explain how the allocation of power and the provision of financial incentives inside firms varies within and...

How shifts in the economic leadership between countries can occur has been widely debated not only since the recent catch up of China in several sectors. However, there is no adequate theoretical model analyzing this question in the light of trade liberalization. This paper is the first one to...

This paper sets up a heterogeneous firms model, where production consists of a continuum of tasks that differ in complexity. Firms hire low-skilled and high-skilled workers to perform these tasks. How firms assign workers to tasks depends on factor prices for the two skill types and the...

We use Spanish firm-level data to test the hold-up model of global sourcing proposed by Antr s & Helpman (2004). We propose a novel representation of the model which guides us in bringing the theory to the data. We estimate a discrete choice model of firms' sourcing behavior, separately for the...

We set up a two-country general equilibrium model, in which heterogeneous firms from one country (the source country) can offshore routine tasks to a low-wage host country. The most productive firms self-select into offshoring, and the impact on welfare in the source country can be positive or...

Legalized parallel trade implies that an original manufacturer cannot control a retailer in a foreign country once the latter has ordered its sales quantity and has compensated the former. This paper endogenizes the role of the retailer as an agent who has private information on the perceived...

We incorporate trade in tasks l a Grossman and Rossi-Hansberg (2008) into the international trade theory of fi rm organization of Marin and Verdier (2012) to examine how off shoring affects the way firms organize. We test the predictions of the model based on firm level data of 660 Austrian and...

Krugman's (1979, 1980) monoplistic competition model of trade showed that countries with more similar per-capita GDP trade more with each other. Does this mean that developing countries shift trade towards developed countries as a result of high economic growth? The results reported in this...

On 23rd February 2017, SUERF and EY organized a conference on "Brexit and the Implications for Financial Services" at EY's offices, Churchill Place, Canary Wharf, London. While the outcome of the Brexit negotiations remains highly uncertain, the conference discussed the burning questions for...
