This paper develops an elementary theory of global supply chains. We consider a world economy with an arbitrary number of countries, one factor of production, a continuum of intermediate goods, and one final good. Production of the final good is sequential and subject to mistakes. In the unique...

We augment the canonical neoclassical model of trade to allow for interstate disputes over land, oil, water, or other resources. The costs of such disputes in terms of arming depend on the trade regime in place. Under either autarky or free trade, the larger country (in terms of factor...

In this paper, we merge the heterogenous firm trade model of Melitz (2003) with the Ricardian model of Dornbusch, Fisher and Samuelson (DFS 1977) to explain how the pattern of international specialization and trade is determined by the interaction of comparative advantage, economies of scale,...

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...

This paper characterizes the dynamic empirical properties of country export capabilities in order to inform modelling of the long-run behavior of comparative advantage. The starting point for our analysis is two strong empirical regularities in international trade that have previously been...

Introductory economics courses emphasize opportunity cost, comparative advantage and specialization to show the benefits of trade. We assert that this emphasize leads to erroneous student mindset that trade requires specialization based on comparative advantage. We test students who have been...

Over the last millennium, the clan and the corporation have been the loci of cooperation in China and Europe respectively. This paper examines - analytically and historically - the cultural and institutional co-evolution that led to this bifurcation. We highlight that groups with which...

The literature on China indicates that the concentration of economic activities in China is less than in other industrialized countries. Institutional limits are largely held responsible for this finding (e.g. the Hukou system); firms and workers are not able to take full advantage of the...

Latin American countries have lost competitiveness in world markets in comparison to China over the last two decades. The main purpose of this study is to examine the causes of this development. To this end an augmented Ricardian model is estimated using panel data. The explanatory variables...

Do migrants shape the dynamic comparative advantage of their sending and receiving countries? To answer this question we study the drivers of knowledge diffusion by looking at the dynamics of the export basket of countries, with particular focus on migration. The fact that knowledge diffusion...
