We model home country familiarity with business opportunities in a foreign country as a parameter in a matching process between domestic and foreign firms. We show that as familiarity increases the effect of relative national labor supplies on relative national wages declines, the elasticity of...

Conventional wisdom has it that global financial markets were as well integrated in the 1890s as in the 1990s, but that it took several post-war decades to regenerate the connections that existed before 1914. This view has emerged from a variety of tests for world financial capital market...

In this article, we examine the effect of the imperfect mobility of goods on international risk sharing and, through that, on the investment in risky projects, welfare and growth. We find that the welfare gain of financial market openness is not monotonic with respect to investors' risk aversion...

Globalization -- the integration of national economies -- has become one of the most widely used buzzwords of the late 20th century. Yet there are remarkably few statistical measures of product-market integration across time, countries, and goods. In this paper we present some new measures of...

We use a temporary ban on inter-province shipping of live hogs induced by the 2018 outbreak of African Swine Fever (ASF) in China as a natural experiment to study spatial mechanisms behind the dynamics of market integration. With a unique dataset of weekly provincial hog prices, we employ a...

Effective and economical expansion of renewable energy is one of the most urgent and important challenges of addressing climate change. However, many countries are facing a problem because existing network infrastructures (i.e., transmission networks) were not originally built to accommodate...

How does financial integration impact capital accumulation, current-account dynamics, and cross-country inequality? We investigate this question within a two-country, general-equilibrium, incomplete-markets model that focuses on the importance of idiosyncratic entrepreneurial risk-- a risk that...

At a time of historic challenges to the viability of the Eurozone, we assess the contribution of the EU and the Euro to equity market integration in Europe. We use a simple and essentially model free measure of bilateral market segmentation: two countries are segmented if there is a wide...

This paper develops a simple model of international trade with intermediation. We consider an economy with two islands and two types of agents, farmers and traders. Farmers can produce two goods, but in order to sell these goods in centralized (Walrasian) markets, they need to be matched with a...

This paper provides a general framework for analyzing the optimal degree and form of financial integration. Full integration is not in general optimal: faced with a choice between two polar regimes, full integration or autarky, autarky may be superior. The intuition is simple: if underlying...
