We develop a two-sector, two-country model where trade is driven by technological differences. Each country is populated by large number of heterogeneous workers distinguished by their level of skills. Given that one country has a technological advantage in the skilled intensive good when we...

We develop a dynamic computational network model of the banking system where fire sales provide the amplification mechanism of financial shocks. Each period a finite number of banks offers a large, but finite, number of loans to households. Banks with excess liquidity also offer loans to other...

This paper provides a unified framework for endogenizing two distinct organizational structures of financial intermediation. In one structure, called Bank, the intermediary is financed by issuing debt contracts to investors, and thus resembles commercial banks. In the other structure, called...

We develop a two-country, two-sector model of trade where the only difference between the two countries is their distribution of human capital endowments. We show that even if the two countries have identical aggregate endowments the pattern of trade depends on the properties of the two human...

The empirical evidence suggests that while small firms in United States, United Kingdom and Canada rely on internal funds for financing R&D, similar firms in Japan, Germany and France have access to bank loans. In this paper, we analyze the financial decisions of small firms willing to invest in...

Charitable giving increasingly requires recipients to undertake costly prior action. A common justification is that willingness to undertake costly actions signals greater productivity from transfers. We demonstrate that, if the distribution of recipient types is unknown, recipient costs...

We develop and analyze an entry model that predicts that the likelihood that foreign firms enter a country increases with the productivity gap between foreign and domestic firms. The intuition is that foreign firms locate where their competitive advantage is highest and thus enter countries...
