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 small, open economy, two-sector model with heterogeneous agents and endogenous participation in a labor matching market. We analyze the implications of asymmetric market entry costs for the patterns of international trade and underemployment. Furthermore, we examine the welfare...

Traditionally banks have used securitization for expanding credit and thus their profitability. It has been well documented that, at least before the 2008 crisis, many banks were keeping a high proportion of the securities that they created on their own balance-sheets. Those securities retained...

We consider the optimal education policies of a small economy whose government has a limited budget. Initially, the economy is closed and the government chooses its education policy to maximize welfare under autarky. Then the economy trades with the rest of the world. Lastly, the government...

A common practice of banks has been to pool assets of different qualities and then sell a fraction of the newly created portfolios to investors. We extend the signaling model for single sales of risky assets to portfolio sales. We identify conditions under which signaling at the portfolio level...

We study the formation of networks in environments where agents derive benefits from other agents directly linked to them but suffer losses through contagion when any agent on a path connected to them is hit by a shock. We first consider networks with undirected links (e.g. epidemics,...

We introduce financial frictions into a simple two sector model of international trade with heterogeneous agents and investigate the impact of differences in the strength of financial institutions and wealth inequality on trade flows, capital movements and entrepreneurial migration. Distinct...

In this paper we review recent advances in financial economics in relation to the measurement of systemic risk. We start by reviewing studies that apply traditional measures of risk to financial institutions. However, the main focus of the review is on studies that use network analysis paying...

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...

Countries differ on the extent to which their financial system relies on banks or on the financial market. We offer a model featuring a possible two way relationship between countries' financial system architecture and their comparative advantage. Countries specialising in bank dependent sectors...
