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 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 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...

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 introduce financial frictions in a two sector model of international trade with heterogeneous agents. The level of specialization in the economy (economic development) depends on the quality of financial institutions. Underdeveloped financial markets prohibit an economy to specialize in...

We develop a two-country, two-sector model with a continuum of workers to address the link between migration and trade where policy is determined by a simple referendum. In particular, we address two questions. First, are states already in free trade areas more likely to support full integration...

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...

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...

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...

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...
