Systemic risk in banking, fire sales, and macroeconomic disasters (2024)
Journal Article
Bougheas, S., Harvey, D. I., Kirman, A., & Nelson, D. (2024). Systemic risk in banking, fire sales, and macroeconomic disasters. Journal of Economic Dynamics and Control, 168, Article 104975. https://doi.org/10.1016/j.jedc.2024.104975

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 wit... Read More about Systemic risk in banking, fire sales, and macroeconomic disasters.

Dynamic Investigations of an Endogenous Business Cycle Model with Heterogeneous Agents (2023)
Journal Article

We introduce agents'heterogeneity into a model of endogenous business cycles, in which agents can invest either in 'good'projects that contribute to future capital formation, or in 'bad' projects without that property. The resulting map involves thre... Read More about Dynamic Investigations of an Endogenous Business Cycle Model with Heterogeneous Agents.

Contagion in networks: Stability and efficiency (2021)
Journal Article

We study the formation of networks in environments where agents derive benefits from their neighbours (immediate links) but suffer losses through contagion when any agent on a path that connects them is hit by a shock. We first consider networks with... Read More about Contagion in networks: Stability and efficiency.

A Theory of Outside Equity: Financing Multiple Projects (2021)
Journal Article

In the financial economics literature debt contracts provide optimal solutions for addressing managerial moral hazard problems. We analyze a model with multiple projects where the manager obtains private information about their quality after the cont... Read More about A Theory of Outside Equity: Financing Multiple Projects.

Countries differ in the extent to which their financial systems rely on banks or on financial markets. We offer a model featuring a complex relationship between countries’ financial system architecture and their comparative advantage. Countries with...

Portfolio sales and signaling (2018)
Journal Article

This paper extends the DeMarzo and Duffie (1999) signaling model from single sales to portfolio sales. It shows that the extended model can account for retention of low quality assets and help explain why retained assets may be of varying quality.

Foreign currency borrowing, exports and firm performance: evidence from a currency crisis (2018)
Journal Article

This paper develops a simple signaling model of foreign currency borrowing that yields predictions about firm survival and performance during a currency crisis. Using a large panel of firm level data for South Korea we offer empirical support for man...

Systemic risk and the optimal seniority structure of banking liabilities (2018)

The paper argues that systemic risk must be taken into account when designing optimal bankruptcy procedures in general, and priority rules in particular. Allowing for endogenous formation of links in the interbank market we show that the optimal poli... Read More about Systemic risk and the optimal seniority structure of banking liabilities.

Systemic risk and macroeconomic fat tails (2017)

We propose a mechanism for shock amplification that potentially can account for fat tails in the distribution of the growth rate of national output. We argue that extreme macroeconomic events, such as the Great Depression and the Great Recession, wer... Read More about Systemic risk and macroeconomic fat tails.

Research in both economics and psychology suggests that, when agents predict the next value of a random series, they frequently exhibit two types of biases, which are called the gambler’s fallacy (GF) and the hot hand fallacy (HHF). The gambler’s fal... Read More about Do psychological fallacies influence trading in financial markets? Evidence from the foreign exchange market.

Entrepreneurial migration in an integrated world (2017)

Book Chapter

We develop a small, open economy, two-sector model with heterogeneous agents and endogenous participation in a labor matching market. There are two types of agents: workers and entrepreneurs. Both populations are heterogeneous. Workers are distinguis... Read More about Product and labor market entry costs, underemployment and international trade.

Journal Article
Bougheas, S. (2014). Pooling, tranching, and credit expansion. Oxford Economic Papers, 66(2), https://doi.org/10.1093/oep/gpt029

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...
