Following the seminal contribution of Kiyotaki and Moore (1997), the role of collateral constraints for business cycle fluctuations has been highlighted by several authors and collateralized debt is becoming a popular feature of business cycle models. In contrast, Kocherlakota (2000) and Cordoba...

We propose a framework that allows a portfolio manager to quantify the probability of simultaneous losses in multiple assets of a collateral portfolio. Using this framework, we propose a methodology to conduct stress tests on the market value of the portfolio of collateral when undesirable...

We provide a model with endogenous portfolios of secured and unsecured household debt. Secured debt is collateralized by durables whereas unsecured debt can be discharged in bankruptcy procedures. We show that the model matches the main quantitative characteristics of observed wealth and debt...

Limited access of entrepreneurs to credit constrains the creation and growth of private firms. In Africa, access to credit is particularly limited for small and medium enterprises (SMEs) due to unclear property rights and the lack of assets that can be used as collateral. This paper presents a...

We examine the effects of collateralized borrowing in a realistically parameterized life-cycle portfolio choice problem. We provide basic intuition in a two-period model and then solve a multi-period model computationally. Our analysis provides insights into life-cycle portfolio choice relevant...

The Large Value Transfer System (LVTS) loss-sharing mechanism was designed to ensure that, in the event of a one-participant default, the collateral pledged by direct members of the system would be sufficient to cover the largest possible net debit position of a defaulting participant. However,...

Understanding the nature of credit risk has important implications for financial stability. Since authorities notably, central banks focus on risks that have systemic implications, it is crucial to develop ways to measure these risks. The difficulty lies in finding reliable measures of aggregate...
