Instruments for credit risk transfer arise endogenously from and interact with optimizing behavior of their users. This is particularly true with credit derivatives which are usually OTC contracts between banks as buyers and sellers of credit risk. Recent literature, however, does not account...

This paper models the strategic interaction between a rating agency, a banking sector and a bank regulator who lacks information about bank asset risk. The regulator can either (1) make bank capital requirements contingent on credit ratings; or (2) set rating independent capital requirements....

How does asset encumbrance affect the fragility of intermediaries subject to rollover risk? We offer a model in which a bank issues covered bonds backed by a pool of assets that is bankruptcy remote and replenished following losses. Encumbering assets allows a bank to raise cheap secured debt...

Within a framework of debt renegotiation and a priori private information, what is the role of outside and inside collateral? The literature shows that unobservability of the project’s returns implies that the high-risk borrower is more inclined to pledge outside collateral than is the...

The introduction of the euro marks a milestone in the process of European financial market integration. This paper analyzes the implications of the euro for cross-border banking activities. A portfolio model is used which captures the role of banks as providers of informational and of...

Many observers argue that one of the major causes of the 2007-2009 financial turmoil was the abnormal accumulation of risk by banks. This paper provides a signaling explanation for this "risk race." If banks' returns can be observed while risk cannot, less efficient banks can hide their type by...

This paper studies how a bank's diversification affects its own risk taking behavior and the risk taking of competing, nondiversified banks. In particular, I test whether greater geographic diversification of banks has effects on the risk taking behavior of nondiversified competitors beyond...

Using banks' internal models for regulatory purposes, while aimed at making capital requirements more accurate, invites regulatory arbitrage. I show how the strategic use of risk models can be avoided by penalizing banks with low risk-weights when they suffer abnormal losses. As defaulting banks...

The recent financial crisis has forced a rethink of banking regulation and supervision and the role of financial innovation. This paper develops a model where prudent banks may signal their type through high capital ratios. Capital regulation may ensure separation in equilibrium, but deposit...
