I study optimal financial contracting when neither cash flows nor the risk profile of project choices are verifiable. Using a contracting framework, I show the resulting two frictions (cash-diversion and asset-substitution) are intricately linked: to address the cash-diversion problem, an...

We theoretically investigate the effect of public information — such as credit ratings and securities analysts' reports — on investor welfare in the context of delegated asset management. Specifically, we ask: does more precise public information increase investor welfare by decreasing an...

We analyze the role of risk limits in the provision of incentives to acquire valuable information for efficient risk management. We study the optimal contract of a trader who (a) must privately exert costly effort in order to collect information and (b) may have access to a costly second opinion...

We develop a macroeconomic portfolio stress test that is specifically geared towards small and medium-sized banks. We combine a credit risk stress test which simulates credit impairments via a CreditMetrics type multi-factor portfolio model with an income stress test in the form of dynamic panel...

In this paper, we analyze the conflicts of interest of an informed agent who is responsible for divulging his private information about a company and has a reward function positively dependent on its stock price. We assume that the demand for the stock is subject to shocks that may increase...

This paper presents a model in which cash holding imposes a negative externality because it worsens future adverse selection in markets for long-term assets, which impairs their role for liquidity provision. Adverse selection worsens when potential sellers of long-term assets hold more cash...

In recent years new methods and models have been developed to quantify credit risk on a portfolio basis. CreditMetrics (tm), CreditRisk+, CreditPortfolio (tm) are among the best known and many others are similar to them. At first glance they are quite different in their approaches and...

Our paper addresses firm size as a driver of systematic credit risk in loans to small and medium enterprises (SMEs). Key contributions are the use of a unique data set of SME lending by over 400 German banks and relating systematic risk to the size dependence of regulatory capital requirements....
