We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value-added output, we calculate for each state the efficient frontier for investments in the real economy. We study how rapidly...

This paper examines the impact of a public credit registry on the repayment behavior of borrowers. We implement an experimental credit market in which loan repayment is not third-party enforceable. We compare market outcome with a credit registry to that without a credit registry. This...

We analyze optimal risk management strategies for a regulatory restricted bank financed with deposits and equity in an infinite horizonmodel. The bank has a positive franchise value from rents coming from deposit related services (liquidity provision, payment services, safety storage), and from...

In this paper, we investigate how investors who face both equity risk andcredit risk would optimally allocate their financial wealth in a dynamic continuous-time setup. We model credit risk through the defaultable zero-coupon bond and solve the dynamics of its price after pricing it. Using...

This paper investigates the impact of heterogeneous beliefs of professional investors on the currency options market. Using a unique data set with detailed information on the foreign-exchange forecasts of about 50 market participants over more than ten years, we construct an empirical proxy for...

This paper derives an analytic expression for the distribution of the average volatility in the stochastic volatility model of Hull and White. This result answers a longstanding question, posed by Hull and White (Journal of Finance 42, 1987), whether such an analytic form exists. Our findings...

This paper derives fundemental arbitrage pricing results in finite dimensions in a simple unified framework using Tucker's theorem of the alternative. Frictionless results plus those with dividends, periodic interest payments, transaction costs, different interest rates for lending and...

Due to their underlying assumptions, the standard concepts of risk aversion and preference for the present are generally defined separately and represented by scalar measures, and this implies many shortcomings. More specifically, if measured by a scalar, the risk aversion remains unchanged,...

In this paper we solve an intertemporal portfolio problem with correlation risk, using a new approach for the simultaneous modeling of stochastic correlation and volatility. The solutions of the model are in closed form and include an optimal portfolio demand for hedging correlation risk. We...

We study arbitrage opportunities in diverse markets as introduced by R. Fernholz in [2]. By a change of measure technique we are able to generate a variety of diverse markets. The construction is based on an absolutely continuous but non-equivalent measure change which implies the existence of...
