This paper presents a model of a bank subject to liquidity shocks that require borrowing from a lender of last resort. Two government agencies with different objectives may perform this function: a central bank and a deposit insurance corporation. Both agencies supervise the bank, i.e. collect...

In this paper, I first provide a unifying approach to Mean-Variance analysis and Value at Risk, which highlights their similarities and differences. Then I use it to explain how fund managers can take investment decisions within the well-known Mean-Variance allocation framework that satisfy the...

We conduct an extensive empirical analysis of VIX derivative valuation models over the 2004-2007 bull market and the subsequent financial crisis. We show that existing models yield large distortions during the crisis because of their restrictive volatility mean reverting assumptions. We propose...

We derive computationally simple score tests of serial correlation in the levels and squares of common and idiosyncratic factors in static factor models. The implicit orthogonality conditions resemble the orthogonality conditions resemble the orthogonality conditions of models with observed...

This paper derives closed-form solutions for values of debt and equity in a continuoustime structural model in which the demands of creditors to be repaid cause a firm to be put into bankruptcy. This allows discussing the effect of creditor coordination in recovering money on the values of debt,...

We characterize full implementation of social choice sets in mixed strategy Bayesian equilibrium. Our results concern both exact and virtual mixed implementation. For exact implementation, we identify a strengthening of Bayesian monotonicity, which we refer to as mixed Bayesian monotonicity. It...

In this paper we study the determinants of banks’ decision to adopt a transactional website for their customers. Using a panel of commercial banks in the United States for the period 2003-2006, we show that although bank-specific characteristics are important determinants of banks’ adoption...
