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...

We develop methods for testing the hypothesis that an econometric model is undeerindentified and inferring the nature of the failed identification. By adopting a generalized-method-of moments perspective, we feature directly the structural relations and we allow for nonlinearity in the...

We compare the effects of selective and non selective secondary education on children’s test scores, using British data from the National Child Development Study (NCDS). Test scores are modelled as the output of an additive production function. Inputs include family and school characteristics,...

We analyze the cyclical effects of moving from risk-insensitive (Basel I) to risk-sensitive (Basel II) capital requirements in the context of a dynamic equilibrium model of relationship lending in which banks are unable to access the equity markets every period. Banks anticipate that shocks to...

The quote in the title refers to a recurring principle in the Antitrust Guidelines for the Licensing of Intellectual Property, issued jointly by the US Department of Justice and the Federal Trade Commission in 1995. That report states that “The Agencies” general approach in analyzing a...

We study the dynamic stability of fidelity networks, which are networks that form in a mating economy of agents of two types (say men and women), where each agent desires direct links with opposite type agents, while engaging in multiple partnerships is considered an act of infidelity....
