This paper sets out to help explain why estimates of asset correlations based on equity prices tend to be considerably higher than estimates based on default rates. Resolving this empirical puzzle is highly important because, firstly, asset correlations are a key driver of credit risk and,...

This paper provides a theoretical and empirical appraisal of the shocks-institutions controversy as an explanation of unemployment heterogeneity in OECD countries. Since the influential work of Blanchard and Wolfers (2000), many studies have tried to explain the differences in the OECD...

In this paper, I present an empirical model of learning under ambiguity in the context of clinical trials. Patients are concern with learning the treatment effect of the experimental drug, but face the ambiguity of random group assignment. A two dimensional Bayesian model of learning is proposed...

Standard deterministic analysis of agricultural and biofuel policies can yield incomplete or misleading results. Stochastic analysis is especially important when policies have asymmetric effects and when there is intrinsic interest in uncommon events or the distribution of possible outcomes. The...
