The results of this study for the 50 states imply that considerations of distance play an important role in the migration decision of blacks, with the distance variable being statistically significant at the five percent level or better in 80 percent of the cases. The racial composition variable...

Our article considers the class of recently developed stochastic models that combine claims payments and incurred losses information into a coherent reserving methodology. In particular, we develop a family of Heirarchical Bayesian Paid-Incurred-Claims models, combining the claims reserving...

We propose an approach to the regularization of covariance matrices that can be applied to any model for which the likelihood is available in closed form. The approach is based on using mixtures of double exponential or normal distributions as priors for correlation parameters, and on maximizing...

Harrison and Kreps showed in 1978 how the heterogeneity of investor beliefs can drive speculation, leading the price of an asset to exceed its intrinsic value. By focusing on an extremely simple market model—a finite-state Markov chain—the analysis of Harrison and Kreps achieved great...

It is well known that a unit tax on the emissions of polluting firms and an equal unit subsidy for emissions abated are not symmetrical instruments. However, when no entry-exit conditions are at stake, as in the case of polluting households, the tax and subsidy are equivalent. Moreover, any...

When all countries tax domestic emissions of a pure global pollutant at a rate equal to global marginal damage, some of these countries - typically, developing countries - are likely to be worse off. To win the cooperation of such developing countries, it is often advocated that they receive...

We propose a general class of models and a unified Bayesian inference methodology for flexibly estimating the density of a response variable conditional on a possibly high-dimensional set of covariates. Our model is a finite mixture of component models with covariate-dependent mixing weights....
