We incorporate risk aversion into the technology component of the production function. In a traditional theoretic framework, we show that an increase in risk aversion increases unemployment and reduces potential output. Our out-of-sample forecasting experiments suggest that while interest rates...

This paper proposes finite mixtures of different Archimedean copula families as a flexible tool for modelling the dependence structure in multivariate data. A novel approach to estimating the parameters in this mixture model is presented by maximizing the penalized marginal likelihood via...

A crucial problem in Bayesian posterior computation is efficient sampling from a univariate distribution, e.g. a full conditional distribution in applications of the Gibbs sampler. This full conditional distribution is usually non-conjugate, algebraically complex and computationally expensive...

In this paper we show that fully likelihood-based estimation and comparison of multivariate stochastic volatility (SV) models can be easily performed via a freely available Bayesian software called WinBUGS. Moreover, we introduce to the literature several new specifications that are natural...

The nonparametric part of a semiparametric regression model usually involves prior specification for an infinite-dimensional parameter F. This paper introduces a class of finite mixture models based on B-spline distributions as an approximation to priors on the set of cumulative distribution...
