This dissertation consists of three essays that focus on a Bayesian estimation of stochasticcost frontiers for electric generation plants. This research gives insight into the changingdevelopment of the electric generation market and could serve to inform both private investmentand public policy...

Bayesian estimation has gained ground after Markov Chain Monte Carlo process made it possible to sample from exact posterior distributions. This research aims at contributing to the ongoing debate about the relative virtues of the Frequentist and Bayesian theories by concentrating on the...

In this work, we begin with an investigation into the temporal correlation in default risk. We first establish a link between the dynamics of house price changes and the dynamics of default rates in the Gaussian copula framework by specifying a time series model for a common risk factor. We show...
