This paper employs fixed and random effects regressions to analyze panel data from the 50 states and Washington, D.C., between the years of 1980 and 2005, to estimate the relationship between the death penalty and homicide rate, and the degree to which this relationship affects crime outcomes....

"Nonprofit theory predicts nonprofit enterprises will be more trustworthy than for-profit enterprises in the delivery of goods for which quality is difficult to determine because nonprofit enterprises are legally required to reinvest all profits back into the enterprise. Theoretically, consumers...

Modelling and inference with higher-dimensional variables, including studies in multivariate time series analysis, raise challenges to our ability to ``scale-up'' statistical approaches that involve both modelling and computational issues. Modelling issues relate to the interest in parsimony of...

Bayesian nonparametric methods are useful for modeling data without having to define the complexity of the entire model a priori, but rather allowing for this complexity to be determined by the data. Two problems considered in this dissertation are the number of components in a mixture model,...

This thesis examines causal inference related topics involving intermediate variables, and uses Bayesian methodologies to advance analysis capabilities in these areas. First, joint modeling of outcome variables with intermediate variables is considered in the context of birthweight and censored...

Dynamic models, also termed state space models, comprise an extremely rich model class for time series analysis. This dissertation focuses on building state space models for a variety of contexts and computationally efficient methods for Bayesian inference for simultaneous estimation of latent...
