We present a simulation model designed to determine the impact on congestion of policies for dealing with non-recurrent congestion (i.e. travel time uncertainty).

This study offers a simultaneous equations model of the birth process with seven endogenous variables: four birht inputs, and three birth outputs. Our analysis conditions on twenty-four exogenous variables. The data are taken the NLSY. Separate analyses are performed on five different groups:...

In an important and influential paper, Card and Krueger argued that proxies for school quality positively affect the rate of return to future education. In this paper, we analyze a variant of the Card and Krueger model using a hierarchical Bayesian approach and school-level quality data from the...

This paper develops new Bayesian methods for semiparametric inference in the partial linear Normal regression model. These methodes draw solely on teh Normal linear regression model with natural conjugate prior. Hence, analytical finite sample results are available which do not suffer form...

We survey modern models of delegation which assume that a boss and subordinate pursue their own goals. Among the major themes covered are thefolling: the conditions under which the boss will prefer to delegate versus those in which she will prefer to retain authority; the ways in which a boss...
