A variety of qualitative dependent variable models are surveyed with attention focused on the computational aspects of their analysis. The models covered include single equation dichotomous models; single equation polychotomous models with unordered, ordered, and sequential variables; and...

A preliminary investigation of two specification error problems in truncated dependent variable models is reported. It is shown that heteroscedasticity in a tobit model results in biased estimates when the model is misspecified. This differs from the OLS model where estimates are still...

[eng] Estimation of Short Run and Long Run Elasticities of Energy Demand from Panel Data Using Shrinkage . Estimators by Hongyi Li, G.S. Maddala and Robert P. Trost . In the analysis of panel data, there are, broadly speaking, three approaches: to present separate estimates of the parameters in...

This paper contains further analysis of the questions discussed in two papers by Joskow concerning what rate of return a regulated firm will request and what rate of return it will be granted in a formal regulatory process. Using Florida data, this paper extends Joskow's approach by examining...

This article examines and quantifies the relationship between local amenities and prices in an equilibrium model, demonstrating the role of non-traded goods and federal taxes. I derive formulae using factor shares to infer local land rents, productivity, and the total value of amenities from...

We estimate peer effects for fourth graders in six European countries. The identification relies on variation across classes within schools. We argue that classes within primary schools are formed roughly randomly with respect to family background. Similar to previous studies, we find sizeable...
