This paper considers a general heteroskedastic error component model using panel data, and derives a joint LM test for homoskedasticity against the alternative of heteroskedasticity in both error components. It contrasts this joint LM test with marginal LM tests that ignore the...

Data with which to study disability dynamics usually take the form of successive current-status measures of disability rather than a record of events or spell durations. One recent paper presented a semi-Markov model of disability dynamics in which spell durations were inferred from sequences of...

Cohabitation is an alternative to marriage and to living independently for an increasing number of Americans.

This paper focuses on the movement of data-based social policy analysis from a single country cross-sectional frame to a multi-country panel frame. It provides examples of policy insights this movement to panel data has permitted, both with respect to economic well-being and behavior-using data...

This paper provides a guide to statistically based methods for estimating the extra costs of educating disadvantaged students, shows how these methods are related, and compares state aid programs that account for these costs in different ways. We show how pupil weights, which are included in...

This paper develops a new approach to testing hypotheses about the causes of discrimination in housing sales. We follow previous research by using data from fair housing audits, a matched-pair technique for comparing the treatment of equally qualified black and white home buyers. Our...
