In the 1980s and 1990s successive United Kingdom governments enacted a series of reforms to establish a more market-oriented economy, closer to the American model and further away from its Western European competitors. Today, the United Kingdom is one of the least regulated economies in the...

The central concern of this paper is parameter heterogeneity in models specified by a number of unconditional or conditional moment conditions and thereby the provision of a framework for the development of apposite optimal m-tests against its potential presence. We initially consider the...

This study examined the career paths of 415 Title IV-E MSW graduates in one state retrospectively over 180months post-graduation to discover factors that could be important in affecting retention in public child welfare agencies. The Title IV-E educational program is designed to be a retention...

This article reviews a number of recent contributions to estimation and inference for models defined by moment condition restrictions. The particular emphasis is on the generalized empirical likelihood class of estimators as an alternative to the generalized method of moments. Estimation methods...

In an effort to improve the small sample properties of generalized method of moments (GMM) estimators, a number of alternative estimators have been suggested. These include empirical likelihood (EL), continuous updating, and exponential tilting estimators. We show that these estimators share a...
