We investigate confidence intervals and inference for the instrumental variables model with weak instruments. Wald-based confidence intervals perform poorly in that the probability they reject the null is far greater than their nominal size. In the worst case, Wald-based confidence intervals...

The diffusion of health care technology is influenced by both the total market share of managed care organizations as well as the level of competition among them. This paper differentiates between HMO penetration and competition and examines their relationship to the adoption of cardiac...

We estabilsh the relationships between certain Bayesian and classical approaches to instrumental variables regression. We determine the form of priors that lead to posteriors for structural paameters that have similar properties as classical 2SLS and LIML and in doing so provide some new insight...

In this paper we consider the problem of making inference on a structural parameter in instrumental variables regression when the instruments are only weakly correlated with the endogenous explanatory variables. Adopting a local-to-zero assumption as in Staiger and Stock (1994) on the...

An exogenous impact function is defined as the derivative of a structural function with respect to an endogenous variable, other variables, including unobservable variables held fixed. Unobservable variables are fixed at specific quantiles of their marginal distributions. Exogenous impact...

We study the effect of fertility on labor supply in Argentina and Mexico exploiting a source of exogenous variability in family size first introduced by Angrist and Evans (1998) for the United States. Our results constitute the first external validation of the estimates obtained for the US....

This report was prepared for the Centre for Housing Research Aotearoa New Zealand (CHRANZ). The aim of this study is to identify a set of housing research projects addressing two related topics. First, the impact of economic, social and environmental changes on housing in New Zealand's...

Despite the pervasive nature of land use planning and land use regulation, evaluation of the costs and benefits of these policies has received only limited attention. This paper presents an empirical methodology, based on clear microeconomic foundations, for the evaluation of benefits and costs...
