This paper draws on literatures on vouchers and discrimination, and derives an optimal voucher scheme as a supplement to standard anti-discrimination policies, including affirmative action. Surveying current policy methods, it compares efficiency and distributional effects of vouchers to those...

Given demographic trends, public policies in the future may be aimed at stimulating the availability of nursing home care in the U.S. This paper estimates how certificate of need laws, Medicaid reimbursement rates, and state corporate income tax rates affect the availability of nursing home care...

Using samples from the National Longitudinal Survey of Youth (1979), a longitudinal data set from the United States, this study demonstrates that the worker's positive attitude affects his/her wage not only directly, but also indirectly through its effects on happiness. Assuming endogeneity of...

To examine whether or not the worker's attitude to life affects his/her earnings, this study estimates wage equations with positive attitude as an explanatory variable under different econometric specifications. The results obtained from both cross-sectional and panel data confirm that positive...

We examine a simple estimator for the multivariate moving average model based on vector autoregressive approximation. In finite samples the estimator has a bias which is low where roots of the characteristic equation are well away from the unit circle, and more substantial where one or more...

This paper provides a critical survey of the methods employed to model the effects of risk in econometric models. Most of the popular methods are shown to suffer from errors-in-variables bias, and an instrumental variable method is suggested to overcome this problem. The technique exploits the...
