Early research has documented that the large scale equity market liberalizations of the last decade led the subsequent rise in aggregate equity indices, investment booms, capital flows and economic growth. An important and unaddressed issue is the normative question of whether and how these...

We present estimators for semiparametric regression models where the dependent variable is grouped, that is, known to fall in a specified group with observable thresholds while its true value remains latent. Income, weeks unemployed, and treatment length are examples of such variables. Because...

The induced demand model postulates that physicians respond to adverse income shocks by electing to perform more remunerative procedures. Recent work verifies the predictions of this model, finding a strong shift away from natural deliveries to the more highly reimbursed cesarean delivery in...

Sample selection models provide an important way of accounting for economic decisions that combine discrete and continuous choices and of correcting for nonrandom sampling. Nonparametric estimators for these models are developed in this paper. These can be used for estimating shapes and...

This paper derives the asymptotic distribution theory for censored regression models with endogenous covariates under no parametric assumptions on the disturbance distribution, extending the modeling framework of Powell (1986). While it is well known that under some restrictions the use of...

This paper develops minimum distance estimators for nonparametric models where the dependent variable is known only to fall in a specified group with observable thresholds, while its true value remains unobserved and possibly censored. Such data arise commonly in major U.S and U.K data sets...
