This paper offers the first instrumental variables estimates of the wage returns to volunteer experience. The returns are substantial and differ considerably by gender. The results imply that the unequal valuation of volunteer experience by gender is more important in explaining the gender...

The present paper proposes a strategy for estimating panel data models in the presence of sample selection and endogeneity arising from endogenous explanatory variables and unobserved heterogeneity. We propose three alternative tests for selection bias and estimation strategies to correct for...

Self-reported home values are widely used as a measure of housing wealth by researchers employing a variety of data sets and studying a number of different individual and household level decisions. The accuracy of this measure is an open empirical question, and requires some type of market...

The economic returns to education in transition countries have been extensively evaluated in the literature. The present study contributes to this literature by estimating the returns to education in Georgia during the last transition period 2000-04. We find very low returns to education in...

An increasing number of longitudinal data sets collect expectations information regarding a variety of future individual level events and decisions, providing researchers with the opportunity to explore expectations over micro variables in detail. We present a theoretical framework and an...

We consider estimation of panel data models with sample selection when the equation of interest contains endogenous explanatory variables as well as unobserved heterogeneity. We offer a detailed analysis of the pooled two-stage least squares (pooled 2SLS) and fixed effects-2SLS (FE-2SLS)...

We propose an Instrumental Variable method for Generalised Accelerated Failure Time (GAFT) models that adjust for possible endogeneity of the intervention of interest, without suffering the problems of the intention-to-treat method. We develop an estimatiom procedure that collapses to the linear...

This paper asks which aspects of a structural Nonparametric Instrumental Variables Regression (NPIVR) can be identified well and which ones cannot. It contributes to answering this question by characterizing the identified set of linear continuous functionals of the NPIVR under norm constraints....

This paper evaluates how a light-touch parenting program for parents of children below school entry age affects maternal well-being. We first analyze data from a randomized controlled trial focusing on more advantaged parents. Second, we use a sample of mothers from deprived neighborhoods, for...

This paper examines the identifying power of instrument exogeneity in the treatment effect model. We derive the identification region of the potential outcome distributions, which are the collection of distributions that are compatible with data and with the restrictions of the model. We...
