Recent studies debate how the unobserved dependence between the monetary return to college education and selection into college can be characterized. This paper examines this question using British data. We develop a semiparametric local instrumental variables estimator for identified features...

An overview is presented of some parametric and semi-parametric models, estimators, and specification tests that can be used to analyze ordered response variables.In particular, limited dependent variable models that generalize or-dered probit are compared to regression models that generalize...

We investigate the determinants of the support for cannabis legalizationfinding a causal effect of personal experience with cannabis use. Current and past cannabis users are more in favor of legalization. We relate this to self-interest and inside information about potential dangers of cannabis...

Preferences and attitudes to illicit drug policy held by individuals are likely to be an important in uence in the development of illicit drug policy. Amongst the key factors impacting on an individuals preferences over substance use policy are their beliefs about the costs and benefits of drug...

This paper investigates labour supply of the wives of the heads of households in Mexico City, with a focus on the impact of family structure. A static neoclassical structural model is used. We assume that each woman chooses her labour supply and corresponding income so that her utility is...

Abstract: In the Netherlands cannabis use is quasi-legalized. Small quantities of cannabis can be bought in cannabis-shops. We investigate how the distance to the nearest cannabis- shop affects the age of onset of cannabis use. We use a Mixed Proportional Hazard rate framework to take account of...

Attitudes towards risk play a major role in many economic decisions. In empirical studies one quite often assumes that attitudes towards risk do not vary across individuals. This papers questions this assumption and analyses which factors influence an individual's risk attitude. Based on...

This paper proposes a semiparametric estimator for single- and multiple index models.It provides an extension of the average derivative estimator to the multiple index model setting.The estimator uses the average of the outer product of derivatives and is shown to be root-N consistent and...

The inverse probability weighted Generalised Empirical Likelihood (IPW-GEL) estimator is proposed for the estimation of the parameters of a vector of possibly non-linear unconditional moment functions in the presence of conditionally independent sample selection or attrition.The estimator is...
