We provide new cross-country evidence on smoking persistence in Europe, which can be due to both true state dependence and individual unobserved heterogeneity. We distinguish between the two by using semi-parametric panel data selection methods, applied to both the smoking participation and the...

We provide new cross-country evidence on smoking persistence in Europe, which can be due to both true state dependence and individual unobserved heterogeneity. We distinguish between the two by using semi-parametric nonlinear panel data methods, applied to both the smoking participation and the...

This paper analyzes tobacco demand within a discrete choice framework. Using binomial and multinomial logit models with random effects, and an unbalanced panel data set of Norwegian households over a twenty year period, we first consider the decisions a) whether to smoke or not, and b) given the...

This paper develops an extension of the class of finite mixture models for longitudinal count data to the bivariate case by using a trivariate reduction technique and a hidden Markov chain approach. The model allows for disentangling unobservable time-varying heterogeneity from the dynamic...

The gateway hypothesis proposes that cannabis use increases the risk of starting to consume hard drugs. We test this controversial, but influential, hypothesis on a sample of cannabis users employing a unique set of drug prices. A flexible approach is developed to identify the causal gateway...

This dissertation consists of empirical essays within the subject of health economics. There are four essays in applied micro-econometrics and, as data in Essays 2 and 4 have a panel format, econometric methods for panel data are applied. Tobit-type models for limited dependent variables are...

This study exploits a natural experiment in Belgium to estimate the effect of co-payment increases on the demand for physician services. It shows how a differences-in-differences estimator of the price effects can be decomposed into effects induced by the common average proportional price...

This paper studies the effect of fruit and vegetable consumption on human well-being. Using individual-level panel data from a representative sample of Australian households, I estimate the intake of fruit and vegetables to have positive and statistically significant impacts on a wide range of...
