Excess zeros are encountered in many empirical count data applications. We provide a new explanation of extra zeros, related to the underlying stochastic process that generates events. The process has two rates, a lower rate until the first event, and a higher one thereafter. We derive the...

The demand for certain types of health care services depends on decisions of both the individual and the health care provider. This paper studies the conditions under which it is possible to separately identify the parameters driving the two decision processes using only count data on the total...

Rationale: Data from discrete choice experiments are usually analysed using probit or logit models or random effects extensions of these. These approaches produce estimates of the mean taste weights attributed to the attributes in the experiment by the sampled individuals. Further, if a cost...

The possibility of reoccurring waves of the novel coronavirus that triggered the 2020 pandemic makes it critical to identify underlying policy-relevant factors that could be leveraged to decrease future COVID-19 death rates. We examined variation in a number of underlying, policy-relevant,...

We develop and estimate a generalized labour supply model that incorporates work effort into the standard consumption-leisure trade-off. We allow workers a choice between two contracts: a piece rate contract, wherein he is paid per unit of service provided, and a mixed contract, wherein he...

Cross-country comparisons of subjective assessments may be ham- pered by sub-population speci…c response style. To correct for this, the use of vignettes has become increasingly popular - notably within cross- country health studies. However, the validity of vignettes as a means to re-scale...

We examine how personality relates to self-reported health satisfaction. With a nation-wide dataset from the United Kingdom, we provide evidence that personality influences how individuals report their satisfaction with their overall health. Using the classification of personality traits...

Este trabajo analiza los efectos que sobre la salud de los niños menores de cinco años tienen las características sanitarias de sus viviendas en Colombia. Específicamente, se consideran los impactos de estos factores sobre la mortalidad y la prevalencia de enfermedades diarreicas agudas...

This paper studies peer influences in adolescents' deviant behaviors, including drinking alcohol, doing dangerous things, skipping school and physical fighting, by a binary choice network model with heterogenous rational expectations proposed in Lee et al. (in press). For a wide range of...
