Corruption and inequality of wealth amongst the very rich.

Corruption may lead to tax evasion and unbalanced favors and this may lead to extraordinary wealth amongst a few. We study for 13 countries 6 years of Forbes rankings data and we examine whether corruption leads to more inequality amongst the wealthiest. When we correct in our panel model for current and one-year lagged competitiveness and GDP growth rates, we find no such effect.

Estimating Independent Locally Shifted Random Utility Models for Ranking Data.

We consider the estimation of probabilistic ranking models in the context of conjoint experiments. By using approximate rather than exact ranking probabilities, we avoided the computation of high-dimensional integrals. We extended the approximation technique proposed by Henery (1981) in the context of the Thurstone-Mosteller-Daniels model to any independent locally shifted random utility model.

Weather conditions and daily television use in the Netherlands, 1996-2005.

This study examines the impact of daily atmospheric weather conditions on daily television use in the Netherlands for the period 1996-2005. The effects of the weather parameters are considered in the context of mood and mood management theory. It is proposed that inclement and uncomfortable weather conditions are associated with lower human mood, and that watching entertainment and avoiding informational programs may serve to repair such mood.

Modeling healthcare expenditures: overview of the literature and evidence from a panel time-series model.

The rapid growth of healthcare expenditures in the past 40 years in many industrial countries has contributed to an improvement in life expectancy and the quality of life, but has also jeopardized the sustainability of public budgets. For the future, it is important to get more insight into the determinants of this growth. Factors, such as aging, income growth and technological development have been discussed extensively.
