We study the effects of competition in a context in which people's actions can not be contractually fixed. We find that in such an environment the very presence of competition does neither increase efficiency nor does it yield any payoff gains for the short side of the market. We also find that...

There is a concern that ordered responses on health questions may differ acrosspopulations or even across subgroups of a population. This reporting heterogeneity mayinvalidate group comparisons and measures of health inequality. This paper proposes a test fordifferential reporting in ordered...

This discussion paper resulted in a publication in 'Social Science & Medicine' (2010). Volume 70, issue 3, pages 428-438.<P> A strong relationship between health and socioeconomic status is firmly established. Yet, partly due to the multidimensional and dynamic nature of the variables, the causal...</p>

I apply Ricardo’s principle of comparative advantage to a theory of factor substitutability in a model with a continuum of worker and job types. Highly skilled workers have a comparative advantage in complex jobs. The model satisfies the distance‐dependent elasticity of substitution (DIDES)...

Heterogeneity in reporting of health by socio-economic and demographic characteristics potentially biases the measurement of health disparities. We use anchoring vignettes to identify socio-demographic differences in the reporting of health in Indonesia, India and China. Homogeneous reporting by...

This discussion paper led to an article in the <I>Journal of Human Resources</I> (2011). Volume 46(4), pages 695-721.<P> While there is no doubt that health is strongly correlated with education, whether schooling exerts a causal impact on health is not yet firmly established. We exploit Dutch compulsory...</p></i>

Measurement of inequity in health care delivery has focused on the extent to which health care utilisation is or is not distributed according to need, irrespective of income. Studies using cross-sectional data have proposed various ways of measuring and standardizing for need, but inevitably...

Europe aims at combining income growth with improvements in social cohesion as measured by income and health inequalities. We show that, theoretically, both aims can be reconciled only under very specific conditions concerning the type of growth and the income responsiveness of health. We...

Nowadays many countries and governments must confront one of the most challenging food and health disasters ever to face human-kind: an epidemic of obesity. Even though several factors can lead to obesity, mostly food industry has been blamed for making people fat. Hence, this article provides a...
