This paper analyses the causal effect of education on the probability of being overweight by using longitudinal data of Australian identical twins. The data include self-reported and clinical measures of body size. The prevalence of overweight and obesity is growing rapidly in many countries....

During the last twenty years the share of researchers in the workforce has been rising in OECD countries. In the same period, the distribution of schooling has become more equal. This paper proposes that the rise in the proportion of researchers is caused by the decline in schooling...

International negotiations on the liberalisation of service trade are concentrated at non-tariff barriers (NTBs). National government measures form important obstacles for service providers when they want to access foreign markets. International studies predict substantial welfare benefits...

After the flood disaster in 1953 in the southwestern part of the Netherlands, Van Dantzig tried to solve the economic-decision problem concerning the optimal height of dikes. His formula with a fixed exceedance probability after each investment (Econometrica, 1956) is still in use today in...

This paper empirically explores the relationship between competition design and productive efficiency in the railway industry. We use Data Envelopment Analysis (DEA) to construct efficiency scores, and explain these scores, using variables reflecting institutional factors and competition...

On the basis of two datasets, the German Socio-Economic Panel 2002 and the Dutch Social Position and Use of Provision Survey 2002, we investigate the importance of characteristics related to immigration for the labour market position of Turkish immigrants. We use regression techniques to...

Reducing the emission of greenhouse gases to reduce climate change is high on the policy agenda. Discounted costs of reduction are estimated to be substantial. They depend on the employment of various flexibility mechanisms that affect these costs. One of these flexibility mechanisms is the...

Increases in inequality between low and high-skilled workers are likely to affect welfare state policies in upcoming decades. Demand for redistribution puts pressure on marginal income-tax rates and other social security measures. We come to this conclusion by confronting expected supply and...

We review the empirical literature about the implications of the computerization of the labor market to see whether it can explain observed computer adoption patterns and (long-term) changes in the wage structure. Evidence from empirical micro studies turns out to be inconsistent with macro...

In Europe, declining corporate tax rates have come along with rising tax-to-GDP ratios. This paper explores to what extent income shifting from the personal to the corporate tax base can explain these diverging developments. We exploit a panel of European data on legal form of business to...
