We estimate the fraction of hidden unemployment in the disability insurance (DI) inflow rate on the basis of a longitudinal administrative data set of Dutch employers for the period 1994-2003. This fraction can be identified by imposing so-called exclusion restrictions on variables that are...

In this article, we estimate the degree of substitution between enrolment into Disability Insurance (DI) and Unemployment Insurance (UI) in the Netherlands. Starting in the 1990s many policy measures aimed at reducing DI enrolment, and increase labour force participation. We quantify whether...

In this paper we study the risk perception of traffic participants. Firstly, we give an overview of previously used methodologies for the monetary valuation of transport safety. These methodologies do not distinguish between the individual's assessment of probabilities and her valuation of...

In this paper we analyze the impact of a simple regional economic policy in the context of the core periphery model of the New Economic Geography. More specifically, we look at the welfare effects of a decrease in transport cost that is financed by a lump-sum tax on all inhabitants of the...

During the 1980s and 1990s, the Netherlands experienced a strong increase in the labour force participation of women. This study investigates the increase of participation over the successive generations of women, and produces an educated guess for future participation. For this purpose, we...

This paper investigates the effects of education vouchers for teachers. We study effects on enrollment and completion of higher education programs, and on the retention of teachers in the education sector. We do this by exploiting a fuzzy regression discontinuity design. Read also the...

Distributed Denial of Service (DDoS) attacks are a frequently occurring type of cybercrime, with potentially large costs to the real economy. We propose a simple model of the size and direction of DDoS attacks. The main predictions of the model are that effective botnets are located in...

A consequence of melting Arctic ice caps is the commercial viability of the Northern Sea Route, connecting North-East Asia with North-Western Europe. This will represent a sizeable reduction in shipping distances and a decrease in the average transportation days by around one-third compared to...

The authors investigate the effectiveness and efficiency of alternative measures to increase standards in low-income countries. They do this in a two-country framework where (a) trade and standards in low-income countries are negatively related, and (b) free trade is no longer optimal for the...
