The proposed Services Directive by the European Commission could increase intra European trade in commercial services by 30 to 60 percent. This paper analyses the welfare effects of the trade growth using an applied general equilibrium model WorldScan. Read also the accompanying <a href="http://www.cpb.nl/node/13360">press...

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...

We investigate four sources of uncertainty with CPB’s macroeconomic model SAFFIER: provisional data, exogenous variables, model parameters and residuals of behavioural equations. Uncertainty is an inherent attribute of any forecast. We apply a Monte Carlo simulation technique to...

This paper explains bilateral services trade using a gravity equation and compares the results with trade in goods. We analyse bilateral trade between the provinces of Canada and between the member states of the European Union. We conclude that the gravity equation explains the variability in...
