Should constraints on urban expansion be relaxed because of external agglomeration economies? In a system of heterogeneous cities, we demonstrate that second-best land use policy consists of a tax on city creation and a subsidy (tax) on urban development in cities in which the marginal-average...

The paper tests the role of agglomeration effects on the export decision of services firms. Recent theories on trade with heterogeneous firms predict that export participation goes along with sunk market-entry costs. Only the more productive firms will be able to overcome these sunk costs....

Matches between workers and jobs are better in thick labour markets than in thin ones. This CPB Discussion Paper measures match quality by the gap between worker skills and their job tasks in the Netherlands. The smaller the gap, the better the match between skills and tasks. The measured gaps...

Countries invest in international infrastructure in an effort to attract firms. Acquiring the position of a hub would make this effort successful. We use a model of international trade with monopolistic competition, increasing returns to scale and transport costs to analyse policy competition...

There are doubts about the effectiveness of regional policy. Well known are the fruitless attempts of Italy to bridge the gap between the Mezzogiorno and the North, of Germany to bridge the gap between the Neue Länder and the West, and of the European Commission to reduce regional disparities...

In this paper we measure the strength of agglomeration economies on the basis of Dutch regional data. The drift to the city has been going on for hundreds of years. As a result, most economic activity is concentrated in small geographical areas. The advantages of proximity of people and firms...

In this CPB Discussion Paper, we study how regulators may improve upon the efficiency of their energy technology adoption programs by exploiting readily observable information to limit rent extraction by firms. Using panel data on 862 investment decisions in the Netherlands, we find that rent...

With a novel approach this paper sheds light on the international tax planning possibilities of multinationals. The international corporate tax system is considered a network, just like for transportation, and ‘shortest’ paths are computed, minimizing tax payments for the...

We examine the impact of bilateral investment treaties (BITs) on bilateral FDI stocks using extensive data from 1985 until 2011. We correct for endogeneity using indicators for governance and membership of international organisations. We find that ratified BITs increase on average bilateral...

We examine the impact of bilateral and multilateral tax treaties on bilateral FDI stocks. First, we present panel regressions of the effects of treaties on FDI based on an extensive database of all OECD countries from 1985 onwards. We use geographic instruments to correct for the endogeneity of...
