This paper addresses the timing of a location's historical transition from rural to urban activity. We test whether urbanization occurs sooner in places with higher agricultural potential and comparatively lower transport costs, using worldwide data that divide the earth's surface at half-degree...

Large scale tracking policies, allowing academically apt pupils to enter a select group of secondary schools, can be found in many Sub-Saharan countries. However, evidence on the impact of these policies on school outcomes, especially school participation, is limited. This paper fills this gap...

This paper presents evidence about the impact on school enrollment of a program in Ecuador that gives cash transfers to the 40 percent poorest families. The evaluation design consists of a randomized experiment for families around the first quintile of the poverty index and of a regression...

The direct impact of local public goods on welfare is relatively easy to measure from land rents. However, the indirect effects on home and job location, on land use, and on agglomeration benefits are hard to pin down. We develop a spatial general equilibrium model for the valuation of these...

The effects of a policy measure often reach the consumer only after one or more intermediatesteps, for instance because the measure lowers the cost of an input for an industry producinga consumer good. This paper is concerned with the question how to measure such indirect effectscorrectly under...

Urban re-development projects may generate various positive as well as negative spatial externalities to the existing population in a given area. This study aims to assess the order of magnitude of the expected net benefits for incumbent residents from a large scale project in the Southern part...

This paper addresses the question to what extent the performance of industrial sites is affected by their local economic structure and accessibility. For this aim, we test for the existence of statistically significant relationships between agglomeration externalities (specialization, diversity,...
