The physical or absolute geography of Sub-Saharan Africa (SSA) is often blamed for its poor economic performance. A country's location however not only determines its absolute geography, it also pins down its relative position on the globe vis-a-vis other countries. This paper assesses the...

In explaining the uneven spatial distribution of economic activity, urban economics and new economic geography (NEG) dominate recent research in economics. A main difference between these two approaches is that NEG stresses the role of spatial linkages whereas urban economics does not do so. We...

We develop a spatial model of energy exploitation where energy sources are differentiated by their geographic location and energy density. The spatial setting creates a scaling law that magnifies the importance of differences across energy sources. As a result, renewable sources twice as dense,...

We extent a solvable version of the core-periphery agglomeration model to four countries located in two regions. The paper shows that there might still be a race to the bottom in capital income tax rates despite agglomeration rents earned by the mobile factor. We find that intra-regional tax...

This paper analyzes the impact of fiscal competition through infrastructure in a New Economic Geography framework. It is shown that regional competition leads to convergence if the trade costs are high but induces divergence if trade cost have fallen below a certain value. Moreover, fiscal...

The 2008 Nobel prize for economics was awarded to Paul Krugman for three papers - Krugman (1979, 1980, 1991). In this paper we illustrate that, indeed, these three papers are closely connected. We present - a summary of - the papers using a unified framework. Central in the discussion is the...

The paper combines an economic-geography model of agglomeration and periphery with a model of species diversity and looks at optimal policies of biodiversity conservation. The subject of the paper is natural biodiversity, which is inevitably impaired by anthropogenic impact. Thus, the economic...

We review and interpret the main theoretical developments in the gravity literature from its very early, a-theoretical applications to the latest structural contributions. We also discuss challenges and implement methods to estimate empirical gravity equations. We finish with a presentation and...

We examine the evolution of market potential and its role in driving economic growth over the long twentieth century. Theoretically, we exploit a structural gravity model to derive a closed-form solution for a widely-used measure of market potential. We are thus able to express market potential...

Using a natural experiment from Germany, we show that temporary place-based subsidies generate persistent effects on economic density. We identify employment and capital formation as main channels for higher income per square kilometer. As the spatial regression discontinuity design allows us to...
