On the basis of a large (new) dataset of cities in Europe, North Africa and the Middle East in the millennium between 800 and 1800, we try to provide an answer to the question why, during this millennium, the urban center of gravity moved from Iraq (or more generally the Arab world) to Western...

Abstract This paper sheds empirical light on the relationship between agglomeration and economic growth and its impact on the convergence hypothesis. Using a sample of 208 European regions over 25 years, ‘standard’ growth regressions are estimated using panel data techniques. Both the effect...

The Netherlands is one of the most flood prone countries in the world. It also has the best flood defenses in the world that are built to make floods an extremely rare event. This paper uses the unique Dutch setting to provide evidence on the price and perception of rare environmental disasters....

Sub-Saharan Africa's (SSA) physical geography is often blamed for its poor economic performance. A country's geographical location does, however, not only determine its agricultural conditions or disease environment. It also pins down a country's relative position vis-a-vis other countries,...
