The notion of the 'Silk Road' that the German geographer Ferdinand von Richthofen invented in the 19th century has lost attraction to scholars in light of large amounts of new evidence and new approaches. The handbook suggests new conceptual and methodological tools for researching ancient...

Ökonomen und Politiker gehen heute nicht mehr von einer schnellen Angleichung der wirtschaftlichen Leistungsfähigkeit zwischen Ost- und Westdeutschland aus. In der Tat zeigen viele aktuelle Studien, dass regionalökonomische Unterschiede sehr persistent, also kaum veränderbar sind. Dieser...

Piracy in international waters is on the rise again, in particular off the coast of Somalia. While the dynamic game between pirates, ship-owners, insurance firms and the military seems to have reached some kind of equilibrium, piracy risks generating significant negative externalities to third...

We estimate the parameters of a dynamic, forward-looking neighborhood choice model in 197 metro areas where households have preferences over the racial composition of neighborhoods. Our inclusion of multiple metro areas in the estimation sample enables us to develop a new, shift-share IV...

In this paper, I follow the development of the classification scheme discussions closely through its formative decade, from the last years of the 1890s through about 1913, by which time three revealing publications close the prewar developments: the United States Immigration Commission's massive...

This paper proposes a method to decompose earnings inequality into a component due to unequal opportunities and a residual term. Drawing on the distinction between 'circumstance' and 'effort' variables in John Roemer's work on equality of opportunity, we associate inequality of opportunities...

The Blinder-Oaxaca decomposition technique is widely used to identify and quantify the separate contributions of group differences in measurable characteristics, such as education, experience, marital status, and geographical differences to racial and gender gaps in outcomes. The technique...

We explore how umpires' racial/ethnic preferences are expressed in their evaluation of Major League Baseball pitchers. Controlling for umpire, pitcher, batter and catcher fixed effects and many other factors, strikes are more likely to be called if the umpire and pitcher match race/ethnicity....
