While college enrollment has more-than doubled since 1970, elite colleges have barely increased supply, instead reducing admit rates. We show that straightforward reasons cannot explain this behavior. We propose a model where colleges compete on prestige, measured using relative selectivity or...

We construct a model of simultaneous change and persistence in institutions. The model consists of landowning elites and workers, and the key economic decision concerns the form of economic institutions regulating the transaction of labor (e.g., competitive markets versus labor repression). The...

This paper studies how exclusive social groups shape upward mobility, and whether interactions between low- and high-status peers can integrate the top rungs of the economic and social ladder. Our setting is Harvard in the 1920s and 1930s, where new groups of students arriving on campus...

Leadership positions in the U.S. are disproportionately held by graduates of a few highly selective private colleges. Could such colleges -- which currently have many more students from high-income families than low-income families -- increase the socioeconomic diversity of America's leaders by...

Over the last twenty years the wage-education relationships in the US and Germany have evolved very differently, while the education composition of employment has evolved in a surprisingly parallel fashion. In this paper, we propose and test an explanation to these conflicting patterns. The...

Is the expansion of jobs in low-wage services in Europe restricted by high wages? With services now the main sector source of employment growth this question becomes crucial and we examine it through a detailed comparison of the role of low-wage services in the US and Germany. We find a clear...

Germany's more compressed wage structure is taken by many analysts as the main cause of the German-US difference in job creation. We find that the US has a more dispersed level of skills than Germany but even adjusted for skills, Germany has a more compressed wage distribution than the US. The...
