Joachim Prinz Bücher

Joachim Prinz (1902–1988) was one of the most extraordinary and innovative figures in modern Jewish history. Never one for conformity, Prinz developed and modeled a new rabbinical role that set him apart from his colleagues in Weimar Germany. Provocative, strikingly informal and determinedly anti-establishment, he repeatedly stirred up controversy. During the Hitler years, Prinz strove to preserve the self-respect and dignity of a Jewish community that was vilified on a daily basis by Nazi propaganda. After immigrating to the United States in 1937, he soon became a prominent rabbi in New Jersey, drawing thousands to his unpredictable sermons. Prinz's autobiography, superbly introduced and annotated by Michael A. Meyer, offers a fascinating glimpse into the life and personality of this unconventional and influential rabbi.

One of the most stylized facts in labor economics is the finding that wages tend to rise with job duration but what is the role of productivity between this relation? Intuitively, it seems rather unspectacular that experienced workers' earnings are higher than otherwise comparable junior workers', but economic literature offers three competing theories explaining this phenomenon. A unique database from a single professional sports industry, covering the past decade of player performance and wages in the National Basketball Association (NBA) is used to test the superiority of one model over others in explaining players' upwards sloping age-earnings profiles. The empirical results show little evidence of the notion that player wages are solely determined on the basis of their productivity. Findings are rather in accordance with shirking and matching ideas: Returns to tenure are found to be significant but it's magnitude is reduced when the spurious bias - stemming from OLS - is controlled for. The fact that tenure remains considerably large - unaffected of productivity - but is simultaneously mitigated due to job match specific effects, is in harmony with incentive and matching arguments.
