Accumulating Knowledge over the Economist's Lifetime
研究了经济学家的阅读行为，发现对前沿文献的投资每年下降3%至6%，而应用知识投资保持不变；数学经济学家起初回避但12-15年后赶上；机构激励和研究生培养模式也影响阅读选择。
In this paper, the reading behavior of economists is examined to see whether different types of knowledge imply different investment patterns. The investment in advanced literature declines with 3 to 6 percent per year. Investment in applied knowledge remains constant over time. Mathematical economists initially back away from this literature but catch up with economists in twelve to fifteen years time. Besides the nature of knowledge, institutional incentives matter. Business and government economists concentrate on applied literature and researchers on advanced literature. The introduction of an American-style of graduate training has led graduates to turn away from locally applied literature. Copyright 1998 by WWZ and Helbing & Lichtenhahn Verlag AG
