On the Rich Getting Richer and the Poor Getting Poorer
检验了“富者愈富、贫者愈贫”这一论断的有效性，发现其缺乏实证支持，因为收入阶层间存在大量流动，且该论断忽视了创业精神在动态经济中的作用。
This paper evaluates the validity of the thesis of 'the rich getting richer and the poor getting poorer' (RGR) and finds it wanting. Its implication of increasing polarization of income and wealth distribution is not borne out by observation. There is too much mobility across income strata to be consistent with RGR. The idea of RGR rests on a faulty understanding of the way the market economy works. The fault lies in taking a static view of a dynamic economy and ignoring the dynamo, viz., entrepreneurship. The essence of entrepreneurship is not the ownership of currently valued assets but the discovery of opportunities. Copyright 1999 by WWZ and Helbing & Lichtenhahn Verlag AG
