Freedman (economics, U. of New South Wales, Australia) and Szostak (economics, U. of Alberta, Canada) present 18 previously published papers in which economists question some of the basic assumptions of their field, sometimes directly and sometimes indirectly. There is not much cohesion among the papers, which address the topic from a range of perspectives and with a variety of approaches. Annotation (c)2003 Book News, Inc., Portland, OR
