Gr 5-7-These titles introduce important aspects of the U.S. economy. Seidman defines and explains the basic principles and discusses how they are influenced by the actions of producers and consumers, how supply and demand interact in a large-scale economy, the effects of producer controls on supply, and the role of supply and demand in creating overall economic conditions such as recession and inflation. Wilson explains how distribution of goods and services occurs and describes the importance of retailing and wholesaling in a large economy. He also discusses how different types of transportation affect the prices and availability of goods, explains how services are distributed, and speculates on how the Internet will change retailing and distribution in the future. Both titles are clearly and accurately written, with concrete examples that readers will be able to understand. Although these books provide good information, they are not very attractive. The pages are too crowded with text and the few photos are often unrelated to it. On balance, however, these titles are better and more clearly written than some of the other entries in the series, such as Clare Tattersall's Money and Banking and Marie Bussing-Burks's Taxation and Government Spending (both Rosen, 2000).-Mary Mueller, Rolla Junior High School, MO Copyright 2001 Cahners Business Information.
