It has been widely argued that the purpose of corporate restructuring during the 1980s was to produce a population of more industry-specialized, competitive firms in response to intensifying global competition. A number of studies show that corporate restructuring resulted in increased corporate focus during the 1980s. However, no study has yet examined whether corporate restructuring resulted in increased specialization at the industry level during the 1980s. This study examines this issue. First, we examine whether or not aggregate industry specialization increased during the 1980s. That is, we ask: did the average firm in any given U.S. industry become more or less specialized to that industry during the 1980s? Second, we examine whether corporate restructuring was a significant determinant of change in aggregate industry specialization during the 1980s. Using a sample of 686 four-digit SIC industries and 64 two-digit industry groups, this study finds that aggregate industry specialization declined very slightly at both the four-digit and two-digit level between 1981 and 1989. This study also finds that sell-offs of establishments through corporate control transactions or interfirm asset sales had no significant effect on aggregate industry specialization.  相似文献

Studies of consumer usage of nutrition labels required by the Food and Drug Administration have found that usage levels are low. A mailback survey of food shoppers in Madison, Wisconsin was conducted to determine who uses nutrition labels as well as reasons for nonuse. Multiple regression analysis revealed that compared to users, nonusers did not rate themselves as highly on nutrition knowledge, were less likely to plan meals in advance, and were not as highly educated. When asked why they did not use labels, most nonusers said they did not need them, and a sizable group reported their shopping practices pre-empt label usage. Nonusers also felt that a sample label had too much information. When asked to perform computations from sample label information, nonusers were less successful than users. The implications of these findings for nutrition education efforts are discussed.  相似文献

In 1998, 46 states were involved in a Master Settlement Agreement (MSA) with the tobacco industry. The other four states settled on their own. Our goal is to answer a counter factual question: how would these four states have fared had they been included in the MSA? We use data from Viscusi (2002 Viscusi WK (2002) Smoke‐Filled Rooms Chicago University of Chicago Press  [Google Scholar]) to explain settlement shares for states participating in the 1998 tobacco MSA, and to predict settlement shares for the four nonparticipating states. We find that two nonparticipating states (Minnesota and Mississippi) may have fared substantially worse had they been included in the MSA.  相似文献
