Exploring the expectations of transport professionals concerning the future automobility system: Visions,challenges, and transitions

A mixture of potentially significant changes in technology, commercial structures, and social practices is currently entering the automobility system. These changes have the potential to combine together and lead to a substantial shift in the manner in which society fuels, owns, and makes use of its cars. This paper reports a research project that made use of focus groups to examine the narratives of British transport professionals concerning forthcoming developments in the automobility system. Specific attention was given to what the expectations for future change in automobility are, if these changes will likely lead to a transition toward a more sustainable system and the manner in which a transition of this nature could be facilitated. The oral testimony offered during the focus groups has been assessed qualitatively using thematic analysis. The results suggest that there is a commonly held view that the automobility system is entering a stage of flux, which may lead to considerable changes in system configuration. However, the attainment of a sustainable transition for the system will likely be inhibited by a series of institutional, societal, and physical barriers, which may restrict system developments.     

Some Teaching Techniques for High School Economics

In this article two high school economics teachers describe several teaching techniques that have proven successful in their school. The use of a team approach is briefly explained, and the importance of student motivation is stressed. Among the methods included are skits, plays, the use of video tapes, simulations and games, and the analysis of important economic problems. The means by which the instructors are evaluating their course are set forth, with evidence that the experience helps to destroy commonly held myths about economics and greatly improves student understanding of basic principles.     

Social Status,Entry and Predation: The Case of British Shipping Cartels 1879–1929

The authors incorporate social status and regional affiliation—two variables of central sociological interest—into an economic analysis of entry and predation. They build on Scott Morton’s [1997] examination of entry and predation in the merchant shipping industry and examine whether the social status of an entrant owner impacts on the predation behavior of the incumbent cartels. They find that high social status entrants are significantly less likely (40%) to be preyed upon than the low social status entrants. They discuss several interpretations of this result. Subsequent analysis supports the hypothesis that cartel members use social status as an indicator of an entrant’s propensity to be a cooperative cartel participant.     

Investor Overreaction to Earnings Surprises and Post‐Earnings‐Announcement Reversals

Prior literature suggests that the market underreacts to the positive correlation in a typical firm's seasonal earnings changes, which leads to a post‐earnings‐announcement drift (PEAD) in prices. We examine the market reaction for a distinct set of firms whose seasonal earnings changes are uncorrelated and show that the market incorrectly assumes that the earnings changes of these firms are positively correlated. We also document that positive (negative) seasonal earnings changes in the current quarter are associated with negative (positive) abnormal returns in the next quarter. Thus, we observe a reversal of abnormal returns, consistent with a systematic overreaction to earnings, rather than the previously documented PEAD. Additional analysis indicates that financial analysts similarly overestimate the autocorrelation of these firms, although to a lesser extent. We also find that the magnitude of overestimation and the subsequent price reversal are inversely related to the richness of the information environment. Our results challenge the notion that investors recognize but consistently underestimate earnings correlation and provide a new perspective on the inability of prices to fully reflect the implications of current earnings for future earnings. That is, we show that investors predictably overestimate correlation when it is lacking, but underestimate it when it is present.     

Love or Money? The Effects of Owner Motivation in the California Wine Industry

Models that assume only consumer tastes determine the characteristics of supply are restrictive; producers can gain utility from aspects of production and pay for deviating from demand by accepting lower financial returns. We model and measure motivations of California winery owners, and analyze their effects on quality and price. We find utility–maximizers are more likely to produce high quality and set higher quality–adjusted prices. Profit–oriented owners are less likely to produce high quality wines. These results suggest that the presence of hobbyists who enjoy producing high quality may lower financial returns in the segment and discourage profit–maximizers from locating there.     

The Latin Melting Pot Is Boiling Over

A bstract . During the 1970s no area contributed more immigrants to the United States, both legal and illegal, than Latin America. The Latin American population in the U.S. has become the country's fastest growing large minority and unless economic conditions in Latin America improve for its poorer population, these people will continue to enter the U.S. in large numbers. The chaotic social situation in the country's Latin ghettos highlights a grave national problem. A. J. Jaffe, R. M. Cullen and T. D. Boswell of the Research Institute for the Study of Man completed a study of this immigration which deserves far greater attention than it has received. They found that cultural convergence of Latins with the non-Latin White population varied by subgroup, and was heavily dependent upon the volume of immigration of a particular subgroup and the degree of their concentration in this country.
