This article operationalizes a non-empty relation as implied if strict preference and indifference jointly do not completely order the choice set. Specifically, indecision is operationalized as a positive preference for delegating choice to a least predictable device.  相似文献

Using an overlapping generations model in which human capital accumulation has positive external effects on the production of the human capital of future generations, this paper analyzes implications of agents’ having preferences for educational status, represented by human capital holdings relative to the social average. Examining the value and sign of the optimal distortionary tax in the optimal taxation scheme, we analyze the efficiency of the level of human capital accumulation in a decentralized economy. The desire for educational status can compensate for insufficient accumulation of human capital stemming from human capital externalities directed toward future generations.  相似文献

Abstract

The loss of community and of traditional communal ties characteristic of modern industrial society has caused many people to search for alternative sources of social identification and solidarity. Recreational sites may afford some people opportunities for constructing communities on the basis of common interests. As part of an ongoing investigation, data have been gathered over several years to discover whether elements of community can be found in a marina's social system; evidence is being sought through examination of patterns of social interaction, the system of social ranking, and ties of affection that characterize the marina's social network. Data reveal a social organization at the marina comprising subgroups with complex interaction patterns, affective ties, and communal solidarity. It appears, therefore, that at this recreational site the structure and dynamics of an alternative form of community have been constructed by boaters.  相似文献

Spanish steelmaking policy in the 1970s and early 1980s was not especially different from that of the main European countries. The political transition was a tense experience that heightened the problems and made economic policy decisions harder to reach, but it did not cause a fundamental divergence from the rest of Europe. What made the steel restructuring policy fail and forced a new and costly restructuring in the 1990s, was the decision of the Socialist government, newly elected in 1982, to opt for maintaining the inland steelworks instead of the coastal steelworks. Its motives were related to the locations of these steelworks in socially and politically sensitive areas. The closure of Sagunto marked the end of the only real possibility of Spain having a competitive integrated steelworks in terms of its integration into Europe.  相似文献

In this second of two articles on strategic marketing planning the author describes the techniques that have been developed to aid analysis of marketing information. Analytical frameworks such as the product life‐cycle, the growth‐share matrix, the Business Assessment Array and the Directional Policy Matrix are discussed and the benefits and pitfalls associated with strategic planning frameworks are considered by the author.  相似文献

Abstract

Views on the preservation of resources versus their development for recreation are compared among participants in three types of outdoor recreation: “appreciative”; activities (cross‐country skiing, hiking, and canoeing); “consumptive”; activities (fishing and hunting); and “mechanized”; activities (motorboating, snowmo‐biling, and trail biking). The results from a 1984 questionnaire survey conducted in Edmonton and Calgary, Canada, indicate a stronger preservationist orientation among participants in appreciative activities, whereas (with the exception of hunters) participants in consumptive and mechanized activities hold stronger pro‐development views. These differences cannot be attributed to simultaneous variations in socioeco‐nomic characteristics or environmental attitudes among the recreational groups. The findings suggest that differences in outdoor recreational activity preferences represent an important source of variation in views about appropriate levels of preservation versus development of Alberta's natural and wildernesss resources.  相似文献
