Cross-section data on secondary level student choices provide evidence on factors influencing the decision to study economics. Such evidence makes a key contribution to the broader debates on why student numbers have been falling in economics and why women are reluctant economists. Greater mathematical aptitude and prior knowledge of the subject influence the decision to study economics, and a significant effect is attributable to relative underachievement in economics. There are also significant peer group and teacher effects. Female students are more likely to study economics when there is a critical mass of women studying the subject. There is a positive role model effect of female teachers—although this does not carry over to the decision to continue with economics at the university.  相似文献

All teachers of economics will be interested in the author's dissection of the industrial organization course into its components. Teachers of this specialty will find this survey particularly useful for its examination of how the major texts treat each of the components.  相似文献

Concerns about consumers’ ability to manage their finances have triggered a range of proposals, including interventions aimed at elementary school students. The goal of these approaches is to improve lifelong economic decision making, but the evidence supporting their efficacy is thin. In this article, the authors discuss the trend toward elementary financial education and propose a framework for developing evidence-based programs. They emphasize the need for understanding the underlying mechanisms that facilitate the translation of student knowledge into the ability to make sound economic decisions over the life course. The framework illustrates the importance of articulating the intended mechanisms and effects of education programs. This focus on mechanisms will not only facilitate the evaluation of individual programs, but also the synthesis of evidence across interventions.  相似文献

We examine the relationship between the administrative enforcement of environmental regulation, ethnic heterogeneity, and other community characteristics in New Jersey and New York. We find that the percentage of non-white population in a community is positively related with administrative penalties imposed on violators. However, penalties are lower in more ethnically diverse communities. This result may be due to the fact that these communities are less likely to coordinate to create solidarity across ethnic groups and demand stronger enforcement.  相似文献

Georgescu-Roegen's work is usually divided into two categories, his earlier work on consumer and production theory and his later concern with entropy and bioeconomics beginning with his 1966 introductory essay to his collected theoretical papers published in the volume Analytical Economics. Most economists usually praise his earlier work on pure theory and ignore his later work which is highly critical of neoclassical economics. Those economists sympathetic to his later work usually take the position that he “saw the light” and gave up neoclassical theory some time in the 1960s to turn his attention to the issues of resource scarcity and social institutions. It is argued here that there is an unbroken path running from Georgescu's work in pure theory in the 1930s, 1940s, and 1950s, through his writings on peasant economies in the 1960s, leading to his preoccupation with entropy and bioeconomics in the last 25 years of his life. That common thread is his preoccupation with “valuation.” The choices our species makes about resource use and the distribution of economic output depends upon our valuation framework. Georgescu-Roegen's work begins in the 1930s with a critical examination of the difficulties with the hedonistic valuation framework of neoclassical economics, moves in the 1960s to the conflict between social and hedonistic valuation, and culminates in the 1970s and 1980s with his examination of the conflict between individual, social, and environmental values. This paper traces the evolution of Georgescu-Roegen's thought about valuation and the environmental and social policy recommendations which arise out of his bioeconomic framework.  相似文献
