The underlying “architecture of the decision to pursue a degree in psychology was quantified using the Method of Sorting technique
to identifying the critical issues necessary to make this choice. Multidimentsional scaling procedures were employed to construct
a three-dimensional map representing the relationships between reasons for selecting psychology as a major. Freshman and senior
psychology majors (N = 165) from a regional university and a large research-based institution rated the relative importance of items in their
decision-making process. Hierarchical clustering procedures revealed seven different groups of students. Although significant
differences associated with class standing were not found, institutional affiliation did influence cluster composition. Reflecting
local emphases, students at the regional institution had a greater interest in Counseling Psychology, whereas those at the
research-based school focused on Clinical Psychology. This semantic map and the associated item clusters arising from psychology
student data provides an empirical basis for, amongst other things, course selection, faculty-initiated program design or
revision, strategic niche marketing, and student retention. 相似文献
Many advertised products are established and have little quality variation. For these products advertising signaling explanations are unconvincing. We develop a coordination model of advertising with consumers observing ads probabilistically and never observing advertising levels. Consumers who fail to see an ad for a product believe it will likely have low sales and so be of low value. Firms advertise to avoid these beliefs. The model's predictions on advertising, market share, and profitability are consistent with observed outcomes. The model produces the time series behavior for prices and market share observed in the data and not available from existing coordination models. 相似文献
This paper examines the case of a good, polluting in consumption, whose pollutive content is restricted by a government with strong environmental policies. When foreign producers are unable to comply with the restrictive environmental standard of such a country, to which they wish to export, they often allege that those standards constitute illegal barriers to free trade. An example of such a good is gasoline, excessively pollutive formulations of which are prohibited from importation into the United States by the 1970 Clean Air Act. Rather than banning them, such imports should be taxed, along with the domestically produced substitute good, according to their respective pollutant contents. This would foster economic efficiency and should be more acceptable to foreign producers than the outright prohibition mandated by the Clean Air Act. The results of this paper reaffirm the argument in a previous article in this journal (Socio-Economic Planning Sciences 29 (1995) 187), though the countries’ roles in the two papers are reversed, that free trade and Pigouvian environmental policies increase international welfare. 相似文献
We show that the Hotelling–Lau elasticity of substitution, an extension of the Allen–Uzawa elasticity to allow for optimal
output-quantity (or utility) responses to changes in factor prices, inherits all of the failings of the Allen–Uzawa elasticity
identified by Blackorby and Russell [(1989) Am Econ Rev 79: 882–888]. An analogous extension of the Morishima elasticity of
substitution to allow for output quantity changes preserves the salient properties of the original Hicksian notion of elasticity
of substitution.

Realized variance, being the summation of squared intra-day returns, has quickly gained popularity as a measure of daily volatility. Following Parkinson [1980. The extreme value method for estimating the variance of the rate of return. Journal of Business 53, 61–65] we replace each squared intra-day return by the high–low range for that period to create a novel and more efficient estimator called the realized range. In addition, we suggest a bias-correction procedure to account for the effects of microstructure frictions based upon scaling the realized range with the average level of the daily range. Simulation experiments demonstrate that for plausible levels of non-trading and bid–ask bounce the realized range has a lower mean-squared error than the realized variance, including variants thereof that are robust to microstructure noise. Empirical analysis of the S&P500 index-futures and the S&P100 constituents confirms the potential of the realized range. 相似文献
Summary A survey of rationing in micro theories of macroeconomics is presented. The survey starts with a closed economy with money and inventories, which consists of a representative household, a firm and government. After a discussion of the notional demands and supplies and the properties of the Walrasian equilibrium, a discussion of the effective demands and supplies leads to an analysis of the four regimes (Keynesian unemployment, classical unemployment, repressed inflation and underconsumption). A fiscal and monetary contraction decreases sales and employment when there is Keynesian unemployment, but is expansionary (neutral) when there is repressed inflation (classical unemployment). The survey continues with an analysis of the effects of rationing in a small open economy. It considers the one-sector model and a model with a traded and a nontraded sector. The latter model is used to discuss the effects of an oil discovery on the Gulf countries and on Latin American countries. The survey ends with a discussion of rationing in dynamic economies, which leads to an analysis of the effects of expectations about future constraints on current regimes and to a discussion of boot-strap equilibria.The author is Director of the Network for Quantitative Economics. This paper is a brief and eclectic survey of rationing models of closed one-period and two-period economies and of small open economies. It contains no significant new material. The author is grateful to Professor Theo van de Klundert for his constructive comments on an earlier version of this survey. 相似文献

This paper discusses the impact of a redistribution of current income from the White to the Black population on the distribution of sectoral output, and total employment by means of a semi‐closed input‐output model.
The results show that a redistribution of current income towards Black households — which no doubt will have positive social and political repercussions — has a non‐negative effect on GDP and a definite positive effect on the performance of sectors with a high private consumption expenditure component, as well as on total employment. 相似文献
This research examines the effect of an alliance competence on resource-based alliance success. The fundamental thesis guiding
this research is that an alliance competence contributes to alliance success, both directly and through the acquisition and
creation of resources. Using survey data gathered from 145 alliances, empirical tests of the hypotheses provide support for
the posited explanation of alliance success. The findings indicate that an alliance competence is not only antecedent to the
resources that are necessary for alliance success but also to alliance success itself.
