Evaluation Periods and Asset Prices in a Market Experiment 总被引:6,自引:0,他引:6
We test whether the frequency of feedback information about the performance of an investment portfolio and the flexibility with which the investor can change the portfolio influence her risk attitude in markets. In line with the prediction of myopic loss aversion (Benartzi and Thaler (1995)), we find that more information and more flexibility result in less risk taking. Market prices of risky assets are significantly higher if feedback frequency and decision flexibility are reduced. This result supports the findings from individual decision making, and shows that market interactions do not eliminate such behavior or its consequences for prices. 相似文献

The dynamics of biomass growth implies that the yield of irrigated crops depends, in addition to the total amount of water applied, on irrigation scheduling during the growing period. Advanced irrigation technologies relax constraints on irrigation rates and timing, allowing us to better adjust irrigation scheduling to the varying needs of the plants along the growing period. Irrigation production functions, then, should include capital (or expenditures on irrigation equipment) in addition to aggregate water. We derive such functions and study their water-capital substitution properties. Implications for water demand and adoption of irrigation technologies are investigated. A numerical example illustrates these properties. 相似文献

The doctrine of relative purchasing power parity during periods of fixed and flexible exchange rates is investigated. Using cointegration techniques and data for the Group of Seven countries, a subset of the results suggests, that purchasing power parity held only between the United States and the United Kingdom over the period 1957 QI to 1973 QII. Different results are obtained for the 1973 QIII to 1990 QIV period. Based on the maximum likelihood approach of Johansen and Juselius and an error correction model, it is concluded that purchasing power parity held between the United States and Canada, the United States and France, the United States and Italy, and the United States and the United Kingdom. 相似文献

Target prices,market prices,and economic efficiency in agriculture in the United States 总被引:1,自引:0,他引:1

This paper looks at one aspect of current United States agricultural policy. This concerns the attempt by the federal government to support commodity prices and income of farmers. This is accomplished through the deficiency payments program. Unfortunately, the program is inherently economically inefficient. Moreover, alternatives (short of eliminating the program altogether and not replacing it) also are not economically efficient.

Zusammenfassung In der amerikanischen Agrarpolitik spielen Preis- und Einkommenssubventionen für Farmer eine wichtige Rolle. Der Beitrag behandelt die Wirkungen des seit 1985 bestehenden Systems von Ausgleichszahlungen für landwirtschaftliche Erzeugnisse. Diese Zahlungen errechnen sich als Differenz zwischen dem Subventionspreis für ein bestimmtes landwirtschaftliches Erzeugnis und seinem Marktpreis.Die bei den Landwirten eintretenden Wirkungen sind meist positiv, hingegen werden die Konsumenten bei Lebensmitteln mit Preiserhöhungen belastet. Seit die Marktpreise in den USA über den Weltmarktpreisen liegen, sind zusätzliche staatliche Subventionen notwendig, um landwirtschaftliche Erzeugnisse auf dem Weltmarkt verkaufen zu können. Auch dafür werden die Konsumenten in ihrer Rolle als Steuerzahler belastet. Die Kosten des Systems betragen für jeden Steuerzahler jährlich etwa 413$.Die Ausgleichszahlungen führen zu Verzerrungen bei wirtschaftlichen Anreizen und dadurch zu einer Fehlallokation von Ressourcen. Deshalb wird diese Politik vom Autor als ineffizient beurteilt. Er diskutiert Alternativen, die darauf abzielen, die gewünschten politischen Ziele zu erreichen. Doch keine dieser Alternativen geht ernsthaft das Problem der wirtschaftlichen Ineffizienz an, das mit Subventionen verbunden ist.

The analysis in this paper is directed at measuring the substitution between seven beverages consumed in the United States with the objective of shedding some light on just what is the relevant market for antitrust purposes. With regard to the overall beverage market considerations, there is a clear indication that consumers do substitute between different types of beverages. What must be subjectively resolved, however, is whether the extent of the indicated substitution is of significant enough magnitude to infer that two different beverages are in the same product market. 相似文献

It is acknowledged[Weinstein, N. and Nicolich, M. (1993) ‘Correct and Incorrect Interpretations of Correlation Between Risk Perceptions and Risk Behaviours’, Health Psychology, Vol. 12, No. 3, pp. 235–45.] that with the development of services marketing specifically related to health services comes a need to understand the aspects of consumer risk behaviour. This paper examines differences in perceived risk between health services, general services and goods and will seek to substantiate and develop a previous US study,[Murray, K. B. and Schlacter, J. L. (1990) ‘The Impact of Services Versus Goods on Consumer's Assessment of Perceived Risk and Variability’, Journal of the Academy of Marketing Science, Vol. 18, No. 1, pp. 51–65.] utilising a quantitative methodology with repeated measures and nested factors. The conclusions support the hypotheses that there are significant differences in perceptions of social and psychological risks when purchasing health services.
