Previous studies typically find a statistically insignificant relation between the market risk premium and its expected volatility. Further, several of these studies estimate a negative risk return tradeoff, contrary to the predictions of mainstream theory. Using simulations, I demonstrate that even 100 years of data constitute a small sample that may easily lead to this finding even though the true risk return tradeoff is positive. Small-sample inference is plagued by the fact that conditional volatility has almost no explanatory power for realized returns. Using the nearly two century history of U.S. equity market returns from Schwert [1990. Indexes of United States stock prices from 1802 to 1987. Journal of Business 63, 399–426], I estimate a positive and statistically significant risk return tradeoff. Finally, exploratory analysis suggests a role for a time-varying relation linked to the changing nature of the U.S. economy. 相似文献

An input–output (IO) system which is capable of producing any semi-positive net product by an adequate choice of the activity levels of its processes satisfies the ‘adjustment’ property. We analyze under which conditions the adjustment property holds for IO systems in which some produced goods have a purely intermediate character. The peculiarity of these pure capital goods is that final demand for them is identically zero. One of the ways to deal with this type of system is to eliminate the pure capital goods, by means of vertical integration. 相似文献

We show how to construct models of the term structure of interest rates in which the expectations hypothesis holds. McCulloch (1993) presents such a model, thereby contradicting an assertion by Cox, Ingersoll, and Ross (1981), but his example is Gaussian and falls outside the class of finite-dimensional Markovian models. We generalize McCulloch's model in three ways: (i) We provide an arbitrage-free characterization of the unbiased expectations hypothesis in terms of forward rates; (ii) we extend this characterization to a whole class of expectations hypotheses; and (iii) we show how to construct finite-dimensional Markovian and non-Gaussian examples. 相似文献

The aim of the present study is to examine the role of ethical dimensions and product personality in the purchasing intention
of organic food products. The Prospect method (Caprara et al. in Test Psicomet Metodol 7(3–4):113–128, 2000), which integrates the Five factors model of personality (cf. Digman in Annu Rev Psychol 41(1):417–440, 1990) and the Theory of planned behavior (Ajzen in Organ Behav Hum Decis Process, 50(2):179–211, 1991) extended to an ethical dimension, was employed, by using a Structural Equation Modeling approach. Results showed that moral norms—i.e., personal beliefs regarding what is right or wrong (Parker et al. in Br J Soc Psychol, 34(2):127–137, 1995)—can be considered the main motivator of purchasing intention, and they are, in turn, affected by subjective norms and product personality traits of Naturalness and Authenticity. Marketing implications for firms operating in the organic food industry are discussed, in their intent to shift from a “niche”
market to a broader diffusion of these products. 相似文献

This paper presents the results from an auction experiment using industry professionals and student participants who compete
in a simulated wholesale market for electricity. Motivated by the intervention by FERC in response to the “meltdown” of the
California spot market, we investigate the effect of including a “soft” price cap in a uniform price auction as a means of
mitigating high prices. When prices are driven above the soft cap, offer curves become flat, in contrast to the hockey stick
shape observed in a typical uniform price auction for electricity. This flat offer curve leads to market prices that are relatively
insensitive to both generation costs and demand reductions.

Knowledge spillovers from a university to the local industry play an important role in high-technology clusters, but we know little about these spillovers. This paper examines empirically the extent of informal contacts between employees in firms and local university researchers in a wireless communications cluster. Furthermore, it analyses the features of an engineer who acquires knowledge from these informal contacts. The university–industry contacts are compared to results for informal contacts between employees in firms. The research shows that the interfirm informal contacts are more numerous than university informal contacts. Likewise, knowledge is more frequently acquired from engineers in other firms than through university–industry contacts. However, not all engineers in the cluster have informal contacts or acquire knowledge through these. Engineers who have participated in formal projects with university researchers and engineers who are educated at the local university have a higher likelihood of acquiring knowledge from informal contacts with university researchers. 相似文献

Zusammenfassung Strategische Vorhaben werden zunehmend in Form von Projekten umgesetzt. Daher ist aus Sicht der Unternehmensführung
ein besonderes Augenmerk auf die Auswahl, Bewertung und Kontrolle dieser strategischen Projekte zu legen.
Es wird die Bildung von Projektportfolios empfohlen, um die Steuerungskomplexit?t zu verringern. Aus
konzeptioneller Sicht ist das Multiprojektmanagement für die Lenkung dieser Projektportfolios verantwortlich.
In der Literatur werden dabei unterschiedliche Organisationseinheiten diskutiert, die typischerweise im
Multiprojektmanagement involviert sind. Die Erkenntnisse einer empirischen Untersuchung zum Einfluss bzw.
zur Mitwirkung dieser Organisationseinheiten in 75 deutschen Gro?unternehmen zeigen, dass je nach Aufgabengebiet
sowohl die Unternehmensleitung als auch Portfolio-Boards und Multiprojektmanager in hohem Ma?e beteiligt
sind.
Exertion of influence and involvement of organisational units in Multi-Project-Management
Summary Strategic intentions are increasingly transferred into action in the form of projects. Because of this the corporate management has to pay attention particularly to the selection, the valuation and the control of these strategic projects. To decrease the complexity of steering, it is recommended to establish portfolios of projects. Seen from a conceptual perspective the multi-project-management is responsible for guidance of these project-portfolios. In this context literature discusses several organisational units which are typically involved in multi-project-management. The results of an empirical study in 75 German large-scale enterprises concerning the exertion of influence and involvement of organisational units in multi-project-management suggest that depending on the assignment corporate management as well as portfolio-boards and multi-project-managers are involved to a high degree.相似文献
