The theory proposed in ‘An Examination of Residential Mobility Through The Use of The Log- Linear Model, Part I’, Regional Science and Urban Economics (1978) Vol. 8, No. 2, is illustrated by analysing data obtained on moving households in an urban area. 相似文献

Role models can be highly influential in conveying ethical standards. This study investigates the influence various categories
of role models have had on a population of over 1,600 undergraduate students in Texas, Oregon and Michigan. Those identifying
clergy, boy scout leaders, friends and college advisors as role models exhibited less willingness to adopt questionable ethical
behavior in negotation situations. Journalist and spouse role models tended to cause students to be more accepting of questionable
behavior. Individuals with strong end-result and social contract ethical philosophies, as well as males and those who served
in the military exhibited strong tendencies toward less than ethical behavior. Individuals with strong rule ethical philosophy,
high levels of religiousity, and those with a cooperative attitude in negotiations tended to adopt higher ethical standards
in negotiations. 相似文献

One of the new ways used by companies to demonstrate their social responsibility is to encourage employee volunteering, whereby
employees engage in socially beneficial activities on company time, while being paid by the company. The reasoning is that
it is good for employee motivation (internal effects) and good for the company reputation (external effects). This article
reports an empirical investigation of the internal effects of employee volunteering conducted amongst employees of the Dutch
ABN-AMRO bank. The study showed that (a) socio-demographic characteristics from employee volunteers markedly differ from those
of non-volunteers and community volunteers and (b) employee volunteering seems to have positive effects on attitudes and behavior
towards the organization. 相似文献

On the pricing of forward starting options in Heston’s model on stochastic volatility 总被引:2,自引:0,他引:2
We consider the problem of pricing European forward starting options in the presence of stochastic volatility. By performing a change of measure using the asset price at the time of strike determination as a numeraire, we derive a closed-form solution within Hestons stochastic volatility framework applying distribution properties of the volatility process. In this paper we develop a new and more suitable formula for pricing forward starting options. This formula allows to cover the smile effects observed in a Black-Scholes environment, in which the extreme exposure of forward starting options to volatility changes is ignored.Received: July 2004, Mathematics Subject Classification (2000):

Preexisting distortions in factor markets complicate the estimation of the social welfare effects of regulatory interventions. The existence of these tax interaction effects (TIEs) suggests that general equilibrium (GE) approaches should be used to evaluate regulatory policies. However, formal GE analysis is not always feasible for the numerous environmental regulations proposed by federal, state, and local agencies. The question addressed in this paper is whether an empirically based rule of thumb upward adjustment factor is appropriate to properly scale social cost estimates in environmental policy. We argue that such rule of thumb adjustments are significantly less reliable than estimates based on a detailed general equilibrium analysis because of the uncertainty about both the magnitude and sign of the social cost distortion. In addition to addressing this question, the paper gives an overview of TIEs and their relevance to environmental policy. 相似文献
