Gibrat’s Law (GL) has repeatedly failed to gain full empirical confirmation in specific industries. This study offers a deliberately
favorable opportunity for full confirmation in the truckload sector of the U.S. trucking industry where firms are highly homogeneous.
As such, most nonrandom determinants of growth remain very similar for all firms, so significant differences in growth rates
are not expected. Still, there is only incomplete support: (1) long term growth rates are not equal for all firms, but the
differences are small and not size-related except for the smallest firms, and (2) the size distributions better approximate
lognormal when the smallest firms are excluded, but in no case does the variance rise over time. This suggests that for most
other industries, where nonrandom growth should be much stronger, GL would seem unlikely to play more than a minor role in
portraying actual firm growth or the evolution of market structure. 相似文献

Merton Miller's (1977) tax model of equilibrium capital structure choice results in capital structure irrelevance and the
existence of tax clienteles, assuming the restrictive case of risk-neutrality. Relaxation of the assumption of risk-neutrality
in Miller's tax framework, allowing utility-maximizing risk-averse investors, indicates that capital structure irrelevance
continues to hold under reasonable assumptions about utility. Evaluation of resulting tax clienteles shows that marginal tax
rates do not restrict investors from investing in equities but do affect the tax status of purchased bonds. 相似文献

Real exchange rate behavior 总被引:1,自引:0,他引:1
Using random simulations with artificial data with identical sample characteristics to the long-sample exchange rate data employed by Lothian and Taylor (Lothian, J.R. and Taylor, M.P. (1996). The recent float from the perspective of the past two centuries. Journal of Political Economy 104, 488–509.), we show that standard unit-root tests have extremely low power over sample sizes corresponding to the recent float. The probability of rejecting the null hypothesis when it is false is extremely low with 20 years or even 50 years of data and only reaches an acceptable level over much longer spans. 相似文献

Water conflicts are intensifying as the population grows in the American West. Stakeholders seek a better understanding of households’ water knowledge, preferences, and willingness to pay (WTP) as they contemplate various water allocation initiatives. An Internet survey provides insight into western households’ perceptions and preferences regarding water use and management, their familiarity with water terminology, and their WTP a fee in support of eight potential water initiatives regarding water acquisition, conservation, and reallocation. Further analysis identifies factors that influence the decision. Just over half of all respondents express a WTP the fee, with an estimated median WTP among survey respondents of $15.65 per summer month. Respondents with higher self-reported water knowledge are more likely to support the fee. The probability of supporting the fee is also influenced by respondents’ demographic characteristics and attitudes toward water scarcity and management. Les conflits liés à l’eau s’intensifient à mesure que la population s’accroît dans l’Ouest américain. Les parties prenantes cherchent à découvrir les connaissances sur l’eau, les préférences et le consentement à payer des ménages étant donné qu’elles envisagent divers schémas d’allocation de l’eau. Un sondage en ligne a donné un aperçu des perceptions et des préférences des ménages de l’Ouest américain concernant l’utilisation et la gestion de l’eau, de leur degré de connaissance de la terminologie de l’eau et de leur consentement à payer une taxe pour appuyer huit projets éventuels d’acquisition, de conservation et de réallocation de l’eau. Une analyse plus détaillée a déterminé les facteurs qui influençaient les décisions. Un peu plus de la moitié des répondants ont indiquéêtre prêts à payer une taxe. Chez les répondants, le consentement à payer médian s’élevait à 15,65 $ par mois durant la saison estivale. Les répondants qui ont indiqué avoir de bonnes connaissances sur l’eau sont plus susceptibles d’appuyer l’imposition d’une taxe. Les caractéristiques démographiques et les attitudes des répondants envers la rareté et la gestion de l’eau influencent la probabilité d’appuyer l’imposition d’une taxe. 相似文献

This article deals with the problem of item nonresponse in contingent valuation surveys using a payment-card method, by applying a grouped-data sample-selection estimation technique that is capable of imputing the missing values conditional upon a respondent's decision to answer a willingness-to-pay question. The advantage of the technique lies in its ability to utilize all of the information in the sample, permitting a more efficient estimation in the presence of item nonresponse bias. The major determinants of willingness to pay appear to be household income, number of children, education, perception of existing water quality, and identification with environmental issues. 相似文献

This paper looks at the policy debate surrounding private pensions and retirement patterns in the UK. Recent increases in longevity have led not only to increased pressures in public pensions but also to corresponding increases in the importance of private pensions in the UK and changes in the way in which they are structured. We consider the economic implications of these changes, and in particular the increased importance of defined contribution plans. In addition, we discuss the prospects for future trends in retirement ages. 相似文献

Experimental analysis of choice 总被引:2,自引:1,他引:2

Experimental choice analysis continues to attract academic and applied attention. We review what is known about the design, conduct, analysis, and use of data from choice experiments, and indicate gaps in current knowledge that should be addressed in future research. Design strategies consistent with probabilistic models of choice process and the parallels between choice experiments and real markets are considered. Additionally, we address the issues of reliability and validity. Progress has been made in accounting for differences in reliability, but more research is needed to determine which experiments and response procedures will consistently produce more reliable data for various problems.Sawtooth SoftwareDecision Research 相似文献

This study uses data from the automotive replacement tire industry to test the proposition that dependence and relationship structure interact to determine frequency of influence-strategy use in distribution systems. The findings support the expectation that dependence is positively associated with recommendations, information exchanges, promises, requests, legal pleas, and threats. However, increases in dealer dependence increase the use of requests, legal pleas, and threats only in systems characterized by trivial levels of relationalism.The authors would like to express their gratitude to John Burnett, Robert Dwyer, Jule Gassenheimer, and Allen Wilhite for their helpful comments on this project. 相似文献
