This study explores the effects of task structure and leader power on participative leadership across Australian, African, Papua-New Guinea and Pacific Island managers. Managers in all national groups are more participative in situations of low structure and low power than for high structure and high power, respectively. Participation in situations of low structure and low power declines in the order: Australia, Africa, Papua-New Guinea, Pacific Islands. It is argued that this effect is an instrumental effect of managerial education, rather than being culturally determined. the Vroom-Yetton leadership methodology is used to measure participation levels. Subjects are a total of 150 middle-level managers attending management education courses. 相似文献

We study the local turnpike property for two classes of infinite-horizon discrete-time deterministic maximization problems
which have common applications, e.g., optimal growth theory. We follow a functional-analytic approach and rely on an implicit
function theorem for the space of the sequences which converge to zero. We shall assume the existence of an optimal path which
is not necessarily a steady-state. Relying on material developped in Blot and Crettez (Decis Econo Finance 27:1–34, 2004),
“On the smoothness of optimal paths” Decis Econ Finance, 21:1–34, 2004), we provide conditions under which a variation in
the initial conditions (i.e., capital stock and discount rate) yields an optimal solution which converges toward a reference
solution when time becomes infinite. We also provide new results on bounded solutions of difference equations.
We gratefully thank the editor, Silvano Holzer, and two anonymous referees for remarks and advices on a previous version of
this paper. 相似文献

In this paper, progressive stress accelerated life tests are considered when the lifetime of a product under use condition
follows a finite mixture of distributions. The experiment is performed when each of the components in the mixture follows
a general class of distributions which includes, among others, the Weibull, compound Weibull, power function, Gompertz and
compound Gompertz distributions. It is assumed that the scale parameter of each component satisfies the inverse power low,
the progressive stress is directly proportional to time and the cumulative exposure model for the effect of changing stress
holds. Based on type-I censoring, the maximum likelihood estimates (MLEs) of the parameters under consideration are obtained.
A special attention is paid to a mixture of two Rayleigh components. Simulation results are carried out to study the precision
of the MLEs and to obtain confidence intervals for the parameters involved. 相似文献

Die Notwendigkeit zur wertorientierten Führung und Steuerung von Unternehmungen gewinnt durch die zunehmende Professionalisierung
der Kapitalmarktteilnehmer, die Basel-II-Richtlinien für Banken sowie die Neuregelung zum Goodwill Impairment weiter an Dynamik.
Innerhalb der Wertkonzepte nehmen Kapitalkosten als zentraler „value driver“ eine herausragende Bedeutung ein. Vor diesem
Hintergrund werden die unterschiedlichen Verfahren zur Ermittlung von Kapitalkosten, darunter auch das erst kürzlich vorgestellte
Market-derived Capital Pricing Model, diskutiert und mittels eines zu entwickelnden Kriterienrasters systematisch miteinander
verglichen. Schlie?lich entwickelt der Beitrag aus den Erkenntnissen des Verfahrensvergleichs sowie einer Expertenbefragung
praktische Anwendungsempfehlungen. 相似文献

We characterize the equilibrium of the all-pay auction with general convex cost of effort and sequential effort choices. We
consider a set of n players who are arbitrarily partitioned into a group of players who choose their efforts ‘early’ and a group of players who
choose ‘late’. Only the player with the lowest cost of effort has a positive payoff in any equilibrium. This payoff depends
on his own timing vis-a-vis the timing of others. We also show that the choice of timing can be endogenized, in which case
the strongest player typically chooses ‘late’, whereas all other players are indifferent with respect to their choice of timing.
In the most prominent equilibrium the player with the lowest cost of effort wins the auction at zero aggregate cost.

This empirical note extends the recent work by Holmes (2006) in examining the long-run relationship between private and public
savings in the U.S. over the post-World War II period. Standard Engle-Granger cointegration tests fail to reject the null
hypothesis of no cointegration; however, once allowance is made for an endogenous break in the cointegrating relationship,
the weak form of the Ricardian equivalence proposition is supported. 相似文献

The literature on US state government fiscal performance has examined the role of institutional factors such as budget rules
and divided government, but has largely ignored the impact of party alternation. This paper primarily focuses on whether party
alternation in the governor’s office affects fiscal performance. Our hypothesis is that frequent party changes create a political
environment that impacts fiscal performance. To further assess the impact of party alternation on fiscal performance, we consider
our primary hypothesis in conjunction with the degree of division that exists between the governor’s office and the legislature.
Using panel data from 37 states between 1971 and 2000 we test the hypothesis that frequent party alternation can be expected
to affect fiscal performance and find strong support for the hypothesis.
An earlier version of this paper was presented at the 2005 Public Choice Society Meetings. The authors would like to thank
the conference participants, William Shughart, Charles Register, Jocelyn Evans, John D. Jackson, Amihai Glazer, and two anonymous
referees for their comments. We would also like to thank Craig R. Stiller for his help in the collection of data. Any remaining

Scanner data for fast moving consumer goods typically amount to panels of time series where both N and T are large. To reduce the number of parameters and to shrink parameters towards plausible and interpretable values, Hierarchical Bayes models turn out to be useful. Such models contain in the second level a stochastic model to describe the parameters in the first level. 相似文献
