This article highlights recent
improvements and plans for further
improvements to each of BEA’s major
regional economic accounts programs.
The improvements focus on
the acceleration of release of the estimates
and on the preparation of new
and extended estimates. There also is
a brief discussion on BEA’s research
effort to improve the regional
accounts.JEL Classification E010 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.
We thank Dan Kovenock and Luis C. Corchón for discussion and helpful comments. The usual caveat applies. Wolfgang Leininger
likes to express his gratitude to Wissenschaftszentrum Berlin (WZB) for its generous hospitality and financial support. 相似文献

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
