This paper deals with the problem of implementing the Walras correspondence via Nash equilibria, in exchange economies with infinitely many commodities and finitely many households with possibly non-ordered
preferences. We explicitly construct a feasible mechanism enjoying some features, which have natural economic meanings. Under
a fairly weak boundary condition, this game fully implements the Walras equilibria. If this condition is not fulfilled, our
mechanism nevertheless implements the constrained Walras equilibria.

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

Probability theory in fuzzy sample spaces 总被引:2,自引:0,他引:2
This paper tries to develop a neat and comprehensive probability theory for sample spaces where the events are fuzzy subsets of The investigations are focussed on the discussion how to equip those sample spaces with suitable -algebras and metrics. In the end we can point out a unified concept of random elements in the sample spaces under consideration which is linked with compatible metrics to express random errors. The result is supported by presenting a strong law of large numbers, a central limit theorem and a Glivenko-Cantelli theorem for these kinds of random elements, formulated simultaneously w.r.t. the selected metrics. As a by-product the line of reasoning, which is followed within the paper, enables us to generalize as well as to bring together already known results and concepts from literature.Acknowledgement. The author would like to thank the participants of the 23rd Linz Seminar on Fuzzy Set Theory for the intensive discussion of the paper. Especially he is indebted to Professors Diamond and Höhle whose remarks have helped to get deeper insights into the subject. Additionally, the author is grateful to one anonymous referee for careful reading and valuable proposals which have led to an improvement of the first draft.This paper was presented at the 23rd Linz Seminar on Fuzzy Set Theory, Linz, Austria, February 5–9, 2002. 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

A comparison is given of (ordinal) measures of trust in government institutions that were collected with the aim of facilitating
comparisons between different modes and contexts of data collection. Statistical analyses reveal that the mode effect could
amount upto a 10% change of item nonresponse and a 9% change of the level of trust, whereas the context effect could lead
upto a 19% change of the bivariate associations of trust. The observed changes of both measures of central tendency and of
associations affect conclusions of social scientific research in isolated studies, which implies that comparative studies
are seriously hampered by bias related to mode and context, two sources of obscurity adding to the two other threats which
are differences of sample source and differences of question phrasing. 相似文献
