We propose a new cost allocation rule for minimum cost spanning tree games. The new rule is a core selection and also satisfies cost monotonicity. We also give characterisation theorems for the new rule as well as the much-studied Bird allocation. We show that the principal difference between these two rules is in terms of their consistency properties. 相似文献

The comparison of true cost of living indices between demographically different households (relative equivalence scale) is argued to be sensitive to the way demographic characteristics enter demand analysis. In particular, parameters reflecting the cost of demographic characteristics at base prices, though themselves do not have welfare (equivalence scale) interpretation, can alter the benchmark from which demographically varying inflation effects are measured. The empirical analysis, based on a rank‐3 demand system applied to UK individual household data, shows that the inflation adjustment of child benefits can vary with the way demographic costs at base period prices are specified. 相似文献

This paper uses a two-country, flexible-price model with overlapping generations of infinitely lived households to study the role of net foreign asset dynamics in the propagation of productivity shocks. Absence of Ricardian equivalence ensures existence of a unique steady-state level of net foreign assets, to which the economy returns following temporary shocks. Model dynamics are significantly different from those of a setup in which terms of trade movements perform all the international adjustment and net foreign assets do not move. The difference relative to a complete markets economy in which net foreign asset movements play no role in shock transmission is smaller. It is amplified if the substitutability across goods rises and if shocks are permanent. 相似文献

This paper is devoted to studying optimal designs for estimating an extremal point of a multivariate quadratic regression model in the unit hyperball. The problem of estimating an extremal point is reduced to that of estimating certain parameters of a corresponding nonlinear (in parameters) regression model. For this reduced problem truncated locally D-optimal designs are found in an explicit form. The result is a generalization of the results of Fedorov and Müller (1997) for onedimensional quadratic regression function in the unit segment.

Flexible firms compete by means of wages in the Assignment market while rigid firms have no flexibility over terms of appointment in the Marriage market. Workers trade with both kinds of firms in the hybrid market.Examples show that standard results that characterize the core of the Marriage market (respectively, Assignment market) are not robust to the entrance of flexible (respectively, rigid) firms to this market. A new algebraic structure provides a different characterization for the core of the hybrid model and reflects a sort of robustness to the exit of rigid (respectively, flexible) firms from this market. Meaningful comparative static results are derived. 相似文献

The evidence presented in the paper rejects the twin deficit hypothesis for the Austrian current account balance during the
last two decades. The results are based on an estimate of a vector error correction model including quarterly data for the
current account balance and potentially relevant variables driving its dynamics. We compute the variance decomposition of
the current account's forecast error and its generalized impulse responses to shocks in the innovations of the system. The
results in favor of intertemporal expenditure reallocation cannot be reproduced within a second analysis including the current
account and a measure of net output, however. The estimated implicit current account balance, interpreted as the discounted
expected change in future net output, does not follow the actual behaviour of the current account.

Complementary slackness of a pair of dual linear programming problems implies the remark of Sotomayor (2003) that assignment games have singleton cores only when multiple optimal matchings exist.The author thanks Marilda Sotomayor, William Thomson, and an anonymous referee for their helpful comments. This paper was finished when the author was visiting University of Rochester. JEL Classification Numbers: C71, C78, D58 相似文献

目前,学界对于核心能力和知识管理两者关系的研究,大多数仅仅是逻辑推导,而缺少理论体系的构建和严格的数理证明。本文从核心能力要素一层次模型构建着手,通过对知识管理中组织行为、个人行为与核心能力的相关作用机理进行研究,建立了核心能力一知识管理价值创造机理模型,并从组织行为和个人行为两个方面对该模型进行了数理证明。 相似文献

在市场经济体制下,多元化经营成为大企业实现可持续成长的共同战略,但企业成功实施多元化经营需具备资金、技术和管理等方面的实力.而近年来我国一些企业核心竞争力的下降与盲目地多样化战略有很大关系,所以回归主营业务和建立核心竞争力是企业应该考虑的首要战略. 相似文献
