世界上很多国家通常都把货币需求作为货币政策的中介目标,稳定的货币需求对一国的货币政策甚至宏观经济政策的有效性有着重要的影响.通过实证研究发现,金融创新对我国货币需求的稳定有着不可忽视的重要影响,我国货币需求与实际产出等变量之间的稳定关系只有在考虑金融创新的影响时才能够成立. 相似文献

This paper proposes a spatial structural decomposition analysis to measure the effects of the changes in intra- and inter-country linkages on the embodied energy demand in the concerned country. For the empirical analysis, we have used the China- Japan inter-country input–output tables for 1985 and 1990, expressed in constant prices of 1990. The empirical results reveal that (1) at least for the period between 1985 and 1990, the effects of the non-competitive input structural changes in China on the primary energy requirements of Japan were negligible, and (2) the contribution of the Japanese final demand shifts on the total change in Chinese primary energy demand was 40 times larger than that of the Chinese final demand shifts on the primary energy requirements of Japan. The Japanese policy makers should concentrate on the energy impacts of the changes in the domestic production structure rather than the changes in the Chinese production structure. 相似文献

To study the optimal age-specific labor demand and human capital investment at the firm level we extend the standard dynamic labor demand model by introducing ‘age’ as a second dynamic variable and distinguish between two types of workers: ‘low skilled’ and ‘high skilled’. Applying an age-structured optimal control model we derive qualitative features of the optimal age-specific hiring and training effort. For the case of a linear revenue and production function we prove that firms do not anticipate changes in adjustment costs in their optimal decisions. This result no longer holds if a nonlinear revenue or production function is considered. 相似文献

Summary. I highlight the importance of the distributional aspects of moneys divisibility by comparing a search-theoretic model with random transfers of indivisible money balances, to one with deterministic transfers of partially divisible balances. Randomization allows price flexibility, as if money were fully divisible. Partial divisibility does not, but allows money redistributions. An example of the relevance of such extensive margin aspects of divisibility is provided.JEL Classification Numbers:

This paper develops a new technique for proving the existence and indeterminacy of monetary equilibria in money search models
with divisible money. Our technique is substantially simpler than standard constructive proofs in the literature.
This paper is based on the second half of Kamiya and Shimizu (2002). We are very grateful to the associate editor and an anonymous
referee of this journal for their very detailed suggestions and comments. This research is financially supported by Grant-in-Aid

Synopsis: The oft-cited analogies between ecological and economic systems are exploited to develop a many-species model of
population dynamics. In economies, markets are the fundamental institutions in which the interaction of demands and supplies
determine the quantities and prices of goods. However, economic markets are not appropriate for ecological communities, because
markets rely on voluntary exchange, whereas plants and animals engage in involuntary transfers of biomass. A properly defined
counterpart to markets based on biomass transfers permits a general equilibrium model of predator/prey and competitive interactions
in a many-species community. Functional response from optimal foraging and predation risk provide the demand and supply, respectively,
in the biomass transfers. Energy per unit time is scarce and predators and prey make optimum choices with respect to functional
response and risk avoidance based on required energy expenditures. The energy expenditures are similar to economic prices:
they determine foraging strategies and are beyond the control of the predators and prey, yet they are determined by the aggregate
choices of all predators and prey and by population densities. The energies acquired from foraging are used in a new way to
construct difference equations that determine the population dynamics.

我国特殊的股权结构决定了我国上市公司的主要代理问题是大股东与中小股东之间的代理冲突。大股东往往通过各种方式如资金占用等来对上市公司进行掠夺。在西方成熟的资本市场上,审计作为一种独立的外部监督机制能够在一定程度上抑制代理冲突。那么在我国新兴的市场中,审计能否起到有效的监督作用从而抑制大股东的“利益输送行为”呢?本文从需求和供给两个方面进行了研究。实证结果发现,从需求方面来说,大股东资金占用越严重的公司越没有动机聘请高质量的审计师;从供给方面来说,审计师在出具审计报告时会考虑大股东的资金占用,大股东资金占用越严重,越有可能被出具非标准的审计意见报告。实证结果表明我国目前还不存在高质量的审计需求,但审计师能对大股乐的资金占用作出反应,从而在一定程度上抑制大股东的行为。 相似文献
