The magnification effect in standard international trade theory asserts that if the relative price of the labor-intensive commodity increases, the real wage will also increase, as will the wage/rental ratio. This result depends upon the assumption that both activities are nonjoint—each combining labor and capital to produce a single output, so that if activities are joint instead, the results are in jeopardy. It is shown that if the difference between the share of commodity one produced in the first activity and in the second activity exceeds the difference between the labor distributive shares in the first activity and the second, an increase in commodity 1's relative price raises the wage/rental ratio. The real wage unambiguously rises in this case if and only if the ratio of the commodity output shares in the two activities exceeds the ratio of labor shares. 相似文献

The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory
tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative
to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward
view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the
resulting implications for intertemporal decision-making experiments.

公司必须承担社会责任是我国新公司法的要求,在实践中如何理解这一责任,甚为重要,直接关系到公司的发展和新公司法的实施.立足于现阶段的社会实践,公司社会责任的基本内涵是要求公司在其经营活动中不得有损于社会和谐及社会发展并因此而承担相应的社会义务,这一义务以保障劳工权益、保护环境、珍惜资源为核心.这种对公司社会责任的理解极具现实意义.同时,探讨如何将新公司法这一倡导性规范的要求合理地付诸实践也是我们不可回避的问题. 相似文献

Summary. In this paper, we establish the most possilbe general formulation of the technology governing carbon-gas emission, giving
rise to global external diseconomies, and ty to explore into the strategic interactions,both domestic and international, when
an individual country decides on the environmental policies. Through the comparison among emission taxes, quotas, and standard
in the perfectly competitive private economies, we find that the first two policies are equivalent but they are different
in effects by virtue of what we may call the tax-exemption effect of emission standards. Such a difference in the policy effect
further affects the other country's welfare through the global externalities, amplified through whether the government can
precommit to either the emission tax or the emission standard.

已有的对城乡和谐发展问题的研究大多将注意力集中在城乡和谐发展的途径方面,却忽视了对城乡和谐衡量标准的研究.本文从公平与效率统一(均衡)的视角来解析城乡和谐的标准以及城乡和谐演进的机制,并构建了一个基于公平与效率均衡的城乡和谐发展模型.该模型揭示,城乡和谐是公平与效率均衡的函数,市场机制与政府制度的相互配合共同促进城乡和谐发展. 相似文献

金融租赁公司的利率风险及管理对策 总被引:2,自引:0,他引:2
金融租赁公司所面临的诸多利率风险中,成熟期错配风险是最为关键的,久期模型是其通用的衡量方法。金融租赁公司的久期缺口分析是利用久期管理利率风险的主要方法,但久期模型运用中也存在着诸如久期对称成本高、利率风险免疫动态性及凸性等问题。金融租赁公司面对利率上升的风险,应采取设立风险管理部门、做好基础资料积累与分析、加强利率走势预测及对金融衍生工具的研究等对策措施。 相似文献

Keynes, uncertainty and interest rates 总被引:1,自引:0,他引:1
Uncertainty plays an important role in The General Theory, particularlyin the theory of interest rates. Keynes did not provide a theoryof uncertainty, but he did make some enlightening remarks aboutthe direction he thought such a theory should take. I arguethat some modern innovations in the theory of probability allowus to build a theory which captures these Keynesian insights.If this is the right theory, however, uncertainty cannot carryits weight in Keynes's arguments. This does not mean that theconclusions of these arguments are necessarily mistaken; intheir best formulation they may succeed with merely an appealto risk. 相似文献

We study the distribution of basic scientific research across countries and time, and explain the process that resulted in
the United States becoming the undisputed leader in basic research. Our study is based on the records of scientific awards,
and on the data of global economic trends. We investigate the degree to which scale/threshold effects account for the number
of prizes won. We constructed a stylized model, predicting a non-linear relationship with lagged relative GDP as an important
explanatory variable of a country’s share of prizes. Our empirical research findings find support for these predictions and
the presence of a “winner-takes-all” effect.
