This paper examines the effects of government deficits, public investment, and public capital on welfare in the transition to an aging Japan by applying a simulated general equilibrium growth model. One of the main results of this paper is that targeting only high economic growth would mislead us as to economic policies, and that a policy to reduce future government deficits is most preferable for almost all generations, even though a cut in future deficits must be followed by a decrease in public investment, thus a decrease in public capital in the future.

Do we need an overlapping generations model for the economics of global warming? To answer this question, an infinitely-lived agent (ILA) approach and an overlapping generations (OLG) model are contrasted. ILA and OLG can be viewed as polar representations of intergenerational altruism. With ILA an immortal agent acts through his investment/savings decisions as trustee on the behalf of the future generations. With OLG, agents need not behave altruistic. They simply save during working years and dissave completely during retirement. Nevertheless, ILA and OLG must not differ in their implication for greenhouse policy. Greenhouse gas abatement is a straightforward alternative to physical capital formation and, even without altruism, each age cohort has an incentive to provide current abatement in order to reduce future damages attributable to climate change. Indeed, under reasonable assumptions and parameter values, our simulations reveal such an invariance result. Provided carbon taxes are the only policy tool and tax revenues are recycled through socially mandated rules, projections of economic growth, climate change and energy consumption are only insignificantly affected by the choice of approach. 相似文献

外部采购与加工贸易是近年来出现的新贸易现象,对中国来说,低廉的劳动力成本是取得加工贸易比较优势的主要原因,加工贸易发展进程中出口主体的分化是中国从城乡二元劳动力市场向城市二元劳动力市场转变的结果,要继续保持加工贸易比较优势,就应该增强劳动力市场的流动性,实现劳动力市场的统一。 相似文献

分部信息的披露主体主要是上市公司.公司出于竞争投资者有限的资金等目的有自愿披露分部信息的动因.由于分部信息披露存在成本,在没有管制的情况下,企业出于自身利益最大化考虑,将通过对收益和成本的权衡来决定分部信息披露.由于分部信息披露的外部性、分部信息分布的不对称性等,不能完全依赖于自愿披露,必须对分部信息披露进行适度的管制,强制公司披露分部信息. 相似文献

A small but growing body of literature uses overlapping generations (OLG) models to study environmental policy for long-lived problems such as climate change. An OLG model, unlike the infinitely lived representative agent model, dis- tinguishes between impatience with respect to one's own future utility, and attitudes toward successors' utility. I discuss the problem of time inconsistency, the role of Markov perfection, and show that a class of OLG models can be studied using me- thods developed to analyze models of non-constant discounting. An example illu- strates the techniques and determines the conditions under which, in equilibrium, there is under-investment or over-investment in natural capital. 相似文献

ABSTRACTClear and well-defined patent rights can incentivize innovation by granting monopoly rights to the inventor for a limited period of time in exchange for public disclosure of the invention. However, with cumulative innovation, when a product draws from intellectual property held across multiple firms (including fragmented intellectual property or patent thickets), contracting failures may lead to suboptimal economic outcomes. However, an alternative theory, developed by a variety of scholars, contends that patent thickets have a more ambiguous effect. Researchers have developed several measures to gauge the extent and impact of cumulative innovation and the various channels of patent thickets. This paper contends that mis-measurement may contribute to the incoherence and overall lack of consensus within the patent thickets literature. Specifically, the literature is missing a precise measure of vertically overlapping claims. We propose a new measure of vertically overlapping claims that incorporates invention similarity to more precisely identify inventive overlap. The measure defined in this paper will enable more accurate measurement, and allow for novel economic research on cumulative innovation, fragmentation in intellectual property, and patent thickets within and across all patent jurisdictions. 相似文献

The paper discusses the process for the endorsement of an IFRS in the European Union with regard to its compliance with teleological principles and with regard to the true and fair view. It begins with an exposition of the teleological principle under Roman law and its relationship to the true and fair view override, as known in the UK and in the EU. We then discuss firstly the telos-based criteria against which a new Standard is appraised during the endorsement process, and secondly the application of the true and fair view principle to the issue of which criteria an EU-endorsed IFRS should be appraised against as regards its application, using IFRS 3 as a specific illustration. The teleological principle is a crucial element in our conclusions. We show that this principle can be used, and in the EU is being used, to bypass democratic processes. The issues raised by this paper concern the operation of regulations designed to be, at least theoretically, context-neutral, within a specific legal and operational framework, that is, the European Union. But similar issues are likely to require consideration in other geographical areas, outside the European context. 相似文献
