The purpose of this paper is to provide an existence result of equilibria for economies with a measure space of agents, a non-trivial production sector and an infinite dimensional commodity space. The commodity space is modeled by an ordered separable Banach space whose positive cone has a non-empty interior. The discretization approach proposed in this paper, allows us to extend the existence results in Khan and Yannelis [Equilibrium in markets with a continuum of agents and commodities. In: Khan, M.A., Yannelis, N.C. (Eds.), Equilibrium Theory in Infinite Dimensional Spaces. Springer, Berlin, 1991] and Podczeck [Economic Theory 9 (1997) 585] to economies with a non-trivial production sector and with possibly non-ordered but convex preferences as well as partially ordered (possibly incomplete) but non-convex preferences. 相似文献

We consider a model of an oligopolistic market with heterogeneous firms and products where neither the cost nor the demand functions are common knowledge. Instead, each firm only has some vague ideas about the price strategies adopted by its competitors which is modelled by a fuzzy set. In analogy to the notion of an "equilibrium of actions and beliefs" we define and characterize a generalized Nash-equilibrium and show its existence under general conditions. Furthermore, the impact of the fuzzy information on the equilibrium outcome is analyzed by means of a comparative static analysis within a particular model framework.Received: 28 May 2002, Accepted: 25 December 2002, JEL Classification:

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

Olga Shvetsova 《Constitutional Political Economy》2005,16(2):125-141
William Riker ((1964) Federalism: Origin, Operation, Significance. Boston: Little Brown) stressed the problem of the contested nature of federal institutions and argued that federations existed
amidst the ongoing challenge to their rules, that federal institutions were being continuously endogenously produced in the
interaction of political parties rather than serving as self-enforceable constraints on the political process. As parties
changed, so did federalism, and eventually the balance was bound to shift to either one or the other extreme as far as the
degree of centralization was concerned. An alternative approach to essentially the same problem of federal instability was
to conceptualize the underlying game differently, as a game of coordination, so that institutions would be accepted as constraints
and would therefore be self-enforceable because they allow the players to avoid the chaos and successfully converge to an
outcome with payoffs exceeding their reservation values (Hardin, 1989, Ordeshook, 1992). The third proposed solution, consociationalism,
emphasizes the elite effort to overcome the conflictual nature of the institutional choice (Lijphart, 1977). Here, as in the
coordination argument, the hope is that one could create incentives for politicians to view the existing rules as advantageous
and to avoid redistribution by means of the institutional revision. Yet, just like the coordination argument, it is based
on an implicit assumption that politicians are more easily motivated to act “cooperatively” than are their constituencies.
The missing step in the literature is the mechanism by which this more or less “cooperative” behavior of elected politicians
could be sustainable in the environment of popular accountability. An essential component in building the theory of institutional
design is to show the possibility in a democracy of elected politicians cooperating on institutional matters even when each
of their constituencies would prefer to adjust the constitutional terms to its own advantage. Elite “cooperativeness” must
be sustainable even in the presence of outside challengers promising to stay closer to the constituent preferences. Here,
I present a model of mass-elite equilibrium of constitutional legitimacy, which demonstrates the possibility to motivate the
incumbents to sustain the institutional stability while at the same time protecting them from electoral defeat. I also discuss
the difficulties and limitations that such a solution faces, in particular, in plural societies.

In working on this paper, I have benefited from the discussions with Mikhail Filippov, Peter Ordeshook, Charles Kromkowski,
Carol Mershon, and from the comments of the participants of the conference on ‘‘Micro-Foundations of Federal Institutional
Stability’’ at the MicroIncentives Research Center at Duke University, Durham, NC, April 30–May 1, 2004, and of the Lansing
Lee proseminar at the University of Virginia. The responsibility for the many remaining flaws is solely mine. 相似文献

Outsourcing, Imports and Labour Demand 总被引:7,自引:0,他引:7
This paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in German manufacturing sectors. We derive and estimate a factor demand system based on the generalised Box–Cox cost function nesting both the normalised quadratic and the translog functional form. We find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non–labour inputs. Similarly, the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution.

Summary. We prove existence of a competitive equilibrium in a version of a Ramsey (one sector) model in which agents are heterogeneous
and gross investment is constrained to be non negative. We do so by converting the infinite-dimensional fixed point problem
stated in terms of prices and commodities into a finite-dimensional Negishi problem involving individual weights in a social
value function. This method allows us to obtain detailed results concerning the properties of competitive equilibria. Because
of the simplicity of the techniques utilized our approach is amenable to be adapted by practitioners in analogous problems
often studied in macroeconomics.

基于演化博弈论的知识联盟动态复杂性分析 总被引:7,自引:0,他引:7
知识联盟是企业间为共同创造知识和进行知识共享而建立的联盟。本文从演化博弈论的角度,探讨了进行知识联盟的企业交互活动的复杂性可能对异质知识流的扩散和知识联盟稳定性造成多重可能结果。分析表明:一个企业实施知识流的更新(如建立知识联盟)和顺利扩散,取决于不同因素的作用,并表现出不同的复杂演化结果。对于已建立知识联盟的企业来说。这些不同的结果会对知识联盟的稳定性产生影响。如果企业最终都达到主动变流知识的策略选择状态,则异质知识得以在企业间扩散,从而强化企业间的知识联盟,但如果企业最终没有达到这一状态,则企业知识联盟的稳定性将被削弱。 相似文献

This paper investigates the impact of divergent consumer confidence on option prices. To model this, we assume that consumers
disagree on the expected growth rate of aggregate consumption. With other conditions unchanged in the discrete-time Black–Scholes
option-pricing model, we show that the representative consumer will have declining relative risk aversion instead of the assumed
constant relative risk aversion. In this case all options will be underpriced by the Black–Scholes model under the assumption
of bivariate lognormality.

基于中介效应模型和2007~2016年中国省际面板数据,构建异质性环境规制、技术创新与工业绿色化的作用机理理论分析框架,并通过构建异质性环境规制指标体系和工业绿色化指标体系将异质性环境规制与技术创新驱动工业绿色化的作用机理进行实证检验。研究发现:行政型环境规制对工业绿色化起抑制作用,不存在技术创新中介效应;市场型环境规制对工业绿色化的影响存在部分中介效应,可通过技术创新"挤出效应"抑制工业绿色化;公众型环境规制与工业绿色化关系只有中介效应,且公众型环境规制通过技术创新"激励效应"促进工业绿色化;异质性环境规制驱动工业绿色化的技术创新中介效应的研究结论经稳健性检验依然不变。研究认为:在推进异质性环境规制驱动工业绿色化过程中,应充分利用公众型环境规制驱动技术创新"激励效应",同时应有效规避市场型环境规制驱动技术创新"挤出效应"。 相似文献
