Monotone Matching in Perfect and Imperfect Worlds 总被引:1,自引:1,他引:0
We study frictionless matching in large economies with and without market imperfections, providing sufficient conditions for monotone matching that are weaker than those previously known. Necessary conditions, which depend on a key analytical object we call the surplus function , are also offered. Changes in the surplus yield valuable information about the comparative statics of matching patterns across environments. We apply our framework to some examples adapted from the literature, accounting for and extending several comparative–static and welfare results. We also explore the dependence of the matching pattern on the type distribution. 相似文献

This position paper outlines how recent 'irreductionist' research and theorizing can enrich the insights provided by Marx and by commentators on Marx such as Schumpeter and Habermas into the relationship between science, technology and social change. The paper begins with a review of Marx's discussion of commodities and their relation to the forces and relations of production, Schumpeter's discussion of the processes of invention and innovation and Habermas' discussion of techne (instrumental knowledge), praxis (moral understanding) and their relation to processes of emancipation. The paper then suggests how understanding the relationship between invention, innovation, and emancipation is deepened and reframed by irreductionist approaches to the study of 'research worlds'. An irreductionist perspective on commodities and commodification is briefly outlined. 相似文献

一、重要领域的社会创新1.可持续发展和消费领域的社会创新我国已提出建设节约型社会、提倡绿色消费以及生态生产模式等发展思路,这些对我国经济社会的协调发展将产生深远影响。在可持续发展方面,主要任务是保证经济和社会的协调发展,同时注重环境保护,提高资源的使用效率。与会代表首先讨论了可持续消费的重要性。有代表认为,消费的可持续性在实现可持续发展中具有非常重要的作用。过度消费不仅会造成大量的浪费,产生能源危机,而且还会形成社会中各利益集团的对立。可持续消费则有利于减缓能源浪费和资源危机,对社会风气的好转也会起到促进… 相似文献

现在,各地求发展的劲头很大,注意取人之长补己之短蔚然成风。今天参观考察这里,明天学习借鉴那里,欲与发达地区对接、互动。回来后按捺不住激动的心情,将人家的东西大胆拿来,指望产生立竿见影的效果。起初蛮奏效,日久才感到许多经验在本地推行真如“蜀道难”。看来:别人的东西未必全都适合自己。温 相似文献

湖北是一个油菜种植大省,各地区农户油菜供给行为却存在着差异,他们受到农产品商品率、兼业程度、资产专用性程度、土地利用方式、农产品市场结构等因素的影响。当价格出现波动时,各地区农户的供给反应更不相同。因此,分析了解这些差异有助于我们更有利的促进油菜生产。 相似文献

本文依据现代综合进化论的观点分析认为,由于选择因素的不同,在自然条件下、人工条件下以及污染条件下,生物进化的方向、性质及其稳定性也各不相同。在自然条件下,生物朝着更加适应环境的方向进化;长期的人工选择可能导致选择的极限,甚至物种的崩溃;而环境污染对生物进化的影响具有全球性,它可能会降低整个生物界进化的潜力,危及地球上所有生物的生存与安全。 相似文献

Adjustments in Different Government Systems 总被引:2,自引:0,他引:2
Enrico Spolaore 《Economics & Politics》2004,16(2):117-146
This paper develops a model in which agents have a conflict of interest over what instrument to use for policy adjustment in response to shocks. Three different government systems are analyzed: cabinet systems, in which one decision-maker has full control over adjustment policies; consensus systems, in which adjustment policies must be agreed upon by all agents; and checks-and-balances systems, in which one agent decides what instrument should be used for adjustment, but the remaining agents may veto its use. All three systems may lead to inefficient policies. The cabinet system adjusts too often. The other systems may fail to adjust when adjustment is optimal. The relative performance of the three systems depends on the degree of political fragmentation and the size distribution of shocks. 相似文献

Comparing Different Central Bank Targets 总被引:1,自引:0,他引:1
In this paper we analyze different target regimes for a central bank. First, we determine the main macroeconomic variables under inflationtargeting and nominal income targeting in the context of a Mundell–Flemmingtwo country model. We then investigate under which conditions onetarget regime is superior to another if supply or demand shocks occur.The main result of this paper is that there exists a unique boundary for theweight on employment in the objective function of the centralbank. If the actual weight is smaller than this bound, inflation targetingis superior to nominal income targeting. For a weight larger than thisbound, nominal income targeting causes a smaller loss. For the two extremecases of the weight, namely zero or infinity one target regime coincideswith the loss-minimizing solution: inflation targeting for a weight of zeroand nominal income targeting for a weight of infinity. 相似文献

基于不同经济区域与行业的并购效率比较 总被引:3,自引:1,他引:2
上市公司所处的经济区域及行业会显著影响并购效率,目前这方面的研究还非常不够。本文利用改进的DEA(数据包络分析)模型进行分析,实证结果发现:总体上看,随着资本市场制度的不断完善及市场监管的强化,自2001年以来,并购市场的效率在稳步提高,2005年以后更为显著;并购集中于信息产业、生物医药、房地产、社会服务、能源电力、商业类等行业,成为目前并购市场的热点领域,且不同行业的并购效率存在显著差异;不同经济区域的上市公司并购效率存在明显区域差别。究其原因,主要在于各经济区域所拥有的自然条件及资源禀赋状况不同、市场化程度及政府干预程度不同所致。 相似文献

农村土地制度的多样性选择 总被引:4,自引:0,他引:4
本文运用“斯密-科斯”模型论证了农村土地制度选择在于专业化和分工及由此网络效应而产生的交易成本增加的两难决策,不同的农产品市场、土地市场、劳动力市场的交易效率的变化,形成不同的分工淡化路径,诱致不同的农村土地制度,由此解释了多样化的农村土地制度存在的原因及其选择。 相似文献

不同学派利率理论问题的分歧,根源于其所依据的货币理论的不同。“古典”学派的实物利率理论源于其“两分法”货币理论;凯恩斯的纯货币利率理论源于其缺乏微观基础的货币经济理论;马克思以其科学的货币理论为依据,给予其资本利率理论以深刻的内涵。 相似文献
