诱致性制度变迁下的农民合作社发展路径研究

根据我国农村经济的发展现状,专门从诱致性制度变迁的视角深入分析合作社的产生机理及未来发展方向。在分析促使合作社产生和发展的诱致性变迁因素的基础上,以股份合作制为例提出诱致性制度变迁视角下我国农民合作社未来发展路径的制度安排。     

Economic natural selection in Bertrand and Cournot settings

We study economic natural selection in classical oligopoly settings. When underlying pure strategies consist of a finite number of prices, convex monotonic dynamics always converge under a weak condition to the smallest price in the support of the initial state that exceeds marginal cost. When underlying pure strategies consist of a finite number of quantities, monotonic dynamics always converge under a specific condition to a quantity equal or similar to classical Cournot equilibrium.     

Political Stock Markets and Unreliable Polls

A political stock market (PSM) clearly beat the polls in predicting the outcome of a Swedish referendum on whether or not Sweden should join the European Union. In fact, polls were unable to make such predictions since the number of undecided respondents always far exceeded the observed YES/NO margin. However, an obstacle to PSMs serving as a superior forecasting instrument is that they can be sensitive to price distortions - by interest groups that may wish to effectuate, and pay for, such distortions - or forecast competitions tied to PSM trade gains, the latter of which was tested here.     

Efficiency in coalition games with externalities

A natural extension of superadditivity is not sufficient to imply that the grand coalition is efficient when externalities are present. We provide a condition, analogous to convexity, that is sufficient for the grand coalition to be efficient and show that this also implies that the (appropriately defined) core is nonempty. Moreover, we propose a mechanism which implements the most efficient partition for all coalition formation games and characterizes the resulting payoff division.     

Constitutional coordination in unstable party systems: the Brazilian constitution of 1988

Constitutional assemblies are a common feature of many democratic transitions. However, the goal of coordinating constitutional choice would seem nearly impossible when assemblies are comprised of highly fragmented and volatile political parties. Building on Knight’s bargaining model, this article argues that the main challenge to coordination in unstable party systems is the procedural disequilibrium that results from incomplete information over breakdown payoffs. The likelihood of compromise in such circumstances is a function of the ideologies that frame constitutional choice and inform coalition-building. Thus, unstable party systems are not chaotic, although they may be deeply conflict-laden. These issues are illustrated empirically via the Brazilian Constitution of 1988, which demonstrates the possibilities for a stable constitutional order emerging from a fragmented and volatile party system.

论我国农民专业合作社的发展空间

在与农业生产者的交易中,合作社是一种比IOFS有利于节约交易费用的制度安排,通常出现在由于资产专用性等因素的影响从而交易成本较高的领域。另一方面,集体行动的困难增加了合作社内部的协调成本,保持凝聚力的努力也使合作社成为内部组织成本较高的治理结构,导致合作社内部组织成本继续上升的因素将限制合作社的发展空间。我国存在普遍的农民兼业现象、农业生产规模小、农户间异质性程度高,这些约束条件提高了组建合作社的协调成本,成为制约我国农民专业合作社发展的主要障碍。     

新农合制度本身及运行相关问题研究综述

文章对现有学者在新型农村合作医疗制度本身及运行相关问题研究整理发现:制度本身问题研究主要集中于定性分析、运行过程中定量研究模型重复率高、国外借鉴较少考虑我国的适用性。许多研究内容有待进一步的探索和加强,具体体现在五个方面:贫困地区外出打工者的医疗保障问题、城乡医疗保障的衔接问题、补偿水平及保障范围的研究、新旧合作医疗的比较问题研究、各环节监管独立性探究。
