The number of pure Nash equilibria in a random game with nondecreasing best responses

We randomly draw a game from a distribution on the set of two-player games with a given size. We compute the distribution and the expectation of the number of pure-strategy Nash equilibria of the game conditional on the game having nondecreasing best-response functions. The conditional expected number of pure-strategy Nash equilibria becomes much larger than the unconditional expected number as the size of the game grows.     

The concept of choice: why and how innovative behaviour is not just stochastic

The goal of this paper is to highlight the importance of the concept of choice. To do so, a synopsis of the most important contributions to this topic—featuring an eclectic set of scholars across disciplines—is provided. As central to the argument, John von Neumann’s contributions, game theory and simulation techniques on von Neumann machines, are identified. Innovation (economic and theoretic) as the driving force behind human evolution seems to head for a new scientific paradigm based on von Neumann’s ideas.

Switches and fake switches in methods of production

It has long been recognised that Sraffa's analysis of the choiceof methods in joint production cannot be sustained, so thatpost-Sraffian economists have abandoned it. The paper returnsto Sraffa's own approach and identifies two characteristic elements:methodologically, it is of a ‘dynamic’ nature (itconsiders a potential move of the rate of profits) and, analytically,the switch-points are the common intersection of several wage–profitcurves. An internal critique consists in showing the existenceof fake switches, which are at the intersection of two wage–profitcurves but, unexpectedly, are not switch-points.

对中国国际贸易与FDI相互关系的重新检验

This paper studies the long-term relationship between FDI and imports and exports through evidence from China by using cointegration technology, and the Granger causality test shows that FDI had an obvious effect on imports and exports activities of foreign firms, and in the meantime, the imports and exports of foreign firms greatly promoted FDI. However, there is not a stable equilibrium between FDI and international trade in the long run for all firms in China. This paper provides some explanations for the possible reasons that cause the above difference in estimation results from the perspectives of both location and industry factors.      

Existence and Welfare Properties of Equilibrium in an Exchange Economy with Multiple Divisible and Indivisible Commodities and Linear Production Technologies

In this paper we consider a class of economies with a finite number of divisible commodities, linear production technologies, and indivisible goods and a finite number of agents. This class contains several well-known economies with indivisible goods and money as special cases. It is shown that if the utility functions are continuous on the divisible commodities and are weakly monotonic both on one of the divisible commodities and on all the indivisible commodities, if each agent initially owns a sufficient amount of one of the divisible commodities, and if a “no production without input”-like assumption on the production sector holds, then there exists a competitive equilibrium for any economy in this class. The usual convexity assumption is not needed here. Furthermore, by imposing strong monotonicity on one of the divisible commodities we show that any competitive equilibrium is in the core of the economy and therefore the first theorem of welfare also holds. We further obtain a second welfare theorem stating that under some conditions a Pareto efficient allocation can be sustained by a competitive equilibrium allocation for some well-chosen redistribution of the total initial endowments.

管子轻重理论的均衡思想

<管子>后16篇,也称轻重篇,着重阐述了轻重理论,是中国古代特有的一种经济管理思想.前人学者大多从供求规律与货币数量论等角度对商品之间的轻重规律进行阐释.文章则重点阐述了轻重规律所蕴含的均衡思想,并且在阐述管子轻重理论中蕴含的局部均衡、动态均衡、一般均衡思想后,借用现代经济学的分析工具,试图重建管子轻重规律的均衡分析.西方经济学直到1769年以后才在经济学中引入均衡的概念,此研究将进一步丰富中国经济思想的研究.     

The Keynesian Features of Graziani's Monetary Theory of Production and Some Unresolved Issues

Abstract

The aim of this article is twofold. First, it seeks to verify the elements of affinity between Graziani's approach to the Monetary Theory of Production and Keynes’ Treatise on Money and his General Theory. It is shown that two important theoretical elements, from the Treatise on Money, enter Graziani's basic schema, namely the view of endogenous money supply and the distribution process. At the same time, uncertainty and aggregate demand—conceived as a crucial variable in the General Theory—can play a significant role in the basic schema of the Monetary Theory of Production. Second, the article sets out a critical reconstruction of Graziani's basic schema emphasising the existence of ‘open issues’– such as bank behaviour and the ‘paradox of profits’—relating to internal and external inconsistencies.     

基于盖斯克模型与模糊数的综合模型在风险投资项目中的应用

风险投资项目具有高不确定性,因此将风险投资项目复合实物期权方法中的期望现金流现值和投资成本均假定为确定值是不现实的。因此本文运用了复合实物期权(Geske模型)与模糊数的综合模型。该综合模型较好地解决了风险投资项目中的期望现金流现值和投资成本不为确定值的情况,并结合实例证明了其有效性。     

独立董事比例、产权性质与长期债务融资契约

独立董事比例越高则长期债务融资比重越大,这一现象只在民营上市公司样本中有稳定表现,原因在于独立董事比例越高,监督能力越强,民营公司独立董事承担的监管风险相对更高,监督动力更强。监管当局应该适当提高上市公司独立董事比例,严格独立董事责任机制,以进一步改进独立董事制度效率。     

The Exchange Rate and Inflation in Argentina: A Classical Critique of Orthodox and Heterodox Policy Prescriptions

In this paper we present an alternative framework to neoclassical theory of international trade and exchange rate determination. Our model, inspired in the classical tradition, provides support for the assertion that an exchange rate policy aiming to improve national competitiveness and to bring about a sustained trade surplus is a viable option. In fact, the success of this strategy does not depend on the effectiveness of monetary sterilization —as many argentinean heterodox authors claim— but on the ability to overcome the boundaries imposed by the evolution of the domestic wage rate and the potential emergence of competitive devaluations. In the particular case of Argentina, the introduction of export taxes on land-intensive commodities, in which the economy has absolute advantages, brings an additional policy tool that can make both the exchange rate target and the workers claims consistent.     

石油企业与地方区域经济发展的均衡性研究

我国石油企业与地方经济发展水平和增长速度存在明显的不均衡,石油企业相对地方经济超前发展有其先天优势条件和客观因素,区域经济非均衡发展的相关理论为油地区域经济发展的均衡性研究提供了理论依据。从长期看,只有从规范油地区域分工、互补功能、互惠共赢的全方位视角认知由石油企业拉动地方经济组合联动的模式切换,驾驭产业和城市的协调发展,突出城市发展的整体性和综合性,才能实现油地区域经济的协调持续健康发展。     

劳动价值论与非劳动生产要素按贡献参与分配制度

非劳动生产要素按贡献参与分配制度的理论依据,首先是非劳动生产要素在商品使用价值和价值形成中的贡献,这是非劳动生产要素按贡献参与分配的价值基础和尺度;在此基础上形成的生产资料所有制及其产权关系和商品经济原则,是非劳动生产要素的贡献在现实经济关系和法律上的体现,是非劳动生产要素按贡献参与分配的直接原因.马克思劳动价值论对这两个方面都有科学的阐述.     

The Capital Idea and the Scope of Economics

This paper traces the idea of Capital from Adam Smith to modern times and shows how different conceptions of Capital give rise to different approaches to economics and the range of problems that can be investigated. A structural, as opposed to a stock, approach to Capital is shown to be more conducive to a studies of business institutions and practices, and to rules, institutions and standards in a changing world.     

劳动价值论与生产要素参与价值分配问题研究

马克思劳动价值论中只承认直接从事物质生产的活劳动才创造价值,而作为社会劳动凝结物的劳动手段和劳动对象是物化劳动,只能转移价值,同时也承认非劳动生产要素在价值创造中的作用.笔者梳理了理论界对传统劳动价值一元论的新认识,认为马克思劳动价值论与生产要素参与价值分配并不矛盾.     

Stackelberg equilibrium with many leaders and followers. The case of zero fixed costs

I study a version of the Stackelberg game with many identical firms in which leaders and followers use a continuous cost function with no fixed cost. Using lattice theoretical methods I provide a set of conditions that guarantee that the game has an equilibrium in pure strategies. With convex costs the model shows the same properties as a quasi-competitive Cournot model. The same happens with concave costs, but only when the number of followers is small. When this number is large the leaders preempt entry. I study the comparative statics and the limit behavior of the equilibrium and I show how the main determinants of market structure interact. More competition between the leaders always displaces the followers. Instead, how a stronger threat of entry affects the equilibrium depends on the technology. With strictly convex costs it is the followers that eventually displace the leaders.     

The Stories That Economists Tell: Mainstream,Hyman Minsky,and Institutional Views of Consumer Behavior

The financial crisis of 2008 provided an informal test of mainstream and institutional views of consumer behavior. The test posed by the financial crisis assumes the form of a “story.” A successful story provides a reasonably coherent explanation of events, confirming our beliefs and justifying our policies. First, the article examines the failure of mainstream economics to present a coherent story of consumer behavior. Ignoring the relevance of assumptions, as Milton Friedman advocated, leads economists to hypostasize the model, filtering information central to the crisis. Second, Minsky’s discussion of consumer behavior and its effect on cash inflows to businesses represents an institutional explanation regarding why John Maynard Keynes’s long-run vision did not occur. The third section expands on some of the themes addressed by Minsky, which are found among the contributions of institutional economists, focusing on efforts to mold institutions to increase cash inflows to corporations and protect those inflows.     

马克思相对过剩人口理论视角的我国当前失业问题探析

马克思的相对过剩人口理论是伴随着资本主义社会资本积累和资本有机构成提高而产生的,对研究我国当前的失业问题具有重要的理论指导意义。劳动力总供给大于总需求、产业结构调整、科学技术进步与广泛应用、劳动力素质与市场需求脱节等是我国当前失业问题产生的原因。其解决对策主要有,保持经济稳定增长,增加社会财富;发挥人口优势,大力发展第三产业;加快科技创新,推进社会分工;实施扩大就业战略,努力实现充分就业;改革教育制度,提高劳动者就业能力等。     

国外农村劳动力迁移理论的演变与发展

根据对农村劳动力迁移决策的不同解释,把国外有关劳动力迁移的主要文献分为三类:传统的劳动力迁移理论(包括刘易斯模型、拉尼斯-费景汉模型、托达罗模型)、人力资本劳动力迁移理论和新劳动力迁移理论.目前国内研究劳动力迁移的文献主要以传统劳动力迁移理论和人力资本劳动力迁移理论为研究基础,而对新劳动力迁移理论的借鉴和应用还比较罕见,因此值得我们学习和研究.
