Jean Tirole,Nobel Prize Winner

The Royal Swedish Academy of Sciences awarded the Nobel Prize in Economic Sciences for 2014 to Jean Tirole, Toulouse School of Economics (TSE), Toulouse, France ‘for his analysis of market power and regulation’. What commonly characterizes Jean Tirole's work is a combination of rigorous scientific analysis of markets and provision of useful scientific insights and policy guidance for regulation and competition policy in such markets. This paper focuses on two of Tirole's papers, both co-written with Jean-Charles Rochet, which probably best exemplify his policy-oriented research. It summarizes and then explains how the theory that these papers develop led to the implementation of a new policy regulating the payment card industry in the European Union.     

Cost-sharing in directed networks: Experimental study of equilibrium choice and system dynamics

This study reports the results of an experiment on directed networks with positive externalities induced by cost-sharing. Subjects participated in a network game in which they had to choose between private and public transportations. If a player chose public transportation, then she shared the travel cost equally with other players making the same choice, whereas if she chose private transportation, then her travel cost was fixed. Travel costs on the private route were manipulated across the two experimental conditions. In one condition, these costs were homogeneous among players; in the other condition, they were heterogeneous among players and only privately known. We found that half (none) of the player groups in the homogeneous (heterogeneous) condition converged toward the efficient equilibrium. Examination of the system dynamics shows that convergence toward efficiency was facilitated by: (1) the existence of an intermediate equilibrium choice; and (2) strategic teaching by which a farsighted player chooses strategies with poor short-term payoff in order to shift group decisions to the efficient equilibrium and thereby increase her own long-term benefit.     

The effects of public spending externalities

We conduct a positive analysis on the effects of ‘externalities’ produced by government spending. To this effect, we estimate, using U.S. data, an RBC model with two salient features. First, we allow government consumption to directly affect the marginal utility of consumption. Second, we allow public capital to shift the productivity of private factors. We provide an identification analysis that supports the strategy adopted for estimating the parameters governing these two channels. On one hand, private and government consumption are robustly estimated to be substitute goods. Because of substitutability, labor supply reacts little to a government consumption shock, so the estimated output multiplier is much lower than in models with separabilities. On the other hand, our results point towards public investment being ‘unproductive’.     

上海市交通拥堵成本测算及对策研究

依据美国德克萨斯运输学院交通拥挤外部成本的经典测算模型，将交通运输拥挤成本分为时间延误成本、额外燃油消耗成本、环境污染物排放成本和噪音成本三个方面，对于2015年上海市工作日高峰期交通拥挤的外部成本进行了详细的测算。结果表明，交通拥堵的外部成本约占当年上海市GDP的0.63%。最后，对于交通拥堵成本较高的现状提出了包括对上海市部分高度拥堵路段或区域收取拥堵费、大力发展上海市公共交通和发展交通快慢型出行方式共存在内的相关政策和建议。     

Relevance,responsibility, critical performativity,testimony and positive marketing: contributing to marketing theory,thought and practice

In this commentary, I chart recent changes at the Journal of Marketing Management (JMM). These include the introduction of a senior editorial board, a revised main editorial board and a modified team of associate editors. The new deputy editor is welcomed. The exemplary performance of the JMM in scholarly league-tables is registered. From this, a case is made for the pluralisation of the concepts of relevance and impact. In doing so, the emergent literature on critical performativity is unpacked. I highlight a missed opportunity in this material, namely, the potential for academics to act as critical commentators on industry practice in the courtroom. Developing the ideas associated with critical performativity leads to the scrutiny of new concepts in marketing. One of importance is positive marketing. This regressive manoeuver is critiqued; as is macromarketing narcissism. Following Dunne et al., I make a plea for more responsible academic practice. Developing logically from these ideas, a number of new potential avenues for contributing to the JMM are sketched. These include special sections and research notes among others.     

对大企业外部性问题的研究

在带来巨大经济效益和高速经济增长的同时,大企业的外部性问题因其大规模生产和消费对整个社会和自然环境造成了严重的负面影响。同时对外部性问题的监测手段和技术的不断提升,以及社会大众对外部性问题的强烈关注,迫使大企业在政府监管督促的基础上,应该发挥其主观能动性,积极将其外部性问题内化。     

我国城市居民最低生活保障制度发展与完善研究——以长沙市为例

我国城市居民最低生活保障制度是我国实施比较成功的一项社会救助制度。目前，长沙的低保制度在制度设计和运行方面仍存在消极的救助取向、平均式的救助标准、配套政策的负激励效应以及管理监督体系不健全等一些问题。为此，有必要对其进行探索改革，通过采取积极的福利政策、制定科学的保障标准，推行分类施助和差异救助、建立健全低保制度的管理监督体系等积极措施解决其存在的问题，更好地发挥最低生活保障制度的有效功能。     

Relationship between positive psychological capital and creative performance

Despite considerable attention to the creative process and its relationship with personal characteristics, there is no published study focused directly on the relationship between the recently recognized core construct of psychological capital (PsyCap) and creative performance. Drawing from a large (N = 899) and heterogeneous sample of working adults, this study investigates PsyCap and its components (i.e., efficacy, hope, optimism, and resilience) as predictors of creative performance. Overall PsyCap predicted creative performance over and above each of the four PsyCap components. Theoretical and practical implications of these findings are considered. Copyright © 2010 ASAC.
