Spatial Evolution of Social Norms in a Common-Pool Resource Game

We study the conditions for the emergence of cooperation in a spatial common-pool resource (CPR) game. We consider three types of agents: cooperators, defectors and enforcers. The role of enforcers is to punish defectors for overharvesting the resource. Agents are located on a circle and they only observe the actions of their two nearest neighbors. Their payoffs are determined by both local and global interactions and they modify their actions by imitating the strategy in their neighborhood with the highest average payoffs on average. Using theoretical and numerical analysis, we find a large diversity of equilibria to be the outcome of the game. In particular, we find conditions for the occurrence of equilibria in which the three strategies coexist. We also derive the stability of these equilibria. Finally, we show that introducing resource dynamics in the system favors the occurrence of cooperative equilibria.      

FTPL-Perspective on Tradable Deficit Permits in the EMU

The Growth and Stability Pact restricts member states in their fiscal policy but also causes inflexibility in the pursuit of wide-ranging economic and social reforms. Tradable deficit permits allow more flexibility for individual member states and provide a stick for those who exceed the deficit limit but also a carrot to those who stay below it. But does the trade in deficit permits affect the monetary objectives of the European Central Bank (ECB)? We argue that from a perspective of fiscal theory of the price level, trade in deficit permits can lead to higher inflation depending on the growth rate and the debt/GDP ratio of the member states.

Karl Pearson and the Scandinavian School of Statistics

The relationship between Karl Pearson and the Scandinavian statisticians was more of a competitive than a collaborative nature. We describe the leading statisticians and stochasticists of the Scandinavian school, and relate some of their work to the work of Pearson.     

Here come the men in black Technology and anxiety in the postmodern age

This review of the film Men in Black argues that what used to be alarming in the science fiction genre has now become its main source of humour. As a reactionary response to the dystopic X-Files, MiB is an elaborate parody which seeks to recuperate ideological ground lost by the X-Files' examination of gender and technology in contemporary culture. Anxiety about the roles of technology, gender and the state are replaced by humour about the notion of anxiety itself. Anxious we may be at the close of the millenium, but MiB tells us to just laugh it all away.     

基于经济理论的高校大学生诚信道德教育

近些年来,高校大学生诚信缺失与道德现状越来越受到教育界和社会公众的关注,这无疑提醒我们高校大学生需要诚信道德教育。从经济理论出发,对高校大学生诚信缺失进行博弈分析,探究其深层次原因,基于道德与经济的一致性的理论,将经济理论中的微观均衡理论、效用最大化规律、机会成本理论、收益与责任对称理论与诚信道德教育结合,提出大学生诚信道德教育的新理念。     

MONEY,OUTPUT AND INFLATION IN AFRICAN ECONOMIES1

This paper examines the long‐run money‐inflation relation for 36 African countries using cross‐section and panel data analysis. The focus is on the recent claim by De Grauwe and Polan that the common finding in multi‐country studies of a strong positive link typically reflects the presence of high‐inflation countries in the sample and on Nelson's criticisms of the data and methodology employed in that study. Adjusting the De Grauwe and Polan methodology to take account of many of Nelson's criticisms, I confirm a weak long‐run relation between money growth and inflation for countries when money growth and inflation are below 10%, but a strong relation when money growth and inflation move much above that number. This result is not dependent on the inclusion of high inflation countries in the cross‐section and panel data samples.
