A DYNAMIC ENTRY AND PRICE GAME WITH CAPACITY INDIVISIBILITY

Strategic market interaction is here modelled as a two‐stage game in which potential entrants choose capacities and next active firms compete in prices. Due to capital indivisibility, the capacity choice is made from a finite grid and there are economies of scale. In the simplest version of the model with a single production technique, the equilibrium turns out to depend on the ratio between the level of total output at the long‐run competitive equilibrium and the firm's minimum efficient scale: if that ratio is sufficiently large (the market is sufficiently ‘large’), then the competitive price emerges at a subgame‐perfect equilibrium of the capacity and price game; if not, then the firms randomize in prices on the equilibrium path. The role of the market size for the competitive outcome is shown to be even more important if there are several available production techniques.

以公司利益为主:公司治理应有的价值取向

公司治理是公司生命机体的核心和灵魂,有效的公司治理取决于公司治理科学合理的价值取向。以经济和法律的视角来看,股东利益最大化、关注利益相关者等价值取向都有各自的矛盾,公司治理应坚持以公司利益为主的价值取向。     

When good conflict gets better and bad conflict becomes worse: the role of social capital in the conflict–innovation relationship

This research investigates the moderating effect of social capital on the conflict–innovation relationship and poses the argument that social interaction amplifies the beneficial effect of task conflict and the harmful effect of relationship conflict, whereas trust suppresses these effects. Analyses of a sample of 232 Canadian-based firms demonstrate that at higher levels of social interaction, the positive relationship between task conflict and innovation is stronger, and so is the negative relationship between relationship conflict and innovation. Furthermore, at higher levels of trust, the positive relationship between task conflict and innovation weakens. This study adds to the emerging contingency perspective pertaining to the study of conflict and provides a more nuanced view of the beneficial role of intra-organizational social capital for innovation.     

Ex Post Evaluation of Enforcement: A Principal-Agent Perspective

Summary  This paper discusses a number of methodological challenges that ex post evaluation of competition policy faces. We argue that imprecise measurement and simplified analysis not only lead to unreliable results, but also trigger behavioural responses by competition authorities. Because evaluation works as an incentive scheme, it has an immediate impact on the way agencies operate. Faced with simplistic assessment, authorities may be tempted to be overly interventionist, to spend too many resources and to ignore relevant information. Therefore, a careful design of methodologies is important to ensure that ex post control does not bring about the very ills it is supposed to cure. The views expressed are those of the authors and do not necessarily reflect those of DG Competition or the European Commission.     

The affectionate society: does competition for partners promote friendliness?

We study household formation in a model where collective consumption decisions of a household depend on the strategic choices of its members. The surplus of households is determined by individual choices of levels of friendliness to each other. A strategic conflict arises from a coupling condition that ceteris paribus, a person’s friendlier attitude reduces the individual’s influence in the household’s collective decision on how to divide the ensuing surplus. While partners in an isolated household choose the minimum level of friendliness, competition for partners tends to promote friendliness. We find that affluence does not buy affection, but can lead to withholding of affection by an affluent partner who can afford to do so. In general, the equilibrium degree of friendliness proves sensitive to the socio-economic composition of the population. We would like to thank Clive Bell, Edward Glaeser, Roger Lagunoff, Eva Terberger and seminar audiences in Berlin, Birmingham, Blacksburg, Exeter, Heidelberg, Manchester and at IHS in Vienna for helpful comments. We greatly appreciate the thoughtful comments of a referee.
