清洁发展机制及其对我国可再生能源发电的启示

清洁发展机制（CDM）是近几年来国际社会的热门话题，本文从走循环经济道路和建立环境友好型社会出发，结合清洁发展机制，从各方面分析了我国可再生能源发电的现状和CDM项目的市场潜力及优势。进而根据目前我国CDM项目的开发情况分别从微观和宏观两个层面提出了一些建议，如选择合适的融资方式、强化政策体系的建设与创新、提高国际谈判能力和建立CDM联系机制等。     

Corruption,market quality,and entry deterrence in emerging economies

In many emerging economies incumbent firms often use dubious means to deter entry of other firms. We analyze this scenario in a three‐stage game of entry deterrence. The incumbent has incomplete information about the entrant's costs but can increase this cost by resorting to unfair means (e.g. bribing a politician who harms the entrant). We completely characterize the optimal bribe and show that this depends on the “fairness index” and the “differentiation” parameter. We also show that zero bribes need not maximize welfare and market quality. Our results seem to be compatible with anecdotal evidence from emerging economies such as India.

Cournot–Bertrand comparisons under R&D competition: Output versus R&D subsidies

We compare Cournot and Bertrand competitions with R&D investment under output versus R&D subsidy policies. We demonstrate that Cournot firms invest more (less) in R&D and the government grants more (less) subsidies than for Bertrand firms with output (R&D) subsidies. We also find that both competition modes yield the same welfare with output subsidy, while Bertrand yields higher welfare than Cournot with R&D subsidy. Finally, firms' profits and welfare in Cournot are higher under output subsidies, while they can be higher in Bertrand under R&D subsidies if the product substitutability is high and the firm's R&D investment is efficient.     

Do oligopolistic firms benefit from being forced to act non-strategically?

The present study seeks to answer the question of whether acting non-strategically can benefit firms. In a static Cournot framework, if a subset of firms are constrained to the equilibrium level of output, being non-strategic will have no impact on profits of neither constrained nor strategic firms and provided that sufficiently large number of firms are restricted, a marginal quantity contraction can be to their benefit. In contrast, using a dynamic Cournot framework, we find that the constraint set at the equilibrium level or moderately deviated from it, leads to increased profits for all firms irrespective of the number of non-strategic ones.     

第三方负责回收的再制造闭环供应链效率分析

研究了在两个销售商进行古诺竞争的情况下,第三方负责回收的再制造闭环供应链收益,分别讨论了生产商占统治地位和销售商占统治地位时对结构效率的影响。结果表明,回收价格是回收行为的驱动因素,回收价格越低,第三方回收努力系数越大,且社会总剩余越大;与销售商占统治地位相比,生产商占统治地位时存在效率损失;通过契约先谋求供应链的整体收益最大,然后根据契约规定的比例进行收益共享,不仅实现了供应链成员的共赢,而且实现了社会总剩余最大。     

Environmental Taxation and Vertical Cournot Oligopolies: How Eco-industries Matter

This article specifies what an optimal pollution tax should be when dealing with a vertical Cournot oligopoly. Polluting firms sell final goods to consumers and outsource their abatement activities to an environment industry. It is assumed that both markets are imperfectly competitive. Thus, the tax is a single instrument used to regulate three sorts of distortions, one negative externality and two restrictions in production. Consequently, the optimal tax rate is the result of a trade-off that depends on the firms’ market power along the vertical structure. A detailed analysis of Cournot-Nash equilibria in both markets is also performed. In this context, the efficiency of abatement activities plays a key-role. It gives a new understanding to the necessary conditions for the emergence of an eco-industrial sector.

Transportation rates and plant location in oligopolistic competition with sequential entry

This paper examines the impact of quantity-discounted transportation rates on location patterns of oligopolistic competition with sequential entry. When transportation rates are constant, Hwang and Mai (1990) show that the entrant locates at the same point as the existing firms if the production function exhibits constant returns to scale. The entrant will locate farther away from (closer to) the market than the existing firms do if the production function exhibits increasing (decreasing) returns to scale. This paper shows that Hwang and Mai's results need not hold when transportation rates are a function of quantity shipped and distance traveled.
