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.

人力资本产权化的经济效应分析 总被引:9,自引:0,他引:9
赵珍 《山西财经大学学报》2006,28(1):12-16
人力资本理论与产权理论相结合,形成了一个新的研究领域,即人力资本产权理论。人力资本产权化,即实现人力资本产权的过程,就是在承认资本非同质性、强调人力资本在生产实践中重要地位的前提下,赋予劳动者与其人力资本相对应的产权权能、权益和权责的过程。实现人力资本产权化,赋予劳动者与其人力资本对等的产权,提高了劳动者的工作积极性,这对完善经济体制,提高经济运行质量,具有重要意义。 相似文献

We show how credible revelation and ability to commit to quality choice effect equilibrium qualities and welfare when product
market is either Bertrand or Cournot competition. We show that results depend on the type of competition but not generally
on the cost of quality function. We show that with Bertrand competition, the equilibrium qualities are lower with credible
commitment. Competition is moderated and producer surplus is higher and consumer surplus lower. With Cournot competition,
higher quality will be better but lower quality will be worse with credible commitment. Consumer surplus is always greater
with credible commitment and if cost does not increase too quickly with quality, producer surplus will also increase. Thus
credible commitment is a collusive device with Bertrand competition but it can improve social welfare with Cournot competition.

This paper reports an experiment designed to assess the effects of a rotation in the marginal cost curve on convergence in a repeated Cournot triopoly. Increasing the cost curve's slope both reduces the serially-undominated set to the Nash prediction, and increases the peakedness of earnings. We observe higher rates of Nash equilibrium play in the design with the steeper marginal cost schedule, but only when participants are also rematched after each decision. Examination of response patterns suggests that the treatment with a steeper marginal cost curve and with a re-matching of participants across periods induces the selection of Nash Consistent responses. 相似文献

中国外汇储备投资组合选择——基于外汇储备循环路径的内生性分析 总被引:8,自引:0,他引:8
本文从中美两国经济的本质性差异出发,通过刻画中国外汇储备对外投资的"循环路径",构建了包括央行、金融市场和实体经济的斯塔克尔伯格及古诺模型,进而模拟出中国外汇储备对外投资对本国经济的间接贡献、合意的外汇储备投资组合,以及最优外汇储备投资规模。研究结果表明,中国外汇储备投资于美国风险资产的规模将影响外汇储备间接转化为美国对中国FDI的比例。同时,中国央行外汇储备规模及投资策略对危机时期的反应不足。改变外汇储备投资收益的主要方法包括降低居民的相对风险回避系数,通过政策引导促进居民消费,以及大力发展中国金融市场,降低对美国金融市场的依赖程度。 相似文献

Unilateral abatement is sometimes advocated in order to set a good example that will make other countries follow. The aim
of this paper is to investigate whether existence of correlated cost uncertainty provides an incentive for a country to undertake
unilateral abatement. The theoretical model is driven by two main mechanisms; first, a learning effect, as the follower country
might reduce its risk premium as it can observe the cost level in the leader country. Second, there is the public good effect,
i.e., the marginal benefit of abatement declines when abatement is a public good and other countries contribute to pollution
reductions. Results shows that unilateral abatement would be efficient in reducing uncertainty about the unit costs of abatement
if a country with low cost uncertainty would undertake abatement first, while a country with initially high cost uncertainty
would follow. However, countries may prefer to act simultaneously because of the larger uncertainties that are inherent in
a sequential game.

本文讨论了存在成本差异的第三国市场模型的最佳贸易与产业政策选择问题,讨论了社会成本和私人成本、本国和外国成本差异情况下的Cournot竞争和Bertrand竞争的情况。本文发现,在Cournot竞争下,政府首先行动时,当政府基金影子价格低于4/3时,政府对出口进行补贴,并且本国越有成本优势,补贴越高,补贴的利润转移效应越大;当政府基金影子价格高于4/3时,政府对出口征收出口税,且本国越有成本优势,征税越多。在Bertrand竞争下,当政府先行动时,对出口征收出口税;当政府后行动时,对出口进行补贴。当本国企业具有劣势时,事后补贴是最佳政蓑。 相似文献
