“保证最低价”是商业企业在市场竞争中经常运用的竞争策略。本文将家乐福和欧尚两家大型超市“保证最低价”的策略行为界定为企业间一种默契式的价格协调行为。通过市场调查和博弈分析,我们得出在价格效应上“保证最低价将形成统一低价”的结论。并进一步分析了这一策略行为对两家企业自身、对超市业以及对社会福利等方面的影响,进而提出了政策建议。 相似文献

随着粮食生产经营的全面市场化,健全和完善粮食期货市场有了更重要的现实意义:调节粮食供求,稳定粮食价格;优化粮食品种结构,推动产业化经营;为粮食企业提供避险渠道;减轻入世冲击,保护粮食安全。文章指出发展粮食期货市场的政策措施包括:推出大宗粮食期货交易品种;培育和发展套期保值用户;规范粮食现货市场;发展商品投资基金;开创场外交易;调整不符合国际惯例的法规政策。 相似文献

新<公司法>增加了股票回购事由的条款,放宽了对股票回购的限制.但在股票回购的立法方面,总体上仍较为简单、粗略,缺乏具体的操作规则,没有形成完整、严密的规制体系.由于立法模式的差异,各国对股票回购过程中内幕交易及股价操纵行为的管制形式也有所不同.对欧美等国对股票回购过程中的内幕交易和股价操纵行为的监管进行比较分析,可以为我国股票回购实施过程中如何抑制股价操纵行为提供启示. 相似文献

配股融资股价效应的实证研究 总被引:2,自引:0,他引:2
随着我国股市的发展,上市公司的融资方式也不断创新,配股融资作为股权融资的一种方式逐渐成为上市公司再融资的首选。配股融资虽然具有许多优点,但是我国上市公司没有充分发挥配股融资的长处,为了“圈钱”而“圈钱”,并且资金配置效率低下,对股市的负面影响日渐突出。通过2000年实施配股的43家样本公司配股公告日股价的变动,对配股融资的股价效应进行实证分析,并提出相应的政策建议。 相似文献

以中国“沪港通”交易制度的实施为政策背景,采用多时点双重差分模型,考察资本市场开放对标的公司内部控制质量的影响,研究发现,“沪港通”交易制度的实施显著提升了公司的内部控制质量,在控制其他因素并经过安慰剂检验、去除A+H股影响、改变周期范围等稳健性检验后,结论依然成立。机制检验表明,“沪港通”主要通过内部和外部两种机制对公司内部控制质量产生影响,其中,内部机制是对股价波动性风险控制,外部机制是审计师声誉风险与政府部门监管。 相似文献

Although oil spills from tanker accidents receive the most publicity, most vessel spills are not the result of accidents but of oil transfer activities. We investigate determinants of the size of vessel oil transfer spills as well as the effectiveness of Coast Guard enforcement activities in reducing their size. Vessel out-of-water and in-water oil transfer spillage functions are estimated utilizing tobit regression and detailed data on individual vessel oil transfer spills as well as Coast Guard safety/environmental enforcement activity data for the 1991–1995 period. Our estimation results suggest that Coast Guard hull but not machinery inspections are effective in reducing both out-of-water and in-water spills; patrols by air, but not by boat, are effective in reducing out-of-water spills; but neither is effective in reducing in-water spills. The results also show that the type of vessel (oil- and non-oil-cargo), vessel characteristics, vessel operations, weather/visibility conditions, and waterway type are determinants of post OPA-90 vessel oil transfer spills. 相似文献

Noisy chaotic dynamics in commodity markets 总被引:2,自引:1,他引:2

The nonlinear testing and modeling of economic and financial time series has increased substantially in recent years, enabling us to better understand market and price behavior, risk and the formation of expectations. Such tests have also been applied to commodity market behavior, providing evidence of heteroskedasticity, chaos, long memory, cyclicity, etc. The present evaluation of futures price behavior confirms that the resulting price movements can be random, suggesting noisy chaotic behavior. Prices could thus follow a mean process that is dynamic chaotic, coupled with a variance that follows a GARCH process. Our conclusion is that models of this type could be constructed to assist in forecasting prices in the short run but not over long run time periods.First version received: June 2001/Final version received: March 2003 相似文献

The effects on consumer welfare of requiring a utility facing cost or demand risk to use either a fixed retail price or marginal cost pricing are assessed. With marginal cost pricing and cost volatility an efficient futures market allows consumer welfare to be at least as high in every state as with the fixed price. With demand risk marginal cost pricing can benefit the consumer in every state without harming the firm if the profit difference is transferred to the consumer. A futures market can act as a partial replacement for the transfer. 相似文献

In the short run, constraints in the electricity transmission system may give market power to generators. This paper examines whether the constraints themselves are a long-run equilibrium outcome in a competitive environment. We show that independent transmission companies and generators can tacitly collude to raise prices to consumers and divide the resulting profits. We also show that price cap regulation does not prevent this behavior and may in fact contribute to it. The mechanism for collusion is that generators locate their plants so that a capacity-constrained transmission line lies between them and their consumer market. We show that this constraint-based collusion can be sustained in a static game without any punishment strategies. 相似文献
