Utility Regulation and Risk Allocation: The Roles of Marginal Cost Pricing and Futures Markets

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.     

Collusive Long-Run Investments Under Transmission Price-Caps

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.     

地价杠杆在城市经营中的调控作用——以南京市为例

本文紧密结合经营城市这个热点问题，首次系统地阐述了地价杠杆在城市经营中的重要作用。并结合南京市1998－1999年的土地出让实际工作成果，运用文中提出的观点，设立不同的口径进行详细分析与对照。通过综合分析与尝试，一方面，说明地价杠杆在政府经营城市的过程中具有不可替代的地位；另一方面，城市政府完全可以运用地价杠杆的经济特性，趋利避害，更好地促进国民经济的健康有序发展。     

房地产价格风险：国际教训、中国的现状及路径选择

房地产泡沫会增加金融风险,房价大幅缩水会导致银行破产,股市下跌。日本、美国、英国、泰国等都爆发过与房地产相关的银行危机。目前,中国房地产金融具有市场风险、财务风险、道德风险和信用风险等潜在风险。应利用税收手段限制投机性购房和短期炒作行为,鼓励中小户型住房的消费,加强城镇廉租住房制度建设,防范“假按揭”风险,完善惩戒机制,加强利率风险管理,完善住房置业担保制度,进一步研究制定房贷保险制度。

论我国饭店的等级划分与价格管理

在现实市场中,为了方便对酒店进行监督和管理,也为了不同层次消费者的需要,政府往往根据不同的硬件设施标准和软件服务水平对酒店进行等级划分;同时,由于我国旅游市场的外部性因素,政府又根据相应的标准对其进行一定的价格管制, 实行限价,藉此保护消费者,但是这会对消费者和经营者产生影响。     

Researching Preferences,Valuation and Hypothetical Bias

A number of recent papers in environmental economics have focused on the process of researching preferences – agents are uncertain about preferences but with effort may narrow their uncertainty. This issue has arisen in formulating bids in contingent valuation (CV) as well as the debate over the divergence between WTP and WTA. In the context of CV, it has been suggested that the hypothetical nature of the preference elicitation process biases responses. This paper provides both a theoretical model and experimental evidence to contribute to this debate. The model is a model of competitive bidding for a private good with two components that are particularly relevant to the debate. The first component is that bidders are unsure of their own value for the private good but may purchase information about their own value (researching preferences). The second component is that there is a probability that the auction is hypothetical – that the winning bidder will not get the private good and will not pay the winning bid. The experiment tests this theoretical model of bidding equilibrium and analyzes the effects of variations in the parameters (hypotheticalness, information costs and number of agents) on the endogenous variables (such as the proportion of bidders who become informed and the winning bid). Experimental results suggest that an increase in the hypotheticalness of an auction tends to decrease the likelihood that bidders pay for information on their valuation with an ambiguous effect on the winning bid.      

全国及各省居民消费物价指数变化的同步性分析——基于2000年1月-2006年6月月度数据的一个比较

本文主要基于月度数据使用滤波分析方法分析省际CPI的同步性.指出:大部分省CPI与全国基本平行运行,而且随着全国市场一体化程度的不断提高,同步性会进一步增强,产生差异的将是CPI的波动幅度和个别省运行上的领先或者滞后.因此,我国宏观调控必须坚持全国一盘棋,有效调控总量.同时,在尊重市场规律的前提下,在科学的范围内谨慎探索"突出重点,有保有压,区别对待"的实践.     

会计价值机制论

本文认为,市场和企业是组织经济活动的形式,也是组织价值信息传递和价值激励的系统。市场价格机制是在长期市场供求关系作用下而形成的,而会计价值机制是随着企业的发展不断演化,在企业目标引导下组织价值信息传递和价值信息激励,以促成企业目标实现。企业替代市场或取得竞争优势,都是基于相同的原因和两种机制作用的结果,即是通过企业提供的产品或服务的成本低于市场价格而实现的。
