In this paper we provide a sufficient condition for collusive outcomes in a single-shot game of simultaneous price choice
in a homogeneous product market with symmetric firms and strictly convex costs. We also prove the counterintuitive result:
if the second derivative of the cost function is nonincreasing in output, it is easier to sustain collusion when the number
of firms increases. 相似文献

Strategic Choice of the Price Structure and Entry Deterrence Under Price Cap Regulation 总被引:2,自引:0,他引:2
This paper shows that a price‐capped firm under the threat of entry in some of the markets it serves can strategically manipulate its price structure to deter entry. In doing so, the regulated firm uses the price cap constraint as a commitment device to an aggressive pricing behaviour in case of entry. A (dynamic) price cap generally entails that the prices allowed today are a function of the previous‐period prices and that the tighter is the constraint on each price, the larger is the quantity sold of this good in the previous period. Hence, the regulated firm may strategically choose its price structure before entry to place a tighter regulatory control on the prices set in the (potentially) competitive markets and to make it optimal to charge in these markets – in case of entry – prices so low that entry is unprofitable. 相似文献

In this paper we study the way a multiproduct firm, regulated through a dynamic price cap, can develop a price strategy that uses the regulatory policy to deter entry. We consider a firm that initially operates as a monopolist in two markets but faces potential entry in one of the markets. We conclude that the regulated firm can have the incentive to block the entry. This strategy leads to the reduction of the price in both markets. However, the final effect of the entry deterrence strategy on total consumer surplus is not always positive. 相似文献

This paper investigates how price regulation under moral hazard can affect a regulated firm's cost of capital. We consider stylized versions of the two most typical regulatory frameworks that have been applied in the most recent decades by regulators: Price Cap and Cost of Service. We show that there is a trade‐off between lower operational costs and a higher cost of capital under Price Cap regulation and higher operational costs and a lower cost of capital under Cost of Service regulation. As a result, when the extent of moral hazard is not significant, Price Cap regulation generates lower welfare than does Cost of Service regulation. 相似文献

基于价格上限的输配电价格管制模型改进研究 总被引:1,自引:0,他引:1
由于输配电环节具有自然垄断特性,因此必须接受监管,但随着电力的市场化改革,旧有的监管机制存在一定缺陷,而基于绩效的价格管制模型又不能直接适用于我国的国情。本文提出了一种基于价格上限的价格管制改进模型,在一般价格上限模型中引入电能质量因子,从而很好地克服了该模型导致质量恶化的缺陷,提高了模型的适用性。文中还详细介绍了电能质量因子的确定问题,并对该质量因子进行了算例分析。 相似文献

When a commodity market relies upon a regulated network service industry—e.g., telecommunications, electricity, or natural gas transmission—economic efficiency in that commodity market is a crucial consideration for regulatory design. This is because insufficient infrastructure investment relative to network demand results in congestion. The extraction of associated rents has distortionary effects on commodity spot market prices. Greater regulatory flexibility in network pricing can alleviate such issues by cultivating the incentives needed for stakeholders to invest in transmission capacity. To illustrate this effect I derive and numerically solve stylized optimality conditions for access and usage prices for a gas pipeline operator under alternative regulatory models. My results have general implications for regulation in network infrastructure industries, as energy and telecommunications markets are expected to expand considerably over the coming decades. 相似文献

产品差别化、价格战与合谋 总被引:2,自引:0,他引:2
随着中国市场化改革的不断深入,价格战成为各行各业企业间不断上演的舞台剧。文章旨在从产品差别化与企业间合谋的相互关系出发,来分析企业频繁选择价格竞争而难以进行合谋的原因,即产品垂直差别水平的降低将使合谋难以维持,价格战容易爆发。因此,解决价格战的途径之一是中国企业应该加大自主创新的能力,提高产品垂直差别化程度。 相似文献

Using the spatial price discrimination framework, the relationship between the locations of firms and their ability to collude
is investigated. Gupta and Venkatu (2002) show that in a duopoly model agglomeration at one point is the most stable location.
We find that agglomeration stabilizes the cartel when there are three firms, too. When there are more than three firms, however,
agglomeration of all firms is never the most stable location. With four firms, the following location pattern produces the
most stable cartel: two firms at one point and the other two at the farthest point from the first two. 相似文献

在药品市场竞争日益激烈的背景下,如何协调广告战略与研发战略之间的关系,提高创新药市场绩效成为制药企业面对的重要问题.本文构建双寡头制药企业的研发-价格竞争博弈模型,探究制药企业的广告战略、研发战略和政府价格管制政策对于不同类型企业研发激励、药品定价、市场份额、创新利润和创新药市场绩效的综合影响机制.研究发现,当且仅当广告投资和研发投入之间存在\"挤入\"效应时,实施广告战略才可能为企业带来竞争优势,但广告投资过大将导致企业利润的损失;其次,当且仅当广告投资效率较高时,实施广告战略才能增进创新药市场绩效;最后,价格管制政策和广告战略对企业利润产生综合影响,在一定条件下,价格管制能够强化广告战略对实施企业利润的增进效果,广告战略则有助于改善价格管制对实施企业市场份额的不利影响. 相似文献

We study regulation of the auditing profession in a model whereaudit quality is unobservable and enforcing regulation is costly.The optimal audit standard falls short of the first-best auditquality, and it is increasing in the riskiness of firms andin the amount of funding they seek. The model can encompasscollusion between clients and auditors, arising from the jointprovision of auditing and consulting services: deflecting collusionrequires less ambitious standards. Finally, banning the provisionof consulting services by auditors eliminates collusion butmay not be optimal in the presence of economies of scope. (JELClassification: G28, K22, M42). 相似文献

Regional transmission organizations (RTOs) have evolved from “power pool” arrangements between utilities to complex organizations that operate a region’s transmission system and power markets. These RTOs are administered with only peripheral public input. This paper reflects on how RTOs, as a result, have developed very complex market structures that few can or do understand. An RTO’s capacity construct is used to illustrate the point of this complexity and ad hoc nature. The paper also discusses reforms that are needed to align the RTOs behavior with Harry M. Trebing’s public interest regulatory philosophy. 相似文献

政府支出的目的之一就是改善人民群众的生活条件,增加居民收入。基于中国1980—2009年的时间序列数据进行实证研究,通过协整检验、Granger因果检验和误差修正模型的建立来分析政府基础设施投资支出与城镇居民收入的关系。结果发现政府基础设施投资支出与城镇居民收入具有长期的均衡关系,且政府基础设施投资支出是城镇居民收入的Granger原因(反向不成立)。 相似文献

Conventional net presentvalue calculations evaluating the profitabilityof investments in energy-saving technologies inDutch
horticultural outlays predict a muchhigher rate of adoption of these technologiesthan is actually observed. This paper tries
toexplain this gap by applying a real optionsframework. Hurdle rates for investments in twotypes of energy-saving technology
are estimatedusing simulated future revenue streams, givenuncertainty regarding energy prices and energytax policies. Hurdle
rates found in this wayare on average about 1.76 times the hurdlerates that result from net present valuecalculations. Furthermore,
this paper tests thepredictive value of the theory by estimating alogit model. This model relates the incidenceof having invested
in an energy-savingtechnology to the difference between the returnon investment and the hurdle rate. Thepredictive power turns
out to be encouraging,as the statistical tests indicate that higherhurdle rates tend to reduce rates of technologyadoption. 相似文献
