规制分权化对电力行业发展的影响:基于中国省级面板数据的经验研究

本文主要讨论了中国当前规制分权化背景下的地方规制机构与被规制企业之间的合谋问题,而合谋会导致规制低效率。基于面板数据,利用固定效应估计法对1998～2003年规制分权化的效果进行经验研究,结果表明规制分权化没有产生正面效应。因此,本文认为解决问题的关键是机制设计。

成品油税费改革对公路客运企业定价影响的经济学分析

成品油税费改革对公路客运企业定价的影响主要体现在对公路客运企业运输成本的影响。通过对公路客运企业运输成本构成的分析,说明成品油税费改革对公路客运企业的定价会产生较大的影响,进而对不同车型的车辆运输成本变化进行了计算,分析出其运行里程的平衡点,设计出成本变化计算模型,可以使客运企业能较为方便、准确的判别自身运输成本的变化幅度。根据客运企业受影响的程度,可以采取争取政策支持、优化车型结构和线路等对策,尤其是针对中小型客运企业,提出了实行自由连锁这一创新模式,以促进企业自身和交通市场的良性发展。     

Pricing on the Internet

It is often claimed that e-commerce has created a more competitiveenvironment by encouraging the entry of new online firms andby enabling buyers to search easily for the lowest prices. Thelimited evidence that exists paints a mixed picture. Many onlinemarkets are advertising- and technology-intensive, creatinga tendency towards growing concentration. Price search is imperfectand firms can dampen price competition by increasing productheterogeneity and switching costs. In many sectors, online firmsmay come to acquire some market power. We look at the formsof pricing that are likely to emerge in such markets, includingthe greater use of price discrimination and auction-like tradingarrangements.     

我国盐业体制困境的根源与焦点——基于盐价与利益主体的分析

我国盐行业的经济规模小、技术装备落后、资源利用率低和经济效益差等结构性矛盾及问题比较突出,其根源在于行政垄断、政企不分的专营管理体制,焦点集中在盐价的政府定价机制,导致整个盐业管理体制混乱、产能严重过剩、产业结构不合理和国际竞争能力低下。文章认为,解决盐业体制的关键在于改革当前的行政管理体制和专营模式,从国家层面修改或重新制定盐业的相关法规,规范相关政府职能部门的管理权责,引入市场竞争主体,形成良好的市场秩序,将盐业体制纳入科学管理的轨道。     

Pricing in the hotel and catering sector

Summary A model explaining gross margins in the hotel and catering sector is developed. A cost-mark-up model for the retail sector is used as a starting point. Although we have to reject the hypothesis of mark-up pricing in the hotel and catering sector, the model proves a useful instrument to discriminate between such influences as sales composition, costs and their various components, scale and demand conditions on price setting. Our empirical evidence stems from the Dutch hotel and catering sector (1977 through 1981).We are extremely grateful to the Central Bureau of Statistics (particularly the Department of Interior Trade and Commercial Services) in Voorburg, The Netherlands for permitting the use of their data under certain secrecy conditions.     

Livestock Pricing in the Northern Kenyan Rangelands

This paper uses detailed, transactions-level data and an innovative,structural-heteroskedasticity-in-mean estimation method to identifythe determinants of livestock producer prices for pastoralistsin the drylands of northern Kenya. The empirical results confirmthe importance of animal characteristics, periodic events thatpredictably shift local demand or supply and, especially, rainfallon the prices pastoralists receive for animals. Price risk premiaare consistently negative in these livestock markets. The impositionof quarantines has a sharp negative effect on expected producerprices in the pastoral areas, revealing that Kenya's approachto animal disease control favours wealthier highlands ranchersand consumers at the expense of poorer drylands herders.
