强自然垄断定价理论与中国电价规制制度分析

强自然垄断行业由于其定价方面的两难困境 ,需要规制者对其产品定价进行规制以在厂商利润与社会福利之间进行权衡。边际成本定价原则并不适合于自然垄断厂商。本文在规制定价理论以及激励规制理论的基础上 ,对中国电力定价问题进行了分析 ,认为电价改革的第一步应在发电环节中引入竞争的基础上 ,对不同效率类型的电力厂商设计不同激励强度的定价机制 ,另外本文尝试着对不同技术效率的电力厂商列出了不同激励强度的价格规制方案菜单     

The Law of One Price—A Case Study

We use retail transaction prices for a multinational retailer to examine the extent and permanence of violations of the law of one price. For identical products, we find typical deviations of 20–50 percent, with some evidence for convergence over time. Such differences might be due to differences in local costs. If so, relative prices of similar products (round versus square mirrors) should be equal across countries. In fact, relative prices vary significantly across very similar goods within a product group. The finding suggests that differences in local distribution costs, local taxes, and probably tariffs do not explain the price pattern, leaving strategic pricing or other factors resulting in varying markups as alternative explanations.

Optimal price setting during a currency changeover: theory and evidence from french restaurants

This article studies firms’ price-setting decision during a currency changeover. Buyers’ difficulties with the new nominal price level may create incentives to raise prices temporarily but doing so comes at the risk of damaging a seller’s standing as a fair retailer. We model firms’ trade-off and study conditions under which increasing or decreasing prices is optimal. A difference-in-differences analysis based on micro-data of French restaurants strongly supports the model’s predictions. Prices during the 2002 changeover in the European Monetary Union were less likely to rise in larger restaurants, nontourist restaurants and when prices were advertised.     

Stylised features of consumer price setting behaviour in Portugal: 1992–2001

This paper identifies the empirical stylized features of consumer price setting behavior in Portugal using two micro-datasets underlying the consumer price index. The main conclusions are: one in every four prices change each month; there is a considerable degree of heterogeneity in price setting practices; prices of goods change more often than prices of services; price reductions are common, as they account to around 40% of total price changes; price changes are, in general, sizeable; finally, the price setting patterns seem to depend on the level of inflation as well as on the type of outlet.

城市湖景对住宅价格的空间影响——以杭州西湖为例

城市湖泊具有重要的景观生态价值,对住宅价格的影响显著,一直受到国内外学者的关注。以杭州西湖为例,采用2011年杭州市6城区649个住宅小区的相关数据,建立传统特征价格模型,并从方向—距离异质性两个维度对模型进行改进,实证分析城市大型景观中心对住宅价格的空间影响差异。结果表明:①西湖对杭州市住宅价格具有显著的正向外部性效应,到西湖的距离每增加1%,住宅价格将下降0.226%。②西湖对住宅价格的影响存在显著的方向异质性,平均的空间影响范围为5.62km,但在不同方向上西湖的价格弹性呈现明显差异。③在以西湖为中心、同心圆状向四周扩散的过程中,住宅价格对西湖距离的空间敏感性呈现出先急剧减小后缓慢增大的趋势。     

自然资源的定价理论和定价方法研究

Sticky prices or rational inattention – What can we learn from sectoral price data?

This paper derives stylised facts on sectoral inflation dynamics and confronts these facts with two popular theoretical models of price setting. Based on sectoral price responses to macroeconomic shocks estimated from an approximate factor model, we find that the frequency of price changes explains a relevant share of the cross-sectional variation of the speed and size of responses. Moreover, there is little evidence that the volatility of sectoral inflation due to idiosyncratic shocks dampens the size and speed of the responses to macroeconomic shocks. These findings support a multi-sector model with sticky prices rather than a rational-inattention model. We derive the results from different modelling and sampling decisions proposed in the literature, and we find that the explanatory power of the frequency of price changes for the speed of response to a macroeconomic shock proves robust in the face of these decisions. Other results are sensitive with respect to the choice of the factor model and the treatment of outliers.     

Cartel Stability in a Delivered Pricing Oligopoly

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.

可持续发展视角下自然资源价格构成的进一步研究

自然资源是人类赖以生存和发展的重要物质基础和经济基础。在资源枯竭和环境污染日益严重的今天,必须重新认识自然资源的价格。文章从可持续发展的视角研究了自然资源的价格构成成分及其相互之间的关系,提出自然资源的价格由内部价值和外部性成本构成,内部价值包括天然价值和人工价值,外部性成本包括环境成本、生态成本和代际补偿成本。只有清楚认识自然资源的价格构成及其关系,才能为自然资源的定价提供客观科学的依据。

Understanding changes in exchange rate pass-through

Recent research suggests that there has been a decline in the extent to which firms “pass-through” changes in exchange rates to prices. This paper provides further evidence in support of this claim. Additionally, it proposes an explanation for this phenomenon. The paper then presents empirical evidence of a structural break during the 1990s in the relationship between the real exchange rate and CPI inflation for a set of fourteen OECD countries. It is suggested that the recent reduction in the real exchange rate pass-through can in part be attributed to the low inflationary environment of the 1990s.     

城市化时空预测模型初探

城市化过程实质上是城市文明的时空扩散过程。传统的城市化预测模型多着眼于时间,文章在空间扩散模型的基础上,尝试在城市化预测模型中同时考虑时间维和空间维,提出城市化时空预测模型,如时空相互作用模型、空间—时间自相关模型、内生潜力与外生潜力相结合模型等,从而提供预测城市化进程的新视角和新思路。     

要素空间优化、宏观经济增长与物价稳定

确保经济长期平稳增长和物价持续稳定往往是传统财政政策和货币政策难以兼顾的预期目标.经济事实,尤其是最近一年过山车式的国内外经济形势告诉人们,高通货膨胀压力与高经济增长、通货紧缩威胁与经济衰落总是如影随形.经济一旦衰落就很难恢复,高通胀预期一旦形成,就很难使其下降.由此形成了系列两难困境,并使宏观调控趋于无效或低效.为摆脱这种困境,文章从空间视角下提出空问优化理论.研究发现,在空间优化理论指导下,运用空间优化政策能解决这种两难问题.这将为宏观调控在运用财政政策和货币政策解决实际经济问题时,提供了崭新的政策选择.     

Teaching the Minimum Wage in Econ 101 in Light of the New Economics of the Minimum Wage

The author argues that the recent controversy over the effect of the minimum wage on employment offers an opportunity for teaching introductory economics. Research findings on the minimum wage could be used to motivate alternative models of the labor market, such as monopsony and search models, and to teach students how economists test hypotheses with data.
