The Dark Side of Information and Market Efficiency in E‐Markets*

Price dispersion reflects the differences in prices for identical products. While in physical markets such dispersion is prevalent due to high search costs, many researchers argue that search costs and price dispersion will be much lower in electronic markets (e‐markets). Empirical evidence does not support this contention, and researchers have studied search costs, market factors, and service‐quality factors to explain this dispersion. Previous research has largely assumed that more information is better. By ignoring the dark side of information, we argue that only a partial understanding of price dispersion is possible. In this article, information overload and equivocality are studied as two dark attributes of information that lead sellers to different pricing decisions in e‐markets. Hypotheses relating these attributes to price dispersion are supported through analysis of 161 product markets. This work opens up new avenues in the study of e‐markets and discusses the implications of these findings for research and practice on consumer and seller decisions.     

浅议价格审计在企业管理中的作用及实施

我国的内部审计正面临从过去的合规性监督向管理性监督转换。价格审计通过对企事业单位物资购销价格、投资成本和工程造价等进行审计 ,强化企业的内部监督管理、有效控制企业的经营成本 ,是我国企业现阶段实现内部审计管理职能、提高企业管理水平和增进经济效益的有效手段     

当前的价格形势及政策抉择

当前,我国居民消费价格（CPI）高位继续上涨,工业品出厂价格（PPI）和固定资产投资价格加速上涨,房地产和股票等资产类价格出现滞涨和大幅回落态势。本轮价格上涨是在全球性需求比较旺盛、资金比较宽裕的背景下,主要是由于成本上升及供给不足推动的,即供给环节问题是导致当前我国价格上涨的直接原因。为此,宏观调控的政策重点应是控信贷、保供给、抑通胀。     

我国物价变动的影响因素及其传导机制的实证研究

内容提要:本文主要研究宏观经济变量对价格水平的影响,上下游物价之间的传导机制以及经济变量变化的时滞关系,着重考察相关经济变量之间是否存在因果关系,先行关系以及刻画影响程度的脉冲响应。实证结果表明,在影响物价的因素方面,工业增加值,投资,消费,进口与出口以及M1,M2均为CPI的原因,但财政支出与贷款增量不是CPI的Cranger原因,其中工业增值,M1和进口,出口还是领先于CPI变动的稳定的先行指标;在物价传导方面,市场化程度较高的领域,价格传导畅通,而垄断行业或政府控制部门价格传导不畅或严重时滞。     

The impact of India’s food security policy on domestic and international rice market

Food security policy making in India is at crossroads. India has emerged as a leading rice exporter. The Government of India has introduced the National Food Security Act which requires 33.6 million tons of rice per year for its public food distribution system. In this study, we modeled India’s rice market and analyzed policy implications of the long-term impact of India’s food security act on domestic and international rice market. We developed a structural economic demand and supply model for India’s rice market and further added subsidy equations to trace the consequence of National Food Security Act on domestic rice consumption and on the international market. We specifically focus on three different scenarios: subsidy as price effect, subsidy as inelastic income effect, and subsidy as elastic income effect under the broader framework of National Food Security Act. We found that at the end of the projection period (2024–2025), as a result of rice subsidy program, the consumption of rice increases significantly in the case of price effect while the inelastic income effect has no or less impact on production, consumption, and export of rice. Hence, the policy implication of our study is that if the objective of the National Food Security Act is to increase consumption then it needs to be implemented as price effect.

价格梯度对降低普通农产品非绿色投入的探讨

侧重于普通农产品绿色化过程中价格的讨论,提出针对普通农产品的非绿色化程度进行价格上的区分可以降低生产者对作物的非绿色投入,然而现实普通农产品市场中的信息不对称所产生的“柠檬效应”阻碍了这种机制的有效运行。利用Java Swarm建立Agent仿真模型得出严格监督上述价格上的区分并适当提高消费者对市场上普通农产品的信任度是可以解决该问题的。由此建议建立普通农产品价格与绿色化程度的关联机制及配套相关措施。

An Analysis of the Peer Effects in Charitable Giving: The Case of Taiwan

The purpose of this study was to utilize the data from the Survey on Family Income and Expenditure in Taiwan to investigate the influence of peer effects on the behavior of charitable giving. Based on the definitions of the reference group in this study, the estimation results suggested that peer effects on households' decisions on both whether to make charitable giving and how much to contribute were quite modest. The study also found that the price elasticity and the income elasticity of charitable giving in Taiwan were larger than those in the U.S., which may partially explain the low ratio of charitable giving to GDP in Taiwan. The earthquake in 1999 substantially increased the amount of charitable giving though its effect diminished after sometime.
