即时通讯(Instant Messaging,IM)在网络购物中起着不可忽视的作用.本文通过对277名网络消费者进行情境模拟实验,探究了IM反馈及时性、产品类型和价格可议性三个变量对消费者态度及购买意愿的影响.结果表明:(1)IM反馈及时性对消费者态度和购买意愿具有显著正向影响:及时反馈比不反馈有更高的消费者态度和购买意愿;(2)产品类型在上述关系中有一定调节作用:体验型产品受IM反馈及时性的影响更大;(3)价格可议性并无显著调节作用.根据研究结果,从网络商家角度提出相应管理建议. 相似文献

This paper studies how communication is used by a retail gasoline cartel in Australia to coordinate price increases, a role
of communication in collusion not highlighted by Genesove and Mullin (Am Econ Rev 91(3): 379–398, 2001). A unique data set
from the trial record allows for quantifying not only the pricing dynamics, but also the communication patterns. Both empirical
and narrative evidence suggests the collusive communication and pricing behavior is well captured by the price cycle equilibrium
of the Maskin and Tirole (Econometrica 56(3): 571–599, 1988) model. 相似文献

This paper provides some new empirical findings for how French producers set prices. We used the micro data that composes
the producer and business-service price indices from 1994 to 2005. First we address how producer prices are collected. Then
we present the main characteristics of how producers change their prices: they are modified infrequently and in small amounts.
Also, a behavioural heterogeneity across sectors is observed. Business-service prices change less often than industrial producer
prices. The data corroborates both time and state-dependent model predictions. Taylor contracts are not unusual, but a firm’s
prices will also react to its economic situation. Nevertheless, the most relevant models, to explain producer price rigidity,
are time-dependent.
“The fact that some prices are rigid or sticky, while others are variable, has attracted a good deal of comments from economists in recent years” Tucker (1938)This study was conducted in the context of the Eurosystem Inflation Persistence Network. Data were processed under the responsibility of INSEE in the context of an agreement between INSEE and the Banque de France (20B-21B-E301/R05019/2005). 相似文献

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.

中国的货币政策有效吗? 总被引:4,自引:0,他引:4
本文利用1995~2008年第一季度的季度数据,建立向量自回归模型对我国货币政策的效果进行了经验分析,结果表明我国的货币政策对产出有显著的作用,并且对产出的作用主要是通过影响固定资产投资来实现的。紧缩的货币政策没能使物价水平下降,反而上涨了。与存款准备金率的变化相比,贷款利率的变动对经济的影响更大一些。因此,中央银行不能仅仅依靠紧缩的货币政策特别是频繁加息来控制物价。 相似文献

能源价格对宏观经济的影响——基于可计算一般均衡(CGE)的分析 总被引:28,自引:1,他引:28
石油与煤炭价格上涨将对中国经济造成什么样的影响,其影响度与中国现阶段的经济特点的相关性,以及如何应对能源价格上涨的影响,都是政府宏观决策需要研究的重大问题。本文运用CGE方法研究了这些问题,尤其是对石油与煤炭价格上涨影响程度的对比,填补了这一方面的研究空白。结果表明:能源价格上涨对中国经济具有紧缩作用,但对不同产业的紧缩程度不一致,能源价格除了影响经济增长,还将推动产业结构变化。对大多数产业而言,相同比例的价格上涨,煤炭的紧缩作用是石油紧缩作用的2至3倍;对于非能源密集型的服务业紧缩幅度也达3倍,石油和煤炭的经济紧缩作用程度不一致与目前中国能源消费结构基本吻合,2007年中国煤炭消费占一次能源的70%,而石油消费仅占20%。本文最后就如何应对能源价格上涨的影响提出建议。 相似文献

The literature concerning the effect of tariffs on the inter-industry wage premium has not addressed the role of total factor productivity (TFP) in determining both the wage premium and tariffs. This omission not only overlooks an important determinant of wage premium but also invalidates the use of the pre-reform tariff level as an instrument for the change in tariffs. Based on an analysis of Colombian data, I find that including TFP in the estimated model of the effects of tariffs on the wage premium leads to a 41% decrease in the effect of tariffs on the inter-industry wage premium relative to the model that omits TFP. More specifically, a 10 percentage point decrease in tariffs reduces the wage premium by 1.01%, whereas a 10% increase in TFP raise wage premium by 1.6%. This finding suggests the importance of using policies that boost productivity to offset the effect of tariffs on the wage premium. 相似文献

This paper estimates price indexes for laptop personal computers using hedonic methods and data taken from PC Magazine technical reviews. We use benchmark test results to construct a measure of system performance that encapsulates factors that have previously gone unmeasured, such as the interactions between hardware components. The resulting hedonic function is parsimonious yet has good explanatory power. A second approach to performance measurement is developed using a set of technical proxies that are shown to closely approximate the benchmark test scores, and are thus nearly perfectly equivalent in terms of resulting price index estimates. While not as parsimonious as a single performance measure, these proxies have the advantage of not requiring direct performance testing, and could thus be applied to larger data sets. Laptops were found to have declined in quality-adjusted price at an average rate of 40% per year for the period 1990-1998. 相似文献

This paper conducts an empirical analysis on the U.S. VCR market using a hedonic approach. The paper finds that quality-adjusted price indices decline at 11-12% per year, with a large annual drop of about 18% from 1982-85. Estimation and data analysis reveal interesting aspects of the evolution of quality and price in the VCR market. As a result of the exclusion of the VCR category until 1986, the paper estimates a bias of 2.4% per year in the CPI electronics subindex. 相似文献

The steady rise in the premiums charged to art buyers at auction (above hammer price) has been underway since 1992. This article, using a stable and bounded sample of repeat purchase of American works created before 1950, reveals that this tact has reduced hammer prices for that art. However, renewed and hyper-competitive efforts to bring more and higher quality art to market by the two main houses, Sotheby’s and Christie’s, have resulted in general profitability. Nevertheless, we calculate that a rise in buyers’ premia at Sotheby’s, a publically traded company, has reduced revenues and profits below their potential in the absence of such increases. 相似文献
