B to C交易中消费者信任的生成机理研究 总被引:1,自引:1,他引:1
张仙锋 《山西财经大学学报》2006,28(3):58-63
基于TRA、TPB和ETC等理论的扩展模型和Mcknight等人对信任的系统研究,构建出信任生成机理基础框架。同时,参考网上信任生成的周期说、因素说和DTR模型,提出由五条主线、一定的交互关系和大量影响因素组成的网上消费者信任生成机理综合模型,以期为理论研究和实践应用提供借鉴。 相似文献

4P、4C与4R:交易费用经济学的视角 总被引:1,自引:0,他引:1
宋思根 《上海市经济管理干部学院学报》2004,2(4):18-23
4P是经典营销理论的核心内容之一。随着经济、文化和技术的全球化与区域化不断发展,市场竞争异常激烈,顾客在大部分领域取得了绝对的选择权,营销理论随之出现了4C和4R等“崭新”内容。从交易费用经济学的角度看,4C和4R不是对4P的替代,而是一种重要补充和发展。 相似文献

我国电子商务的环境在不断改善,接受网上购物方式的消费者越来越多.但2001年中国B2C并没有表现出太多令人欣喜之处,甚至部分曾经领先的电子商务网站不得不面对生死存亡的抉择.造成这种现状的原因不仅仅是电子商务整体的一些原因,也包括一些影响B2C发展的特有原因.如市场发育问题、互联网的环境和条件问题、信用制度完善的问题、物流配送问题、立法问题、具体经营问题等.这些瓶颈若不能得到合理的解决,对于电子商务发展的影响将会是巨大的. 相似文献

This paper responds to the unsatisfactory argument that there is no correspondence between co-integration and the efficient market hypothesis. A law of one co-integrating vector of prices is proposed for the exchange rate and domestic and overseas stock prices. Markets must therefore be efficient in long-run equilibrium because no arbitrage opportunities exist. However, arbitrage activity via the disequilibrium error correction allows above-average (risk-adjusted) returns to be earned in the short run. The elimination of these arbitrage opportunities means that stock market inefficiency in the short run ensures stock market efficiency in the long run. 相似文献

We study market equilibration in laboratory economies that are larger and more complex than any that have been studied experimentally to date. Complexity is derived from the fact that the economies are “international” in economic structure with multiple input, output, and foreign exchange markets in operation. The economies have twenty-one markets and due to the fact that they have roughly fifty agents, the economies are characterized by several hundred equations. In spite of the complexity and interdependence of the economy, the results demonstrate the substantial power of the general equilibrium model of perfect competition to predict the direction of movement of market-level variables. Empirical patterns in the convergence process are explored and described. 相似文献

Austen-Smith and Banks [Cheap talk and burned money, J. Econ. Theory 91(1) (2000) 1-16] study how money burning can expand the set of pure cheap talk equilibria of Crawford and Sobel [Strategic information transmission, Econometrica 50(6) (1982) 1431-1451]. I identify an error in the main Theorem of Austen-Smith and Banks, and provide a variant that preserves some of the important implications. I also prove that cheap talk can be influential with money burning if and only if it can be influential without money burning. This strengthens a result of Austen-Smith and Banks, but uncovers other errors in their analysis. Finally, an open conjecture of theirs is proved correct. 相似文献

Irreversible investment and Knightian uncertainty 总被引:1,自引:0,他引:1
Kiyohiko G. Nishimura 《Journal of Economic Theory》2007,136(1):668-694
When firms make a decision about irreversible investment, they may not have complete confidence about their perceived probability measure describing future uncertainty. They may think other probability measures perturbed from the original one are also possible. Such uncertainty, characterized by not a single probability measure but a set of probability measures, is called “Knightian uncertainty.” The effect of Knightian uncertainty on the value of irreversible investment opportunity is shown to be drastically different from that of traditional uncertainty in the form of risk. Specifically, an increase in Knightian uncertainty decreases the value of investment opportunity while an increase in risk increases it. 相似文献

We use a panel data set of 59 developing countries over the 1972–1994 period to study the deforestation process. Relying on both parametric and semiparametric models, we examine nonlinearities and heterogeneity in the deforestation process. We first study the existence of an Environmental Kuznets Curve (EKC) and then analyze determinants of deforestation. Our data sample provides no evidence of an EKC. We also find that political institution failures may worsen the deforestation process in developing countries. 相似文献

Couples looking for jobs in the same labor market may cause instabilities. We determine a natural preference domain, the domain of weakly responsive preferences, that guarantees stability. Under a restricted unemployment aversion condition we show that this domain is maximal for the existence of stable matchings. We illustrate how small deviations from (weak) responsiveness, that model the wish of couples to be closer together, cause instability, even when we use a weaker stability notion that excludes myopic blocking. Our remaining results deal with various properties of the set of stable matchings for “responsive couples markets”, viz., optimality, filled positions, and manipulation. 相似文献
