In this paper we examine how the information processing of subjects who make an innovative choice (innovators) differs from that of subjects who make a noninnovative choice (noninnovators). The task involves selection of an alternative within a range of prerated product category innovativeness. We propose that subjects who seek 1) impersonal/uncontrollable sources, 2) higher levels of information, 3) more detailed (versus summary) data, and 4) noncomparative (versus comparative) data are more likely to make innovative choices. The research method is a computerized process tracing experiment utilizing Search Monitor (Brucks 1988).The authors wish to express their gratitude to Merrie Brucks for the use of and help with Search Monitor and to Eric Johnson, Dave Schmittlein, and Mita Sujan for helpful comments on an earlier version of this paper. 相似文献

Summary. We analyze an infinite horizon model where a seller who owns an indivisible unit of a good for sale has incomplete information
about the state of the world that determines not only the demand she faces but also her own valuation for the good. Over time,
she randomly meets potential buyers who may have incentives to manipulate her learning process strategically. We show that
i) the seller's incentives to post a high price and to experiment are not necessarily monotonic in the information conveyed
by a buyer's rejection; and ii) as the discount factors tend to one, there are equilibria where the seller always ends up
selling the good at an ex-post individually rational price.

Punishment,counterpunishment and sanction enforcement in a social dilemma experiment 总被引:1,自引:0,他引:1
We present the results of an experiment that explores the sanctioning behavior of individuals who experience a social dilemma.
In the game we study, players choose contribution levels to a public good and subsequently have multiple opportunities to
reduce the earnings of the other members of the group. The treatments vary in terms of individuals’ opportunities to (a) avenge
sanctions that have been directed toward themselves, and (b) punish others’ sanctioning behavior with respect to third parties.
We find that individuals do avenge sanctions they have received, and this serves to decrease contribution levels. They also
punish those who fail to sanction third parties, but the resulting increase in contributions is smaller than the decrease
the avenging of sanctions induces. When there are five rounds of unrestricted sanctioning, contributions and welfare are significantly
lower than when only one round of sanctioning opportunities exists, and welfare is lower than at a benchmark of zero cooperation.

资本市场变迁及运行效率是中外学者研究的重点,形成了许多理论流派,其中信息空间理论为资本市场制度变迁提供了新的分析框架。同时,中国资本市场正处在发展建设之中,亟需有效的理论指导其发展。然而,中国资本市场的不完备性和特殊性导致诸多理论的应用存在局限性。而信息是各理论流派研究的核心,只是角度和侧重点不同,故信息空间理论可为研究资本市场变迁和制度选择提供新的研究思路。 相似文献

Auditing is modeled in a sequential game without commitment. The manager must decide whether and where to audit a worker's output, taking into account all interim information he has obtained. The worker will work just hard enough (and show it) to divert the manager from making an audit or cover up, withholding information about his work to make an audit more difficult. This usually raises the costs of setting work incentives, so incentives are softened, sometimes drastically. Moreover, when a worker's on-the-job information is valuable for entrepreneurial decisions, work incentives must be softened to improve the internal flow of information. 相似文献

信用风险控制既是风险控制研究的理论难点,也是风险控制实践的难点。从非对称信息理论的角度出发。分析非对称信息下信用风险形成的机理,可以得出控制信用风险的关键在于事前阶段的结论。加强客户信用信息管理系统的建设是企业降低信用风险的关键,也是实现企业信用风险标本兼治的第一步。 相似文献
