Economic models typically allow for “free disposal” or “reversibility” of information, which implies non-negative value. Building
on previous research on the “curse of knowledge” we explore situations where this might not be so. In three experiments, we
document situations in which participants place positive value on information in attempting to predict the performance of
uninformed others, even when acquiring that information diminishes their earnings. In the first experiment, a majority of
participants choose to hire informed—rather than uninformed—agents, leading to lower earnings. In the second experiment, a
significant number of participants pay for information—the solution to a puzzle—that hurts their ability to predict how many
others will solve the puzzle. In the third experiment, we find that the effect is reduced with experience and feedback on
the actual performance to be predicted. We discuss implications of our results for the role of information and informed decision
making in economic situations.

Summary. We consider an environment where individuals sequentially choose among several actions. The payoff to an individual depends on her action choice, the state of the world, and an idiosyncratic, privately observed preference shock. Under weak conditions, as the number of individuals increases, the sequence of choices always reveals the state of the world. This contrasts with the familiar result for pure common-value environments where the state is never learned, resulting in herds or informational cascades. The medium run dynamics to convergence can be very complex and non-monotone: posterior beliefs may be concentrated on a wrong state for a long time, shifting suddenly to the correct state.Received: 6 January 2005, Revised: 5 May 2005, JEL Classification Numbers:

This paper uses the experimental method to investigate behavior in a coordination game when the information available to subjects
is limited to their feasible choices and their experienced payoffs. In the experiment subjects converge to an absorbing state
at rates that are orders of magnitude faster than reinforcement learning algorithms, but slower than under complete information.
This state is very close to a mutual best response outcome. All cohorts converged to the market statistic predicted by the
interior equilibrium regardless of the information conditions or the stability conditions.

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures
to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this
wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing
and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are
informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation
in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None
> All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on
information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected
utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result
contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed.
The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify
analytical welfare predictions of expected utility under different policy choices.

公司治理结构与会计信息都产生于委托代理理论、契约理论和产权理论的需要,理论基础的交叉重叠使会计信息与公司治理结构具有内在的逻辑性。会计信息质量决定公司治理效率,目前由于会计信息的有效需求不足和供给质量不高导致信息供需不均衡,从而使会计信息与公司治理陷入恶性循环,本文通过剖析信息供需机制不均衡的原因,提出完善的对策和建议。 相似文献

信息不对称资本市场的实验研究 总被引:17,自引:0,他引:17
我们采用经济学实验研究方法构建了信息不对称的实验室资本市场,研究信息是否可以通过市场迅速传递。实验结果表明,在信息不对称的情况下,资本市场是非有效的;市场对信息的传递和价格反应是有条件的而且也是需要时间的;资本市场中的投资者并非完全理性,而是具有认知和行为偏差的普通人,存在过度自信和过度交易的情况;信息不对称还可能引起市场操纵行为,从而导致价格泡沫的形成。 相似文献
