Self-Correcting Information Cascades 总被引:2,自引:0,他引:2
JACOB K. GOEREE THOMAS R. PALFREY BRIAN W. ROGERS RICHARD D. McKELVEY 《The Review of economic studies》2007,74(3):733-762
We report experimental results from long sequences of decisions in environments that are theoretically prone to severe information cascades. Observed behaviour is much different—information cascades are ephemeral. We study the implications of a theoretical model based on quantal response equilibrium, in which the observed cascade formation/collapse/formation cycles arise as equilibrium phenomena. Consecutive cascades may reverse states, and usually such a reversal is self-correcting: the cascade switches to the correct state. These implications are supported by the data. We extend the model to allow for base rate neglect and find strong evidence for overweighting of private information. The estimated belief trajectories indicate fast and efficient learning dynamics. 相似文献

Without an evaluation of the costs and benefits arising from the production of standards for consumer goods, consumer policy makers will be operating with incomplete information in their decision-making. A standard specification for a fabric used in upholstered furniture is costed to see what resources were used in its preparation and what benefits can be estimated to have accrued to the consumer. 相似文献

This paper examines changes in families' finances as captured in the 2007–2009 Survey of Consumer Finances panel. The broad contours of changes in families' assets, debts, and wealth align with changes in the corresponding aggregate measures, but the microdata from the panel highlight substantial variation in families' experiences between 2007 and 2009. Although more than 60% of families saw their wealth decline over the two‐year period, a sizable fraction experienced gains in wealth, while some families' financial situations saw little change on net. The shifts in wealth do not appear to be correlated in a simple way with families' characteristics. Instead, the patterns of mixed losses, gains, and modest shifts in wealth generally hold within groups defined by demographic characteristics or by 2007 wealth or income. On the whole, changes in wealth appear to stem from changes in asset values rather than from changes in portfolio composition or debt levels. 相似文献

Exploring the simultaneous effects of key variables on the unhealthy consumption behavior of adolescents, two studies focused on the relative effects of advertising, parental and peer influence, and self-efficacy on adolescent tobacco use and alcohol consumption. The results suggest that (1) advertising effects are largely neutralized by parental and peer influence; (2) peer and parental influence strongly predict adolescent tobacco use and alcohol consumption; and (3) self-efficacy is a weak predictor of both adolescent risk behaviors. 相似文献

This paper presents an adverse selection model in which progressive taxation enhances productive efficiency by encouraging a principal (buyer) to be less aggressive in contracting with an agent (seller). Wary of padded cost budgets, the buyer employs a hurdle‐rate procurement policy. With a low cost hurdle, the buyer keeps greater profits when transactions are undertaken but trade occurs less often. While the hurdle is unaffected by a flat tax, a progressive tax tilts the buyer's preference: the buyer's benefit from a lower hurdle becomes less pronounced, since the marginal increase in his profits is muted in after‐tax terms. The result is increased trade and the possibility of Pareto improvements. 相似文献

The practice of removing item prices in scanner-equipped grocery stores has raised an important public policy issue relating to the ability of individual consumers to engage in effective shopping with less available price information at the point of purchase. This study investigated the likely impact of item price removal in scanner-equipped grocery stores as a function of consumers' use of price information, general consumer predispositions, and consumers' experience with scanner technology. Particular emphasis was placed on the likely effects of item price removal on disadvantaged consumers. The implications of the study for public policy are discussed. 相似文献

Financial statements summarize a firm's fiscal position using only a limited number of accounts. Readers often interpret financial statements in conjunction with other information, some of which may be aggregated in a different way (or not at all). This paper exploits properties of the double‐entry accounting system to provide a systematic approach to reconciling diverse financial data. The key is the ability to represent the double‐entry system by network flows and, thereby, access well‐recognized network optimization techniques. Two specific uses are investigated: the reconciliation of audit evidence with management‐prepared financial statements, and the creation of transaction‐level financial ratios. 相似文献

Economic Determinants and Information Environment Effects of Earnouts: New Insights from SFAS 141(R)
Contingent considerations (earnouts) in acquisition agreements provide sellers with future payments conditional on meeting certain conditions. Prior research provides evidence that acquiring firms use earnouts to minimize agency costs associated with acquisitions. Using earnout fair value information, recently mandated by SFAS 141(R), we provide new insights into the economic determinants to include earnout provisions in acquisition agreements, including motivations to resolve moral hazard and adverse selection problems, bridge valuation gaps, and retain target firm managers. We document variations in initial earnout fair value estimates and earnout fair value adjustments that correspond with these underlying motivations. We also provide evidence that target managers stay longer with the firm after the acquisition when earnouts are included primarily to retain target managers. Finally, we demonstrate that earnout fair value adjustments required by SFAS 141(R) provide valuable information to market participants and are negatively associated with the likelihood of contemporaneous and future goodwill impairments. 相似文献

Abstract. This article compares the properties of several common liquidity measures including the bid-ask spread, the liquidity ratio and firm size. We also use the proportional hazard model to develop a new measure, the relative odds ratio, based on the volume necessary to move prices by a predetermined amount. Although each measure displays a liquidity premium, a composite measure better explaims expected returns, suggesting that liquidity is a multidimensional phenomenon. 相似文献
