EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

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.

网络口碑信息对消费者购买决策的影响：一个实验研究

本文通过实验法考察了网络口碑信息对消费者购买决策的影响，就网络口碑的影响力在口碑信息类型、传播方向和产品涉入度不同的情况下会表现出哪些差异等问题作了分析。实验结果支持了所提出的6项假设，网络口碑信息对于消费者购买决策的影响力可能会随着口碑传播方向、信息类型以及产品卷入度的不同而呈现出显著差异的预测得到了证实；信息类型、传播方向和产品卷入度之间所存在的交互效应也会明显地作用到网络口碑对消费者购买决策的影响效果。

E-Finance: An Introduction

E-finance is defined as “The provision of financial services and markets using electronic communication and computation”. In this paper we outline research issues related to e-finance that we believe set the stage for further work in this field. Three areas are focused on. These are the use of electronic payments systems, the operations of financial services firms and the operation of financial markets. A number of research issues are raised. For example, is the widespread use of paper-based checks efficient? Will the financial services industry be fundamentally changed by the advent of the Internet? Why have there been such large differences in changes to market microstructure across different financial markets?
