Information markets are low volume markets whose prices offer informative estimates on particular policy topics of interest. Observers have expressed concern that such prices might be less informative due to manipulators, i.e., traders who prefer that we see some policy estimates instead of others. We adapt a Kyle-style market microstructure model to the case of information markets, by assuming...

This paper studies herding behavior of institutional investors in international markets. First, we document the existence of wide-spread herding in 41 countries (referred to as ‘‘target countries’’ hereafter) in the sample. We then examine the relation between contemporaneous institutional demand and future returns and find that institutional herding stabilizes prices. Next, we examine the rela...

This article presents an economic model of a monopoly retailer with supply and demand uncertainties that enables the study of incentives for B2B e-procurement technology investments that permit inventory coordination and operating cost control. In this context, we focus on the information technology (IT) adoption behavior of firms, emphasizing the trade-offs they make between managing supply pr...

Trust is particularly important in online markets to facilitate the transfer of sensitive consumer information to online retailers. In electronic markets, various proposals have been made to facilitate these information transfers. We develop analytic models of hidden information to analyze the effectiveness of these regimes to build trust and their efficiency in terms of social welfare. We find...
