This paper examines how the trading behavior of various investors impacts the market reaction to a dividend signal. The dividend signaling model incorporates asymmetric information among traders, firm insiders, and the market. This interaction among market participants explains why not all dividend increases are viewed by the market as good news. The model predicts that the announcement day returns for a dividend increase are inversely related to measures of informed trading and decreasing in the level of buy demand relative to sell demand. Further, the model hypothesizes that more informed trading results in larger dividend increases. Empirical tests confirm these predictions.

Value maximization requires either that knowledge is transferred to those with the right to make decisions, or that decision rights are transferred to those who have the knowledge. A tradeoff of knowledge transfer costs and control costs is required. Characteristics of firms' investment opportunity sets (IOSs) that affect knowledge transfer costs and control costs are identified. Testable predictions about the relations between these characteristics and firms' decentralization decisions are developed and tested. The evidence presented is consistent with our predictions and is robust to different ways of measuring variables.
