Aggregate demand by insiders predicts time-series variation in the value premium — between 1978 and 2004, a one standard deviation increase in aggregate insider demand in the previous six months forecasts a 53 basis point decline (6.54% annualized) in the expected value premium in the month...

In this paper, we analyze the conflicts of interest of an informed agent who is responsible for divulging his private information about a company and has a reward function positively dependent on its stock price. We assume that the demand for the stock is subject to shocks that may increase...

We examine the relation between the investment horizons of insiders and the information content of their trading activity regarding future stock returns. We conjecture that an insider's investment horizon establishes a benchmark for expected patterns of continued trading behavior, and thus helps...

We study whether industry familiarity is an advantage in stock trading by exploring the trading patterns of industry insiders in their own personal portfolios. To do so, we identify accounts of industry insiders in a large dataset provided by a retail discount broker. We find that insiders trade...

Using holdings-based performance measures, we test whether Norway's doubling of its female director network (through board gender-balancing) has increased female insider trading performance. We find that the gender-based insider performance has remained statistically indistinguishable from zero....

Some individuals, e.g., those holding multiple directorships, are insiders at multiple firms. When they execute an insider trade at one firm, they may reveal information about the value of all—both the traded insider position and not-traded insider position(s)—the securities held in their...

The paper proposes a model of delegated portfolio management in which career concerns lead to unprofitable trade by uninformed managers (i.e. churning). We find that churning does not necessarily reduce the return that a representative investor expects ex-ante from delegating trade to a manager....

We study banks' incentive to pool assets of heterogeneous quality when investors evaluate pools by extrapolating from limited sampling. Pooling assets of heterogeneous quality induces dispersion in investors' valuations without affecting their average. Prices are determined by market clearing...

A rational-expectations equilibrium with positive demand for financial information does exist under fully revealing asset price - contrary to a wide-held conjecture. Generalizing the common additive signal-return model with CARA utility to the family of distributions with moment generating...

The paper examines the tendency to sell winners and hold on to losers in a dynamic noisy rational expectations equilibrium with informed and uninformed investors. The key feature of the model is that the information asymmetry between investors varies over time. Besides demonstrating that the...
