We use a panel of more than 100,000 investor accounts in US stocks over the period 1991-95 to construct an investor-based measure of dispersion of opinion, unlike the analyst based measure used in the literature. We use this measure to test two competing hypotheses: the sidelined investors...

We study the relationship between inflation and stock returns focusing on the signalling content of inflation. Investors use inflation to learn about the stance of the monetary policy. Depending on investors’ beliefs, a change in consumption prices has different effects on the risk premium. A...

Trading generates not only information about the payoff of the assets traded, but also information about the traders themselves. Over time this information creates reputation. By using a unique dataset on the Treasury bond market we derive a measure of reputation. This is then used to group...

We focus on an exogenous event that changes the cost of capital of a company – the addition of its stock to the S&P 500 index – and investigate how companies react to it by modifying their corporate financial and investment policies. This allows us to test capital structure theories in an...

We study the effects of financial innovation in a model of endogenous information acquisition. We determine the conditions under which the introduction of a derivative written on an existing stock increases or decreases the incentive to purchase information. We show that financial innovation...

We study the impact of contractual incentives on the performance of mutual funds. We find that high-incentive contracts induce managers to take more risk and reduce the funds' probability of survival. Yet, funds with high-incentive contracts deliver higher risk-adjusted return, and the superior...

Our analysis of daily index fund flows indicates a strong contemporaneous correlation between fund inflows and S&P market returns. We also document a strong negative correlation between fund out flows and S&P market returns with the exception of outflows from a back-end load fund. These effects...

In this paper, we estimate the behavioral component of the Grinblatt and Han (2002) model and derive several testable implications about the expected relationship between the preponderance of disposition-prone investors in a market and volume, volatility and stock returns. To do this, we use a...

We investigate the way investors react to prior gains/losses. We directly examine investor reactions to different definitions of gains and losses (i.e., overall wealth, paper gains and losses, and realized capital gains and losses) and investigate how gains and losses in one category of wealth...
