We test the hypothesis that investment constraints in delegated portfolio management may distort demand for stocks, leading to price underreaction to news and stock return predictability. We find that institutions tend not to buy more of a stock with good news that they already overweight; they...

We test a new cross-sectional relation between expected stock return and idiosyncratic risk implied by the theory of costly arbitrage. If arbitrageurs find it more difficult to correct the mispricing of stocks with high idiosyncratic risk, there should be a positive (negative) relation between...

I develop an interest rate model with separate factors driving innovations in bond yields and their covariances. My model features flexible and tractable affine structure for the covariances of bond yields. Maximum likelihood estimation of the model with panel data on swaptions and discount...

We analyze capital allocation in a conglomerate where divisional managers with uncertain abilities compete for promotion to CEO. A manager can sometimes gain by unobservably adding variance to divisional output. Capital rationing can limit this distortion, increase productive efficiency, and...

Prior experimental and empirical research documents that many investors have a lower propensity to sell those stocks on which they have a capital loss. This behavioral phenomenon, known as 'the disposition effect,' has implications for equilibrium prices. We investigate the temporal pattern of...

We analyze capital allocation in a conglomerate where divisional managers with uncertain abilities compete for promotion to CEO. A manager can sometimes gain by unobservably adding variance to divisional performance. Capital rationing can limit this distortion, increase productive efficiency,...

We demonstrate that stock price momentum and earnings momentum can result from uncertainty surrounding the accuracy of cashflow forecasts. Our model has multiple information sources issuing cashflow forecasts for a stock. The investor combines these forecasts into an aggregate cashflow estimate...

This paper examines the characteristics and pricing of stocks that are actively traded by speculative retail investors. We find that stocks with high quot;retail trading proportionquot; (RTP) have strong lottery features and they attract retail investors who are known to exhibit a strong...

This paper examines whether investor sentiment about the stock market affects prices of the Samp;P 500 options. The findings reveal that the index option volatility smile is steeper (flatter) and the risk-neutral skewness of monthly index return is more (less) negative when market sentiment...
