We present an econometric method for estimating the parameters of a diffusion model from discretely sampled data. The estimator is transparent, adaptive, and inherits the asymptotic properties of the generally unattainable maximum likelihood estimator. We use this method to estimate a new...

Investors rebalance their portfolios as their views about expected returns and risk change. We use empirical measures of portfolio rebalancing to back out investors' views, specifically their views about the state of the economy. We show that aggregate portfolio rebalancing across equity sectors...

We present a simple 2-factor model that helps explaining several capital asset pricing model (CAPM) anomalies (value premium, return reversal, equity duration, asset growth, and inventory growth). The model is consistent with Merton's intertemporal CAPM (ICAPM) framework and the key risk factor...
