Research Question/Issue: La Porta et al. (2000) examine the impact of corporate governance on dividend policies by testing two hypotheses, the outcome hypothesis and the substitution hypothesis. The former argues that firms with better governance may pay higher dividends to mitigate agency...

We empirically compare the reliability of the dividend (DIV) model, the residual income valuation (CT, GLS) model, and the abnormal earnings growth (OJ) model. We find that valuation estimates from the OJ model are generally more reliable than those from the other three models, because the...

We compare the equal-weight naive 1/N portfolio with mean-variance strategies from the perspective of mispricing (alpha) and provide three new findings. First, we analytically show that the 1/N rule approaches the ex ante mean-variance efficient portfolio in the absence of mispricing. With...

We derive a closed-form appraisal/information ratio of the investors who are able to observe some information about security fundamentals, by solving a simple instantaneous mean-variance portfolio choice problem in a continuous-time framework. Both analytical and numerical results suggest that...

We examine the problem of an investor who trades in a market with unobservable regime shifts. The investor learns from past prices and is subject to transaction costs. Our model generates significantly larger liquidity premia compared to a benchmark model with observable market shifts. The...

We generate large liquidity premia endogenously from the interaction of transaction costs with convexity in preferences, offering a novel explanation for a longstanding puzzle. We derive this result from the dynamic portfolio problem of mutual fund managers facing either convex flows or year-end...
