We construct a zero-net-worth uninformed "naive investor" who uses a random portfolio allocation strategy. We then compare the returns of the momentum strategist to the return distribution of naive investors. For this purpose we reward momentum profits relative to the return percentiles of the...

We propose a portfolio optimization approach to identifying private information. In our model, investors are exposed to liquidity and private information shocks and optimize their trading across stocks taking into account price impact (Kyle's Lambda). We obtain a very simple expression for a...

Banks produce short-term debt for transactions and storing value. The value of bank money must not vary over time so agents can easily trade this debt at par. This requires that no agent finds it profitable to produce costly private information about the bank's loans. To produce safe liquidity...

We develop a two-period general equilibrium model of portfolio delegation with competitive, differentially skilled managers and convex compensation contracts. We show that convex incentives lead to significant equilibrium mispricing, but reduce price volatility. In particular, price...

I study a generalized OLG economy where asymmetrically informed agents have arbitrary investment horizons. As horizons increase, the age-adjusted risk aversion of investors fall, and the risk transfer from forced liquidators into voluntary buyers drops. Two equilibria coexist for long enough...

This paper employs a proprietary data set of portfolio transitions to analyze the short run price-volume relation and its association with the long run performance of newly hired and terminated managers. Unique to our study is its focus on price dynamics that is not affected by potential...

This paper investigates prices and endogenous research decision for financial assets. In rational expectations models with public information, higher order beliefs make investors to overweight the public information relative to underlying fundamentals. The extent of this mispricing is higher if...

We develop a dynamic model of banks whose insiders have superior information about the impact of a pending shock to the bank’s cash holdings and can signal the bank’s type through its dividend policy. Banks that will be adversely affected by the shock have incentives to pool with unaffected...

While most accounting information is idiosyncratic in nature, economy-wide factors such as accounting standards affect the quality of idiosyncratic accounting information of many firms simultaneously. We study idiosyncratic and systematic features of accounting information by embedding a...

Asymmetric shocks are common in markets; securities'; payoffs are not normally distributed and exhibit skewness. This paper studies the portfolio holdings of heterogeneous agents with preferences over mean, variance and skewness, and derives equilibrium prices. A three funds separation theorem...
