This paper investigates how a profit-maximizing asset originator can coordinate the information acquisition of investors with different expertise by means of asset bundling. Bundling is beneficial to the originator when it discourages investors from analyzing idiosyncratic risks and focuses...

We consider a privately informed issuer which holds a portfolio of assets that can be sold to raise cash, where the fractions of assets sold serve as a multidimensional signal. If good news about one asset is good news for the others, then there is a unique equilibrium that satisfies the...

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...

When a long-term investor trades a slowly changing portfolio, she is not very time sensitive to when she should place or modify her bet. Short-term information can be used to guide the investor on how to time her trades. Strategic trade modification provides exposure to short-term signals...

In this paper, we analyze the conflicts of interest of an informed agent who is responsible for divulging his private information about a company and has a reward function positively dependent on its stock price. We assume that the demand for the stock is subject to shocks that may increase...

By allowing for imperfectly informed markets and the role of private information, we offer new insights about observed deviations of portfolio concentrations in domestic relative to foreign risky assets, or "home bias", from what standard finance models predict. Our model ascribes the "bias" to...

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...

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...
