This paper studies static rational inattention problems with multiple actions and multiple shocks. We solve for the optimal signals chosen by agents and provide tools to interpret information processing. By relaxing restrictive assumptions previously used to gain tractability, we allow agents...

We consider competition among n sellers when each of them sells a portfolio of distinct products to a buyer having limited slots (or shelf space). We study how bundling affects competition for slots. When the buyer has k number of slots, efficiency requires the slots to be allocated to the best...

In this study, we employ a statistical arbitrage approach to demonstrate that momentum investment strategy tend to work better in periods longer than six months, a result different from findings in past literature. Compared with standard parametric tests, the statistical arbitrage method...

This paper characterizes how firms' strategic interaction in product markets affects the industry dynamics of investment and expected returns. In imperfectly competitive industries, a firm's exposure to systematic risk is jointly affected by its own investment strategy and the investment...

Product scope adjustment is a key mechanism through which multi-product firms achieve efficient resource allocations. In this paper, we take a novel perspective to study firms' product scope adjustment behavior through the lens of asset pricing. Using a unique panel scanner data set containing...

We examine how investor demand for leverage shapes asset management fees. In our model, investors' leverage demand generates a cross-section of positive fees even if all managers produce zero risk-adjusted returns. We find support for the model's novel predictions in the sample of the U.S....
