We model how investors allocate between asset managers, managers choose their portfolios of multiple securities, fees are set, and security prices are determined. The optimal passive portfolio is linked to the “expected market portfolio,” while the optimal active portfolio has elements of...

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...
