Mean-variance criteria remain prevalent in multi-period problems, and yet not much is known about their dynamically optimal policies. We provide a fully analytical characterization of the optimal dynamic mean-variance portfolios within a general incomplete-market economy, and recover a simple...

This article analyzes the dynamic portfolio choice implications of strategic interaction among money managers. The strategic interaction is modelled as managers' having relative performance concerns in their objectives, either due to money flows or behavioral considerations. We provide tractable...

This article studies an economy with borrowers (firms or individuals) under costly default. Borrowers defaulting under adverse economic conditions may, despite incurring default costs, emerge as wealthier than nonborrowers. Asset substitution is generally not pronounced, although a larger risk...

This article analyzes optimal, dynamic portfolio and wealth/consumption policies of utility maximizing investors who must also manage market-risk exposure using Value-at-Risk (VaR). We find that VaR risk managers often optimally choose a larger exposure to risky assets than non risk managers,...

This article analyzes the dynamic portfolio choice implications of strategic interaction among money managers, arising as they compete for fund flows. We study such interaction between two risk-averse managers in continuous time, characterizing analytically their unique equilibrium investments....

Despite much work on hedging in incomplete markets, the literature still lacks tractable dynamic hedges in plausible environments. In this article, we provide a simple solution to this problem in a general incomplete-market economy in which a hedger, guided by the traditional minimum-variance...

Existing studies of household stock trading using administrative data offer conflicting results: discount brokerage accounts exhibit excessive trading, while retirement accounts show inactivity. This paper uses population-wide data from PSID and SCF to examine the overall extent of household...

Money managers are rewarded for increasing the value of assets under management. This gives a manager an implicit incentive to exploit the well-documented positive fund-flows to relative-performance relationship by manipulating her risk exposure. The misaligned incentives create potentially...
