Factor investing asks: how well can a particular investor weather hard times relative to the average investor? Answering helps her reap long-run factor premiums by embracing risks that lose money during bad times, but make up for it the rest of the time with attractive rewards. When factor...

About once a quarter. We compute optimal tactical asset allocation (TAA) policies over equities and bonds when both asset returns are predictable. By varying how often the weights are reset, we estimate the benefits and costs of different frequencies of TAA decisions. Tactical tilts taking...

American university and college endowments now hold close to one-third of their portfolios in private equity and hedge funds. We estimate the implied beliefs of endowments about alternative assets' returns relative to equities and bonds. At the end of 2012, the typical endowment believes that...
