This article documents the “bad habits” of investors in asset allocation practices. Whereas financial markets exhibit momentum over multi-month horizons but more reversion to the mean over multi-year horizons, many investors act like momentum investors even at these longer horizons. Both...

Using a lifecycle framework with Epstein-Zin (1989) utility and a mixed-integer optimization approach, we compute the optimal age to claim Social Security benefits. Taking advantage of homogeneity, a sufficient statistic is the ratio of wealth to the primary insurance amount (PIA). If the...

We seek to develop a model of optimal asset allocation with a market that has the potential to decouple. There are three Markov regimes: a regime where the market remains fully investable, a second regime where the market may become potentially decouple, and a third regime where the market...

Traditional quantitative approaches to portfolio construction have drawbacks for investors or advisors who combine multiple active managers in typically producing large numbers of disperse positions. We develop a new methodology for sequentially allocating to active funds that results in...

We develop a liability driven investment framework that incorporates downside risk penalties for not meeting liabilities. The shortfall between the asset and liabilities can be valued as an option which swaps the value of the endogenously determined optimal portfolio for the value of the...
