We investigate the leverage of hedge funds in the time series and cross section. Hedge fund leverage is counter-cyclical to the leverage of listed financial intermediaries and decreases prior to the start of the financial crisis in mid-2007. Hedge fund leverage is lowest in early 2009 when the...

Long‐horizon investors have an edge. They can ride out short‐term fluctuations in risk premiums, profit from periods of elevated risk aversions and short‐term mispricing, and they can pursue illiquid investment opportunities. The turmoil we have seen in the capital markets over the last...

Regime switching models can match the tendency of financial markets to often change their behavior abruptly and the phenomenon that the new behavior of financial variables often persists for several periods after such a change. While the regimes identified by regime switching models are...

Traditionally, “real” assets such as inflation-indexed bonds, commodities and real estate were thought to have correlate well with inflation and thus provide protection against rising price levels. But many of these assets turn out not to be that “real.” While a single real bond provides...

Mean-variance investing is all about diversification. Diversification considers assets holistically and exploits the interaction of assets with each other, rather than viewing assets in isolation. Holding a diversified portfolio allows investors to increase expected returns while reducing risks....

The foundation for a long-term investment strategy is rebalancing to fixed asset class positions, which are determined in a one-period portfolio choice problem where the asset weights reflect the investor's attitude toward risk. Rebalancing is a counter-cyclical strategy that has worked well...

Asset owners (principals) typically do not manage their own investments and leave this job to delegated managers (agents). What is best for the asset owner, however, is usually not best for the fund manager. Additional agency conflicts arise when the asset owner does not know the quality and...

After taking into account biases induced by infrequent trading and selection, it is unlikely that illiquid asset classes have higher risk-adjusted returns than traditional liquid stock and bond markets. On the other hand, there are significant illiquidity premiums within asset classes. Portfolio...

We present a model of optimal allocation to liquid and illiquid assets, where illiquidity risk results from the restriction that an asset cannot be traded for intervals of uncertain duration. Illiquidity risk leads to increased and state-dependent risk aversion, and reduces the allocation to...
