Hedge funds often impose lockups and notice periods to limit the ability of investors to withdraw capital. We model the investor's decision to withdraw capital as a real option and treat lockups and notice periods as exercise restrictions. Our methodology incorporates time-varying probabilities...

We exploit these different market conditions to test theories of cross-sectional return premiums. Compared to premiums in listed markets, the OTC illiquidity...
