This doctoral thesis aims to contribute to the literature on hedge fund performance in three interrelated essays. The first essay uses a novel database aggregation and a comprehensive analysis of differences between the main commercial databases exploring the effects of different databases on previously documented stylized facts, including the (1) average risk-adjusted performance; (2) the persistence of that performance; (3) and the cross-sectional relation between fund-characteristics and risk-adjusted returns. The main finding is that several previously documented stylized facts about hedge fund performance are sensitive to database selection and associated biases. Differences in conclusions stem from database differences in defunct coverage, survivorship and backfill biases, and the completeness of assets under management information. The second essay examines the effect of frictions on the returns that investors can earn from investing in hedge funds. The study focuses on size and redemption restrictions that are key investment constraints in practice. The size–performance relationship is positive (negative) when past (future) performance is used. The negative size–performance relationship is consistent with theories suggesting a decreasing returns-to-scale in the active management industry. Differences in attrition rates and risk taking as well as the relative importance of management fees and capacity constraints between small and large funds are consistent with an equilibrium in which investors and hedge funds optimally respond to incentives subject to constraints. Performance persistence decreases along with the fund size but concentrated hypothetical Fund-of-Fund portfolios outperform. The third essay examines hedge funds' ability to enhance their performance through leverage. The essay explicitly shows that leverage enhances risk-adjusted performance and risk of investment programs. The main finding is that the average high-leverage fund class underperforms its low-leverage counterpart of the same investment program after their returns are appropriately adjusted to the same level. The finding is consistent with the predictions of leverage aversion theories suggesting that leverage constraints and costs of leverage have a negative impact on riskadjusted returns.
