Two main approaches are commonly used to empirically evaluate linear factor pricing models: regression and SDF methods, with centred and uncentred versions of the latter. We show that unlike standard two-step or iterated GMM procedures, single-step estimators such as continuously updated GMM...

We propose new approaches to test for spanning in the return and stochastic discount factor mean-variance frontiers, which assess if either the centred or uncentred mean and cost representing portfolios are shared by the initial and extended sets of assets. We show that our proposed tests are...

Copulas offer financial risk managers a powerful tool to model the dependence between the different elements of a portfolio and are preferable to the traditional, correlation-based approach. In this paper we show the importance of selecting an accurate copula for risk management. We extend...

We propose a new approach to detecting and measuring herding which is based on the cross-sectional dispersion of the factor sensitivity of assets within a given market. This method enables us to evaluate if there is herding towards particular sectors or styles in the market including the market...

We economically motivate and then test a range of hypotheses regarding performance and risk differences between UCITS-compliant and other hedge funds. The latter exhibit more suspicious return patterns than do absolute return UCITS (ARUs), but ARUs exhibit higher levels of operational risk. We...

The dangers of shouting ``fire'' in a crowded theater are well understood, but the dangers of rushing to the exit in the financial markets are more complex. Yet, the two events share several features, and I analyze why people crowd into theaters and trades, why they run, what determines the...

We analyze the effects of the observed increased share of delegated capital for trading strategies and equilibrium prices by introducing delegation into a standard Lucas exchange economy. In equilibrium, some investors trade on their own account, but others decide to delegate trading to...

We develop a liquidity-based asset pricing model featuring investors with heterogeneous investment horizons and stochastic transaction costs. In an equilibrium where all investors invest in all assets (integration), we find that the existence of investors with heterogeneous horizons, as opposed...

Employing a new dataset of over 9,000 expressed demands for over 700 hedge funds from a secondary market for hedge funds, this paper finds evidence suggesting that hedge fund investors rationally anticipate future hedge fund performance. Both buy and sell indications of interest arrive following...

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 captured by regime switching models are identified...
