This paper introduces the concept of statistical arbitrage, a long horizon trading opportunity that generates a riskless profit and is designed to exploit persistent anomalies. Statistical arbitrage circumvents the quot;joint hypothesisquot; dilemma of traditional market efficiency tests because...

We evaluate the relative performance of funds by conditioning their returns on the cross-section of portfolio characteristics across fund managers. Our implied procedure circumvents the need to specify benchmark returns or peer funds. Instead, fund-specific benchmarks for measuring selection and...

Statistical arbitrage enables tests of market efficiency which circumvent the joint-hypotheses dilemma. This paper makes several contributions to the statistical arbitrage framework. First, we enlarge the set of statistical arbitrage opportunities in Hogan, Jarrow, Teo, and Warachka (2004) to...

A quantum field theory generalization, Baaquie, of the Heath, Jarrow, and Morton (HJM) term structure model parsimoniously describes the evolution of imperfectly correlated forward rates. Field theory also offers powerful computational tools to compute path integrals which naturally arise from...

This paper implements the Asymmetric Autoregressive Conditional Duration (AACD) model of Bauwens and Giot (2003) to analyze irregularly spaced transaction data of trade direction, namely buy versus sell orders. We examine the influence of lagged transaction duration, lagged volume and lagged...

Tobin's q is often used to proxy for firm performance when studying the relation between corporate governance and firm performance. However, our theoretical and empirical analysis demonstrate that Tobin's q does not measure firm performance since underinvestment increases rather than decreases...

We test a frog-in-the-pan (FIP) hypothesis that predicts investors are inattentive to information arriving continuously in small amounts. Intuitively, we hypothesize that a series of frequent gradual changes attracts less attention than infrequent dramatic changes. Consistent with the FIP...

We develop and test a frog-in-the-pan hypothesis that predicts investors are less attentive to information arriving continuously in small amounts than to information with the same cumulative stock price implications arriving in large amounts at discrete timepoints. Intuitively, we hypothesize...

State governments receive an exogenous tax windfall whenever their residents win a multi-state lottery. These lottery tax windfalls are counter-cyclical but occur during a range of economic conditions. Therefore, lottery tax windfalls enable us to estimate the impact of fiscal policy on...

Informal risk sharing within social networks and formal financial contracts both enable households to manage risk. We find that financial contracting reduces participation in social networks. Specifically, increased crop insurance usage decreased local religious adherence and congregation...
