The existing replication policies at top finance journals are far weaker than the policies at top economics journals. This paper explores both the costs and benefits of having a stronger replication policy in the context of my failed 2010 initiative to develop a unified policy across all top...

We administer psychometric tests to senior executives to obtain evidence on their underlying psychological traits and attitudes. We find US CEOs differ significantly from non-US CEOs in terms of their underlying attitudes. In addition, we find that CEOs are significantly more optimistic and...

We use a unique data set that contains information on more than 1,000 Chief Executive Officers (CEOs) and Chief Financial Officers (CFOs) around the world to investigate the degree to which executives delegate financial decisions and the circumstances that drive variation in delegation....

We administer psychometric tests to senior executives to obtain evidence on their underlying psychological traits and attitudes. We find U.S. CEOs differ significantly from non-U.S. CEOs in terms of their underlying attitudes. In addition, we find that CEOs are significantly more optimistic and...

We recently conducted a comprehensive survey that analyzes how senior financial executives make decisions related to performance measurement and voluntary disclosure. In particular, we ask CFOs what earnings benchmarks they care about and which factors motivate executives to exercise discretion,...

When evaluating a trading strategy, it is routine to discount the Sharpe ratio from a historical backtest. The reason is simple: there is inevitable data mining by both the researcher and by other researchers in the past. Our paper provides a statistical framework that systematically accounts...

Why do firms manage risk? According to theory, firms hedge to mitigate credit rationing, to alleviate information asymmetry, and to reduce the risk of financial distress. Empirical support for these theories is mixed. Our paper addresses the “why” by directly questioning the managers that...
