My research focuses on behavioral decision making and judgment, spanning the disciplines of social-cognitive psychology and economics. In particular, my work has examined the basic psychology of self-control. A cornerstone is that successful self-control requires that an individual first recognize the self-control conflict--before implementing self-control strategies. I've applied this idea to understand social interaction, such as cooperation and charitable behavior. 

In a more recent research program, I examine consumer perceptions of risk and uncertainty, relating these to household lifecycle behavior.

My research draws on a range of empirical methods, including surveys, laboratory experiments, and field studies.
