Erin L. Krupka is an assistant professor at the University of Michigan School of Information. She received her B.A. from Wheaton College in 1997 and her Masters in Public Policy from the University of Chicago in 2000. In 2007 she completed her Ph.D. in Behavioral Decision Research at Carnegie Mellon University in Pittsburgh, PA. In her research she explores how social and environmental factors influence behavior using both laboratory and field experiments. Her current research focuses primarily on two areas: social norms and inter-temporal choice. Her research on social norms suggests why individuals might engage in behaviors which appear inconsistent with self-interest and suggests why trivial modifications to a decision context can change behavior significantly. Her research on inter-temporal choice suggests that elicited impatience estimates are sensitive to environmental factors which, in turn, may have implications for high interest credit use among financially vulnerable populations.

She joined IZA as a Research Associate in July 2007. After leaving for Michigan, she became a Research Fellow in September 2009.

This paper presents the results of a field study at a large financial services firm that combines multiple methods, including two economic experiments, to measure ethical norms and their behavioral correlates. Standard survey questions eliciting ethical evaluations of actions in on-the-job ethical dilemmas are transformed into a series of incentivized...

We explore the influence of social norms on behavior. To do so, we introduce a method for identifying norms, based on the property that social norms reflect social consensus regarding the appropriateness of different possible behaviors. We demonstrate that the norms we elicit, along with a simple model combining concern...

This paper reports an experiment examining the effect of social norms on pro-social behavior. We test two predictions derived from work in psychology regarding the influence of norms. The first is a “focusing” influence, whereby norms only impact behavior when an individual’s attention is drawn to them; and the second...
