We use a field experiment on energy billing in a German region to evaluate the effect of two behavioral nudges (consumption feedback and social comparison) on electricity consumption. Similar experiments have revealed significant treatment effects, yet the individual variance has proven...

We introduce a simple game-theoretical model that captures the main aspects of the repeated interaction between an issuer and a credit-rating agency. It involves up-front payments of issuer-fees and direct publication of requested ratings. Due to pecuniary injuries for untruthful ratings, the...

Recent evidence suggests that nudges, i.e. alterations in the decisional context, can have large effects on decisions and can improve individual and public welfare. This paper presents the results of a controlled experiment that was designed to evaluate not only the effectiveness of a default...

The performance of groups has been thoroughly investigated in experimental economics, showing that groups are overall more rational deciders than individuals. However, superior group performance in economic experiments has primarily been shown for face-toface decision making, which has ceased to...

The anchoring-and-adjustment heuristic has been studied in numerous experimental settings and is increasingly drawn upon to explain systematically biased decisions in economic areas as diverse as auctions, real estate pricing, sports betting and forecasting. In these cases, anchors result from...

Traditionally economic theory assumes that preferences are stable facilitating positive predictions of economic policy. While there is conflicting experimental evidence on the temporal stability of cooperation preferences in public goods provision, surprisingly little is known about their...

In this paper we experimentally test the effect of an intervention aimed at encouraging females to enter the labor market in Madagascar. We randomly assigned students in their last year of secondary education to watch a role model or a placebo video. In the role model videos, a female or a male...

This paper analyzes gender differences in access to competitive positions. We implement an experiment where workers can apply for a job promotion by sending a signal to their employer. We control for gender differences in anticipation of discrimination in a treatment where a computer randomly...

Recent evidence suggests that default based nudges i.e. alterations in the decisional context, can have large effects on decision making and can be used as policy interventions to improve individual and public welfare. This paper presents the results of a controlled experiment (N = 988),...
