Mira Fischer

Welcome to my personal website.


I am a postdoc in economics at the University of Cologne and will be a research associate at WZB Berlin from September 2018. I am also a research affiliate at IZA.

My research interests are in education, labor markets, organizations, and public policy. I use lab and field experiments as well as analysis of survey and administrative data to study institutional determinants of changes in people's beliefs and behavior, and how these affect individual and social outcomes.

JOB-MARKET PAPER: Effects of Timing and Reference Frame of Feedback: Evidence from a Field Experiment in Secondary Schools, with Valentin Wagner
Information about past performance has been found to sometimes improve and sometimes worsen subsequent performance. We hypothesize that two factors may help to explain this puzzle: which aspect of one's past performance the information refers to and when it is revealed. In a field experiment, students received information about their absolute rank in the last math exam (level feedback), their change in ranks between the second last and the last math exam (change feedback), or no feedback. Feedback was given either 1-3 days (early) or immediately (late) before the final math exam of the semester. Both level feedback and change feedback significantly improve students' grades in the final exam when given early and tend to worsen them when given late. The largest effects are found for negative change feedback and are concentrated on male students, who adjust their ability beliefs downwards in response to feedback.

Salience of Ability Grouping and Biased Belief Formation
Recent research in economics has found that a higher ordinal rank within one's class affects subsequent skill acquisition positively and has linked this finding to the “big-fish-little-pond-effect”, a popular proposition in psychology claiming that assignment to a peer group with lower skills increases one's confidence in academic ability. Findings from a lab experiment suggest that salience of the group assignment mechanism matters for how ability grouping affects ability beliefs. If the assignment mechanism is non-salient, it does not matter for subjects' confidence whether they are assigned to the weaker or the stronger group, however, when the group assignment mechanism is salient, weaker group assignment makes people less confident. Subjects are on average less confident when the group assignment mechanism is salient than when it is non-salient. This is found to be the case due to weaker group assignment making people more underconfident than stronger group assignment making people overconfident, indicating that people overweigh negative information as compared to positive information. These findings may help to understand the effects of ability grouping in the field and may inform the design of educational and workplace environments.
