Session 2_ Lecture 2_ Studying Discrimination: Field Experiments  
Session description 
In this session we will explain the logic of field experimental research on discrimination with special attention to the crucial role of randomization for causal identification. We will review basic concepts (control group, treated group, experimental units, etc…) and different types of experiments (audit studies, correspondence  studies) and designs (paired/unpaired, fractional, factorial, etc). The lecture will be followed by a discussion of two highly-cited papers on racial discrimination in hiring, Bertrand and Mullainathan (2004) and Pager (2007), which will be presented and discussed by students.
