5.5 Estimation

• Simply compare outcome averages in treatment and control group
  • e.g., using t-tests or simple linear regression model (OLS)
• Always possible to apply further operations on the data (e.g., take subsample etc.)
• Sometimes exploring treatment heterogeneity is warranted
  • Subgroups could be affected differently
  • e.g., using novel machine learning methods (cf. Bauer and Clemm von Hohenberg 2020)
