Abstract

This talk presents conjoint, a new Stata command for analysing and visualising conjoint (factorial) experiments in Stata. Using examples of conjoint experiments from the growing literature - including two from political science involving choices between immigrants (Hainmueller et al., 2014) and between return locations for refugees (Ghosn et al., 2021) - I will briefly explain conjoint experiments and how they are used. Then, and with reference to existing packages and commands in other software, I will explain how conjoint functions to estimate and visualise the two common estimands: average marginal component effects (AMCE) and marginal means (MM). Limitations of conjoint and possible improvements to the command will also be discussed.
