INSIGHT

Why Structural Models Are Worth The Assumptions

  • Structural I.O. tackles important but hard-to-identify questions by imposing economic structure to extract private information like marginal costs.
  • Researchers accept model assumptions when the question's importance justifies them and robustness is checked.
ANECDOTE

Bayes Through Community And Collaboration

  • Shosh learned Bayesian methods through friends in grad school, notably Rachel Meager and Jim Savage, and by joining the Stan community.
  • That network led to collaborative Bayesian projects on random-coefficient logit models.
ADVICE

Estimate Risk And Choice Jointly

  • Model selection and behavior jointly when choices and risk interact; estimate the statistical risk model and the choice model together.
  • Use hierarchical Bayesian models to capture individual heterogeneity and share strength across people.
