This paper reviews recent developments in nonparametric identication of measurement error models and their applications in applied microeconomics, in particular, in empirical industrial organization and labor economics. Measurement error models describe mappings from a latent distribution to an observed distribution. The identication and estimation of measurement error models focus on how to obtain the latent distribution and the measurement error distribution from the observed distribution. Such a framework is suitable for many microeconomic models with latent variables, such as models with unobserved heterogeneity or unobserved state variables and panel data models with xed eects. Recent developments in measurement error models allow very exible specication of the latent distribution and the measurement error distribution. These developments greatly broaden economic applications of measurement error models. This paper provides an accessible introduction of these technical results to empirical researchers so as to expand applications of measurement error models. Speaker’s research fields include: Econometrics, Empirical Industrial Organization, Labor Economics, Microeconomic models with latent variables, Measurement error models.
