Quantile restrictions, revealed rankings, and the limits of multinomial choice
Tatiana Komarova
This paper analyzes when choice probabilities reveal rankings of deterministic utility indices in semiparametric discrete choice models. It begins with binary choice, where quantil…
Random Set Quantile Estimation of Partially Identified Discrete Response Models
Shakeeb Khan, Tatiana Komarova, Denis Nekipelov
Semiparametric discrete choice models are widely applied in economics, yet a fundamental tension arises when covariates are discrete as regression coefficients that are point ident…
The Anatomy of Dependence in Multivariate Ordered Choice
Tatiana Komarova, William Matcham
When individuals make simultaneous decisions across multiple ordered dimensions, standard multivariate ordered choice models impose narrow bracketing, with each dimension decided a…
Incorporating Social Welfare in Program-Evaluation and Treatment Choice
Debopam Bhattacharya, Tatiana Komarova
The econometric literature on treatment-effects typically takes functionals of outcome-distributions as `social welfare' and ignores program-impacts on unobserved utilities. We sho…
Privacy-aware identification
Tatiana Komarova, Denis Nekipelov
The paper redefines econometric identification under formal privacy constraints, particularly differential privacy (DP). Traditionally, econometrics focuses on point or partial ide…
Testing nonparametric shape restrictions
Tatiana Komarova, Javier Hidalgo
We describe and examine a test for a general class of shape constraints, such as constraints on the signs of derivatives, U-(S-)shape, symmetry, quasi-convexity, log-convexity, …
