Testing model specification in approximate Bayesian computation
Andrés Ramírez-Hassan, David T. Frazier
We present a procedure to diagnose model misspecification in situations where inference is performed using approximate Bayesian computation. We demonstrate theoretically, and empir…

Semi-parametric estimation of the EASI model: Welfare implications of taxes identifying clusters due to unobserved preference heterogeneity
Andrés Ramírez-Hassan, Alejandro López-Vera
We provide a novel inferential framework to estimate the exact affine Stone index (EASI) model, and analyze welfare implications due to price changes caused by taxes. Our inferenti…

Inferring hidden potentials in analytical regions: uncovering crime suspect communities in Medellín
Alejandro Puerta, Andrés Ramírez-Hassan
This paper proposes a Bayesian approach to perform inference regarding the size of hidden populations at analytical region using reported statistics. To do so, we propose a specifi…
