Research
Aït-Sahalia's research has concentrated on the estimation of continuous-time models in financial economics. His primary contributions include the development of nonparametric methods for estimating and testing these models, of expansions to implement maximum-likelihood estimation of arbitrary models using discrete data, and numerous advances in the estimation and testing of models using high frequency data with a focus on understanding the role and importance of jumps.
