Econometrics I, Mathematics

This is a graduate course on Econometrics. The first part of the course discusses inferences on linear models under standard conditions, paying attention to identification issues in structural simultaneous equation systems and testing linear restrictions. The second part of the course discusess econometric modeling under serial dependence and unobserved heterogeneity, which includes time series modeling and causality analysis in dynamic models. The third part of the course covers asymptotic inferences in non-linear in parameters models, paying particular attention to generalized method of moments and maximum likelihood. The last part of the course discuses inference tools in quantile regression, non-parametric models, semi-parametric models, and specification testing.
