Nonparametric and semiparametric modeling and estimation procedures are now widely applied in econometrics. Their popularity generally comes from the reduction of the probability of misspecification compared with their parametric counterpart. My research is composed of two parts: a theoretical part on semiparametric efficient estimation of partially linear model and an applied part in energy economics under different dynamic settings.
