About my research

Econometric analysis conducts the estimation of quantities of economic interest and the hypothesis testing about them using economic data, taking into account economic theory and the data generation mechanisms,. In addition, specification tests that examine whether the assumed economic theory is consistent with the data, and prediction using estimation results are also important objectives. My research interests are statistical theory in general especially for estimation and testing methods of semiparametric and nonparametric models, which avoid detailed parametric model specifications.
