题目：Estimation and Inference of Dynamical Semiparametric Famma-French Factor Models *
报告人：尤进红 上海财经大学 常任轨教授
摘要：
In this paper, we propose a novel Famma-French factor Models, namely dynamical semiparametric Famma-French factor model which could accommodate both of the nonlinear effect of Famma-French factors and the time effect. By combining the spline and local polynomial techniques we develop a spline backfitted local polynomial method to estimate the unknown functions. In addition, the factor loadings are estimated across individuals by the least square method. The large sample properties of the proposed estimators are derived as well. Moreover, In order to test whether the effect of the factors is dependent on the time and whether the cross individuals share a common time trend. We propose generalized likelihood ratio tests to check them. It is shown that these tests are consistent. Simulation studies investigating the finite sample performance of the estimation and model diagnosis methods confirm the validity of our asymptotic theory. A financial data analysis is also considered.
