Bias Reduction for Dynamic Nonlinear Panel Models with Fixed Effects
Fixed Eff ects Dynamic Nonlinear Panel Models
2015/9/22
The fixed effects estimator of panel models can be severely biased because of well-known incidental parameter
problems. It is shown that this bias can be reduced as T grows with n. We con...
Two models for the parametric forcing of a nonlinear oscillator
Parametric excitation Resonance Chaos Elliptic averaging
2015/8/27
Instabilities associated with 2:1 and 4:1 res-onances of two models for the parametric forcing of a strictly nonlinear oscillator are analyzed. The first model involves a nonlinear Mathieu equation an...
