讲座内容摘要:

This paper focuses on estimating the coefficients and average partial effects of observed regressors in nonlinear panel data models with interactive fixed effects, using the common correlated effects (CCE, hereafter) framework. The proposed two-step estimation method involves applying principal component analysis to estimate the latent factors based on cross-sectional averages of the regressors in the first step, and jointly estimating the coefficients of the regressors and the factor loadings in the second step. The asymptotic distributions of the proposed estimators are derived under general conditions, assuming that the number of time-series observations is comparable to the number of cross-sectional observations. To correct for asymptotic biases of the estimators, we introduce both analytical and split-panel jackknife methods, and confirm their good performance in finite samples using Monte Carlo simulations. Finally, the proposed method is used to study the arbitrage behavior of non-financial firms across different security markets.

本文使用共同相关效应(CCE,以下简称)框架,估计了具有交互式固定效应的非线性面板数据模型中的回归系数和平均部分效应。所提出的两步估计方法在第一步中应用主成分分析来估计基于解释变量的潜在因子,并在第二步中联合估计解释变量的系数和因子载荷。所提出的估计式的渐近分布是在一般条件下推导的,假设时间序列观测的数量与横截面观测的数量相当。为了纠正估计量的渐近偏差,我们引入了分析和分割面板刀切法,并使用蒙特卡罗模拟确认了它们在有限样本中的良好表现。最后,利用所提方法研究了非金融企业在不同证券市场的套利行为。
