Panel Data AnalysisHypothesis Testing • Panel Data Model Specification • Pool or Not To Pool • Random Effects vs. Fixed Effects • Heterscedasticity • Time Serial Correlation • Spatial Correlation
Fixed Effects vs. Random Effects • Hypothesis Testing
Random Effects vs. Fixed Effects • Fixed effects estimator is consistent under H0 and H1; Random effects estimator is efficient under H0, but it is inconsistent under H1. • Hausman Test Statistic
Random Effects vs. Fixed Effects • Alternative Hausman Test(Mundlak Approach) • Estimate the random effects model with the group means of time variant regressors: • F Test that g = 0
Hypothesis Testing • Fixed Effects Model • Random Effects Model
Heteroscedasticity • The Null Hypothesis • Based on the auxiliary regression • LM test statistic is NR2 ~ 2(K), N is total number of observation (i,t)s.
Cross Sectional Correlation • The Null Hypothesis • Based on the estimated correlation coefficients • Breusch-Pagan LM Test (Breusch, 1980) • As T ∞ (N fixed)
Cross Sectional Correlation • Bias adjusted Breusch-Pagan LM Test (Pesaran, et.al. 2008)
Time Serial Correlation • The Model and Null Hypothesis • LM Test Statistic
Joint Hypothesis TestingRandom Effects and Time Serial Correlation • The Model • Joint Test for AR(1) and Random Effects
Joint Hypothesis TestingRandom Effects and Time Serial Correlation • Based on OLS residuals :
Joint Hypothesis TestingRandom Effects and Time Serial Correlation • Marginal Tests for AR(1) & Random Effects • Robust Test for AR(1) & Random Effects • Joint Test Equivalence
Panel Data AnalysisExtensions • Seeming Unrelated Regression • Allowing Cross-Equation Dependence • Fixed Coefficients Model • Dynamic Panel Data Analysis • Using FD Specification • IV and GMM Methods • Spatial Panel Data Analysis • Using Spatial Weights Matrix • Spatial Lag and Spatial Error Models
