We propose four different GMM estimators that allow almost consistent estimation of the structural parameters of panel …

. For these purposes, panel unit root tests are employed to improve power against univariate counterparts. Since cross … section correlation is a distinct feature of the underlying panel data, results are based on various second generation panel …

-1996, using a panel of 100 countries. Relying on the nonparametric poolability test of Baltagi et al. (1996), we find evidence of … structural stability of the relationship. We then specify a nonparametric panel data model with country-specific effects …. Estimation results show that this relationship is upward sloping. Nonparametric specification tests do not reject monotonicity …
