Question: Explore further growth regressions for the OECDGrowth data using the augmented and extended Solow models of Nonneman and Vanhoudt (1996), which consider the additional regressors log(school) (human capital) and log(randd) (technological know-how), respectively. First, replicate the OLS results from Nonneman and Vanhoudt (1996, Table IV), and subsequently compare them with the resistant LTS results by adopting the strategy of Zaman et al. (2001).
