Growth again...

The classical Growth models particularly those of Robert Solow including the augmented one have been around for quite some time. It’s surprising that these models have been dominating the mainstream despite they not been convincing in explaining why there are variations in cross-country income levels across the majority of countries. I just disagree that the differences in the growth rates of countries can be explained by the differences in saving and population growth as proposed by Solow. Although some econometric studies “support” Solow’s view, the analysis isn’t rigorous in the depth and breath of its theoretic foundations. Of course it takes a lot of undertaking to change the current paradigm but it’s worth a try. I just believe that one day I’m going to achieve that.
