To this end, we estimate poverty elasticities relative to income and inequality, specifying two dynamic econometric models estimated via the generalized method of moments (GMM) system developed by Arellano and Bond (1991), Arellano and Bover (1995) and Blundell and Bond (1998). The model-estimated results prompt the conclusion that the income growth effect on poverty reduction is smaller when the initial development level is low. The same is found when the initial inequality level is high.
