Parameter Heterogeneity and Model Uncertainty in Growth Empirics
Prof. Chris Papageorgiou (Louisiana State University) - March 19-21, 2007
Recent papers by Brock and Durlauf (2000) and Durlauf (2001) argue that the conventional Mankiw, Romer and Weil (1992) cross-country linear regression model imposes strong homogeneity assumptions on the growth process. Assuming parameter homogeneity in growth regressions is equivalent to assuming that all countries have an identical Cobb-Douglas (CD) aggregate production function. This is clearly an implausible assumption as there is nothing in the empirical or theoretical growth literature to suggest that the effect of a change in a particular variable (such as education or the savings rate) on economic growth is the same across countries. In the words of Brock and Durlauf “... the assumption of parameter homogeneity seems particularly inappropriate when one is studying complex heterogenous objects such as countries.”
