✦ Synopsis


Masanjala and Papageorgiou (Rough and lonely road to prosperity: a reexamination of the sources of growth in Africa using Bayesian model averaging, Journal of Applied Econometrics 2008; 23(5): 671-682) use Bayesian model averaging to evaluate the existence of parameter heterogeneity between African and non-African countries in the framework of cross-country growth regressions. We show that their results are not robust to the use of a prior over the model space that respects the strong heredity principle put forward by Chipman (Chipman HA. 1996. Bayesian variable selection with related predictors. Canadian Journal of Statistics 24: 17-36) for models including interaction terms.

I am grateful to the commentators for bringing up two fundamental questions that are in fact related. Takagi and Kaneko look into a concrete molecular mechanism that could lead to the emergence of the genetic code [1], while Wallace takes the rate-distortion paradigm to the realm of proteins and ask
