This paper examines the roles of political and cultural factors in the
growth of less-developed countries. We begin by formulating a growth
model, similar to that of Baumol-Wolff (1988), based on the revised Su
mmers-Heston (1988) data set. We build upon this base model, using a p
riori information, to obtain further models which are capable of expla
ining growth in terms of politics and culture. We find that liberal re
gimes and Asian countries appear to have potentially high growth rates
of real GDP per capita.
