The dynamics of the dynasty coming from non-cuali.ed entrepreneur
are a little bit more complex. In this case dynasties characterized by a
level of ineX dency lower than e = 1 ∣ i(x-b)(1-7)-h = о,23233 succeed in

Theevolution ofthe occupationalstructure ofthe population is summa-
rized in table 2-3: in the long-run 54% ofthe population do not invest in
education. 53.66% ofthe population consists ofunskilled workers. The re-

A verage wealth increases, from 0.5 to 2.8 6, thanks tothe increase ofthe
cuali.ed entrepreneurialshare ofthe population6.
6A verage wealth is also an indicatorofaggregate utility. A ctually, given preferences,
aggregate utility is an increasingfunction ofaggregate income. Ifpopulation is constant,
aggregate utility is alsoan increasingfunction ofaverage income and wealth.
