T he factthattechnical ine¢ dency is purely stochastic; opens up a way
outofpoverty and non-cuali.cation to the sons ofnon-cuali.ed agents. In

mobility. T able 7 summarizes the evolution ofthe occupationaldistribution
in this case.

T able 7: evolution of occupational distribution in scenario I (progenitors !long-run)
T herefcre the stochastic transm i ssi on oftechni ca l i ndî ci ency bri ngs about
the possibility of social climbing. In the long-run the whole population is
cμaii...ed
In scenario III the situation is symmetric: in the long-run the whole
population is trapped in poverty and in non-cuali.cation and distributed
on the support[0.111732;0.50 2 8] . M ostofthe people are workers (76.66%).
Themean wealth is lower(0.156). The long-run occupationaldistribution is
summarized in Table8.
