of firms or wealthy dynasties. The c mtinueace of the steady xx 
state with unchanged distribution is accompanied by a steadily 
growing size of the sample whidh produces over larger firms, 
wealth holdings etc. These large units always existed potentially 
but could not be realijrod sdt as long as the sample was too smallj 
with the growth of the economy such potential sizes become actual 
and in consequenoe the largest units represent a greater and greater 
share of the total although the theoretical distribution is 
unchanged. With the finite life and the stable population
