All industrialized countries have seen their populations ''urbanize''
over time. In democracies, this demographic trend ought to have ramifi
cations for politics and policy. In this paper, I examine the effects
of urbanization on agricultural subsidy programs in Japan and the Unit
ed States. I show that even after malapportionment was dealt with, rur
al retrenchment was delayed by the balance of power within the majorit
y party in each country. In Japan, once urban members constituted a ma
jority within the ruling party in the House of Representatives, govern
ment policy changed quickly and dramatically. In the U.S., powerful Ho
use committees and permanent rural over-representation in the U.S. Sen
ate delayed policy change much longer than was true in Japan, which ha
s no similar institutional impediments.
