This book examines the complex relations between democracy and social policy. Economic development is a necessary but not sufficient condition for welfare development. In industrial democracies, differences in the reach and organization of unions, presence of Left parties in government, and social pacts, account for much of the variation in welfare provision among countries. Social security is limited in democracies with low levels of industrialization, even though some countries with a social democratic orientation seem to have done well. Traditions of political rights, improvements in electoral competitiveness, and a pro-active judiciary may empower social movements to pressure governments in low-income democracies to introduce progressive social reforms.
