Distributive interdependencies in liberal egalitarianism

Liberal egalitarian theories of justice share the egalitarian ideal that inequalities due to factors beyond individual control should be eliminated. This justifies that individuals sometimes receive more (or less) than their marginal productivity, which in turn implies that a change in one individual’s effort sometimes will affect the post-tax income of others. What restrictions should we place on such distributive interdependencies? The article provides characterizations of three main classes of redistribution mechanisms on the basis of how this question is answered.
