Why the poor do not expropriate the rich : an old argument in new garb *

We consider a political economy with two partisan parties; each party represents a given constituency of voters. If one party (Labour) represents poor voters and the other (Christian Democrats) rich voters, if a redistributive tax policy is the only issue, and if there are no incentive considerations, then in equilibrium the party representing the poor will propose a tax rate of unity. If, however, there are two issues – tax policy and religion, for instance – then this is not generally the case. The analysis shows that, if a simple condition on the distribution of voter preferences holds, then, as the salience of the non-economic issue increases, the tax rate proposed by Labour in equilibrium will fall – possibly even to zero – even though a majority of the population may have an ideal tax rate of unity.  1998 Elsevier Science S.A.
