Arrow's theorem with social quasi-orderings

The collective rationality requirement in Arrow's theorem is weakened to demanding a social quasi-ordering (a reflexive and transitive but not necessarily complete binary relation). This weakening leads to the existence of a group such that (a) whenever all members of the group strictly prefer one alternative to another then so does society and (b) whenever two members of the group have opposite strict preferences over a pair of alternatives then the pair is socially not ranked. This theorem is then used to provide an axiomatization of the strong Pareto rule. These results are compared and contrasted to Gibbard's oligarchy theorem and Sen's axiomatization of the Pareto extension rule.     

Decentralization and local public finance in Tunisia

The Tunisian government has long admitted that its excessively centralized administrative and political systems have generated heavy costs in terms of inefficiency and citizen alienation. A major decentralizing reform effort was launched in the mid-1970s, the most important parts of which dealt with changes in local taxation powers, and in the sources and size of grants and loans which Tunisian communes receive from national sources. The result to date has been a modest increase in communal revenues from the new or increased taxes, and a more significant increase in central government grants to local governments. Smaller and more rural communes are heavily dependent on grants to undertake development actions, their tax base being negligible. The revised systefn generates more revenue, and distributes resources more equitably, than the previous arrangements. In theory, it gives a greatly increased latitude to elected communal councils. Nonetheless, the local governments-and the communes in particular-remain severely constrained by central government authorities. The conclusion is that the decentralization reform has been partial and halting, and will in all probability continue in the same manner.
