This paper considers an economy where individuals differ in productivity and in risk. Rochet (1991) has shown that when private insurance markets offer full coverage at fair rates, social insurance is desirable if and only if risk and productivity are negatively correlated. This condition is...

This paper shows that the design of education policy involves a potential conflict between welfare and social mobility. We consider a setting in which social mobility is maximized under the least elitist public education system, whereas welfare maximization calls for the most elitist system. We...

This paper studies the determination of informal long-term care (family aid) to dependent elderly in a worst case scenario concerning the harmony of family relations. Children are purely selfish, and neither side can make credible commitments (which rules out efficient bargaining). The model is...

This paper re-examines the optimal tax design problem (income and commodities) in the presence of externalities. The nature of the second-best, and the choice of the tax instruments, are motivated by the informational structure in the economy. The main results are: (i) environmental levies...

We study the role and structure of commodity taxes when consumption and labor supplies are determined through a bargaining procedure between spouses, and where an optimal income tax is also available. We focus on the question whether there should be differences in tax treatment between "female"...
