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...

We study the design of child-care policies when redistribution matters. Traditional mothers provide some informal child care, whereas career mothers purchase full time formal care. The sorting of women across career paths is endogenous and shaped by a social norm about gender roles in the...

Our model explains the observed gender-specific patterns of career and child care choices through endogenous social norms. We study how these norms interact with the gender wage gap. We show that via the social norm a couple's child care and career choices impose an externality on other couples,...

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"...

A fat and a healthy good provide immediate gratification, and cause health costs or benefits in the long run, which are misperceived. Additionally, the fat good (healthy good) increases (decreases) health care costs by increasing (decreasing) the probability of suffering from a chronic disease...

This paper studies the political economy of a basic income (BI) versus a means tested welfare scheme. We show in a very simple setting that if society votes on the type of system, its generosity as well as the "severity" of means testing (if any), a BI system could only emerge in the political...

Daughters are the principal caregivers of their dependent parents. In this paper, we study long-term care (LTC) choices by bargaining families with mixed- or same-gender siblings. LTC care can be provided either informally by children, or formally at home or in an institution. A social norm...

The tax regimes applied to couples in many countries including the US, France, and Germany imply either a marriage penalty or a marriage bonus. We study how they affect the decision to get married by considering two potential spouses who play a marriage proposal game. At the end of the game they...

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...

We show that once interfamily exchanges are considered, Becker's rotten kids mechanism has some remarkable implications that have gone hitherto unnoticed. Specifically, we establish that Cornes and Silva's (1999) result of efficiency in the contribution game amongst siblings extends to a setting...
