The relationship between government and parents is modelled as a principal-agent problem, with the former in the role of principal and the latter in the role of agents. We make three major points. The first is that, if the well-being of the child depends not only on luck, but also on parental...

The effects and optimal choice of policy instruments affecting the family (child benefits, taxes on child-specific commodities, etc.) are examined within the context of a household economics model with fertility choice. The simultaneous consideration of child benefits and commodity taxes in the...

Higher education is not just a signal of innate ability. At least a certain level of educational achievement (degree level, degree mark) is strictly required to perform a graduate job. School leavers fall into two categories, the rich and the poor. Ability is distributed in the same way in both...

We examine the effects of differences in social capital on first and second best transfers to families with children, in an asymmetric information context where the number of births, and the future earning capacity of each child that is born, are random variables. The probability that a couple...

We demonstrate that the notion of a "family constitution" (self-enforcing, renegotiation-proof family norm) requiring adults to provide attention for elderly parents carries over from a world where sexually indifferentiated individuals reproduce by cell separation, to one where individuals...

Student loans, even income-contingent ones, are not optimal. Potential university students with the appropriate characteristics should be offered a scholarship, dependent on both need and merit. The award of the scholarship should be conditional on the choice of university degree, but students...

How does the distribution of individual preferences evolve as a result of marriage between individuals with different preferences? Could a family rule be self-enforcing given individual preferences, and remain such for several generations despite preference evolution? We show that it is in a...

The intersection of Economics and Nature has long been overlooked, but recent events have shed new light on their interconnectedness. This paper explores this relationship, focusing on the impact of economic cycles and the role of GDP as a measure of economic success. The paper highlights the...

We analyze optimal compensation schedules for the directors of two plants belonging to the same owner and producing the same good but serving geographically differentiated markets. Since the outcome of each director depends on his own effort and on a random variable representing market...

The hypothesis of non-satiation of rational choice theory is very seldom posed under scrutiny, maybe because it is taken as an anthropologic reality. Looking closer to that, we discover that it is taken for granted only in economic theory, and that it has become a reality as a result of a...
