Are long-lived persons utility monsters
Nozick’s ‘utility monster’ is often regarded as impossible, because one life cannot be better than a large number of other lives. Against that view, I propose a purely marginalist account of utility monster defining the monster by a higher sensitivity of well-being to resources (instead of a larger total well-being), and I introduce the concept of collective utility monster to account for resource predation by a group. Since longevity strengthens…

Equivalent income versus equivalent lifetime: Does the metric matter
We examine the effects of the postulated metric on the measurement of well-being, by comparing, in the (income, lifetime) space, two indexes: the equivalent income index and the equivalent lifetime index. The conditions under which the equivalent lifetime index exists are more restrictive than the ones under which the equivalent income index exists, but it is possible to define an alternative equivalent lifetime index, based on two reference inco…
Vie brève, dommage et bien-être économique. Jalons pour une étude de la rareté du temps de vie
Les économistes mesurent le dommage causé par un décès en quantifiant le coût d’opportunité de ce décès (tout ce qui est perdu par le défunt à cause de ce décès). Ce calcul contredit la thèse de la neutralité de la mort défendue par divers philosophes depuis l’Antiquité. Cet article revisite plusieurs arguments anciens justifiant la neutralité de la mort et, par un effet de contraste, révèle des présupposés de l’analyse économique de la mort, tel…
The Stakeholder Corporation and Social Welfare
The stakeholder (or responsible) firm is dened in this paper as one that maximizes the (weighted or unweighted) sum of the surpluses of its customers and suppliers (including workers). We show that, although this objective is hard to empirically measure, it can be pursued by simple management rules that rely onconstrained profit maximization. We find that unconstrained prot maximization gives a competitive edge to ordinary firms, but that stakeho…

Life as a Trust Game: A comment on The Option Value of Life
According to Burri (2020), a major reason why suicide is often irrational lies in the option value of life. Remaining alive is valuable because this allows for a larger menu of options, and the possibility of committing suicide in the future adds further value to the act of remaining alive now. In this note, I represent life as a trust game played by two selves – the young self and the old self – and I argue that the possibility to commit suicide…
Premature deaths, accidental bequests, and fairness
While there is little agreement regarding the taxation of bequests in general, there is a widely held view that accidental bequests should be subjected to a confiscatory tax. We re‐examine the optimal taxation of accidental bequests by introducing a concern for compensating individuals for a premature death. Assuming that individuals care about what they leave to their children, we show that, whereas the 100 percent tax view holds under the utili…
The Value of a Life-Year and the Intuition of Universality
When considering the social valuation of a life-year, there is a conflict between two basic intuitions: on the one hand, the intuition of universality, according to which the value of an additional life-year should be universal, and, as such, should be invariant to the context considered; on the other hand, the intuition of complementarity, according to which the value of a life-year should depend on what this extra life-year allows for, and, hen…

Longevity, Health Spending, and Pay-as-you-Go Pensions
This paper aims at investigating whether or not a utilitarian social planner should subsidize longevity-enhancing expenditures in an economy with a pay-as-you-go pension system. For that purpose, a two-period overlapping-generations model is developed, in which the probability of survival to the second period can be raised by private health spending. Focusing on the steady state, it is shown that the sign of the optimal subsidy on health expendit…

Measuring Variations in Lifetime Welfare Ex Ante and Ex Post: Some Exploratory Calculations
Whereas longevity-adjusted consumption measures have become increasingly used as indicators of lifetime standards of living, it remained unnoticed that those measures, by relying on period - rather than cohort - life tables, constitute indicators of expected - rather than actual - lifetime standards of living. In order to estimate the actual gap between ex ante and ex post measures of lifetime welfare, this paper computes, for 19th-century Europe…

Long-Term Care Insurance Puzzle
In most Organization for Economic Cooperation and Development (OECD) countries, the era of long-term care (LTC) has arrived. More than two out of five people aged sixty-five or older report having some type of functional limitation (sensory, physical, mental, self-care disability or difficulty leaving home), and, as such, are not autonomous, and require adequate care.1 A few years from now, the ageing trend will accelerate, fuelled by the large ‘…
Long Term Care, Altruism and Socialization
The public provision of long-term care (LTC) can replace family-provided LTC when adults are not sufficiently altruistic towards their parents. But State intervention can modify the transmission of values and reduce the long-run prevalence of family altruism. To characterize the optimal LTC policy, we develop a three-period OLG model where the adult population is divided into altruistic and non-altruistic agents, and where the transmission of alt…

Childbearing Age, Family Allowances, and Social Security
Although the optimal public policy under an endogenous number of children has been widely studied, the optimal public intervention under an endogenous timing of births has remained largely unexplored. This paper examines the optimal family policy when the timing of births is chosen by individuals who differ as to how early fertility weakens future earnings. We analyze the design of a policy of family allowances and of public pensions in such a se…

Long-Term Care, Altruism and Socialization
The public provision of long-term care (LTC) can replace family-provided LTC when adults are not sufficiently altruistic towards their parents. But State intervention can modify the transmission of values and reduce the long-run prevalence of family altruism. To characterize the optimal LTC policy, we develop a three-period OLG model where the adult population is divided into altruistic and non-altruistic agents, and where the transmission of alt…
Rationalizability and interactivity in evolutionary OLG models
Fair Accumulation under Risky Lifetime
Individuals save for their old days, but not all of them enjoy the old age. This paper characterizes the optimal capital accumulation in a two‐period OLG model where lifetime is risky and varies across individuals. We compare two long‐run social optima: (1) the average utilitarian optimum, where steady‐state average welfare is maximized; (2) the egalitarian optimum, where the welfare of the worst‐off at the steady‐state is maximized. It is shown …
