We find that segments of society who have shorter life expectancy can expect a lower retirement income and lifetime utility due to the longevity of other groups participating in the same pension scheme. Linking retirement age to average life expectancy magnifies the negative effect on the...

In this paper we study the effects on the survival rate in employment of a scheme that facilitates gradual retirement through working time reductions. We use information on the entire labour market career and other observables to control for selection and take dynamic treatment assignment into...

In several OECD countries age-targeted wage subsidies have been introduced to increase the employment of older workers, but evidence on their effectiveness is scarce. This paper examines the effects of a permanent wage cost subsidy in Belgium on the employment rate, working time and hourly wage....

Adult education can mitigate the productivity decline in aging societies if older workers are willing to learn. We examine a generous partial retirement reform in Germany that led to a massive increase in early retirement. Using county-level administrative data on voluntary education activities,...

Using population-level administrative data, we study labor market externalities stemming from age-specific employment protection legislation (EPL) targeted towards older workers. Our results show no economically meaningful overall effects of the EPL on employment or earnings of either men or...

We examine the investment rule that must be satisfied by an efficient and egalitarian path in a discrete-time version of the Dasgupta-Heal-Solow model of capital accumulation and resource depletion. In the discrete-time model, competitive valuation of net investments in terms of early and late...

We frame sustainability problems as bargaining problems among stakeholders who have to agree on a common development path. For infinite alternatives, the set of feasible payoffs is unknown, limiting the possibility to apply classical bargaining theory and mechanisms. We define a framework...

This paper focuses on two equity dimensions of climate policy, intra- and intergenerational equity, and analyzes the implications of equity preferences on climate policy, and on the production and consumption patterns in rich and poor countries. We develop a dynamic two-region model, in which...

Climate change is an externality since those who emit greenhouse gases do not pay the long-term negative consequences of their emissions. In view of the resulting inefficiency, it has been claimed that climate policies can be evaluated by the Pareto principle. However, climate policies lead to...

We examine utilitarian criteria for evaluating profiles of wellbeing among infinitely many individuals. Motivated by the non-existence of a natural 1-to-1 correspondence between people when alternatives have different population structures, with a different number of people in each generation,...
