Experiments evaluate the fit of human behaviour to the Shapley-Shubik power index (SSPI), a formula of voter power. Groups of six subjects with differing votes divide a fixed purse by majority rule in online chat rooms. Earnings proxy for measured power. Chat rooms and processes for selecting...

The paper reexamines the ethics of intergenerational risk. When risk re-solves gradually, earlier decisions cannot depend on the realization of later shocks and, consequently, some inequalities across generations are inevitable. To account for these inequalities, risky intergenerational...

The guiding principle of sustainability is widely accepted in today´s international policies. The principle contains two seperate objectives of justice with regard to the conservation and use of ecosystems and their services: (1) global justice between different people of the present generation...

Having Too Much is the first academic volume devoted to limitarianism: the idea that the use of economic or ecosystem resources should not exceed certain limits. This concept has deep roots in economic and political thought. One can find similar statements of such limits in thinkers such as...

I study the egalitarian way of distributing resources across generations. Distributional equity deeply conflicts with the Pareto principle: efficient allocations cannot guarantee that i) each generation be assigned a consumption bundle that is at least as large as an arbitrarily small fraction...

The paper reexamines the welfare economics of intergenerational risk. Risk and its resolution over time are modeled as a decision tree: in each period, the consumption of the current one-period living generation is to be traded-off against uncertain benefits of future generations; as time...

Undiscounted utilitarianism as a criterion of intergeneration justice has been questioned for different reasons: It has been argued (1) that any complete ordering of allocations with an infinite number of generations guaranteeing an optimal allocation must involve discounting, and (2) that...

The increasing loss of ecosystem services severely affects life perspectives of today's poor and future persons. Thus, governing the use of ecosystem services in an intragenerational and intergenerational just way is an urgent issue. I develop a conception of ecological justice that establishes...

Koopmans’s (Econometrica 28, 287–309) axiomatization of discounted utilitarianism is based on seemingly compelling conditions, yet this criterion leads to hard-to-justify outcomes. The present analysis considers a class of sustainable recursive social welfare functions within Koopmans’s...
