Intergenerational discounting and inequality (with P.G. Piacquadio). [First draft.]
Pitch: We axiomatically characterize the theories of intergenerational justice that disentangle normative views on discounting from normative views on intergenerational inequality. A large family of criteria emerges, capturing many more ethical views than standard, including non-exponential discounting (e.g., hyperbolic discounting) or positional attitudes to inequality (e.g., Gini aggregation).
