We introduce pollution, as a by-product of production, into a non-tournament model of R&Dwith spillovers. Technology policy takes the form of either R&D subsidisation or pre-competitiveR&D cooperation. We show that, when the emissions tax is exogenous, the optimal R&Dsubsidy can be negative,...

This note investigates the extension of Roberts' price-independent welfare prescriptions toalternatives in which population size and composition can vary. We show that ethicallyunsatisfactory orderings result. Suppose that a single person is to be added to a populationthat is unaected in utility...

In pure population problems, a single resource is to be distributed equally among theagents in a society, and the social planner chooses population size(s) and per-capita consumption(s) for each resource constraint and set of feasible population sizes within thedomain of the solution...
