Equitable Provision of Long-Term Public GoodsThe role of Negotiation Mandates

Abstract

We examine the international distribution of expenditures for the provision ofa global, long-term and uncertain public goods from the point of view of abenevolent planner. Even assuming a "no-redistribution" constraint, first periodexpenditures are in general progressive with income, and independent both fromtotal level of action, and from future distribution of damages. However, instatus-quo mandates-where current negotiating powers shape both present andfuture allocation-future distributions of efforts are very unequal, andagreement, if any, is at high risk of instability. An adaptative mandate provesnecessary to provide an acceptable solution.Equitable Provision; Long-Term Public Goods; Negotiation Mandates
