Multilateral Subsidy Games. CEPR Discussion Paper No. 6479.
Centre for Economic Policy Research, London.
This paper examines the rationale for multilateral agreements to limit
investment subsidies. The welfare ranking of symmetric multilateral subsidy
games is shown to depend on whether or not investment levels are "friendly",
raising rival profits in total, and/or strategic complements, raising rival profits at
the margin. In both Cournot and Bertrand competition, when spillovers are low
and competition is intense (because goods are close substitutes), national welfare-
maximizing governments will over-subsidize investment, and banning
subsidies would improve welfare. When spillovers are high, national
governments under-subsidize from a global welfare perspective, but the
subsidy game is welfare superior to non-intervention.
