A COMMON POOL THEORY OF DEFICIT BIAS CORRECTION

Abstract

The budget deficit bias is modeled as the result of a domestic common pool problem and of an international externality. Along with Piguvian taxes, a number of policy measures are examined and welfare-ranked: deficit ceilings, golden rules and delegation. In general, the combination of delegation and an optimally-set deficit ceiling deliver the social optimum, even if the deficit ceiling is not credible.
