Balancing public goods in agriculture through safe minimum standards

Abstract

We develop a general framework in which public goods are conflicting (complementary) if an increase in the provision of one public good raises (lowers) the marginal cost of providing another public good. The framework is used to analyse the policy implications of maintaining safe minimum standards (SMSs) for two public goods. The comparative-static results are illustrated using a sector model for Norwegian agriculture in which the SMSs for food security, agrobiodiversity and greenhouse gas emissions are modelled as constraints. The simulations show that even if public goods are conflicting, better-targeted policies can achieve SMSs at lower social costs.
