Optimal policy intervention to reduce import dependence

Abstract

Should a country wish to reduce its dependence on imports of a certain commodity, an import tariff is typically recommended as the first-best (lowest-cost) policy instrument for achieving this non-economic objective. This note shows that while this is correct if the objective is to restrain imports to a certain quantity, it is not correct if the target is to reduce imports to a certain percentage of domestic consumption. In the latter case, a tariff-funded subsidy to producers is also required, the extent of which is larger the smaller the domestic price elasticities of demand and supply for the commodity. Show more
