Abstract This paper provides a review of economic studies analysing the use of multiple policies – a so‐called policy mix – to cope with single pollution problems. To guide and structure the review, an analytical framework is developed and applied. The framework integrates transaction costs into the analysis of pollution problems and policies to overcome them. Moreover, it understands a pollution externality not only as a market failure but more generally as the failure of private governance structures. Based on this insight, two rationales for using a policy mix are identified. First, a policy mix may help to correct for multiple reinforcing failures of private governance structures, such as pollution externalities and technological spillovers. Second, a policy mix can be employed if the implementation of single first‐best policies brings about high transaction costs, e.g. when marginal pollution damages are heterogeneous or polluters are unlikely to comply with the policy. For each rationale, the relevant literature is presented. Based on the review, avenues for future research are identified.
