Use of Economic Instruments in Water Policy ― Insights from International Experience

This book assesses both the effectiveness and efficiency of implemented Economic Policy Instruments (EPIs) in order to achieve water policy goals and identifies the preconditions under which they outperform alternative (e.g. regulatory) policy instruments and/or can complement them as part of complex policy mixes. The development of a consolidated assessment framework helps clarify (and where possible, quantify) the effectiveness of each EPI on the basis of different criteria. Outcome-oriented criteria describe how the EPIs perform. They include intended and unintended economic and environmental outcomes and the distribution of benefits and costs among the affected parties. These steps consider the application of cost effectiveness and cost benefits analysis, e.g. to assess ex-post performance of the EPI. Process criteria describe the institutional conditions (legislative, political, cultural, etc.) affecting the formation and operation of the EPI studied (particularly relevant for assessing the possible impacts of using economic instruments), the transaction costs involved in implementing and enforcing the instruments and the process of implementation.
