Staff Position Notes (SPNs) showcase new policy-related analysis and research by IMF departments. These notes are generally brief, written in nontechnical language, and are aimed at a broad audience interested in economic policy issues, including staff involved in mission work, members of the Executive Board, and persons outside the Fund. This series replaced the Policy Discussion Papers series at the end of 2008. Most SPNs are around 25 pages, allowing for only a couple of simple equations and several tables and charts, which distinguishes them from the longer, and generally more technical, Working Papers.
This paper discusses how to enhance automatic stabilizers without increasing the size of government. We distinguish between permanent changes in the parameters of the tax and expenditure system (e.g., changes in tax progressivity) that will enhance the traditional automatic stabilizer, and temporary changes triggered by certain economic developments (e.g., tax measures targeted at credit and liquidity constrained households, triggered during a severe downturn). We argue that, with some exceptions, the latter are preferable as they can be implemented with lower disruptions in other fiscal policy goals (e.g., economic efficiency). Moreover, countries should also avoid introducing procyclicality as a result of fiscal rules, as these would offset the effect of existing automatic stabilizers.
