Fiscal Rules and Councils: Most Effective When Used Together
Posted by Elif C. Arbatli [1]
Adopting numerical fiscal
rules has been an integral part of the policy response to the medium-term fiscal
consolidation challenge posed by the global financial crisis. According to Schaechter
et. al. (2012), since 2009, at least 16 countries have adopted new national
fiscal rules and many others are in the pipeline. The crisis has also revealed
the need for reforming supranational rules, such as the Stability and Growth
Pact of the EU and as a result new structural budget balance rules will be
adopted in almost all of the EU member states as part of the “fiscal compact.” A
recent paper by Charles Wyplosz titled “Fiscal Rules: Theoretical Issues and
Historical Experiences,” is a timely review of the theoretical underpinnings of
fiscal indiscipline and how numerical fiscal rules can help. Wyplosz argues
that fiscal rules are neither necessary nor sufficient to achieve fiscal
discipline; but that thoughtfully designed fiscal rules can be effective when
supplemented with fiscal institutions (and in particular fiscal councils) that
are tailored to the political institutions of the country.[2]
The paper first looks at the theoretical underpinnings of fiscal indiscipline, known as the “common pool problem”. The common pool problem arises when the beneficiaries of public spending or tax policies do not take into account the externalities that these policies impose on other groups (within a population, across different generations, among different levels of government or different states within a monetary union). Fiscal rules can in principle reduce these externalities by imposing explicit principles for fiscal behavior and thereby lowering the scope for deficit bias. According to Wyplosz, there are two key challenges: 1) fiscal rules cannot be fully contingent and hence they are subject to the “time-inconsistency problem” and 2) fiscal rules cannot be fully binding since they can be manipulated, changed or simply ignored. He argues that fiscal institutions (in particular, fiscal councils or other arrangements that give authority to an independent body to interpret rules) can help overcome these challenges.
