This paper provides country-specific information on fiscal rules in use in 81 countries from 1985 to end-September 2012. It serves as background material and update of the July 2012 Working Paper "Fiscal Rules in Response to the Crisis—Toward the 'Next Generation' Rules: A New Dataset" and is also available in an easy accessible electronic data visualization tool (

It also presents details on various characteristics of rules, such as their legal basis, coverage, escape clauses, as well as key supporting features such as independent monitoring bodies.
