In this top group, parliaments have substantial resources at their disposal, and a well-optimized committee system.
The USA is some senses in a class by itself, with far more staffing and research resources available to its members than is the case in any other OECD country. However, South Korea compares favorably to other nations in these categories as well, with a committee structure deemed close to optimal.
In this bottom group, elements of parliamentary committee structures are likely to be deemed inefficient, and the availability of expert staffing assistance is low.
Ireland, Austria and Luxembourg each have optimal committee sizes, but score comparatively poorly in terms of the number of committees. Mexico and the UK score particularly poorly on this committee count measure, with Austria improving substantially in this area since the SGI 2009, but remaining relatively far from optimum.
Expert staff resources are particularly limited for Luxembourg’s individual legislators, while Spain, Ireland and Luxembourg all offer comparatively slender research staff resources to the legislature as a whole.
