In section II of the paper, the authors survey some internationally renowned comparison index models, which include regulations and regulatory reform as a part of its comparison. The authors look at how these models calculate their final index numbers, and how they treat regulation.  In Section III, the authors develop the first of two index models to evaluate and compare regulatory systems and regulatory reform. The first, RRI_S, is based on theories of regulatory efficiency and regulatory reform. However, this method requires data which is not commonly available. To deal with this problem, in Section IV, the authors develop a second model, RRI_P, which uses the insights from various international comparison index models and regulatory theory, and tries to use data which is available from various international sources. Section V is a short conclusion.
