Product Market Regulation: Robustness and Critical Assessment 1998-2003-2007
The construction of a composite indicator (CI) involves stages where choices have to be made: the structure of PMR in domains and sub-domains, the normalization of the original data, the weighting of indicators, domains and sub-domains, and the aggregation method. All these choices will affect both the ranking and the message brought by the CI in a way that deserves analysis and corroboration. Robustness analysis is a powerful tool to test the sensitivity of PMR ranking to the different methodological assumptions. In particular we are interested in three questions. Does the use of one construction strategy versus another provide actually a partial picture of the countries¿ performance? Which countries have large uncertainty bounds in their rank (volatile countries)? Which are the factors that affect the countries rankings? We employ two strategies to answer to these questions. We consider each methodological choice individually and we study its effect on PMR ranking and we consider all the possible sources of variability together and study its joint effect on the PMR ranking.
