Services Trade Restrictiveness Index (STRI): Scoring and Weighting Methodology

This paper presents the scoring and weighting methodology for calculation of the services trade restrictiveness indices (STRIs) for 18 sectors. The STRIs are composite indices taking values between zero and one, zero representing an open market and one a market completely closed to foreign services providers. The scoring system is based on binary scoring. To reconcile the complexity of services trade restrictions with binary scoring, non-binary measures are broken down to multiple thresholds; complementary measures are grouped and scored as zero only if all measures in the bundle are not restrictive. Finally in cases where one restriction renders others irrelevant, those measures that are rendered irrelevant are automatically scored one. The paper presents the general methodology that applies to the core measures found in all sectors as well as sector-specific scoring where relevant.
