Methodology for Services Trade Restrictiveness Index

 

The STRI Methodology

The STRI scoring methodology uses binary scores. Most measures in the STRI regulatory database have binary answers (yes/no) and binary scores are applied directly. Measures that have numerical answers are broken down on thresholds to which binary scores are applied.

Some measures constitute hierarchies where one or a combination of a few measures would close a market segment or a mode of supply to foreign suppliers. In other cases a restriction on one measure would render others irrelevant. The scoring methodology captures such hierarchies by conditioning the scoring on measures on the answers to questions higher up in the hierarchy of measures.

Some measures are complementary. These are bundled together in the scoring methodology such that if one measure in the bundle is scored as a restriction, all of them are.

The methodology note explains the thresholds, hierarchies and bundling of measures. It starts with the horizontal measures that are included in all sectors, followed by sector-specific scoring methodologies.
