Work through the GIC index on indicator values you supply. The paper draws its four proxies from the WTO, OECD and World Bank; this tool does not fetch them, and it does not score any country.
How it works: The GIC Index combines two friction pressure indicators (regulatory burden entering the system) against two interoperability capability indicators (institutional quality that absorbs complexity). Higher scores mean more friction.
Friction Pressure vs Capability Offset
Formula
GIC = w1·FPWTO + w2·FPPMR − w3·ICOECD − w4·ICWGI
(0.25×35 + 0.25×30) − (0.30×75 + 0.20×85)
Raw: -23.25 → Scaled: 38.4
Moderate Friction: Some regulatory friction present but offset by reasonable institutional quality. Room for improvement in either regulation or governance.
Set each indicator from the published source yourself. Friction pressure indicators (FP) push the score up; interoperability capability indicators (IC) pull it down.
No country is scored here, and that is deliberate. The GIC paper specifies this index — variables, sources, normalisation, weights, dataset schema — and stops before scoring anything, reporting no country score and no ranking. This calculator does the same: it shows you what the formula does with values you supply. It does not tell you what any country’s values are.
Rate of new trade-relevant regulatory notifications entering the system
Economy-wide regulatory restrictiveness and barriers to entry
Strength of impact assessment, consultation, and ex post review
Ability to formulate and implement sound regulation
