PSIIPrivate Sector Influence Index

Methodology

Plain-English PSII Core v2 methodology

PSII Core v2 is an annual, versioned, cross-national structural index. It screens for conditions associated with resilience or susceptibility to undue private-sector influence in strategic and policy environments.

Score direction: higher = more resilient / less structurally susceptible. Scores are displayed to 3 decimals at most.

Version separation

PSII Published v1

The 2023 published edition is archival and tied to the original publication. It should not be merged into the annual Core v2 rankings.

PSII Core v2

The annual structural index uses the revised v2 methodology. It is resilience-oriented and not numerically identical to the chapter table.

Score formula

Each dimension is an arithmetic mean of normalized indicators. The overall Core v2 score applies theory-led weights:

Governance & elite capture
50%
Economic structure & external dependence
35%
Information environment & media independence
15%

Governance & elite capture

  • WGI Control of Corruption
  • WGI Rule of Law
  • WGI Regulatory Quality
  • WGI Government Effectiveness
  • WGI Voice and Accountability
  • V-Dem Egalitarian Democracy Index
  • V-Dem Political Corruption Index, inverted
  • Transparency International CPI

Economic structure & external dependence

  • OECD FDI Regulatory Restrictiveness Index, inverted
  • UNCTAD export product concentration index, inverted
  • UNCTAD export market concentration index, inverted
  • UNCTAD import market concentration index, inverted

Information environment & media independence

  • V-Dem Freedom of Expression and Alternative Sources of Information
  • RSF Press Freedom Index

Release discipline

A canonical annual release requires all core indicators for the same reference year, one frozen source vintage per provider, and explicit release metadata.

No hidden imputation is allowed. If a country-year is missing any core indicator, its score status is incomplete and unavailable scores remain null.

Public caveats that stay visible

  • Structural, not event-level: PSII does not prove who influenced whom.
  • Governance-heavy by design: the index is theory-led.
  • Authoritarian comparability remains imperfect, especially for information controls.
  • Provider edition revisions can change historical scores across releases.
  • Core v2 is revised and is not numerically identical to the published v1 chapter table.
  • No canonical 2025 release is present in this Sprint 0 shell.
