About the Index

The AI-GPR Index measures geopolitical risk by applying large language models (LLMs) to newspaper articles. Building on the conceptual framework of the original GPR Index (Caldara and Iacoviello, 2022), it replaces keyword matching with semantic understanding: instead of searching for specific word combinations, GPT-4o-mini reads each article and assigns a continuous risk score from 0.0 to 1.0 based on the article's geopolitical content.

The index is constructed at daily frequency using articles from the New York Times, Washington Post, and Chicago Tribune, spanning 1960 through 2025.

AI-GPR

The main index. Aggregates LLM-assigned geopolitical risk scores across all newspaper articles on each date, normalized by total newspaper article count. Captures the overall level of geopolitical risk as perceived in the news.

GPR Original (Keyword-Based)

A keyword-based GPR index constructed using the Caldara and Iacoviello (2022) proximity search methodology on the same three newspapers. Counts articles matching specific combinations of geopolitical and risk-related terms. Extended back to 1960.

GPR Oil Disruptions

A sub-index identifying articles that discuss oil or energy supply disruptions driven by geopolitical events. Constructed using a second LLM classification layer applied to high-GPR articles containing oil-related keywords.

Methodology

Articles matching a broad keyword filter are scored by GPT-4o-mini on a 0–1 scale reflecting the intensity of geopolitical risk content. All indices are normalized to a mean of 100 over 1985–2019. See the paper for full details.
