Empirical observation equilibria: the Russian seaborne-crude corridor, 2021-2024

Can public shipping and port records identify the feedback between sanctions-evasion behavior and the observation system used to measure Russian seaborne crude?

Summary

A proposed empirical design for studying what public AIS tracks, port arrivals, and commodity-flow records can reveal about Russian seaborne crude as routes adapt to sanctions and observation. Data construction and identification remain under development; no empirical results exist yet.

Methods and notes

This project is in the empirical-design and data-construction phase and proposes using AIS coverage, port arrivals, and commodity-flow records. No empirical results exist yet, and identification and coverage remain under development.
