Eco3min Research: editorial method and independence

Eco3min is published under the Eco3min Research byline, an independent publication dedicated to macro-financial analysis. Eco3min Research has no institutional, commercial or political affiliation. In line with French law, the publisher’s identity is on file with the site’s hosting provider; the framework is set out in the legal notice.

Origin and editorial approach

Eco3min Research starts from one observation: financial information has shifted toward real-time commentary, and the structural analysis that informs medium- and long-term decisions has become scarce in open-access sources. Eco3min publishes that work with no paywall: documented historical data, studies that place an episode within its cycle, and analyses that set out a mechanism along with its limits.

Editorial competencies

The work of Eco3min Research draws on the following competencies, each illustrated by a published page:

• macroeconomic analysis and monetary policy, for example the Fed funds rate as a reading of the cycle
• processing of long time series, for example every US yield curve inversion since 1976
• historical testing of indicators, for example the high yield spread as a leading indicator of the S&P 500
• interactive tools, for example the refining margin simulator
• Python programming for automated data collection and updates
• financial research writing in English and French

Production methodology

Every study and dataset published on Eco3min goes through the same process:

1. Topic selection: macroeconomic relevance, observed demand, gaps in accessible resources
2. Institutional sourcing: data taken only from recognized sources (list below)
3. Reproducible processing: automated pipeline (GitHub Actions, documented Python code), with updates following each source’s release schedule
4. Tools: Python and R for data and charts, with a large language model (LLM) assisting the production process. Production rule: published figures come from the primary sources cited on the page, not from the model, and the data behind studies and datasets can be downloaded as CSV.
5. Adversarial review: before publication, studies are tested against their strongest objections and their figures are checked against their sources
6. Compliance: texts are reviewed against the rules published in the editorial standards (no recommendation, descriptive framing)
7. Publication in two languages: most content exists in English and French, each version written for its own readers
