Can Asteroid Mining Redefine Global Fairness? Models, Findings, and Policy Proposals

Interpretation of the 2022 MCM F‑Problem O Award Paper

Background

Most countries signed the 1967 UN Outer Space Treaty, which obliges space exploration and utilization to benefit all humanity regardless of economic or scientific development. The paper questions whether this principle can endure when asteroid mining becomes feasible and economically viable.

Problem Statement

The team must define global fairness, develop a measurable model, assess how future asteroid mining could affect fairness, explore how varying conditions influence this impact, and propose UN policies to promote equitable outcomes.

Methodology

A global‑fairness model is built using a multi‑level indicator system. Indicators are weighted by the entropy‑weight method (EWM) and validated with historical data from EU countries (1990‑2015) using the Regional Fairness Index (REI). K‑means clustering groups countries by a National Development Index (NDI). The model’s effectiveness is confirmed by comparing NDI‑based classifications with real‑world inequality measures.

For future asteroid‑mining scenarios, the authors assume government‑funded international collaboration. They apply fuzzy comprehensive evaluation to estimate industry impact, using the same fairness indicators as the evaluation set.

Additional analyses include factor analysis, multi‑objective planning, and Monte‑Carlo simulation to explore cooperation benefits, as well as sensitivity analysis by varying key parameters such as military expenditure, capital formation, per‑capita income, and higher‑education enrollment.

Key Results

The entropy‑weight method yields indicator weights; K‑means clustering divides nations into three development groups. The Global Fairness Index (GEI) is calculated from the average NDI of the highest and lowest groups. Validation with EU data shows the model reliably reflects fairness trends.

Scenario simulations indicate that when private enterprises fund mining, the impact on fairness differs from government‑funded cases. Sensitivity analysis reveals that increasing variance in military spending reduces its weight, while other indicators gain explanatory power.

Policy Recommendations

Based on the analyses, the authors propose eight UN policy measures, including: limiting and encouraging certain activities, establishing an Asteroid Mining Organization (AMO) to collect a portion of revenues for non‑mining nations, and creating a redistribution fund to accelerate fairness recovery. They suggest updating the Outer Space Treaty to explicitly address asteroid mining and to ensure benefits are shared globally.

Model Frameworks

Several model frameworks are presented, such as the Development & Equality (D&E) model, the Dimension‑Adaptive Fairness Evaluation (DAEA) model using Mahalanobis distance, and production‑distribution (P&A) models that incorporate marginal utility decay.

Images illustrating the indicator hierarchy, clustering results, and sensitivity analyses are included throughout the paper.
