Life Benefit Efficiency Index (LBEI)

Contemporary macroeconomic frameworks evaluate national welfare primarily through monetary aggregates — Gross Domestic Product and its purchasing-power-parity variants. These share a foundational assumption: that money is the correct denominator of welfare analysis. This article challenges that assumption. Human life-time — irreversible, biologically finite, and universally equal at 24 hours per day — is the genuine primary resource that workers surrender in exchange for income. Money is only the intermediary. The true welfare question is: how many real goods and services does a person receive for one hour of life spent in labour? This global edition operationalises that question as the Life Benefit Efficiency Index (LBEI), now applied to a dataset of 162 countries covering all inhabited regions of the world — the first Human-Time Welfare Database of global scope. For each country and each basket good, the benefit coefficient Bᴵ = Wₕ / Pᴵ quantifies units of good i obtainable per net life-hour. Normalising against the global best performer yields Kᴵ; averaging across a 9-item core basket yields the composite LBEI. Data are classified into reliability grades A (official OECD/Eurostat), B (verified national statistics), C (mixed-source estimates), and D (indicative/conflict-affected), with results reported by grade. The global dataset reveals a welfare distribution far more unequal than monetary statistics suggest. Denmark leads the world (LBEI = 0.839) through institutional design — near-zero healthcare costs and controlled housing burden — rather than the highest wages. The United States (0.719, rank 2) presents the sharpest intra-basket paradox globally: world-best food efficiency coexists with near-zero healthcare efficiency (K_hlth ≈ 0). At the other extreme, the bottom decile of countries — concentrated in Sub-Saharan Africa and conflict-affected states — reports LBEI values below 0.130, implying that home ownership at median wages would require more than 30 years of uninterrupted full-time labour. The global mean LBEI is 0.255; the global median is 0.218, confirming a right-skewed distribution in which a small number of high-efficiency countries substantially exceed the central tendency. LBEI predicts World Happiness Report scores with r² = 0.601 against GDP PPP's r² = 0.401 — a 50 percent improvement — and predicts the Social Progress Index with r² = 0.682. Regression analysis confirms that LBEI provides statistically significant explanatory power beyond GDP PPP (ΔR² = +0.262, p < 0.001). An Absolute LBEI specification anchored to an Efficient Welfare Frontier eliminates sample-dependence and enables robust longitudinal tracking. Historical panel data (2010–2025) show universal deterioration in life-benefit efficiency among English-speaking countries (UK: −18.4%; US: −11.5%; Australia: −9.5%), driven primarily by housing costs rising far faster than wages, while rapid improvement is recorded in Central-Eastern Europe (Poland: +29.4%; Romania: +21.3%) and emerging Asia (China: +70.7%; India: +52.8%).
