“This study examines how effectively countries convert their economic and demographic resources into Olympic success. Using data from the 1996–2020 Summer Games and a random-parameter stochastic frontier model, we find that the average country operates at only 68% of its attainable performance frontier, and that sports diversification – competing across a broader range of disciplines – independently and meaningfully raises efficiency. Our findings suggest that Olympic success is not solely determined by the level of available resources: organisational quality and strategic event selection matter at least as much, and meaningful upward mobility within the efficiency distribution remains a realistic prospect for nations across the performance spectrum.”

Abstract
This paper presents the analysis of Olympic efficiency by introducing a weighted performance score that values both medals and near-podium finishes and by applying a random-parameters stochastic frontier model with heteroscedastic inefficiency to the Summer Games, 1996–2020. Unlike earlier studies, we allow production elasticities to vary across countries and examine the role of sports diversification in shaping efficiency. The results highlight the importance of broad participation across disciplines, showing that diversification not only raises potential output but also reduces inefficiency. Distributional analysis further reveals modest declines in inequality and meaningful opportunities for upward mobility, even as top performers persist. The findings suggest that efficient Olympic nations combine scale, diversification, and organizational quality, offering policy lessons beyond resource levels alone.
