Socioeconomic and Structural Drivers of Elite Sporting Achievement: An empirical Cross-National Analysis

Abstract

The paper explores the Olympic medal success determinants across 28 national delegations through the interrelationship between sports funding, socio-economic variables, and developmental features. In this regard, a Poisson regression model will be used to determine the effects of financial investment, population size, gross domestic product (GDP), Human Development Index (HDI), and level of national development on the number of total medals. The results of the empirical tests indicate that HDI, GDP, and population size are strong and significant predictors of the medal performance, but the impact of sports investment is positive but insignificant. Diagnostic tests are used to identify the existence of overdispersion; however, Poisson specification will still provide useful information on the underlying structural patterns. The calculated average marginal effects also highlight the strong practical role of human development and economic power on athletic performance. In turn, the findings imply that, in the long-run, developmental variables have a stronger determining effect on the international sporting success than the financial support.
