Altruism Efficiency & Health Expenditure

Abstract

In development economics, a key question is whether the link between clinical trial participation and healthcare spending reflects unequal global contributions to research. This study examined trials relative to healthcare spending in 53 countries using data from ClinicalTrials.gov and the World Bank. Africa’s average healthcare spending is about $41 per person, with 17.1 trials per million people, while the United States spends $12,555 per person and has 578 trials per million. When spending differences are considered, Africa’s participation appears relatively high, suggesting communities engage in research beyond what available healthcare resources might predict. This pattern is particularly evident in East Africa, where countries like Uganda (809 trials) and Kenya (788 trials) maintain notable trial activity despite limited investment in health systems. These findings suggest that trial participation may represent an important but often overlooked contribution from low-resource settings. However, caution is needed, as aggregated expenditure data may mask important variations within countries.
