Abstract
Purpose –The objective of this study is to identify the main factors affecting pharmaceutical expenditures in the Organization for Economic Cooperation and Development (OECD) countries.Design/methodology/approach –In this study, it was investigated whether the university graduate rate(UNI), the unemployment rate(UNEMP), gross domestic productper capita (GDP) in Purchasing Power Parity (PPP $),and the number of physicians per 1,000 people (PHY) affected per capita pharmaceutical expenditures (PHAR)(PPP $) by using panel data analysis. The population of the study was 33 OECD countries whose data were available. The data consisted of the time period of 2013-2016. Results –GDP and UNIstatistically significantly increased PHAR (p<0.05). The UNEMPand PHYalso increased PHAR, but the effects of these variables were not found to be statistically significant (p>0.05). The variables included in the model explained 22% of the variance in PHAR.Conclusion –PHAR are affected by economic factors and sociodemographic factors as well as health systems' structure. Therefore, governments wishing to control pharmaceutical expenditures should also focus on these variables.
