On the link between HIV prevalence and health expenditure : an asymmetric analysis

Purpose: Individuals' health is considered one of the major determinants of higher levels of productivity and economic development. Over the past century, the widespread occurrence of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has been a serious threat to economic development around the globe and has caused a dramatic fall in the life expectancy rate in many nations. This is the first study that examines the impact of HIV prevalence on health expenditure at the national level employing two linear and nonlinear autoregressive distributed lag (ARDL) models and simultaneously tests the long-run and short-run relationship for five selected developed countries. The authors employ annual data from 1981 to 2016. They find that HIV prevalence has a significant impact on health expenditure in the short-run and long-run in all five countries using the linear model and four of the countries in the nonlinear model. They find that HIV/AIDS prevalence has a significant short-run and long-run asymmetric impact on health expenditure of almost all selected developed economies. Design/methodology/approach: The authors are employing two linear and nonlinear ARDL models and simultaneously test the long-run and short-run relationship for five selected developed countries. Findings: The authors find that HIV/AIDS prevalence has a significant short-run and long-run asymmetric impact on health expenditure of almost all selected developed economies. Originality/value: To the best of the authors’ knowledge, this is the first research work that empirically examines the link between HIV prevalence and health expenditure for this group of countries using linear and nonlinear ARDL approach for short run and long run.
