Public Healthcare Spending, Business Dynamism, and Wage Inequality: Evidence from Developed and Developing Economies

This paper examines the effects of public healthcare spending on wage inequality and social welfare in an economy with rural and urban regions. The objectives are twofold. First, we introduce a simple theoretical framework that captures the link between public healthcare spending and firms' output choice and subsequent wage provisions. We demonstrate that in the short run, a rise in public healthcare services can increase urban output and lower urban unemployment and raise both skilled and unskilled wage rates. In the long run, firm entry produces a business‐dynamism effect that enhances the rate of return on capital, reduces the unskilled wage rate and intensifies wage inequality. Second, we empirically test our theoretical predictions using data from 112 economies in the period 2006–2018. We find evidence supporting our theoretical findings concerning the effects of public healthcare on wage outcomes, especially in the long run. Results are highly consistent across the two groups: advanced economies (mainly OECD/European economies), and emerging and developing economies based on alternative measures for wage inequality, including the GINI coefficient and top income share. The paper provides useful information for the public healthcare policy.
