Can Health Human Capital Help the Sub-Saharan Africa Out of the Poverty Trap? An ARDL Model Approach

Abstract

This article explores the impact of health human capital on the poverty trap in Sub-Saharan Africa by autoregressive distribution lag model. In the long run, there is no evidence that health human capital can help the Sahara out of the poverty trap. While health human capital has a significant effect on poverty reduction in the short term. There is a threshold effect in the poverty reduction model of healthy human capital. When the economic development level reaches the threshold, the effect of poverty reduction is more obvious and deeper. The extended Solow economic growth model also proved that if the external human capital breaks through the threshold, it can make developing countries get rid of the poverty trap. Therefore, the economic development brought about by health care expenditure must benefit the poor in Sub-Saharan Africa and allow them to enjoy the welfare of social security.

Can the Profitability of Medical Enterprises Be Improved After Joining China's Centralized Drug Procurement? A Difference-in-Difference Design

“…Based on the panel data of 65 generic drug-listed companies in China from 2011 to 2020, this paper uses the double-difference method to evaluate the impact of drug centralized procurement policy of China on the net profit of enterprises and draws the following conclusions: first, before the implementation of the policy, the difference between successful enterprises and unsuccessful enterprises is not obvious. After the implementation of the policy, the net profit of the winning enterprise decreased significantly ( 25 , 56 – 58 ). Therefore, centralized drug procurement policy of China is not conducive to the improvement of enterprise net profit in the short term, and the effect is more obvious with the increase of policy implementation years.…”

“…Among them, there are three different views: one is that government centralized purchase promotes the growth of enterprise net profit through internal incentives ( 22 , 23 ). The other believes that due to information asymmetry, government intervention has an inhibitory effect on enterprise net profit ( 24 , 25 ). In addition, some scholars believe that the impact of centralized government drug procurement on the net profit of enterprises is uncertain.…”

“…Good health is also identified as one of the essential factors that can make economic growth possible in Sub-Saharan Africa (Ogundari and Awokuse 2018 ). Promoting national health insurance and strengthening the health system has emerged as a solution “to get rid of the poverty trap” in the Sub-Saharan region (Wang et al 2021 ).…”

“…In terms of the Sub-Saharan Africa region, a recent study has found that “to get rid of the poverty trap in this region, the government needs to promote the national health insurance and strengthen the health system as a whole plan” (Wang et al 2021 ). According to Ifeagwu et al ( 2021 ), 27 out of 48 countries in Sub-Saharan Africa are affected by direct out-of-pocket payments for healthcare services.…”
