CLIMATE CHANGE AND PUBLIC HEALTH CARE EXPENDITURE IN NIGERIA
Keywords:
Government healthcare expenditur, Climate chang, OLS, , ECM, NigeriaAbstract
Despite the existence of various studies examining the effect of public health expenditure on health outcomes in Nigeria and other countries, as well as the relationship between public spending and CO2 emissions in other nations, this particular research focuses on the effects of climate change on public healthcare expenditure in Nigeria from 1990 to 2022. The study utilizes the Ordinary Least Squares and Error Correction Model (ECM) for estimation purposes. Unit root tests are conducted on variables such as carbon dioxide (greenhouse gas) emissions and population, which exhibit order zero I(0), while public healthcare expenditure per capita, gross domestic product per capita, and consumer price index exhibit order one I(1). To establish the long-term relationship between these variables, the Johansen co-integration test is employed. The results of the error correction model indicate a significant negative relationship between climate change and government healthcare expenditure, while population and gross domestic product per capita exhibit a significant positive relationship with government healthcare expenditure in Nigeria. Based on these findings, the study recommends that governments at all levels should strive to increase healthcare expenditure in the country, particularly during periods of climate change that affect people's health.
