Analysis shows that higher government revenue improves teacher supply in 217 countries, suggesting governance quality is crucial for SDG 4 progress.
This study explores the relationship between government revenue per capita, governance quality, and the supply of teachers—an indicator under Sustainable Development Goal 4 (Target 4.c). Using annual data from 217 countries spanning 1980 to 2022, we apply a non-linear panel model with a logistic function that incorporates country-specific governance measures. Our findings reveal that increased government revenue is positively associated with teacher supply, and that improvements in governance amplify this effect. The model provides predictive insights into how changes in revenue may influence progress toward education-related SDG targets at the country level.
