The article examines how African countries' economies are growing closer together over time. By looking at data from 2000 to 2015, the researchers found that countries with higher initial income levels tend to grow faster. They also discovered that countries' growth rates are influenced by their neighbors' income levels. The study used a special method to analyze the data and found that economies in northern, central, and southern Africa are closely linked. Overall, the findings suggest that economic growth in Africa is affected by both individual country factors and interactions between countries.
