The study looked at what factors affect economic growth in Sierra Leone from 1980 to 2018. They used math to analyze eight big economic factors and found that foreign investment, capital formation, and population growth all help the economy grow. But trade openness, exchange rate changes, credit rates, and remittances can slow down growth. Even though there was a war and an Ebola outbreak during the study period, they didn't have a big negative impact on economic growth. The researchers also found a long-term connection between economic growth and these factors. In the short term, the economy tends to correct itself towards this long-term balance.
