The main goal of the study was to figure out what factors have been driving economic growth in Sri Lanka. The researchers found that in the 1980s, most of the growth was because of more people working. But as time went on, other things like how efficiently people were working (total factor productivity) became more important. To keep growing well, Sri Lanka needs to have a stable government and economy, make changes to be more productive, manage money better, and give businesses more room to grow.
