Policy makers need to know how to boost economic growth in emerging markets. Entrepreneurship plays a big role, but not all types are helpful. A study looked at 20 emerging countries from 2011 to 2018 and found that high-growth expectation entrepreneurship has the biggest positive impact on growth. Innovative entrepreneurship is good too, but not as strong. On the other hand, necessity-driven and informal entrepreneurship can actually hurt growth in these markets.
