Employment Growth of Small, Medium, and Large Firms: Evidence from Zambia

We have used the World Bank Enterprise Survey data and examined the relationship between size, age and employment growth of 720 small, medium and large firms from four cities in Zambia. These firms have between 1-2010 full-time employees and operate in services, retail, and manufacturing sectors. The employment growth is defined as a difference in logarithm of full-time employees between two years and divided by the age of the firm. Our estimation shows that there is a strong relationship between employment growth, size, and age of firms. We find that younger firms but not smaller size are more important in creating employment growth.
