Productivity dispersion and the roles of quality of labour input and competition: A case of Vietnamese manufacturing sector

This paper examines the roles of cost of labour input and competition on productivity dispersion in the Vietnamese manufacturing sector. We look at the effect accounting for labour input quality has on explaining productivity dispersion. This paper tests the hypothesis that mismeasurement of labour input may play a role in large productivity dispersion. We use the cost of labour input of firms as a proxy measure of labour input quality to examine whether incorporating this measure accounts for a part of the productivity dispersion. The paper also examines the role of competition in the extent of productivity dispersion.
