Which change will NOT increase the productivity of labour?

Question

Quizplus · Accepted Answer

An increase in the size of the labour force may not necessarily increase the productivity of labour. If the new workers are not properly trained or equipped with the necessary tools and technologies, their addition to the labour force may even decrease productivity. The other options - technological improvements, an increase in the capital stock, and improvements in education - are all factors that have the potential to increase productivity.
