In this study Eric Helland and Alex Tabarrok focus on Baumol’s cost disease, also known as the Baumol effect, and point to the increase in the cost of skilled labor as an explanation of why expenditures in education and healthcare have consistently increased while quality and productivity have risen at a much slower rate. The Baumol effect tells us that to control costs, industries must increase output from the same inputs or use fewer inputs in order to offset the rising opportunity costs of those inputs.
