Baumol effect
In economics, the Baumol effect, or Baumol's cost disease, first described by William J. Baumol and William G. Bowen in the 1960s, is the tendency for wages in jobs that have experienced little or no increase in labor productivity to rise in response to rising wages in other jobs that did experience high productivity growth. In turn, these sectors of the economy become more expensive over time, because the input costs increase while productivity does not.
