Multiplier Accelerator Theory of Investment

Lecture 13


Essence of the Multiplier-Accelerator Theory of Investment

  • Change in demand requires change in Capital stock

  • New Investment meets this requirement

  • Investment has multiplier effect on income

  • There is more demand

  • More demand for capital stock

  • More investment and more output

  • This process continues, until the economy reaches turning point

  • There is a similar downward movement in output, investment and capital stock in the recessionary period.
