The correct answer is Investment multiplier is positively related to MPC. 

Key Points:

  • The stimulating impacts of governmental or private investments are referred to as the investment multiplier.
  • It is based on John Maynard Keynes' economic theories.
  • The marginal propensity to save (MPS) and the marginal propensity to consume (MPC) determine the size of the investment multiplier (MPS).
  • An investment's potential to stimulate the economy more strongly is indicated by a higher investment multiplier. 

Additional Information:

  • The percentage of additional income that is spent on consumption is known as the marginal propensity to consume.
  • Depending on income, MPC fluctuates.
  • MPC tends to be lower at higher income levels.
  • The Keynesian multiplier, which describes the impact of the additional investment or government spending as an economic stimulus, is mostly determined by MPC.
