An economy experiences a slowdown in its rate of real GDP growth from 5.2% in Year 1 to 1.8% in Year 2. Consequently, although national output continues to expand, aggregate planned capital investment by private firms falls significantly in Year 2. This relationship between a deceleration in output growth and a contraction in planned investment is best explained by:
the multiplier effect.
the wealth effect.
the accelerator principle.
the marginal propensity to import.
