2. Which one of the following statements is INCORRECT? Select one:
A. When we introduce investment as an endogenous variable to our
goods market model our equilibrium equation changes from Y = Z = c0
+ c(Y – T) + Ī + G to Y = Z = c0 + c(Y – T) + I(Y,i) + G.
B. In the goods market model, investment spending is regarded as an
autonomous variable, but according to our analysis in the IS-LM model,
the investment function will change from I = Ī to I = I(Y, i).
C. When firms increase their spending on capital goods, it implies that the
expected return rate of these investment projects is higher than the
market interest rate.
D. Consumption is a positive function of the level of output and income,
whereas investment is a positive function of the level of output and
income and the interest rate.

and the equilibrium level of output and income falls.
C. government spending increases, the demand for goods increases and
the equilibrium level of income rises.
