a. There are 3 endogenous variables in the model: Y, C, and I⁰.
b. The endogenous variables are Y, C, and I⁰.
c. The exogenous variables in the model are G⁰ and the parameters a and b.
d. The parameters in the above models are a and b.
e. In the model, the parameter b represents the marginal propensity to consume (MPC). It shows the proportion of additional income that a consumer will spend on consumption. In other words, it indicates how much of a change in income will lead to a change in consumption.
