    Recall the IS-LM model. In particular, the goods-market equilibrium condition was Y = C (Y − T ) + I (r) + G, and the money-market equilibrium condition was m = L (r, Y ). Here, the exogenous variables are G (government spending), T (taxes), and m (real money supply). The endogenous variables are Y (output, or income) and r (real interest rate). C (·) is the consumption function, which is increasing in disposable income Y − T , but...
