The Determination of Output
The demand for goods is an increasing function of output. Equilibrium requires that the demand for goods be equal to output.
Equilibrium in the Goods Market

The Determination of Output
Note two characteristics of ZZ: Because it’s not assumed
that the consumption and investment relations in Equation (5.2) are linear, ZZ is, in general, a curve rather than a line.
ZZ is drawn flatter than a 45-degree line because it’s assumed that an increase in output leads to a less than one-for-one increase in demand.

Deriving the IS Curve
•An increase in the interest rate decreases the demand for goods at any level of output.

Deriving the IS Curve
•Equilibrium in the goods market implies that an increase in the interest rate leads to a decrease in output. The IS curve is downward sloping.
