- Consider a simple model, such as the one developed in this chapter. The table to the right shows the levels of desired consumption, desired investment, and desired aggregate expenditures for various levels of actual national income.arrow_forwardThe private consumption of Macroland is given by C=500+0.75Y and the private investment function is given by I=400−1000r, where r is the interest rate and Y is the GDP. The planned aggregate expenditure can therefore be written as PE=C+I=900+0.75Y−1000r. The equilibrium in the goods and services market happens when the planned expenditure is equal to the actual expenditure, or PE=Y Find the equilibrium GDP by solving the system of equations PE=900+0.75Y-1000r PE= Y for Y and PE. Note your solutions will depend on r! 1. Plot your solution for Y in a diagram measuring Y on the horizontal axis and r on the vertical axis. This curve is called the IS curve.arrow_forwardIn the aggregate expenditure model, what is NOT necessarily a characteristic of an economy in equilibrium?(a) The aggregate expenditure line is equal to the 45-degree line.(b) Aggregate expenditures are equal to income.(c) Investment equals saving.(d) Nothing is pressuring the economy to move to a higher or lower level of outputarrow_forward
