The US economy is represented by the following equations: Z=C+I+G, C=300+.5YD, YD =Y T T =400, I =250, G=1000 Given the above variables, calculate the equilibrium level of output. Now assume that consumer confidence increases causing a rise in autonomous consumption (c0) from 300 to 500. What is the new equilibrium level of output? How much does income change as a result of this event? What is the multiplier for this economy?
