please hlp!!

1. Implement the excel formulas to get the aggregate demand curve with the complex model. Use the simple model for reference. Excel tips: notice the $ they stop the referenced cells from changing when you click and drag the formula? 2. Explain how changing (incr. and decr.) the following numbers affect the intersection of the AD curve with the 45 degree line You can manually change the numbers in your values column and inspect the graph, or just think about how they would atfect the equation 3. Compare the slope of the simpleand complex models. How do they affect the multiplier? 3.1 How would an expansionary fiscal policy, such as an increase in government spending affect AD 3.1.1 Using the simple model parameters: CO=2,cl=0.5,10=1,G=0,NX=0 (this is unchanged) what is the multiplier effect? The number: Explain how you got that number: (Notice there are two ways we can solve it, graphically, and analytically) 3.1.2 Explain the effect in the complex model: (you do not need a number, but it may help your rationale? 3.2 .1 Using the simple model parameters: c0=2,cl=0.5,10=1,6=0,NO=0 (this is unchanged) what is the multiplier effect? The number: Explain how you got that number: 3.2.2. Explain the effect in the complex model: (you do not need a number, but it may help your rationale)
