How does the economy return to equilibrium in response to changes in aggregate demand (AD) and aggregate supply (AS) in both the short run and long run.

What is short term aggregate supply and how does it differ from long term aggregate supply? Also, what can an economy do that desires to increase long term aggregate supply?

Some politicians have suggested tying the minimum wage to the consumer price index (CPI). Using the AD/AS diagram, what effects would this policy most likely have on output, the price level, and employment?

What are the major factors that will affect short-run aggregate supply and long-run aggregate supply?

What are the four reasons why aggregate demand curves might shift? Briefly explain each one of them.

Why does the economy's aggregate demand curve have a negative slope?

Briefly explain how each of the following events would affect the aggregate demand curve a) an increase in the price level b) an increase in government purchases c) higher federal corporate income taxes
