1. Describe intuitively with economic reasoning and show in a graph how September 11, 2001, impacted the AD/AS curve in the USA. Please demonstrate reasoning under the followings scenarios:

• State of panic in the economy
• Shortage of demand
• Lowering price expectation
• Increase in unemployment
• Lowering wages
• Lowering taxes
• Increase in money supply and reduction of target interest rate by the FED through Open Market Operations

2. Now suppose that the economy was in state of equilibrium before September 11, 2001:

• The aftermath of the recession in the USA was a cyclical downturn or an economic shock?
• If it was an economic shock, using an AD-AS diagram, demonstrate how the economy reached its long-run equilibrium by appropriate monetary and fiscal policy.
