Solutions

Expert Solution

A) A stock market crash reduces people’s wealth. It will result in less disposable income into hands and will shift the AD curve to the left. As a result output and price level falls in the short run.

So,:

aggregate demand shifts to left,

output falls, and

price level falls.

B) The spread of democracy around the world increases consumer confidence in the US. This will lead to an increase in exports and investments as well. There is an inflow of capital which creates a threat for the US currency.

But in the short run the result is:

Aggregate demand shifts to right,

price level increases and

output level increases

C) The European economy crashes will actually only impact demand, so the supply shift would not shift. Aggregate demand shift leftwards and as a result the price level falls and the output level will fall.

D) The US increasing military spending is an increase in government spending, thus an increase in GDP. So demand would shift to the right, output would rise, and price levels would rise.

1. Using the AS-AD model diagram, illustrate what happens to the LONG-RUN and SHORT-RUN equilibrium level of aggregate output and inflation, when the economy is hit by a negative (adverse) demand shock and there is NO POLICY response.

Will the negative demand shock more likely lead to an expansion or recession in the...
