The US economy was hit two shocks at the onset of the 2008 Global Financial crisis. First, it faced a negative supply shock due to a doubling of the price of oil, large price increases in other commodities and the collapse of a domestic housing bubble. Soon after, a negative aggregate demand shock followed, as consumer optimism dropped, while a reduction in credit supply in the financial sector caused firms to cut back on their investment plans.
Using the AS/AD model and assuming that the economy is initially at its long-run equilibrium (where output is equal to Y*), show on a graph what happens in the short-run to inflation and output when the economy is hit by a negative demand shock such as a drop in consumer optimism or firm investment.
