Use the IS-LM model to analyze the effects of

1. a housing market crash that reduces consumers' wealth (This is a shock to the IS)
2. consumers using cash in transactions more frequently in response to an increase in identity theft (This is a shock to the LM)

For each shock,

1. use the IS-LM diagram to determine the effects on Y and r.
2. figure out what happens to C, I, and the unemployment rate.
