ountry are similar.
If PPPs were used, it is most likely that B's output per head would seem closer than it does using exchange rates.

(5 points)
The slope of the consumption function at any level of YDIS shows the value of MPCDIS at that level of YDIS.

Which of the following is a shortcoming of the simple multiplier model that the AS-AD model overcomes?
1. The multiplier model ignores the fact that a rise in planned spending which causes a rise in output will also lead to a rise in incomes and the demand for money, and so in turn lead to a rise in the interest rate. 2. The multiplier model ignores the fact that a rise in injections leads to a rise in prices which will cause people to reduce their spending plans. (6 points)
