I need solution 3, 5, and 6 ...

3. Consider two countries. A and B. In A new technologies (eg., mobile payment apps and cryptocur- rencies) have been enthusiastically adopted by the population, thereby reducing the proportion of income that is held as real money balances. Over this period, no such changes occurred in B. If the rate of money growth and the growth rate of real GDP were the same in A and B over this period, then how would the rate of inflation differ between the two countries? (10 points) 4. If the demand for money depends positively on real income and depends inversely on the nominal interest rate, what will happen to the price level today if the central bank credibly announces that it will decrease the money growth rate in the future, but it does not change the money supply today? (10 points) 5. Between 1970 and 1995, the number of yen required to buy one dollar declined dramatically (see Figure 1). What must be true about the price levels in Japan versus the United States according to the law of one price? (10 points) 6. Explain whether each of the following changes in the composition of the labor force is likely to affect frictional or structural unemployment and increase or decrease the measured natural rate of unemployment. (a) A "baby boom" causes an increase in the share of young workers (age 16-21) as a percentage of the labor force. (5 points) (b) A loosening of federal restrictions on eligibility for disability benefits leads to an increase in the number of people receiving disability payments. (5 points) 3.
