Suppose the money supply $M$has been growing at $10\%$per year, and nominal GDP, $PY$, has been growing at $20\%$per year. The data are as follows (in billions of dollars):

Calculate the velocity for each year. At what rate is the velocity growing?

Calculate what happens to nominal GDP if velocity remains constant at $4$and the money supply increases from $\backslash (250$billion to$\backslash )375$ billion.

What happens to nominal GDP if the money supply grows by $17\%$ but velocity declines by $24\%$?

If velocity and aggregate output remain constant at $5$and $\backslash (1,000$billion, respectively, what happens to the price level if the money supply declines from $\backslash )400$ billion to$\$300$ billion?

Suppose the liquidity preference function is given by

$L\left(i,Y\right)=\frac{Y}{8}-1,000i$

Use the money demand equation, along with the following table of values, to calculate the velocity for each period.

鈥淭he appreciation of the dollar from 2012 to 2017 had a negative effect on aggregate demand in the United States.鈥� Is this statement true, false, or uncertain? Explain your answer.

If credit cards were made illegal by congressional legislation, what would happen to velocity? Explain your answer.

In many countries around the world, the population is aging and large segments of the population are retiring or close to retirement. What effect would this have on a country鈥檚 long-run aggregate supply curve? What will happen to aggregate output as a result?

鈥淚f nominal GDP rises, velocity must rise.鈥� Is this statement true, false, or uncertain? Explain your answer.

Why would a central bank be concerned about persistent, long-term budget deficits?
