1. Assume a hypothetical economy in which the velocity is constant at 2 and real GDP is always at a constant potential of $4,000. Suppose the money supply is $1,000 in the first year, $1,100 in the second year, $1,200 in the third year, and $1,300 in the fourth year. a. Using the equation of exchange, compute the price level in each year. b. Compute the inflation rate for each year. c.
