Question: Consider the following demand function for money in the United States for the period 19801998: M t = β 1 Y β2 t r β3

Consider the following demand function for money in the United States for the period 1980€“1998:

Mt = β1 Yβ2t rβ3t eut

where M = real money demand, using the M2 definition of money
Y = real GDP
r = interest rate

To estimate the above demand for money function, you are given the data in the following table.

Observation GDP M2 CPI LTRATE TBRATE 11.27 1980 2795.6 1600.4 82.4 11.506 90.9 14.029 1981 3131.3 1756.1 13.45 1982 10.6


a. Given the data, estimate the above demand function. What are the income and interest rate elasticities of demand for money?

b. Instead of estimating the above demand function, suppose you were to fit the function (M/Y)t = α1rtα2eut. How would you interpret the results? Show the necessary calculations.
