Consider the following four demand functions for money:
InM; = dp a,lny; + C,ln R + &;ln P + 0
InM; = Bo BlnY , Bz In R B; In P + u,
Where M;" Y", R and
denote, respectively, aggregate nominal money demand,
aggregate national income, long-term interest rate, and implicit price deflator.
These two money demand equations are estimated for the period [1949-1965] and the following estimated equations are obtained:
InM;" = 3.999 + 1.710lny" + 0.608ln R + 0.759ln P
R' = 0.942. SSR = 0.080
(1.801) (0.416) (0.469) (0.651)
InM;" = 3.999 + 1.710lnY; + 0.608ln R + 0.951ln P
R' = 0.942. SSR = 0.080
(1.801) (0.416) (0.469) (0.651)
Based on the above information,
Winc and (2) is the coefficient of In P
Rdo
Explain why the only difference between.
