The table below contains the following variables, growth rates
of real GDP, M1, M2, velocity of M1 and M2 (denoted V1 and V2), the
federal funds rate (FFR), and the CPI inflation rate. Use the
quantity equation to calculate the equilibrium inflation rate using
individually M1 and M2. Next, calculate the equilibrium inflation
rate assuming the quantity theory of money holds (i.e. assuming
velocity is constant). According to your calculations, which is a
better predictor of inflation, M1 or M2? Similarly, which is a
better predictor of inflation, assuming the quantity theory holds,
or not?

According to Quantity Equation: Mt * Vt = Pt * Yt
taking log the two sides, we get: LogMt + Log Vt = logPt + LogYt
taking partial derivatives on the two sides w.r.t. to time, we get:
(1/Mt)(dMt/dt) + (1/Vt)(dVt/dt) = (1/Pt)(dPt/dt) + (1/Yt)(dYt/dt)
or on the other hand gm + gv= π+ gy
where g speak to development rate of individual variables, and π is the balance inflation rate. Along these lines,
π = gm + gv - gy

According to Quantity Theory of Money: Mt * V = Pt * Yt
taking log the two sides, we get: LogMt + Log V = logPt + LogYt
taking partial derivatives on the two sides w.r.t. to time, we get:
(1/Mt)(dMt/dt) + (1/Vt)(dV/dt) = (1/Pt)(dPt/dt) + (1/Yt)(dYt/dt)
or on the other hand gm + gv= π+ gy, in any case, gv = 0 since speed is constant
where g speak to development rate of individual variables, and π is the balance inflation rate. Consequently,
π = gm - gy

According to the calculation M2 is better indicator of Inflation rate because M2 is a broader measure of cash flexibly as it contains all components of M1 along with saving stores and the momentary mutual reserve stores and time stores that can be easily changed over to fluid cash.
