Suppose expected inflation rate ($\pi^e_t$) of an individual is formed as:
$\pi^{e}_t = (1 − \theta) \overline{\pi} + \theta \pi_{𝑡−1}$
where, $\overline{\pi} $ is constant inflation rate, $\pi_{t−1}$ is previous year’s inflation rate, and $ 0 \leq \theta \leq 1$ is weight assigned to inflation rate at different points in time.
Then, which of the following is NOT CORRECT?
