Essay

Consider the following model Yt=α0+α1Xte+utY _ { t } = \alpha _ { 0 } + \alpha _ { 1 } X _ { t } ^ { e } + u _ { t } t
where the superscript "e" indicates expected values.This may represent an example
where consumption depended on expected, or "permanent," income.Furthermore, let
expected income be formed as follows: Xte=Xt1e+λ(Xt1Xt1e);0<λ<1X _ { t } ^ { e } = X _ { t - 1 } ^ { e } + \lambda \left( X _ { t - 1 } - X _ { t - 1 } ^ { e } \right) ; 0 < \lambda < 1 1
This particular type of expectation formation is called the "adaptive expectations
hypothesis."
(a) In the above expectation formation hypothesis, expectations are formed at the beginning of the period, say the 1st 1 ^ { \text {st } } of January if you had annual data. Give an intuitive explanation for this process.
