I need step by step solution to the following this question asap.I have limited time so please do it quickly with

detailed explanation

thanks in advance



4. Consider an economy whose output behaves according to
yt = a(Tt - Te )
A policy maker sets monetary policy, but inflation cannot be controlled with perfect ac-
curacy. Specifically,
Tit = Tit + nt
where , is the inflation target and 7, is a random variable such that E[n ] = 0 and
Elm-] = 02. The private sector has rational expectations and the policy-maker sets TP so
as to minimize expected loss, which is
El(yt - y)2 + X72].
Here is the timeline of events: (i) the private sector sets , (ii) the policy-maker sets TP,
(iii) the value of the shock n is revealed and inflation and output are determined.
(a) Find the rational expectations equilibrium values of expected inflation E[ ] and
expected log output Elyt] in terms of parameters.
(b) Solve for the rational expectations equilibrium values of yt and it in terms of pa-
rameters and ,. What is the predicted slope of the empirical Phillips curve
Ay ,
(c) What is the (Pearson) correlation coefficient between inflation and output?
