Some simplifying help.
Are you able to help me to simplify this?

$\Pi_t = 0.5 \Pi_t + 0.5 \Pi_{t-1} - 1.5(u_t-u_n)$

Im finding it quite difficult, what i have so far is this.

$0.5\Pi_t=0.5\Pi_{t-1}-1.5(u_t-u_n)$

Im not sure if thats right. I need it in terms of $\Pi_t$
Preferably in a full unit of it.

Thanks.

What information do you have for $\Pi_t$, $\Pi_{t-1}$, $u_t$, and $u_n$? What is meant by "a full unit of" $\Pi_t$?

Thank you! (Wink)
