DSE 2009 Question 53: Open-economy macroeconomics

Setup, from Q51 of the paper:

An economy is described by a goods-market equilibrium $Y=C(Y)+I(r)+G+NX(Y,e)$ and a money-market equilibrium $M/P=L(Y,r)$, with $C=\bar C+\sigma(Y-T)$, $T=\tau Y$, $I=\bar I-\delta r$, $NX=\bar X-\mu Y-\gamma e$, $L=\bar L+\alpha Y-\beta r$, and $r=\bar r$, $M=\bar M$, $P=\bar P$ fixed. Drawing IS and LM in the $(Y,e)$ plane with $Y$ horizontal and $e$ vertical. In this case

(Same model.) An increase in $\bar P$ results in
