Assuming Okun's law $is$ given $byU-U_n=-0\mathrm{.}75(Y-Y^p)$ and that the Phillips curve $is$ given

$by={}^e-0\mathrm{.}6(U-U_n)+,$

$a.$ Obtain the short$-$run aggregate supply curve $if$ expectations are adaptive, inflation was

$3\%$ last year, and potential output $is$ $$10=0$ $$8,$$$10,$ and $$12$ trillion and plot the short$-$run

aggregate supply curve

$c.If$ a trade war increases prices $by1$ percentage point, what would happen $to$ the short$-$run

aggregate supply curve you've drawn $in(b)?$
