3) Why the slope of the aggregate supply curve differs in the short-run and in the long-run? Why the long- run aggregate supply curve is vertical and why the short-run supply curve is upward sloping? Explain in detail.
The economy is in long run equilibrium. Congress’s passage of new laws significantly increasing the regulation of business. It is assumed that everything else stays constant. What do we expect in aggregate demand, short run aggregate supply aggregate supply in short run?   And what happens in long run, and long run equilibrium price level and output?    Explicitly state what happens to equilibrium price level and output in both short run and long run and how economy corrects from short run to long run.
42. Suppose that there is a temporary fall in aggregate supply due to a drought. Whathappens in the long-run?(A) Higher prices cause permanent tensions, leading long-run aggregate supply to shiftleft, resulting in a lower natural rate of output.(B) Over time, as the drought conditions fade, aggregate supply rises and returns tothe original natural rate of output.(C) Aggregate demand shifts right, so that prices are higher but long-run output isunchanged.(D) If the person you’re dating enjoys Taylor Swift, dump them immediately

    11. Explain why the following statements are false.
