What is The Short-Run and Long-Run Phillips Curves?
What is stagflation? How may it affect the Phillips Curve? What policy measures may be taken to reduce stagflation?
I can't find anything to back up that a decrease in aggregate demand causes cost push inflation. My textbook does mention the increase in aggregate supply. I thought that a decrease in price generally meant deflation? And doesn't the decrease (left shift) in aggregate demand result in lower prices?

- Hi, could you help me solve this problem? Consider an increase in global oil and gas prices from the point of the euro area (that does not produce much oil or gas itself).

Starting from a long-run equilibrium, illustrate the effects of these two changes on aggregate supply and aggregate demand on the following graph. Then, on the subsequent graph, indicate what happens on a Phillips-curve diagram.
