Sketch the adjustment process and identify whether the market will converge to the long-run equilibrium P*Q*. Second, assume that demand is represented by D2 and that the price-quantity adjustment process starts from point a'. Sketch the adjustment process and identify whether the market will converge to the long-run equilibrium P'Q'. What factor accounts for the different outcomes under D1 and D
