Suppose​ England's economy is in​ long-run equilibrium. As a result of the​ coronavirus, the British government orders all​ non-essential businesses to close and issue​ “shutter in” and other​ “stay at​ home” directives requiring its citizens and residents not to leave their residences absent emergencies​ and/or to purchase food and groceries from markets​ (that is, people​ cannot, for​ example, go to​ restaurants, movies or sporting events and the​ like.)

The following graph shows the short-run and long-run aggregate supply curves (SRAS and LRAS) for an economy. Suppose there is a technological improvement that allows firms to reduce their costs of production permanently. Drag one or both of the curves on the graph to illustrate the long-term effects of this change. If you don't believe there will be any long-term effects, leave the curves where they are. 240 LRAS SRAS 200 SRAS 160 LRAS 120 80 40 6 12 18 24 REAL GDP (Trillions of dollars) Assuming aggregate demand is not affected by the technological improvement, the long-run effect of this v supply shock is v in aggregate output and v in the price level.
