Which of the following would shift the short-run aggregate supply (SRAS) curve to the right, ignoring any potential effect on long-run aggregate supply (LRAS)? There is a technological improvement that allows firms to reduce their costs of production permanently. O The interest rate decreases, spurring investment spending. O The government introduces a set of new regulations that make it more costly for firms to produce and sell goods and services. These regulations are expected to be permanent. O There is an increase in government spending. O The world price of oil increases rapidly without warning but is not expected to remain at the new high level permanently. However, in the short run, it is more costly for all firms to produce goods and services. The following graph shows the short-run aggregate supply (SRAS) curve and the long-run aggregate supply (LRAS) curve for an economy. Suppose the world price of oil decreases rapidly without warning but is not expected to remain at the new low level permanently. However, in the short run, it is less costly for firms to produce goods and services. Illustrate the short-run effect of this change, before any long-run adjustments have taken place, by shifting one or both of the supply curves ( SRAS and LRAS) on the following graph. If you do not believe there will be any long-term effects, leave the LRAS in its current position. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back
