单选题 Which of the following events is most likely to increase short-run aggregate supply (shift the curve to the right)? A. High unemployment puts downward pressure on money wages. B. A rise in resource prices. C. Inflation that results in an increase in goods prices.

【正确答案】 A

【答案解析】The short-run aggregate supply curve is constructed for a given level of money wages and other resource prices. Falling money wages would cause businesses to increase (profit maximizing ) output levels at each price level for final goods and services. Changes in the price level of goods and services are represented by a movement along a short-run aggregate supply curve, not a shift in the curve. A rise in resource prices will decrease aggregate supply. An increase in government spending will shift the aggregate demand curve but not the aggregate supply curve.
