| 金声玉亮2.0 | B. Business firms expect lower sales in the future. Explanation: A decrease in business confidence, such as expecting lower sales in the future, would lead to a decrease in investment spending, which would shift the aggregate demand curve to the left. Note: Aggregate demand curve shifts to the left when there is a decrease in consumption, investment, government spending, or net exports. The other options are incorrect because: A. An increase in consumer confidence would shift the aggregate demand curve to the right, as consumers would be more likely to spend. C. If foreigners develop a preference for our products, it would lead to an increase in net exports, shifting the aggregate demand curve to the right. D. An increase in government spending would also shift the aggregate demand curve to the right. |

| wenxinyiyan | B Explanation: The aggregate demand curve represents the total demand for goods and services in an economy at different price levels. When the curve shifts to the left, it means that there is a decrease in aggregate demand at each price level. A. An increase in consumer confidence typically leads to higher consumption and thus, higher aggregate demand. This would shift the aggregate demand curve to the right, not the left. B. If business firms expect lower sales in the future, they are likely to reduce investment spending. Lower investment spending would lead to a decrease in aggregate demand, shifting the aggregate demand curve to the left. C. Foreigners developing a preference for our products would increase exports, which is a component of aggregate demand. This would shift the aggregate demand curve to the right. D. An increase in government spending directly increases aggregate demand. This would also shift the aggregate demand curve to the right. |
