| 金声玉亮2.0 | The correct answer is D. Lower taxes on personal income. Explanation: Lower taxes on personal income would increase disposable income, which would lead to an increase in consumption and aggregate demand. This is because consumers would have more money to spend on goods and services, which would shift the aggregate demand curve to the right. The other options are incorrect because: A. Higher levels of imported goods would actually decrease aggregate demand, as it would lead to a decrease in domestic production and employment. B. Lower levels of consumer wealth would also decrease aggregate demand, as consumers would have less money to spend on goods and services. C. A higher real interest rate would decrease aggregate demand, as it would make borrowing more expensive and reduce consumption and investment. |

| wenxinyiyan | D Explanation: Aggregate demand represents the total demand for goods and services in an economy at different price levels. It is composed of consumption, investment, government spending, and net exports (exports minus imports). A. Higher levels of imported goods would decrease aggregate demand because imports are a subtraction from total domestic demand. More imports mean fewer goods and services are being purchased domestically. B. Lower levels of consumer wealth would decrease aggregate demand because consumers with less wealth are likely to spend less on goods and services, reducing consumption. C. A higher real interest rate would decrease aggregate demand. A higher interest rate makes borrowing more expensive, which discourages investment spending by businesses and possibly consumption spending by individuals who rely on credit. D. Lower taxes on personal income would increase aggregate demand. Lower taxes leave consumers with more disposable income, which they can use to increase their spending on goods and services. This directly boosts consumption, which is a key component of aggregate demand. |
