Question 50

At lower price levels, exports increase resulting in an increase in the real GDP.

The downward slope of the aggregate demand curve can be explained by the positive relationship between lower price levels and increased exports, which in turn boosts real GDP. As prices decrease, domestic goods become more attractive to foreign buyers, leading to higher export levels and an increase in overall demand for goods and services.

A) At lower price levels, exports increase resulting in an increase in the real GDP

This statement accurately reflects the reason behind the downward slope of the aggregate demand curve. Lower price levels make domestic products cheaper for foreign consumers, leading to an increase in exports. This rise in exports contributes positively to the overall real GDP, thereby supporting the downward slope of the curve.

B) At lower price levels, real wealth decreases, resulting in a decrease in the quantities of goods and services demanded

This option is incorrect as lower price levels typically lead to an increase in real wealth, not a decrease. As prices drop, consumers can afford more goods and services, increasing demand rather than decreasing it. The assertion that wealth decreases contradicts the fundamental economic principle that lower prices can enhance purchasing power.

C) At lower price levels, imports increase resulting in an increase in the real GDP

This choice is incorrect because while lower price levels may lead to an increase in imports, this does not contribute positively to real GDP. Instead, an increase in imports can offset the increase in exports, potentially leading to a neutral or negative effect on the aggregate demand curve, as it reflects a leakage from the domestic economy.

D) At lower price levels, interest rates decrease resulting in a decrease in the quantities of goods and services demanded

This statement is misleading. Generally, lower price levels are associated with lower interest rates, which typically stimulate borrowing and increase demand for goods and services. Hence, the assertion that demand decreases is incorrect; rather, lower interest rates usually encourage spending and investment.

Conclusion

The correct answer, A, illustrates the relationship between lower price levels and increased exports, which drives real GDP growth, thereby explaining the downward slope of the aggregate demand curve. In contrast, the other options either misinterpret the effects of price levels on wealth, demand, or the relationship between imports and GDP, failing to accurately represent the economic principles at play.
