a measure of total expenditures at current prices. 不是档期价格下所有的支出？GDP=支出吗

问题如下：

The most accurate description of nominal GDP is:

选项：

a measure of total expenditures at current prices.

the value of goods and services at constant prices.

a measure to compare one nation's economy to another.

解释：

A is correct.

Nominal GDP is defined as the value of goods and services measured at current prices. Expenditure is used synonymously with the value of goods and services since aggregate expenditures must equal aggregate output of an economy.

考点：GDP定义

解析：注意到GDP的衡量使用当期的市场价值而非基期的价值，所以本题只有A选项符合条件，B选项不选。

真实GDP更适合用于比较两国的经济发展情况，因为它剔除了通货膨胀的影响。C选项不入选。
