这道题LM对的吧是往左shift对吗

问题如下：

An increase in the price level would shift the:

选项：

IS curve.

LM curve.

aggregate demand curve.

解释：

B is correct.

The LM curve represents combinations of income and the interest rate at which the demand for real money balances equals the supply. For a given nominal money supply, an increase in the price level implies a decrease in the real money supply. To decrease the demand for real money balances, either the interest must increase or income must decrease. Therefore, at each level of the interest rate, income (= expenditure) must decrease—a leftward shift of the LM curve.

考点：AD曲线

解析：由于价格P是AD曲线中的自变量，当价格水平发生变化后，AD曲线的变化表现为曲线上的点沿着曲线改变，而非曲线本身的平移。

由于价格P是LM曲线中的外生变量，所以当价格水平发生变化后，LM曲线的变化表现为曲线本身的平移 ，而非曲线上的点沿着曲线改变。
