In explaining the downward slope of the aggregate demand curve, the interest rate effect suggests that a higher price level will:
选项：
A.lead to lower interest rates, which will lead to higher levels of consumption and investment. B.lead to higher interest rates, which will lead to lower levels of consumption and investment. C.not affect interest rates and therefore will lead to a higher level of aggregate demand.解释：
B is correct. Given the fixed money supply, a higher price level leads to a higher money price.Since the interest rate is the price of money, as the price level rises, so will the interest rate.Consumption and investment fall as interest rates rise
Since the interest rate is the price of money, as the price level rises, so will the interest rate。这个逻辑不太理解，看能否解释下，为什么高物价会导致高利率？
