问题如下：
Which statement regarding fiscal deficits is most accurate?
选项：
A.Higher government spending may lead to higher interest rates and lower private sector investing.
B.Central bank actions that grow the money supply to address deflationary conditions decrease fiscal deficits.
C.According to the Ricardian equivalence, deficits have a multiplicative effect on consumer spending.
解释：
A is correct.
Government borrowing may compete with private sector borrowing for investment purposes.
考点： fiscal deficits
解析：政府支出会产生财政赤字，进而抬升市场利率，打击私人部门投资的积极性，这便是产生挤出效应。所以A选项错误。
面对通缩特别是流动性陷阱的状况，央行靠印发货币是解决不了问题的，正确的做法是采用量化宽松的手段。所以B选项正确。
C选项打酱油的选项。李嘉图均和乘数效应是两个不同的概念。错误。
和利率相关的不都一般是monetary policy吗？
