| wenxinyiyan | B Explanation: Contractionary monetary policy refers to the actions taken by a central bank to reduce the money supply in an economy, often with the goal of reducing inflation or stabilizing currency values. A. The purchase of bonds by the central bank is an expansionary monetary policy because it increases the money supply in the economy. When the central bank purchases bonds, it pays with newly created money, which enters the economy. B. The sale of bonds by the central bank is a contractionary monetary policy. When the central bank sells bonds, it removes money from the economy as people pay for the bonds with their existing money. This reduces the money supply. C. An increase in taxes is a fiscal policy measure, not a monetary policy measure. Fiscal policy refers to government spending and tax decisions. While an increase in taxes can reduce consumption and thus economic activity, it does not directly affect the money supply, which is the focus of monetary policy. D. An increase in government spending is also a fiscal policy measure. It typically stimulates the economy by increasing demand but, like taxes, does not directly impact the money supply. |
