Money is,useless until we get rid of it. But money is anything but useless from a macroeconomic point of view, In this and the following chapter, we will see that monetary policy is today the most important tool that the government has to the business cycle. The central bank uses its control over the supply of money to stimulate the economy when unemployment begins to rise or to brake the economy when prices rise too quickly. When money is well managed. as was the case for the United States in the 1990s, output grows smoothly with stable prices. But an unreliable monetary system. such as that seen in unstable Russia over the last decade, can lead to inflation or depression. Many of the world’s most devastating macroeconomic problems of the twentieth century can be traced to malfunctioning money systems.
