Final answer:
Monetary policy primarily aims to maintain low and stable inflation, minimize exchange rate risks, and promote employment and economic growth, with central banks often using the federal funds rate as a policy target.
Step-by-step explanation:
Goals of Monetary Policy
The primary goals of monetary policy include maintaining low and stable inflation, minimizing the risk of exchange rate fluctuations, and fostering conditions that lead to high levels of employment and economic growth. However, these goals can sometimes conflict with each other, as measures to stimulate the economy and reduce unemployment might lead to higher inflation, while efforts to curb inflation can suppress growth and increase unemployment.
According to the neoclassical model of economics that most central bankers follow, the aggregate supply curve is vertical at the level of potential GDP, meaning that monetary policy's effect on real GDP and unemployment is limited in the long term.
As such, central bankers often focus on keeping inflation low, as this creates a better climate for a healthy and growing economy by allowing businesses to concentrate on real economic decisions instead of worrying about inflation.
Choosing appropriate targets for monetary policy, like interest rates, money growth rates, or the price level, is crucial as it determines the focus and actions of a central bank.
Historically, the Federal Reserve, for example, has used the federal funds rate as a key target to influence the economy.
