How does expansionary monetary policy affect the economy in theory?
ANSWER-
An expansionary monetary policy is used to increase economic growth, and generally decreases unemployment and increases inflation.
Monetary policy is referred to as either being expansionary or contractionary. Expansionary policy seeks to accelerate economic growth, while contractionary policy seeks to restrict it. Expansionary policy is traditionally used to try to combat unemployment in a recession by lowering interest rates in the hope that easy credit will entice businesses into expanding. This is done by increasing the money supply available in the economy.
Expansionary policy attempts to promote aggregate demand growth. As you may remember, aggregate demand is the sum of private consumption, investment, government spending and imports. Monetary policy focuses on the first two elements. By increasing the amount of money in the economy, the central bank encourages private consumption. Increasing the money supply also decreases the interest rate, which encourages lending and investment. The increase in consumption and investment leads to a higher aggregate demand.
It is important for policymakers to make credible announcements. If private agents (consumers and firms) believe that policymakers are committed to growing the economy, the agents will anticipate future prices to be higher than they would be otherwise. The private agents will then adjust their long-term plans accordingly, such as by taking out loans to invest in their business. But if the agents believe that the central bank’s actions are short-term, they will not alter their actions and the effect of the expansionary policy will be minimized.
