The economy is currently in long-run equilibrium. If the central bank increases the money supply, in the long run the price level will raises.
<h3>What is long-run equilibrium?</h3>
The term “long-run equilibrium” is used in economics to represent a theoretical idea in which all markets are in equilibrium and all prices and quantities have fully adjusted to achieve equilibrium.
The long-run differs from the short-run, which has some limitations and markets that are not entirely balanced.
Currently, the economy is in long-run balance. If the central bank expands the money supply, the price level will rise in the long run.
Therefore, in the long run, the price level will raise as the central bank increases the money supply.
