The interaction of aggregate supply and aggregate demand primarily results in the levels of the following:
-
Income: Changes in the aggregate demand and supply can influence overall economic income within a country.
-
Output: The equilibrium level of output is determined by the intersection of aggregate supply and aggregate demand.
-
Employment: Aggregate demand and supply also impact levels of employment in the economy, as higher output generally requires more labor.
Checkable deposits and reserves are more related to the banking system and monetary policy, rather than directly determined by the aggregate supply and demand framework.
Therefore, the correct options are:
- Income
- Output
- Employment
