Which economic factor is influenced by adjustments in the overall demand for goods and services?

The correct answer pertains to fiscal policy, which is significantly influenced by adjustments in overall demand for goods and services. Fiscal policy includes government spending and taxation strategies that are implemented to manage economic fluctuations. When demand for goods and services changes, it often prompts the government to adjust its fiscal policies, such as increasing spendings to stimulate the economy or reducing taxes to enhance consumer spending. These actions aim to stabilize economic growth during downturns or control inflation during periods of rapid growth.

In contrast, monetary policy focuses on the management of money supply and interest rates typically conducted by central banks to influence economic activity. Interest rates, while affected by demand for goods and services, are primarily a tool of monetary policy. The supply chain refers to the processes and systems that deliver goods and services from production to consumption, and while it can be affected by demand changes, it does not directly influence broad economic policy decisions like fiscal strategy does.
