➤ Why is the effect of interest rate changes on GDP considered macroeconomics?
Interest rates influence aggregate demand by affecting investment, consumption, and net exports. Central bank policy shifts short-term rates to stabilize output and inflation, which moves national income and GDP. Because this analysis uses economy-wide variables and models—like IS-LM, AD-AS, or aggregate supply—it belongs to macroeconomics.
