C. Interest rates are exclusively determined by the demand and supply of money.
D. Fiscal deficits are the sole cause of structural unemployment.
💡 Solution & Explanation
Irving Fisher formulated the Quantity Theory of Money through the equation of exchange, establishing that money supply changes have a direct proportional effect on the price level when velocity and output remain constant. Alternative economic theories focus on interest rates or fiscal imbalances rather than this monetary identity. This relationship forms the cornerstone of classical macroeconomic monetary analysis.
