The authors meticulously analyze the theoretical foundations of QE and its practical applications by central banks worldwide. They investigate the direct and indirect channels through which QE influences key macroeconomic variables, ultimately assessing its effectiveness in stimulating economic growth, managing inflation, and ensuring financial stability.
