Why are monetary policy lags generally shorter than fiscal policy lags?

Monetary policy lags are generally shorter than fiscal policy lags because central banks can implement changes quickly through mechanisms like interest rate adjustments or open market operations, which can be executed almost immediately. In contrast, fiscal policy involves a more complex legislative process, requiring proposals to be drafted, debated, and approved by various government bodies, which can take considerable time. Additionally, the impact of monetary policy tends to be more immediate, while fiscal measures often require time to be enacted and for their effects to materialize in the economy.
