Transmission mechanism shows:

Question

Accepted Answer

The correct option is 2:

The transmission mechanism in economics, particularly in macroeconomics and monetary policy, refers to the process through which changes in the money market (controlled primarily by the central bank through interest rates or money supply) influence the real economy, specifically the goods market (aggregate demand, output, employment, and inflation). Essentially, it explains the cause-and-effect chain: a monetary policy action (like cutting interest rates) first affects financial conditions (the money market) which then alters investment, consumption, and net exports, ultimately changing aggregate demand and output in the goods market. Thus, the mechanism is the link or relationship that transmits signals from the monetary side to the real side of the economy.

The incorrect option is 1:
The relationship between income and saving is generally described by the saving function, which is a component of basic Keynesian economics, but it is not the definition of the transmission mechanism. This relationship is a direct behavioral response within the goods market itself, showing how households allocate their income, not the process of monetary policy impacting the real economy.

The incorrect option is 3:
The relationship between income and consumption is known as the consumption function (or Propensity to Consume). Like the saving function, this relationship is a fundamental behavioral equation that determines aggregate demand within the goods market, and while consumption is affected by the transmission mechanism, this specific relationship is only one segment of the overall mechanism, not the mechanism itself.

The incorrect option is 4:
Since Option 2 accurately describes the core concept of the transmission mechanism—linking monetary policy decisions in the money market to outcomes in the real goods market—this option is clearly incorrect.
