What is the typical outcome of increased government expenditure according to the Keynesian multiplier effect?

The rationale behind the typical outcome of increased government expenditure, particularly according to the Keynesian multiplier effect, revolves around the impact of government spending on aggregate demand and overall economic activity. When the government increases its expenditures, it directly injects money into the economy. This initial spending stimulates demand for goods and services.

As businesses begin to respond to this increased demand, they may increase production, which often leads to more hiring and higher wages. The individuals who are employed as a result of this increase in production now have more income to spend, further propelling economic activity. This process continues because the initial increase in government spending creates a ripple effect throughout the economy.

The Keynesian multiplier quantifies this effect and indicates that the total increase in economic output will be greater than the initial amount of government spending, as it generates successive rounds of spending. Thus, the typical outcome of increased government expenditure is a greater increase in overall economic output, aligning with option C, which highlights the expansive impact of the multiplier effect in stimulating economic growth.
