  • Aggregate demand for final goods consists of ex ante consumption, ex ante investment, government spending etc.
  • The rate of increase in ex ante consumption due to a unit increment in income is called marginal propensity to consume. For simplicity we assume a constant final goods price and constant rate of interest over a short run to determine the level of aggregate demand for final goods in the economy.
  • We also assume that the aggregate supply is perfectly elastic at this price. Under such circumstances, aggregate output is determined solely by the level of aggregate demand. This is known as the effective demand principle.
An increase (decrease) in autonomous spending causes aggregate output of final goods to increase (decrease) by a larger amount through the multiplier process.

Consider the following statements. 1. The rate of increase in ex ante...
Explanation:

Only statement 1 is correct. Statement 2 is incorrect.



Statement 1: The rate of increase in ex ante consumption due to a unit increment in income is called marginal propensity to consume.



The marginal propensity to consume (MPC) measures the change in consumption that occurs when income changes. It represents the proportion of additional income that is spent on consumption. In other words, it is the slope of the consumption function.



Statement 2: An increase in autonomous spending causes aggregate output of final goods to decrease by a larger amount through the multiplier process.



This statement is incorrect. An increase in autonomous spending actually leads to an increase in aggregate output of final goods through the multiplier process. The multiplier effect refers to the additional increase in aggregate output that results from an initial increase in autonomous spending. When autonomous spending increases, it stimulates additional rounds of spending, which in turn increases aggregate output. The multiplier effect amplifies the initial increase in spending, leading to a larger increase in aggregate output.



To summarize:

Statement 1 is correct. The rate of increase in ex ante consumption due to a unit increment in income is called marginal propensity to consume.

Statement 2 is incorrect. An increase in autonomous spending causes aggregate output of final goods to increase, not decrease, through the multiplier process.
