When planned investment surpasses planned savings, the economy experiences excess demand. This triggers several positive economic effects:
Increased Aggregate Demand: Higher investment boosts spending and demand for goods and services, prompting producers to increase output.
Output and Income Growth: Firms expand production to meet demand, leading to higher output and household income.
Job Creation: Rising output increases the demand for labor, creating jobs and lowering unemployment.
Multiplier Effect: The initial investment increase initiates a multiplier effect, causing further increases in demand, output, and employment through successive rounds of income and consumption.
Equilibrium Re-establishment: As income rises, savings also increase. Eventually, savings rise to match the higher investment level, restoring economic equilibrium.
Therefore, when planned investment exceeds planned savings, it results in a cumulative rise in output, income, and employment, ultimately leading to a new equilibrium.
