Study Notes
Classical Macroeconomic Model
- The interest rate adjusts to maintain economic equilibrium when leakages differ from injections.
- An increase in loanable funds demand leads to a higher quantity of funds loaned and elevated interest rates.
Keynesian Macroeconomic Model
- Consumption is influenced by three factors: autonomous consumption, marginal propensity to consume (MPC), and income.
- Intended investment levels reflect investors' optimism or pessimism about the economy.
- The marginal propensity to consume is crucial in calculating the multiplier effect.
- Aggregate demand (in no government or foreign trade contexts) comprises consumption plus intended investment.
Savings and Investment
- In scenarios of insufficient aggregate demand, household savings outstrip intended investment.
- If intended business investment decreases, the Keynesian multiplier effect suggests total income will drop by a greater amount.
Marginal Propensity to Save
- If Jane's income rises from $30,000 to $35,000 and her consumption increases from $26,000 to $29,000, her marginal propensity to save is 0.4.
Interest Rates and Savings
- The relationship between interest rates and savings within the Keynesian model is ambiguous; higher interest rates could result in either increased or decreased savings.
Misconceptions in Keynesian Economics
- Counter to some beliefs, interest rates do not primarily determine household saving rates.
- Wage rate adjustments do not ensure macroeconomic equilibrium in response to unequal injections and leakages.
- The presence of massive unemployment does not exclude the possibility of economic equilibrium in the Keynesian framework.
- Inflation rate is not seen as a key determinant of business investment levels.
Historical Context
- During the Great Depression, US unemployment rates soared above 20%, highlighting severe economic distress.
Key Truths and Falsehoods
- Aggregate demand is more complex than merely summing consumption and income, as indicated by false statements regarding this relationship.
- It is incorrect to assume economic downturns typically lead to increased inflation; rather, the opposite holds true in most cases.
