In-depth Notes on Economic Fluctuations and Their Management
Economic Factors Linked to Quality of Life
- Elements like welfare, standard of living, longevity, access to education, and healthcare impact overall quality of life.
Long Run vs Short Run
- In the long run:
- Money doesn't matter;
- Key components are population, capital, and technology.
- Keynes' Perspective:
- Keynes (John Maynard Keynes) highlighted that people are ‘dead’ in the long run, implying that attention should be given to short-term economic management and interventions.
- Important for government to play an active role in managing economic fluctuations.
Recession and Its Effects
- A recession is defined as a period of declining economic activity.
- Real incomes can fall when inflation exceeds wage growth.
- The National Bureau of Economic Research (NBER) designates recessions.
- Not all individuals experience recessions equally; personal circumstances vary.
GDP and Economic Performance
- Real GDP growth is expected to be around 1.75% per year, reflecting long-term potential GDP driven by labor, capital, natural resources, and technology.
- Fluctuations typically exist around this potential GDP, indicating periods of over or under production.
- Overproduction can lead to lower unemployment than the natural rate, while underproduction leads to economic instability.
Business Cycle Characteristics
- Economic fluctuations are irregular and unpredictable, corresponding to changes in business conditions.
- Business cycles vary in length and intensity.
- Economic variables such as real GDP, unemployment, and real investment often correlate with business cycle phases.
Investment during Recessions and Expansions
- Observations from Arthur Mernsback (former Fed Chair): During recessions, investment falls, unemployment rises, and real GDP declines.
- In expansions, the reverse is true: investments increase, unemployment falls, and GDP rise.
Short Run and Long Run Economic Variability
- In the short run, changes in nominal variables (like wages and prices) can lead to real economic fluctuations.
- Classical dichotomy emphasizes the separation of real (like GDP) and nominal variables (like inflation).
- In the short run, real and nominal variables are intertwined, and the money supply can impact economic performance.
Aggregate Demand and Supply Model
- The AE model is used to analyze economic fluctuations, impacting inflation, output, and unemployment.
- The Aggregate Demand (AD) curve has a downward slope because of phenomena such as the wealth effect and interest rate effect.
Wealth Effect
- A decrease in price level raises the real value of money, encouraging higher consumption as purchasing power increases.
- Consumers feel wealthier which drives demand.
Interest Rate Effect
- Lower price levels reduce the demand for money, leading to increased savings and lower interest rates.
- Lower interest rates encourage borrowing and investment, stimulating economic growth.
Implications of Economic Fluctuations
- Expansionary periods tend to drive inflation, as increased demand puts upward pressure on prices.
- Economic expansions can be sustainable to a point; beyond that, inflation can become problematic, leading to cycles of job loss and output decrease.
Government Role in Managing Economic Fluctuations
- The Federal Reserve aims for maximum employment at natural rates and stable prices.
- Tools include monetary policy interventions to smooth out these fluctuations and minimize adverse social impacts.
