Study Notes
Money Growth and Inflation
- Inflation is characterized by a general increase in prices, while deflation indicates a decrease in price levels.
- Hyperinflation refers to extremely high inflation rates, exemplified by Zimbabwe's inflation reaching 24,000% in February 2008.
Classical Theory of Inflation
- The quantity theory of money, a classical economic principle, focuses on long-run determinants of price levels and inflation rates.
- Two perspectives on the economy's overall price level are the level of prices and the value of money.
Money Supply, Demand, and Equilibrium
- The value of money is influenced by its supply and demand in the economy.
- Understanding the determinants of money supply and demand is crucial for establishing monetary equilibrium.
Effects of Monetary Injection
- A significant increase in money supply, such as doubling it, leads to changes in the equilibrium price level.
- The quantity theory posits that the money supply is the main driver of inflation, encapsulated in Milton Friedman's assertion that inflation is fundamentally a monetary phenomenon.
Classical Dichotomy and Monetary Neutrality
- Monetary changes affect nominal variables (measured in monetary units) and not real variables (measured in physical units), highlighting the classical dichotomy.
- Monetary neutrality implies that changes in the money supply do not affect real economic outcomes, such as production or employment.
Velocity and the Quantity Equation
- The velocity of money is the rate at which money circulates within the economy.
- The quantity equation is expressed as M × V = P × Y, connecting the money supply (M) and money velocity (V) to the nominal value of output (P × Y).
The Fisher Effect
- An increase in money growth leads to a higher inflation rate without affecting real variables, due to the principle of monetary neutrality.
- The Fisher effect describes the one-for-one adjustment of nominal interest rates to inflation rates, resulting in both higher inflation and nominal interest in the long run.
Costs of Inflation
- Inflation can lead to reduced purchasing power, a concept known as the inflation fallacy.
- Additional costs associated with inflation include shoeleather costs (the cost of reducing cash holdings) and menu costs (the costs related to changing prices).
