Macroeconomics and Monetary Theory Flashcards

Flashcards covering key vocabulary and concepts from macroeconomics, focus on monetary policy, inflation, and the classical dichotomy as presented in the lecture notes.

Classical Dichotomy

The theoretical separation of nominal variables and real variables.

Nominal Variables

Economic variables measured in monetary units, such as prices and dollar wages.

Real Variables

Economic variables measured in physical units, such as relative prices, real GDP, and real interest rates.

Money Neutrality

The proposition that changes in the money supply do not affect real variables.

Velocity of Money

The rate at which money changes hands; calculated as $\text{V} = \frac{\text{P} \times \text{Y}}{\text{M}}$, where $\text{P}$ is the price level, $\text{Y}$ is real output, and $\text{M}$ is the quantity of money.

Quantity Equation

The mathematical identity $\text{M} \times \text{V} = \text{P} \times \text{Y}$, which relates the quantity of money to the nominal value of output.

Inflation Tax

The revenue the government raises by creating money, which acts like a tax on everyone who holds money.

Fisher Effect

The one-for-one adjustment of the nominal interest rate to the inflation rate, expressed as $\text{Nominal Interest Rate} = \text{Real Interest Rate} + \text{Inflation Rate}$.

Shoeleather Costs

The resources wasted when inflation encourages people to reduce their money holdings, such as the time and effort of making more frequent trips to the bank.

Menu Costs

The costs associated with changing prices, such as reprinting catalogs or updating price tags.

Relative-Price Variability

A distortion caused by inflation where prices do not move in sync, leading to a misallocation of resources because consumer decisions are based on distorted relative prices.

Inflation-Induced Tax Distortions

The tendency of inflation to raise the tax burden on income earned from savings, which can discourage long-term economic growth.

Confusion and Inconvenience

The loss of money's reliability as a yardstick of value due to changing price levels caused by inflation.

Arbitrary Redistributions of Wealth

The process by which unexpected inflation redistributes wealth between debtors and creditors, or between employers and employees.

Hyperinflation

An extraordinarily high rate of inflation, typically exceeding $50\%$ per month.
