The branch of economics that studies the behavior and decisions of individual agents, such as households and firms.

Short-Run Aggregate Supply

The total supply of goods and services that firms are willing and able to produce in the short run, taking into account the current price level and input prices.

Long-Run Aggregate Supply

The total supply of goods and services that firms are willing and able to produce in the long run, when all input prices have fully adjusted to changes in the price level.

Equilibrium

The state in which aggregate demand equals aggregate supply, resulting in a stable price level and level of output.

Fiscal Policy

The use of government spending and taxation to influence the economy, particularly aggregate demand.

Monetary Policy

The use of monetary tools, such as interest rates and the money supply, to influence the economy, particularly aggregate demand.

Open Economy

Stabilization Policies

Ceteris Paribus

A Latin phrase meaning 'all other things being equal,' used in economics to isolate the effect of a single variable on an outcome.

Multiplier Effect

The idea that an initial change in spending can lead to a larger change in aggregate demand and output through a chain reaction of increased spending.

Okun's Law

An empirical relationship between the unemployment rate and the output gap in an economy, suggesting that for every 1% increase in the unemployment rate, there is a 2% decrease in the output gap.

Sticky Wages

The phenomenon in which wages do not adjust immediately to changes in the price level, leading to short-run fluctuations in employment and output.

Sticky Prices

The phenomenon in which prices do not adjust immediately to changes in the price level, leading to short-run fluctuations in output and inflation.

Natural Rate of Unemployment

The rate of unemployment that exists when the economy is at full employment, consisting of frictional and structural unemployment.

Multiplier

The ratio of the change in output to the initial change in spending, indicating the magnifying effect of changes in spending on aggregate demand and output.

Marginal Propensity to Consume

Marginal Propensity to Save

The fraction of additional income that is saved, indicating the responsiveness of saving to changes in income.

Expansionary Fiscal Policy

Government policies that increase government spending or reduce taxes to stimulate aggregate demand and promote economic growth.

Contractionary Fiscal Policy

Government policies that decrease government spending or increase taxes to reduce aggregate demand and control inflation.

Expansionary Monetary Policy

Exchange Rate

The price of one currency in terms of another currency, determining the cost of goods and services in international trade.

Net Exports

The difference between a country's exports and imports, indicating the net flow of goods and services in international trade.

Economic Indicators

The total value of all final goods and services produced within a country's borders in a given time period, usually a year.

Inflation Rate

The percentage increase in the general price level of goods and services in an economy over a given time period.

Unemployment Rate

The percentage of the labor force that is unemployed and actively seeking employment.

Business Cycle

The recurring pattern of expansion and contraction in an economy, consisting of periods of economic growth and recession.

Recession
