Economics

The study of how individuals, businesses, and governments make decisions about allocating scarce resources.

Microeconomics

The branch of economics that studies individual consumers, businesses, and specific markets (the small picture).

Macroeconomics

The branch of economics that studies the economy as a whole, focusing on nationwide aggregates such as GDP, inflation, unemployment, and economic growth (the big picture).

Incentive

Positive Incentive

An incentive that encourages action by rewarding someone for doing something, such as a bonus or a scholarship.

Negative Incentive

An incentive that discourages action by introducing a penalty or cost, such as a fine, late fee, or speeding ticket.

Exogenous Factors

Variables that originate outside an economic model and are taken as given, such as an unexpected natural disaster affecting supply.

Production Possibilities Frontier (PPF)

A graphical model showing the maximum combinations of two goods or services an economy can produce given available resources and technology.

Law of Increasing Opportunity Cost

The economic principle stating that as production of a good expands, the opportunity cost of producing additional units rises because resources are not equally suited to producing all goods, leading to a bowed-out PPF.

Specialization

Quantity Demanded

The specific amount of a good or service that consumers are willing and able to purchase at a given price during a specific period.

Law of Demand

The economic law stating that, all else equal ($ceteris\text{ }paribus$), an increase in price causes a decrease in quantity demanded, producing a downward-sloping demand curve.

Normal Good

A good for which demand increases when consumer income rises, and demand decreases when consumer income falls.

Inferior Good

A good for which demand decreases when consumer income rises, and demand increases when consumer income falls.

Substitutes

Pairs of goods where an increase in the price of one leads to an increase in the demand for the other (such as coffee and tea).

Complements

Pairs of goods that are consumed together, such that an increase in the price of one leads to a decrease in the demand for the other.

Subsidy

A financial transfer or assistance payment from the government to producers or consumers that effectively lowers production costs and shifts market supply outward.

Quantity Supplied

The specific amount of a good or service that producers are willing and able to sell at a particular price.

Law of Supply

The economic principle stating that, all else equal ($ceteris\text{ }paribus$), an increase in price causes an increase in quantity supplied, producing an upward-sloping supply curve.

Market Equilibrium

The state where quantity demanded equals quantity supplied ($Q_d = Q_s$), establishing an equilibrium price with no market pressure to change.

Shortage

A market disequilibrium condition where quantity demanded exceeds quantity supplied ($Q_d > Q_s$), exerting upward pressure on the price.

Surplus

A market disequilibrium condition where quantity supplied exceeds quantity demanded ($Q_s > Q_d$), exerting downward pressure on the price.

Gross Domestic Product (GDP)

The total market value of all final goods and services produced within a country's borders during a specified time period.

Per Capita GDP

Total Gross Domestic Product divided by a nation's total population ($\frac{\text{GDP}}{\text{Population}}$), used as a measure of average economic output per person.

Nominal GDP

Gross Domestic Product evaluated using the current market prices existing during the time of measurement, without adjusting for price level changes.

Real GDP

Gross Domestic Product evaluated using constant base-year prices to remove the distorting effects of inflation and isolate actual physical output changes.

Business Cycle

The periodic, recurring fluctuations in macroeconomic activity over time, composed of expansions, peaks, contractions, and troughs.

Recession

A significant and widespread decline in economic activity lasting more than a few months, typically marked by declining real GDP and rising unemployment.

Intermediate Goods

Goods that are utilized as inputs in the manufacturing or production of other final goods, which are excluded from GDP calculations to prevent double counting.

Final Goods

Goods and services purchased by their ultimate end user that are counted directly in GDP.

Gross National Product (GNP)

The total market value of all final goods and services produced by resources and factors owned by a nation's residents, regardless of where the physical production occurs.

Net Exports ($NX$)

Work-Eligible Population

The civilian noninstitutional population aged $16$ and older who qualify under standard statistical criteria to participate in the labor force.

Labor Force

The total pool of individuals within the economy who are either currently employed or actively seeking work ($\text{Labor Force} = \text{Employed} + \text{Unemployed}$).

Unemployment Rate ($u$)

The percentage of the labor force that is unemployed, calculated using the formula $u = \frac{\text{Number Unemployed}}{\text{Labor Force}} \times 100$.

Creative Destruction

The economic process whereby emerging technologies, new products, and innovative industries displace and render obsolete older established firms and occupations.

Structural Unemployment

Unemployment resulting from persistent mismatches between the skills or geographic locations of job seekers and the evolving structural needs of employers.

Frictional Unemployment

Short-term, temporary unemployment that arises as individuals transition between jobs or enter the labor market while seeking an optimal match.

Cyclical Unemployment

Unemployment attributable to macroeconomic downturns, recessions, and deviations from potential GDP within the business cycle.

Natural Rate of Unemployment ($u^*$)

The normal, sustainable long-run rate of unemployment occurring when cyclical unemployment equals zero ($u^* = \text{Frictional} + \text{Structural}$).

Full-Employment Output ($Y^*$)

The potential level of real output an economy can sustainably produce when resources are utilized normally and unemployment is at its natural rate.

Discouraged Workers

Nominal Wage

The current face-value dollar wage paid to a worker, unadjusted for the prevailing price level or inflation.

Real Wage

The inflation-adjusted wage representing the actual volume of goods and services a worker's earnings can buy, calculated as $\frac{\text{Nominal Wage}}{\text{Price Index}} \times 100$.

Menu Costs

The tangible operational and administrative expenses incurred by businesses when re-evaluating and physically changing their posted prices.

Equation of Exchange
