Economic Terms from A to B

The ability of a country, individual, or company to produce a good or service more efficiently than competitors, using fewer resources to produce the same output. This concept, introduced by Adam Smith, forms the basis for understanding international trade patterns.

A tax based on the assessed value of an item, such as property or goods. Sales taxes and property taxes are common examples of ad valorem taxes, where the tax amount is calculated as a percentage of the value.

The total demand for all goods and services in an economy at a given price level and time period. Aggregate demand is calculated as the sum of consumption, investment, government spending, and net exports (GDP components).

The total supply of goods and services that firms in a national economy plan on selling during a specific time period. Aggregate supply is the total amount of goods and services that firms are willing to sell at a given price level.

The process of spreading out a loan into a series of fixed payments over time. Each payment covers both the principal and interest, with the loan balance decreasing with each payment until it is fully paid off.

The practice of taking advantage of price differences between markets. Arbitrageurs buy assets in one market where the price is low and simultaneously sell in another market where the price is high, profiting from the price difference.

A resource with economic value that an individual, corporation, or country owns or controls with the expectation that it will provide future benefit. Assets include cash, investments, property, equipment, and intellectual property.

A situation in which a country is self-sufficient and does not trade with other countries. In economic theory, autarky is the opposite of free trade and is rarely practiced by modern economies.

The total cost of production divided by the total quantity produced. Average cost includes both fixed costs and variable costs and helps firms determine the most efficient level of production.

Total costs (fixed and variable) divided by total output. Average total cost typically decreases at first as production increases due to spreading fixed costs over more units, but eventually increases due to diminishing returns.

A record of all economic transactions between the residents of a country and the rest of the world in a particular period. It includes the current account, capital account, and financial account.

The difference between a country's exports and imports of goods. A positive balance (exports exceeding imports) is called a trade surplus, while a negative balance (imports exceeding exports) is called a trade deficit.

Any obstacle that makes it difficult for a new competitor to enter a market. Barriers can include government regulations, high startup costs, brand loyalty, patents, or control of essential resources.

A market condition in which securities prices fall 20% or more from recent highs due to widespread pessimism. Bear markets are typically associated with economic recessions and declining investor confidence.

A standard against which the performance of a security, investment strategy, or investment manager can be measured. Common benchmarks include stock market indices like the S&P 500 or the Dow Jones Industrial Average.

A measure of a security's volatility in relation to the overall market. A beta greater than 1 indicates higher volatility than the market, while a beta less than 1 indicates lower volatility. Beta is used to assess systematic risk.

An illegal market where transactions occur without government knowledge or approval. Black markets typically arise when government restrictions, price controls, or rationing create excess demand that cannot be satisfied legally.

A debt investment in which an investor loans money to an entity (corporate or governmental) that borrows the funds for a defined period at a fixed interest rate. Bonds are used by entities to raise capital for various purposes.

A period of rapid economic expansion characterized by rising GDP, decreasing unemployment, increasing consumer confidence, and often rising asset prices. Booms are part of the business cycle and are typically followed by a contraction or bust.

The tendency of consumers to continue buying the same brand of goods rather than competing brands. Companies work to build brand loyalty through quality products, positive customer experiences, and effective marketing.

The point at which total revenue equals total costs, resulting in neither profit nor loss. Knowing the breakeven point helps businesses determine the level of production or sales needed to cover all costs.

A financial situation that occurs when spending exceeds revenues. In the context of government, a budget deficit happens when government spending exceeds tax revenue, requiring borrowing to cover the difference.

A market condition in which securities prices are rising or are expected to rise. Bull markets are generally characterized by optimism, investor confidence, and expectations that strong results will continue.

The fluctuation in economic activity that an economy experiences over a period of time. A business cycle consists of expansions (economic growth) and contractions (recessions), which occur in repeating patterns.

In economics, this concept refers to how small changes in economic variables can have large, unpredictable effects on the economy as a whole. The term is borrowed from chaos theory, where it suggests that small initial differences may lead to vast unforeseen consequences.
