QuestionAnswer
Capital All means of production (mainly plant and equipment) created by people.
Capitalism An economic system in which most economic decisions are made by private owners and most of the means of production are privately owned.
Change in Demand A change in the quantity demanded of a good or service at at least one price that is caused by demand factors other than a change in the price of that good or service.
Change in Supply A change in the quantity supplied of a good or service at at least one price that is caused by supply factors other than a change in the price of that good or service.
Circular Flow Model Goods and services flow from business firms to households in exchange for consumer expenditures, while resources flow from households to business firms in exchange for resource payments.
Communism An economic system characterized by collective ownership of most resources and central planning.
Demand A schedule of quantities of a good or service that people will buy at different prices; represented by D.
Demand Curve A graphical representation of the demand schedule showing the inverse relationship between price and quantity demanded.

Economics The efficient allocation of the scarce means of production toward the satisfaction of human wants.
Economic Problem When we have limited resources available to fulfill society's relatively limitless wants.
Entrepreneurial Ability [E] Ability to recognize a business opportunity and successfully set up a business firm to take advantage of it.
Equilibrium Price The price at which quantity demanded [Qd] is equal to quantity supplied [Qs].
Factors of Production The resources of land, labor, capital, and entrepreneurial ability.
Land Natural resources used to produce goods and services.
Law of Increasing Costs As the output of one good expands, the opportunity cost of producing additional units of this good increases.
Mixed Economy An economy in which production and distribution is done partly by the private sector and partly by the government.

Production Possibilities Frontier (PPF) A curve representing a hypothetical model of a two-product economy operating at full employment.
Scarcity The inability of an economy to generate enough goods and services to satisfy all human wants.
Socialism An economic system in which the government owns most of the productive resources except labor; it usually involves the redistribution of income.
Equilibrium Price The price at which quantity demand [Qd] is equal to quantity supplied [Qs].
Inelastic Demand A demand relationship in which a given percentage change in price results in a smaller percentage change in quantity sold.
Inferior Goods Goods for which demands decrease when people's incomes rise.
Normal Good A good whose demand varies directly with income
Perfectly Elastic Demand Curve A perfectly horizontal demand curve; the firm can sell as much as it wishes at that price.
Perfectly Elastic Supply Curve A perfectly horizontal supply curve; the slightest decrease in price causes the quantity supplied to fall to zero.
Perfectly Inelastic Demand Curve A perfectly vertical demand curve; no matter what the price is, the quantity demanded remains the same.
Perfectly Inelastic Supply Curve A perfectly vertical supply curve; quantity supplied remains constant no matter what happens to price.
Price Ceiling Government-imposed maximum legal price.
Price Floor Government-imposed minimum price (used almost exclusively to keep agricultural commodity prices up).
Rent Control Government-set price ceiling on rent.
Substitute Goods Products or services that can be used in place of each other. When the price of one falls, the demand for the other falls, and conversely with an increase of price.
Accounting Profit Sales minus explicit cost. Implicit costs are not considered.
Barrier to Entry Anything that prevents the entry of new firms into an industry.
Break-Even Point The low point on the firm's average total cost curve. If the price is below this point, the firm will go out of business in the long run.
Cartel A group of firms behaving like a monopoly.
Collusion The practice of firms to negotiate price and/or market share decisions that limit competition in a market.
Diminishing Returns If units of a resource are added to a fixed proportion of other resources, marginal output will eventually decline.
Diseconomies of Scale An increase in average total cost as output rises.
Economic Profit Sales minus explicit costs and implicit costs.
Economies of Scale Reductions in average total cost as output rises.
Explicit Costs Dollar costs incurred by business firms, such as wages, rent, and interest.
Implicit Costs The firm's opportunity costs of using resources owned or provided by the owner.
Kinked Demand The demand curve for a noncollusive oligopolist, which is based on the assumption that rivals will follow a price decrease and will ignore a price increase.
Long Run When all costs become variable costs and firms can enter or leave the industry.
Marginal Physical Product (MPP) The additional output produced by one more unit of input.
Normal Profits The return to the business owners for the opportunity cost of their implicit inputs.
Price Discrimination Occurs when a seller charges two or more prices for the same good or service.
Price Leadership One firm, often the dominant firm in an oligopolistic industry, raises or lowers price, and the other firms quickly match the new price.
Short Run The length of time it takes all fixed costs to become variable costs.
Shut-Down Point The low point on the firm's average variable cost curve. If price is below the shut-down point, the firm will shut down in the short run.
Variable Costs These vary with output. When output rises, variable costs rise; when output declines, variable costs fall.
Anticipated Inflation The rate of inflation that we believe will occur; when it does, we are in a situation of fully anticipated inflation.
Cost-Push Inflation Rising costs of doing business push up prices.
Cyclical Unemployment When people are out of work because the economy is operating below the full-employment level. It rises sharply during recessions.

Aggregate Supply The nation's total output of goods and services.
Aggregate Supply Curve showing the level of real GDP produced at different price levels during a time period, ceteris paribus.
Automatic Stabilizers Programs such as unemployment insurance benefits and taxes that are already on the books to help alleviate recessions and hold down the rate of inflation.
Budget Deficit When federal tax receipts are less than federal government spending.
Budget Surplus When federal tax receipts are greater than federal government spending. Business Cycle*Increases and decreases in the level of business activity that occur at irregular intervals and last for varying lengths of time.
