Economics Fundamentals: Introduction, Price Controls, Production Factors, and Cost Theory

A comprehensive vocabulary review of core economic principles, encompassing introductory concepts, price controls, budget constraints, factors of production, and the theory of cost.

Economics

The study of how people use limited resources to satisfy their unlimited wants and needs.

Microeconomics

The branch of economics that studies the behavior of individuals, households, and businesses.

Macroeconomics

The branch of economics that studies the economy as a whole, including inflation, unemployment, and national income.

Utility

The satisfaction or usefulness a person gets from consuming a product or service.

Form Utility

Utility created by changing raw materials into finished products (e.g., turning wood into a chair).

Place Utility

Utility created by making products available where customers need them (e.g., selling food in a grocery store).

Time Utility

Utility created by making products available when customers need them (e.g., selling umbrellas during the rainy season).

Possession Utility

Utility created when ownership of a product is transferred to a customer (e.g., buying a cellphone from a store).

What to Produce?

The basic economic question addressing what goods and services should be produced (e.g., whether a company should produce food or clothing).

How to Produce?

The basic economic question addressing what methods and resources should be used in production (e.g., whether a company should use machines or workers).

For Whom to Produce?

The basic economic question addressing who will receive or consume the products (e.g., whether products should be made for low-income or high-income consumers).

Scarcity

The condition that happens when resources are limited but human wants are unlimited.

Opportunity Cost

The value of the next best alternative that you give up when making a choice.

Price Control

A government intervention that happens when limits are set on the prices of goods and services.

Price Ceiling

The maximum price that sellers are allowed to charge, usually imposed by the government to protect consumers from very high prices.

Price Floor

The minimum price that sellers are allowed to charge, usually imposed by the government to protect producers or workers (e.g., minimum wage).

Budget Constraint

The spending limit of what a person can buy based on their available income and the prices of goods, represented by the formula $P_x Q_x + P_y Q_y = \text{Income}$.

Factors of Production

The resources used to create goods and services, consisting of land, labor, capital, and entrepreneurship.

Land

Natural resources used in production, such as water, soil, forests, and minerals; its economic reward is rent.

Labor

Human effort, skills, and work used in production, such as teachers, factory workers, and farmers; its economic reward is wages or salaries.

Capital

Man-made tools, buildings, computers, and equipment used to produce goods and services; its economic reward is interest.

Entrepreneurship

The ability to organize and manage a business while taking risks; its economic reward is profit.

Capital Intensive

A business or production process that uses more machines, equipment, and technology than human workers and requires large investments in equipment.

Labor Intensive

A business or production process that uses more human workers than machines and requires more manpower.

Cost

The amount of money or resources spent to buy something or produce a product.

Cost of Production

The total expenses a business pays to produce goods or provide services, including raw materials, workers' salaries, electricity, rent, and equipment expenses.

Theory of Cost

The economic theory explaining how the costs of producing goods and services change when the level of production changes, helping businesses understand expenses and make production decisions.

Fixed Cost (FC)

Costs that do not change even if production increases or decreases (e.g., monthly rent and insurance).

Variable Cost (VC)

Costs that change depending on the quantity produced or output (e.g., raw materials and packaging).

Total Cost (TC)

The total amount of fixed and variable costs, calculated by the formula $\text{TC} = \text{FC} + \text{VC}$.

Average Cost (AC)

The cost of producing one unit of a product, calculated using the formula $\text{AC} = \frac{\text{TC}}{\text{Quantity Produced}}$.

Marginal Cost (MC)

The additional cost of producing one more unit of a product, calculated by the formula $\text{MC} = \frac{\text{Change in Total Cost}}{\text{Change in Quantity}}$.
