Chp 2 page 17

Goods

Def: Physical objects that can be produced for sale or use.

Sentence: Food, clothing, and cars are all examples of goods that satisfy consumer needs.

Connections: Related to Services (the other type of economic product); goods are tangible while services are intangible.

Chp 2 page 17

Services

Def: Actions or activities that are performed for a fee (usually money).

Sentence: A haircut, a doctor's visit, and tutoring are all services because you pay for someone's action, not a physical object.

Connections: Paired with Goods as the two categories of economic products; the US economy is heavily service-based.

Chp 2 page 17

Factors of Production

Def: The four resources needed to produce goods and services: Capital, Land, Labor, and Entrepreneurship.

Sentence: A bakery uses all four factors of production: ovens (capital), a storefront location (land), bakers (labor), and the owner's vision (entrepreneurship).

Connections: Each factor earns a different income: capital → interest, land → rent, labor → wages, entrepreneurship → profit.

Chp 2 page 17

Capital (Physical Capital / Capital Goods)

Def: The tools, machines, equipment, and buildings used to produce goods and services — NOT money.

Sentence: A factory's assembly-line robots are capital because they help produce output.

Connections: One of the four Factors of Production; distinct from Financial Capital (money used to fund business); related to Inputs.

Chp 2 page 20

Land

Def: All natural resources used in production, including water, minerals, forests, and the land itself.

Sentence: The oil drilled from underground and the farmland used to grow wheat are both classified as the factor "land”.

Connections: One of the four Factors of Production; includes both Renewable Resources (timber, water) and Nonrenewable Resources (oil, coal).

Chp 2 page 22

Labor

Def: The physical and mental effort people contribute to producing goods and services.

Sentence: The workers on an assembly line and the engineer who designed the product both provide labor.

Connections: One of the four Factors of Production; its quality is improved by Human Capital (education and training); linked to Productivity.

Chp 2 page 17

Entrepreneurship

Def: The initiative to combine the other three factors of production, take risks, and create new goods or services.

Sentence: When someone launches a startup by hiring workers, renting office space, and buying equipment, they are starting entrepreneurship.

Connections: One of the four Factors of Production; the entrepreneur earns profit (or absorbs losses); drives innovation and economic growth.

Chp 2 page 17

Opportunity Cost

Def: The value of the next-best alternative you give up when you make a choice.

Sentence: If you spend Saturday studying instead of working a shift that pays $80, your opportunity cost of studying is that $80.

Connections: Central to the PPF — every point on the curve involves an opportunity cost of producing more of one good; ties to the principle "Every choice has a cost" from Chapter 1.

Chp 2 page 17

Productivity

Def: The amount of output produced per unit of input (e.g., per worker or per hour).

Sentence: If a factory produces 500 units per worker per day instead of 300, its productivity has increased.

Connections: Higher productivity shifts the PPF outward (economic growth); related to Human Capital — better trained workers are more productive.

Chp 2 page 17

Production Possibilities Frontier (PPF) / PPC

Def: A graph showing the maximum combinations of two goods or services an economy can produce using all its resources efficiently.

Sentence: A country on its PPF producing more missiles must give up some butter, demonstrating opportunity cost.

Connections: Points ON the curve = Economic Efficiency; points INSIDE = underutilization/inefficiency; points OUTSIDE = currently unattainable without growth; relates to Opportunity Cost and Inputs/Outputs.

Chp 2 page 29

Economic Efficiency

Def: Using resources in a way that maximizes the production of goods and services with the least waste.

Sentence: An economy operating on its PPF is achieving economic efficiency because no resources are sitting idle.

Connections: Directly related to the PPF — efficient production means you're on the curve, not inside it; opposite of a Shortage or resource underuse.

Chp 2 page 19

Shortage

Def: A situation where the quantity demanded of a good or service exceeds the quantity available at the current price.

Sentence: During a natural disaster, bottled water often experiences a shortage as demand goes beyond supply.

Connections: Related to scarcity (Chapter 1) but not the same — scarcity is permanent and universal, while a shortage can be temporary and market-specific.

Chp 2 page 20

Inputs

Def: The resources (land, labor, capital, entrepreneurship) that go into the production process.

Sentence: Flour, sugar, an oven, and a baker's time are all inputs in producing a cake.

Connections: Part of the Production Equation (Inputs → Outputs); the four Factors of Production are the categories of inputs.

Chp 2 page 20

Outputs

Def: The goods and services that result from the production process.

Sentence: The finished cake ready for sale is the output of the bakery's production process.

Connections: Part of the Production Equation; measured by Productivity (output per unit of input); shown on the axes of the PPF.

Chp 2 page 20

Production Equation

Def: The relationship showing that inputs are combined through a production process to create outputs (Inputs → Production → Outputs).

Sentence: The production equation for a car company is as follows: steel, robots, and workers (inputs) go through assembly (production) to create vehicles (outputs).

Connections: Ties together Inputs, Outputs, Factors of Production, and Productivity into one framework.

Chp 2 page 20

Renewable Resources

Def: Natural resources that can be replenished over time through natural processes (e.g., timber, solar energy, water).

Sentence: A lumber company that replants trees after harvesting is sustainably using a renewable resource.

Connections: A subcategory of Land (factor of production); contrast with Nonrenewable Resources; sustainability affects long-term PPF position.

Chp 2 page 21

Nonrenewable Resources

Def: Natural resources that exist in fixed quantities and cannot be replaced once used up (e.g., oil, coal, natural gas, minerals).

Sentence: Coal is a nonrenewable resource.

Connections: A subcategory of Land; depletion can shift the PPF inward over time; contrast with Renewable Resources.

Chp 2 page 22

Human Capital

Def: The knowledge, skills, training, and experience that workers bring to the production process.

Sentence: A full scholarship for an surgeon in his/her years of medical school and residency represent a large investment in human capital.

Connections: Improves the quality of Labor (factor of production); increases Productivity; distinct from Physical Capital (machines) and Financial Capital (money).

Chp 2 page 22

Financial Capital

Def: The money used to buy the tools, equipment, and resources needed for production.

Sentence: A bank loan that a restaurant owner uses to buy a new oven is financial capital.

Connections: Distinct from Physical Capital — financial capital is money, physical capital is the actual equipment; NOT one of the four Factors of Production by itself.

Chp 2 page 24

Total Utility

Def: The total amount of satisfaction or pleasure one gets from consuming a specific amount of a good or service.

Sentence: After eating three slices of pizza, your total utility is the combined satisfaction from all three slices.

Connections: Increases as you consume more (up to a point); built up from Marginal Utility of each additional unit; eventually impacted by Diminishing Marginal Utility.

Chp 2 page 26

Marginal Utility

Def: The additional satisfaction or pleasure gained from consuming one more unit of a good or service.

Sentence: The first slice of pizza gives you huge satisfaction, but the fourth slice adds only a little; that small addition is its marginal utility.

Connections: Each additional unit's marginal utility typically falls (Law of Diminishing Marginal Utility); when it drops below zero, you've hit Negative Utility; adds up to Total Utility.

Chp 2 page 27

Law of Diminishing Marginal Utility

Def: The principle that as you consume more units of a good or service, the additional satisfaction (marginal utility) from each extra unit tends to decrease.

Sentence: An example of diminishing marginal utility is when your first cup of coffee in the morning is amazing; by the fourth cup you barely enjoy it.

Connections: Explains why Marginal Utility falls with each unit; eventually leads to Negative Utility; foundational to demand theory and consumer behavior in economics.

Chp 2 page 26

Negative Utility

Def: The point at which consuming an additional unit of a good or service causes dissatisfaction or displeasure rather than pleasure.

Sentence: Eating a tenth slice of pizza that makes you feel sick is an example of negative utility.

Connections: Occurs when Marginal Utility drops below zero; the extreme end of the Law of Diminishing Marginal Utility; Total Utility actually decreases at this point.
