1. Absolute Advantage: exists if a producer can produce more of a good than all other producers. 2. Comparative Advantage: a producer has comparative advantage if he can produce a good at lower opportunity cost than all other producers. 3. Economic Growth: occurs when an economy’s production possibilities increase. 4. Economics: the study of how people, firms, and societies use their scarce productive resources to best satisfy their unlimited material wants. 5. Human capital: the amount of knowledge and skills that labor can apply to the work they do and the general level of health that the labor force enjoys. 6. Inferior goods: a good for which high income decreases DEMAND 7. Law of Demand: There is an inverse or indirect relationship between the price of a product and the quantity of that product that consumers are willing and able to buy. 8. Law of Supply: There is a direct or positive relationship between the price of a product and the quantity of the product supplied by the producer. 9. Marginal Analysis: making decisions based up weighing the marginal benefits and costs of that action. 10. Marginal Benefit (MB): the additional benefit received from the consumption of the next unit of a good or service. 11. Marginal Cost (MC): the additional cost incurred from the consumption of the next unit of a good or service. 12. Marginal: the next unit or increment of an action. 13. Normal goods: a good for which higher income increases DEMAND 14. Opportunity Cost: the value of the sacrifice made to pursue a course of action. 15. Production Possibilities: different quantities of goods that an economy can produce with a given amount of scarce resources. 16. Productive Efficiency: production of maximum output for a given level of technology and resources. All points on the PPF are productively efficient. 17. Productivity: the quantity of output that can be produced per worker in a given amount of time. 18. Resources: called factors of production, these are commonly grouped into the four categories of labor, physical capital, land or natural resources, and entrepreneurial ability. (SUPPLY) 19. Scarcity: the imbalance between limited productive resources and unlimited human wants. Because economic resources are scarce, the goods and services a society can produce are also scarce. 20. Specialization: when firms focus their resources on production of goods for which they have comparative advantage, they are said to be specializing. 21. Substitute goods: two goods are consumer substitutes if they provide essentially the same utility to the consumer. 22. Substitution effect: the change in QDemanded resulting from a change in the price of one good relative to the price of other goods. 23. Technology: a nation’s knowledge of how to produce goods in the best possible way. 24. Trade-offs: scarce resources imply that individuals, firms, and governments are constantly faced with difficult choices that involve benefits and costs. 25. Utility: The use or satisfaction that a good or service provides to a consumer.
