Economics Resources, Opportunity Cost, and the PPF
Introduction • Today we will be talking about how scarcity requires individuals, businesses, and governments to make economic decisions that involve tradeoffs. • Rolling Stones • Cant always get what you want
Vocab for this lesson • Goods • Services • Factors of Production • Entrepreneurship • Capital • Productivity • Opportunity Cost • Production Possibilities Frontier
What do we remember? • Definition of economics • About resources? • Scarcity is everywhere • Goods—physical objects produced for sale • Services—Activities done for us by others • Scarce because of the resources needed • Land • Labor • Capital
Scarcity is forever, Shortages Temporary • Shortage—lack of something that is desired • Less of a good or service available than people want at the current price • Causes • Trends in fashion • Musical acts • Wars and natural disasters (Katrina)
How are goods produced? • Economists look at inputs and outputs • Inputs---Factors of production • Go into the process (land, labor, capital) • Outputs • Goods and services produced • Some look at entrepreneurship • Willingness to take risks involved in starting a business
Land Resources • More than just physical property • Really is “gifts of nature” • Air • Soil • Water • Solar energy • Electromagnetic Spectrum • Perpetual, Renewable, Non Renewable
Labor Resources • Labor • The time and effort people devote to producing goods and services in exchange for wages • Physical and mental • Human capital • Knowledge and skill that people gain • Impossible to overstate importance • Nigeria vs. Japan
Capital Resources • Tools, machines, and buildings used in the production of other goods and services • Money is financial capital • Pizza delivery car is capital good • Since Industrial Revolution capital has been replacing labor • Good or bad?
Put it all together… • Three resource types are scarce • Use them efficiently, increase productivity • Productivity = output/input (any individual input) • Example: Lumber mill productivity • Ratio of board feet produced per hour • How do you raise productivity?
Making choices • What do we give up when making a choice? • Economists assume people seek to make themselves better off • Maximize the utility of their decisions • Utility is satisfaction or pleasure one gains from consuming a product or service • Example: Which college to attend • Never easy---never have total information
Opportunity Cost • The best thing we give up to get what we want • Example: Mick Jagger • Musician, or… • College degree • Thinking at the margin • Seldom all or nothing • Law of diminishing marginal utility
How to measure what we gain and lose in choices? • The Production Possibilities Frontier • Economic model • Line graph • Shows how economy can use its resources to produce two goods • Helps identify tradeoffs and opportunity costs • Shows economic efficiency • Using resources to produce maximum
