Beginning to Think Like an Economist …is this a good thing?
Defining Economic Goods • Utility • Satisfaction you receive from consuming a product • Good vs. Bad • Tangibility • Can the good be touched or is it a service?
Defining Economic Goods • Resources or factors of production used • Land: natural resources • Labor: Physical and mental talents of people • Capital: produced goods that can be used as inputs for further production • Entrepreneurship: talent of organizing resources, seeking new opportunities, and developing new ways of doing things
Remember Scarcity Runs the Show… • What was scarcity?? • So…how do we make sure that only those who REALLY need the good get it?? • Prices • System of rationing of the good • Cause people to compete for the item
Opportunity Cost • Value of the next best alternative foregone • Pizza vs CD • Pizza for $1.00 per slice; CD for $15.00 • Revolutionary War • The British and their red coats
Opportunity Cost • Big Macs • Big Macs in Japan cost $8.25 • Highway System • Paid for with taxes
Summary Statement of Scarcity and Related Concepts
Costs and Benefits at the Margin • What is the margin?? • The “last” or “additional” • Marginal Cost • The cost of the “last” unit employed • Marginal Benefits • The benefit of the “last” unit employed • Unintended effects • Minimum wage • Gun bounties • Seat belts
Efficiency • What is the “right amount” of time to study? • Right amount = optimal or efficient amount • Marginal Costs = Marginal Benefits
Economic way of thinking includes… • Analyzing scarcity • Look at opportunity cost of decisions • Measure costs and benefits • Look at marginal effects • Examine unintended effects
Economic Thinking Errors • Association vs. Causation • You hit red lights because you are running late • Don’t study for a test so you fail • Fallacy of Composition • What is good for the individual is good for the group • Forgetting Ceteris Paribus • All else remains constant
Model • Simplified version of reality • Includes only the “important” aspects • Why is a model necessary??
Parts of a Theory • Variables • Magnitudes that can change • Assumptions • Ideas about event that will not allow to change • Hypothesis • Educated guess • Predictions • Based on hypothesis and assumptions
Scientific Approach • What do you want to predict/explain? • What variables are important? • State assumptions • State hypothesis • Test • If results are good…Yeah You!! • If results are bad…amend or reject theory
How do we judge theories? • Look at how well they predict • NOT by the assumptions • Example: Firms try to maximize profits • Do they think about this every second? • Probably not • Over the course of the year…make decisions to maximize profits
