1. Laws of Economics Everything is scarce. Is there anything you consume that is not scarce? What does it mean to “consume” something? Every choice involves an opportunity cost (tradeoff). What do you give up in order to get something else? Mom-Pop shops v. Big Box Retailers Global warming v. Global warming

3. Laws of Economics The cosmos is a non-linear place. Opposing consumption forces: consumption & variety Opposing production forces: specialization & congestion People respond to incentives. Airplanes and car seats Entrepreneurship and taxes Russians and dead light bulbs

4. Laws of Economics Cascade of tradeoffs due to choice and incentives… Regulation:Require cars to have airbags so as to save lives. The tradeoff of safety vs. time… Airbag make cars safer thereby allowing people to drive faster yet maintain same level of safety as before. Cost per life saved = $720,000 …presents a tradeoff of lives saved via airbags vs. lives saved via other means…

10. Laws of Economics Cascade of tradeoffs and mitigation due to incentives… Regulate safety: The tradeoff of safety vs. time presents a tradeoff of lives saved via airbags vs. lives saved via other means… Each 1 life saved via heart transplant costs 15,700 lives that could have been saved via malaria treatment. …which, in turn, presents a tradeoff of lives saved vs. impact on the environment, etc., etc.

11. Laws of Economics Given that everything is scarce, every choice will involve a tradeoff.  Who decides what tradeoffs are acceptable? Deciding by vote allows everyone an equal say.  Should everyone have equal say? Should we weight each vote based on how strongly the voter feels about the tradeoff?  How do we know how strongly the voter feels?  Voter has incentive to lie!

12. Laws of Economics Prices are much more than “how much something costs.” Prices signal how strongly the community feels about things. All other things equal… The more people want something, the higher the price. The greater the opportunity cost of bringing something to market, the higher the price.

13. Economic Models

16. Criticism: Ignoring factors that impact model results Is the driver cautious? Does the driver have good reaction time? Criticism: Issues that invalidate the model The car isn’t moving. The car has no mass.

17. Economic Models The point of the economic model is to strip away: Irrelevant information (e.g., the color of the car), Relevant but individual specific information (e.g., the reaction time of the driver), and Relevant but negligible information (e.g., the mass of the driver).

18. The Players and the Goals In this experiment, there are WORKERS and FIRMS. WORKERS sell labor to the FIRMS. FIRMS make stuff and sell stuff to the WORKERS.

19. The Players and the Goals Two types of worker Red workers (know how to make Red stuff) Blue workers (know how to make Blue stuff) Each worker’s goal: Maximize utility Three things make you happy: Red Stuff, Blue Stuff, and Leisure

20. The Players and the Goals Two types of firm Red firms make and sell Red stuff Blue firms make and sell Blue stuff Each firm’s goal: Maximize profit Profit = Ending $ – Starting $
