Laws of Economics
• Everything is scarce.
Is there anything you consume that is not scarce?
What does it mean to “consume” something?
• Every choice includes an opportunity cost (tradeoff).
What do you give up in order to get something else?
Mom-Pop shops v. Big Box Retailers
Pollution v. No Pollution
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
Laws of Economics
You want it.
• Everything is scarce.
• Every choice includes an opportunity cost (tradeoff).
• The cosmos is a non-linear place.
• People respond to incentives.
What are you going to
do about it?
You can’t
have it.
Laws of Economics
Economics is often non-intuitive.
When it comes to economics, human intuition sometimes
fails because the human mind has evolved to wring
maximal use out of limited information.
 Good for making snap decisions.
 Bad for making thoughtful decisions.
Left half of room: Put your heads down.
Right half of room: Write what you read.
The average person in Albania earns an
annual income of $600 (in U.S. dollars).
Right half of room: Put your heads down.
Left half of room: Write what you read.
The average person in the United States
earns an annual income of $32,000.
The average person on planet Earth earns
what annual income (in U.S. dollars)?
Anchoring
When we see a piece of information, we evaluate subsequent
information in light of the first piece of information.
Information
News interview of a single mother working three jobs to support
her family.
Policy Question
Do we need welfare reform?
Problem

Right half of room: Put your heads down.
Left half of room: Read and answer.
Every year in the U.S., 17,000 children are treated in
emergency rooms for injuries sustained in school
buses accidents.
Most of these injuries could have been avoided had
the children been wearing seat belts.

But, we’re talking about saving children’s lives.
You can’t put a price on that!
If it saves just one life, no price is too much!
Bring it on!
Spending $2.75 million on bus seat belts will save 1 life.
Spending $2.75 million on malaria prevention will save
275,000 lives.
Cost of 1 life saved via seat belts is 275,000 lives lost via
malaria.
Everything is
scarce.
Every choice
includes a tradeoff.
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!
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.

Economic Models
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.
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).
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.
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
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

Firms to produce the same amount of Red Stuff
using the one-third the amount of Red Labor.
