Economic Reasoning An Economic Way of Thinking
  • Reference Chapter 1.1-2

5
Scarcity

next available page Economic Reasoning
Basic Economic Principles
  • Scarcity Wants Resources

Scarcity is the condition where our wants are
greater than our resources
None of us can have as much as we want of
everything we want --Oliver Wendall Holmes
What are wants????
7
Economists claim that wants are unlimited. Do you
agree? Why/why not?
  • tangible
  • intangible

8
Philosophers have confronted the unlimited nature
of human wants
9
Wants
  • anything that gives us utility or satisfaction
  • something that provides utility is a good
  • disutilitybad

10
Scarcity Wants Resources
  • What are resources?

11
Resources
  • whats needed to produce a good or service

12
Scarcity Choices
  • Because there is scarcity, choices have to be
    made.
  • personal
  • communally
  • nationally
  • globally
  • Choices are made be examining the costs and
    benefits of each option
  • a person will generally or always choose the
    option where benefits costs

13
Choice Opportunity Cost
  • When a choice is made, an opportunity cost is
    incurred.
  • Opportunity Cost
  • the most valued alternative
  • what you would have done
  • your next most valuable alternative
  • what you gave up to do what you did
  • not what you could have done
  • not price

14
You can incur an opportunity cost without
spending any money.
  • Give an example.

15
Lets Make a Deal!!!
16
Choices have to be made!
  • Door 1--Phantom?
  • OR
  • Door 2 A house inVista 300,000
  • Honda Accord MSRP of 25,000
  • Gas allowance of 3,000
  • Monthly allowance for shopping of 1,000 for 1
    year
  • OR
  • Door 3--A 340,000 trip around the world

17
  • When you forgo doing homework to get on Facebook,
    your opportunity cost for getting on Facebook was
    your homework.
  • Your choice. Your opportunity cost

18
Is the opportunity cost for attending high school
the same for all students?
19
Changes in opportunity costs change behavior
  • Increase opportunity cost do less of it
  • Decrease opportunity cost do more of it

20
Increase the Opportunity Cost-Do Less of It
Im hungry. What should I do?
  • Decision
  • Eat at Jack-In-The-Box
  • Youll do less of this.
  • Opportunity Cost
  • Eat at Mc Donalds
  • High Opportunity Cost
  • MacDonalds reduces prices
  • More choices added at Mickey Ds
  • Certified Cleanest Fast Food Restaurant in SD
    County

21
Decrease opportunity cost Do More of it
  • Decision
  • Eat at Jack-In-The-Box
  • Youll do more of this.
  • Opportunity Cost
  • Eat at McDonalds
  • Low Opportunity Cost
  • McDonalds raises prices
  • Only serves strawberry shakes
  • E. Coli outbreak

22
The Global Economy Employment
  • Benefit wages
  • per unit of time
  • Opportunity Cost Time
  • Leisure Forfeited
  • Opp.Cost of a Big Mac (1994)

23
Scarcity Rationing Device
  • Because there is scarcity there must be a
    rationing device
  • a means of deciding who get what and how much of
    available resources or goods.

Rationing device

Scarcity Competition
  • Because there is scarcity, we can infer there
    will be competition

28
More Ways to Think Like an Economist
  • trade-offs
  • decisions made on the margin
  • unintended consequences

29
Another consequence of scarcity Trade-offs
  • More of one thing frequently means less of
    something else.
  • Trade-0ff when more of one thing necessarily
    means less of something else.

30
Choices made on the marginMarginal choices made
by comparing marginal costs to marginal benefits
  • What will be the costs/benefits of
    doing/making/buying a bit more?
  • What would be the marginal cost or benefit of
    studying 1 more hour?
  • buying another hamburger?
  • spending another hour at the beach?

marginal additional

  • Has anything ever turned out differently than you
    intended?
