6. RATIONAL DECISION MAKING

7. Rational Decision Making
Analyzing costs and benefits before making a decision
MARGINAL thinking is key
What is the cost/benefit of my NEXT decision
Past decisions don’t matter
this affects PRODUCERS AND CONSUMERS
A rational decision is made when the marginal benefit is equal to or greater than the marginal cost

8. Costs and Benefits For producers, this is simply measured in dollars
Marginal costs of the inputs vs. marginal revenue
For consumers, it is trickier
We measure benefits in terms of UTILITY
How “useful” is the item or service
We use “utils” as the measure for this

10. Another example
A person opens a business making sandwiches. He’s purchased a store and all of the food products, now he wants to hire some people. He decides to hire two people to start with and pay them $50 a day. His costs/benefits sheet for a month looks like this:

11. Rent/Food/Entrepreneurship = $750
1 Month
Rent/Food/Entrepreneurship = $750
Worker #
Cost
Production
Price/Sand 1
$750
250 sandwiches 5 2
Total Costs: =2250
Total Output: 500 x 5 = 2500

12. Should he hire worker #3? Why?
1 Month
Rent, Food, Entrepreneurship - $750
Worker #
Cost
Production
Price/Sand 1
$750
250 5 2 3
200 4
100
Should he hire worker #3? Why?
