What is a “trade off”

?????

Trade-off: exchanging one good for another

• Think of a trade-off as “weighing the pros & cons” in decision making

• A way to organize a decision’s factors

Examples of Trade Offs…

• If you choose to buy an iPhone, you’re going to give up some of your income…

• If you’re taking this class, you’re not at home sleeping….

What are benefits to both? That “list” is how you make your decisions…. & recognize trade-offs

?Example:

The ‘Would You Rather’ Game!o0o0o0o0o0o

The Cost of Trade-OffsThe cost is what you give up in order to get or do

something else

VS

Example: Time is a scarce resource…there are only so many hours per day so you prioritize (study vs. COD)

Opportunity cost: the value of the next best alternative that had to be given up to do

the action that was chosen• You constantly make trade-offs on a daily basis• The decisions you make when it comes to time or $

$ spent should be given thought• BUT even when given thought you give up using

that time or $$ for other factors• What is the BIGGEST BUMMER on that list of

factors?

Opportunity cost

Example

Right Now…. I’m writing this lesson for tomorrow….• Sleeping 4• Watching Tropic Thunder 2• Working on my Etsy site 6• Making jewelry 8• Working on my sister’s wedding 9• Spending time with my bf 3• Exercising 10• Eating 1• Looking for shoes online 7• Reading the ‘Life of Pi’ 5

There are 10 other things I could be

doing.

I’ve rated these things from 1-10.

1 = I’d rather be doing the most

10 = I’d rather be doing the leastSo…

What’s my opportunity

cost in writing this lesson?

Your Turn!You’re sitting in school right now.

List 10 other things/ alternative that you could be doing instead.Rank them from 1-10…

1 = you’d rather be doing this the most2 = you’d rather be doing this the least

Finally, circle your #1 or… your opportunity cost!

FOOD FOR THOUGHT: *Always be aware of your priorities (ranking) in decision making &

DEFINITELY your opportunity cost*

Sunk Costs

sunk costs are retrospective (past) costs that have already been “spent” and

cannot be recovered

- Movies- Break Ups- Crappy Food Order- …

What are ALL of the steps involved with

each of these?

The Approach to Sunk Costs

You shouldn’t consider PAST decisions when making FUTURE choices, since you cannot alter

what is in the past
