You paid $35 for a ticket (which is non-refundable) to see SPAM, a local rock band, in concert on Saturday. Assume that $35 is the most you would have been willing to pay for a ticket. Your boss called, and she is looking for someone to cover a shift on Saturday at the same time as the concert. You would have to work 4 hours and she would pay you $11/hr. The psychic cost to you of working is $2/hr. Your economic surplus from going to work instead of seeing SPAM on Saturday is:
$1

You paid $35 for a ticket (which is non-refundable) to see SPAM, a local rock band, in concert on Saturday. Assume that $35 is the most you would have been willing to pay for a ticket. Your boss called, and she is looking for someone to cover a shift on Saturday at the same time as the concert. You would have to work 4 hours and she would pay you $11/hr. The psychic cost to you of working is $2/hr. Should you go to the concert instead of working Saturday?
No, the benefit of going to the concert is less than the cost.
The downward slope of the production possibilities curve illustrates the
Scarcity Principle
You want to buy a TV that regularly costs $250. You can either buy the TV from a nearby store or from a store that's downtown. Relative to going to the nearby store, driving downtown involves additional time and gas. The downtown store, however, has a 10 percent off sale this week. Last week you drove downtown to save $20 on some concert tickets, a 15 percent savings. Should you drive downtown to buy the TV?
Yes, because you will save more than $20

inconsistent reasoning; saving $20 is saving $20.
