- Price is a measure of value (from 1 to 4)
- All possible beneficial transactions take place, this society could not be better off
- State and nonmarket social relationships are irrleevant
- equity is not relevant
What is the Pareto Optimality?
No transaction remains that would benefit anyone without hurting someone else more
What does the Tragedy of the Commons explain?
It explains the critical assumption that all resources are individually owned.
What is asymmetric information?
When one party to a transaction has information not possessed by the other, that party has an advantage (ex. Martha Stewart)
What is Adverse Selection?
The Circumstances that arise in financial markets when borrowers with the worse credit are the ones most likely to seek loans

What is the marginal rate of transformation and substitution?
- The amount of good B that must be given up to produce good A
- The amount of good B that must be given to people so they willingly give up a unit of A
What are the effects of efficiency when scarce resporces appear to be free?
- less will be produced than could be produced with other resource allocations
- the wrong "mix" of goods and services will be produced
