cost benefit analysis

=> benefits>costs

- qualifying costs and benefits (how to compare stocks at different times, currencies or risks)

- steps

find costs by looking at market price and quantity
find benefit

net value of the project: benefits-costs

--> positive: competitive markets (condition when goods are bought and sold at the same price, price determines value of the good-personal opinion on "fair price" is irrelevant)

why ppl buy and sell stocks? (not a competitive market, ppl have different views on the market value of certain stocks)
