	===Auctions===		===Auctions===
			Objective - get as much money as possible.

			*Ascending Bids - Keep calling prices until no one pays more
			**Types
			***Rational: Only bid up to your value
			***Psychological: May get carried away or want to win (value of item + value of winning)
			***Rule Following: Pretty much rational
			**Outcome, highest bidder will end up getting it at second price
			*Second price auction - Sealed bid but highest bidder gets it at second highest cost
			**Types
			***Rational: Bid your value
			***Rule Following: Close to rational
			***Psychological: Close to rational / random
			**Outcome, people make mostly rational bids. Same outcome as ascending bid auction
			*Sealed Bids - Everyone writes down a price, the highest price gets it at cost
			**Types
			***Rational: ?
			**Outcome: Same outcome as ascending bid auction and second price

			But...context matters.

			Designing incentive structures to get the outcomes we want. These are "Moral Hazard" problems.

			*C: cost of "good" effort
			*P: Probability of desired outcome despite !"good" effort
			Incentive to put forth "good" effort: M > c/(1-p). As both C and P go up, M goes up as well.

			Payoff to j = -x<sub>j</sub> + Β Σ x<sub>i</sub>
