Document Summary

The law of price states that a good must sell at the same price in all locations. This has the assumption of the inevitable elimination of all arbitrage. Arbitrage-the taking advantage of different prices in different markets for the same good. To make the law of supply, and this example, work, transaction costs must be zero. Giving different prices to different consumers not due to different costs. Need to be able to identify consumers" different willingness to play. Arbitrage of the product is not possible. (you cannot sell it, cannot sell an experience) Example: movie tickets- can"t sell the experience and that"s why they control the price. (it"s not netflix) People with higher demand (willingness to pay more) Those with lower price elasticity of demand (quantity demanded won"t change as much with price changes) Firm changes the price for every single unit sold, making all the economic surplus producer surplus, leaving no consumer surplus.
