【正文】 eves all possible gainstotrade must be Pareto efficient. Pareto Efficiency ?Competitive equilibrium: –all close apartment renters value them at the market price pe or more –all others value close apartments at less than pe –so no mutually beneficial trades remain –so the oute is Pareto efficient. Pareto Efficiency ?Discriminatory Monopoly: –assignment of apartments is the same as with the perfectly petitive market –so the discriminatory monopoly oute is also Pareto efficient. Pareto Efficiency ?Monopoly: –not all apartments are occupied –so a distant apartment renter could be assigned a close apartment and have higher welfare without lowering anybody else’s welfare. –so the monopoly oute is Pareto inefficient. Pareto Efficiency ?Rent Control: –some close apartments are assigned to renters valuing them at below the petitive price pe –some renters valuing a close apartment above pe don’t get close apartments –Pareto inefficient oute. Further Extensions of the Model ?Over time, will –the supply of close apartments increase? –rent control decrease the supply of apartments? –a monopolist supply more apartments than a petitive rental market? A Quick Summary ?Economic modeling serves a specific purpose。 ?For the purpose, an economic model needs to make simplifying assumptions。 ?Economists do have value judgments, which are based on specified criterion.
