Passengers can buy souvenirs or rent a car at the airport or in the city-center. This paper develops a basic model with unit demands for airport ancillary and city-center demands to derive equilibrium pricing strategies of profit-maximizing airports and city-center companies and evaluates them from the social viewpoint. Passengers are myopic in the sense that only ticket prices matter for flight decisions or foresighted in the sense that non-aeronautical airport and city-center supplies matter for flight decisions, too. We find that the welfare evaluation of equilibrium airport pricing behavior can be independent of whether passengers are myopic or foresighted.

旅客可以在机场或市中心购买纪念品或租车。本文建立了一个基本模型，该模型具有对机场辅助设施和城市中心需求的单位需求，以得出使机场和城市中心公司实现利润最大化的均衡定价策略，并从社会角度对其进行评估。旅客是近视的，从某种意义上说，机票价格只对航班决定很重要；从远见的角度来说，非航空机场和市中心的供应也对航班决定很重要。我们发现，均衡机场定价行为的福利评估可以独立于旅客是近视还是有远见的。
