出租车行业规制与放松规制分析

对出租车行业的规制现状进行分析,依据经济学理论,利用博弈论以及社会福利理论分析出租车行业无规制条件下和规制条件下的社会福利情况。通过库诺特竞争模型,说明出租车行业在规制条件下的社会福利与无规制条件相比得到改善和提高;通过斯坦克尔伯格竞争模型,得出出租车行业在放松规制条件下的社会福利与规制条件下相比得到改善和提高。从社会福利角度对出租车的行业规制和放松规制进行分析,指出出租车行业规制的合理发展方向,为今后出租车行业的健康发展提供理论依据。

The passenger vessel services act and America's cruise tourism industry

The Passenger Vessel Services Act (PVSA) of 1886, a cabotage law, attempts to shield U.S. maritime shipping from foreign competition. It also applies to the U.S. cruise ship industry. The PVSA requires foreign cruise ships that carry passengers between U.S. ports to also stop at foreign ports. Norwegian Cruise Line America (NCLA), which operates one U.S. flagged cruise ship in Hawaii, wants the U.S. Customs and Border Protection to require foreign cruise ships offering Hawaii itineraries from the U.S. west coast to spend more time in foreign ports. We analyze the merits of NCLA's proposal. We argue that rather than making the PVSA even more protectionist, the law should be repealed.

Liner ship route schedule design with port time windows

This paper examines a practical tactical liner ship route schedule design problem, which is the determination of the arrival and departure time at each port of call on the ship route. When designing the schedule, the availability of each port in a week, i.e., port time window, is incorporated. As a result, the designed schedule can be applied in practice without or with only minimum revisions. This problem is formulated as a mixed-integer nonlinear nonconvex optimization model. In view of the problem structure, an efficient holistic solution approach is proposed to obtain global optimal solution. The proposed solution method is applied to a trans-Atlantic ship route. The results demonstrate that the port time windows, port handling efficiency, bunker price and unit inventory cost all affect the total cost of a ship route, the optimal number of ships to deploy, and the optimal schedule.
