Shipping Costs and the Controversy Over Open Registry
研究采用超越对数成本函数比较开放登记船与传统登记船的成本，揭示取消开放登记可能推高航运成本，对航运市场产生影响。
Concern with safety in particular has resulted in efforts to phase out open registry of ships. This study employs a transcendental logarithmic framework to highlight some of the cost implications of adopting such a policy in terms of the higher shipping costs which would result. It compares the cost functions of open registry ships with those of ships registered under traditional mnaritime nations in order to offer some insights into the possible impacts on shipping markets of withdrawing the opportunities for shippers to elect for open registration.
