Attention is focussed on a type of strategic alliance of the container shipping industry: vessel sharing agreements. In such consortia carriers jointly provide—but independently sell—a liner service. The strategic alliances studied in this work have not been extensively analyzed in the theoretical literature; a new model is proposed that embodies their main distinguishing features. By it, an examination is provided of the effects on equilibrium prices, equilibrium aggregate quantities and consumer welfare of the formation and enlargement of vessel sharing agreements. A positive answer is developed to the question raised in the title of the present work that supports a laissez-faire policy for these consortia.

注意力集中在集装箱航运业的一种战略联盟上：船只共享协议。在此类财团中，承运人联合提供（但独立出售）班轮服务。在理论研究中，尚未对本文研究的战略联盟进行广泛的分析。提出了一个体现其主要区别特征的新模型。通过它，研究了船舶共享协议的形成和扩大对均衡价格，均衡总量和消费者福利的影响。对于本工作的标题提出的问题，人们提出了肯定的答案，该问题支持对这些财团采取放任政策。
