This study examines the competitive conditions of the Containerized Liner Shipping Industry (CLSI). The degree of competition prevailing in this industry will be assessed using the Panzar and Rosse H-statistic. The properties of this non-structural methodology (e.g. using firm level data, robustness in small samples, no need to specify a relevant market, etc.) make it an excellent framework for assessing the degree of competition in the CLSI. The empirical specifications are based on an unbalanced panel of data regarding a sample of 18 major liner operators covering the period 1999 to 2008. A significantly positive unscaled value of the H-statistic has been found. This means that the hypothesis can be rejected that the CLSI market structure corresponds to a neoclassical monopoly, a collusive oligopoly or a conjectural variations short-run oligopoly.
