The purpose of this article is to analyse the relation of technical efficiency to stock market prices in the US airlines industry. Technical efficiency is an indicator, dedicated to productivity analysis, taking into account the industry structure. It enables the quantification of gains related to productive competitive advantage. Based on a sample of 28 carriers in the US airlines industry (1990-2010), we provide evidence of a statistical relation between technical efficiency and monthly stock prices. This relation is significant for the two months prior the official disclosure of the technical information. This result indicate that financial information is incrementally subsumed from technical reports. Lastly, based on nonparametric methodological framework, we propose competing modelizations of technical efficiency and we evaluate it in the light of their value relevance.
