Séminaire Finance IGR-IAE


Le prochain séminaire Finance aura lieu le jeudi 30 mars 2017 de 10h00 à 12h30 en salle du conseil à l'IGR-IAE.

Nous aurons le plaisir d'accueillir Bertrand TAVIN, professeur assistant en finance à l'EM Lyon, et Matthieu BELAROUCI, maître de conférences à l'Université de Lille.

Matthieu viendra présenter son papier « The Valuation Role of Technical Efficiency: Empirical Investigation of the US airlines ».

The purpose of this article is to investigate the value relevance of technical efficiency, based on the publicly available reports of the US Department of Transportation, within the Linear Information Model (LIM) of Ohlson (1995). Referring to data envelopment analysis (DEA) and stochastic frontier analysis (SFA) we evaluate technical efficiency, which quantifies the productive competitive advantage of the firm. We investigate the value relevance of technical efficiency in tandem with information about technical characteristics of the US carriers’ operations and the accounting variables of the LIM. We provide evidence of a statistical relation between current technical efficiency and stock prices and returns. While the variables of the LIM explain the most part of stock returns, technical efficiency exhibits the highest incremental value relevance. Furthermore, the implementation of an accounting based proxy does not reach the value relevance of technical efficiency. The originality of this article lies in the investigation of theinformation dynamic of technical efficiency. Results indicate that the greatest value relevance of technical efficiency is associated with its greatest persistency relative to accounting numbers. We conclude that technical efficiency is an appropriate complement to accounting information for analysts and professional investors to perform estimates about the future value of the firm, especially when accounting is deteriorated by sector wide shocks.
