Uncovering Optimal Gains In Hotel Mergers In The Presence Of Correlated Inputs: An Integrated Owa-Inverse Dea Framework, Amar Oukil, Ahmed-Amin Soltani Sep 2025

Uncovering Optimal Gains In Hotel Mergers In The Presence Of Correlated Inputs: An Integrated Owa-Inverse Dea Framework, Amar Oukil, Ahmed-Amin Soltani

The Journal of Engineering Research

Though Mergers and Acquisitions (M&A) are strategic transactions that have long been intertwined with the hospitality sector, the application of data envelopment analysis (DEA) to hotel M&A has been largely overlooked. In this paper, we introduce a new methodological framework that integrates inverse DEA (IDEA) and the ordered weighted averaging (OWA) operator to evaluate pairwise consolidations among hotels in the event of strong input correlation. While IDEA enables effective identification of all productive post-merger hotels, i.e., hotel mergers with potential input gains, the OWA aggregation is essentially prompted by the possible occurrence of inputs’ correlation. Rather than discarding inputs arbitrarily, …
