Deux heures de cours d'économie à SKEMA (avec E. Combe)

Value of the Information & Strength of the Argument

The lecture provides substantial value by synthesizing decades of economic research on M&A, offering clear explanations of key concepts such as build-or-buy decisions, market power, and synergies. Combe’s argumentation is solid, grounded in empirical evidence and real-world examples. He effectively debunks the myth of 1+1=3 by citing studies showing that over half of M&A deals destroy value. The discussion of the Fnac-Darty case adds practical insight into how competition authorities assess mergers. The lecture is well-structured, building from basic concepts to more nuanced analyses, and is suitable for both students and professionals seeking a deeper understanding of M&A economics.

Scientific Rigor, Source Quality, Title Accuracy

The lecture demonstrates high scientific rigor, with references to academic papers and empirical studies, such as the 2022 synthesis on build-or-buy decisions and the Harvard Business Review data on M&A failure rates. Combe, as a former competition authority official, brings authoritative expertise. The title accurately reflects the content, and the lecture is well-organized. The sources cited are credible, though the lecture does not provide full citations for all studies mentioned. The inclusion of the Fnac-Darty case study adds practical relevance. Overall, the lecture is scientifically sound and appropriately titled.

The title accurately reflects the content: a two-hour economics lecture on mergers and acquisitions delivered at SKEMA Business School.
