GREGHEC GREGHEC
The ”Groupement de Recherche et d’Etudes en Gestion à HEC Paris (GREGHEC)” is a CNRS - HEC Paris joint research lab. It is located on the HEC campus in Jouy-en-Josas.
GREGHEC is one of the largest joint research laboratories in the fields of economics and management in France.
About the GREGHEC
GREGHEC brings together all the research conducted at HEC Paris and, as such, comprises both disciplinary and cross-disciplinary work. The research activities are organized both across the eight academic departments of HEC Paris corresponding to the main management disciplines and across several multidisciplinary research centers.
GREGHEC is composed of a unique team of 180 researchers (CNRS researchers, HEC faculty and PhD students). It has been a Joint Research Laboratory (or « UMR » for « Unité Mixte de Recherche ») CNRS - HEC Paris since 2006.
Christophe Pérignon, Associate Dean for Research of HEC Paris has been the head of GREGHEC since July 2016. He relies on a Laboratory Council made up of 10 persons elected or nominated (6 researchers, one PhD student, the administrative manager of the Lab and the Dean of Faculty of HEC Paris).
The Laboratory falls within the Section 37 « Economics and Management » of the CNRS National Committee for Scientific Research (CoNRS) and within the CNRS Human and Social Sciences Institute (InSHS). The members of the GREGHEC with permanent positions are called to elect their representatives in the GREGHEC Laboratory Council and in the section 37, but also representatives in two scientific boards of the CNRS (the CNRS Scientific Board and the Scientific Board of the InSHS).

Title:
“When AI Assists at the Frontline: External and Internal Marketing Effects in the Context of Banking Mortgages.”
Abstract:
While Artificial intelligence (AI) increasingly assists frontline employees (FLEs) in their tasks, its implications remain uncertain. Against this background, this research focuses on examining the effects of AI assistance on both external (customer satisfaction, market performance) and internal (employee satisfaction) marketing outcomes. Findings from quasi-experimental evidence in a banking context, reveal that AI-assisted FLEs adopt more conservative behaviors, resulting in a 5% decrease in mortgage approvals and a 7% reduction in default payments, but at the cost of a 10% decline in customer satisfaction. A follow-up textual analysis and survey provide insights into the underlying process, suggesting that AI-generated solutions tend to be rigid and less open to alternative possibilities, which in turn reduces FLEs’ satisfaction. Controlled experiments test and further qualify this process evidence, showing that AI’s standardized outputs limit employees’ perceived job autonomy and satisfaction, regardless of their awareness of AI involvement. This research advances the AI marketing literature by showing that AI’s role at the frontline is not inherently supportive but must be carefully aligned with the characteristics of frontline nonroutine tasks. Its insights can help marketers harness the potential of AI-assisted frontline work while mitigating unintended downstream effects on employees and customers alike.
