Online reputation matters in the food industry. With every star earned on Tripadvisor, for example, a popular eatery can attract more customers, bolster revenue and expand its business. What’s more, new research by HEC Professor of finance François Derrien and co-authors Alexandre Garel (Audencia Business School), Arthur Romec (TBS Business School) and Jean-Philippe Weisskopf (EHL Hospitality Business School) have confirmed there is a causal link between a restaurant’s ratings and its ability to service additional debt, making it easier for lenders today to identify successful restaurants and drive their growth.

If companies anticipate that the government might impose caps on carbon emissions, they will likely invest in green technologies. This, in turn, drives down the cost of achieving reductions for all. That’s according to HEC Paris finance professors Augustin Landier and Bruno Biais. In “Emission Caps and Investment in Green Technologies,” the co-authors also show that if these firms don’t think carbon restrictions are coming, they won’t invest, and the government eventually will find it too costly to the economy to impose caps. In other words, companies’ expectations about future government action play a crucial role in reducing the carbon emissions driving rapid climate change. So, ask the researchers, how can a balance be found? 4 key findings: Anticipating future regulations spurs green technology investments, lowering emission reduction costs; Early investments in green technologies create a self-fulfilling prophecy, facilitating feasible emissions caps; Private and public actions synergize for desired outcomes through a complementary equilibrium; One large investor can have a significant influence.

For a long time, addressing sustainability problems has been regarded as a technological challenge. Today, supporting the transition to a more sustainable world has transcended this technological status and emerged as a quintessential management, economic, and behavioral challenge. Within this realm, research in social sciences and management assumes a pivotal role, offering insights across various crucial dimensions of the transition.
At HEC Paris, the integration of research, teaching, and action is a fundamental philosophy that we embody. In today's dynamic landscape, where environmental and social challenges are increasingly prominent, HEC serves as a beacon of innovation and responsibility. As Europe's leading business school, we acknowledge our responsibility to guide future leaders in navigating the complexities of a world in flux.
Despite environmental, social, and governance (ESG) funds gaining popularity, their impact on reducing negative externalities, such as greenhouse gas emissions, may be limited if not approached strategically. In our study, entitled “Responsible Finance: How to Optimize Impact,” forthcoming in the Review of Financial Studies, we show that investment capital could actually influence the behavior of more highly polluting companies to drive positive change for the planet.
