Gender diversity in corporate boards of directors has long been on the agenda, but whether and when investors reward companies that make efforts towards such inclusion remains an open question. Researchers in Accounting Crystal Shi (HEC Paris), April Klein and Mary Brooke Billings (New York University) investigate whether the #MeToo movement had an impact on investors' perceptions of the benefits of having a diverse and inclusive corporate culture, as reflected by the gender makeup of corporate boards.

Global credit rating agencies (CRAs) play an important role in economic growth or decline. Generous credit ratings may allow businesses to take on too much debt, at risk of defaulting. Overcautious ratings can hinder their access to finance, stifle investment, slow growth. A study by award-winning HEC Paris researcher Professor Pepa Kraft and collaborators in the U.S. and Hong Kong suggest that CRAs ratings are influenced by their country-level market share.

As Europe faces postwar records in forced migration from the east and south, ad hoc citizen groups have been sprouting up to ease the hardships of their new homelands. To illustrate this, HEC Assistant Professor David Crevlin publishes a detailed study on the rapid and effective response of German citizens to the unprecedented wave of migrants in 2015. A lesson of integration for all Europe?

The methods and aims of activist short sellers and financial analysts are often at odds. In a highly competitive environment, there is a battle for narrative authority, with short sellers often criticizing analysts. New research examines this struggle, and how — or if — analysts respond to challenges.

In the United Kingdom, more than 700 Post Office workers were wrongfully convicted of theft, fraud and false accounting between 2000 and 2014. That was the result of a fault in Horizon, a Fujitsu computer system used by the UK Post Office. How can AI solutions be developed to detect and prevent such intelligent anomalies? To answer these questions and more we have turned to HEC Professor of Accounting and Management Control, Aluna Wang. She is also chairholder at Hi! PARIS Center on Data Analytics and Artificial Intelligence.
This special issue aims to show the excellence and diversity of the research conducted by HEC Paris PhD candidates and alumni. You will find a selection of cutting-edge findings, answering crucial questions such as: Is AI a threat to human creativity? Should we listen to the Wall Street gurus? How to better manage one’s promotion? How much do we value our private data? What are ambiguity and risk attitudes? How bad is the mere presence of a phone? HEC Paris PhD Program, headed by finance professor Johan Hombert, supports its students throughout their thesis writing and job placement in the best universities and business schools, such as the MIT, Wharton and Harvard Business School. Most PhD alumni continue to collaborate with professors at HEC, thanks to the strong relationships they have developed during their journey.
The year 2015 marked a cesura in Europe’s recent history to “the largest migration movement of people that Europe has seen since 1945” (Financial Times, 2015). Private citizens quickly and efficiently organized to assist the settling of 20,000 of refugees crossing borders every day in Germany, compensating for the state’s initial inability to handle the situation (The Economist, 2015). Researchers have investigated the early organization that led to the quick response of those citizens to manage a crisis. In this interview, David Twardowski Crvelin, Assistant Professor of Accounting and Management Control at HEC Paris, discusses the conditions that help the inclusion of migrants in business and society.
Social entrepreneurship is characterized by a deep commitment to a social cause and the desire to develop new business models with economic, social, and ecological impacts. But can people be trained to become better at social entrepreneurship? HEC Paris Professors Thomas Åstebro and Florian Hoos found that social entrepreneurship training works, but only if carefully designed.

Are the efforts of transparency by the pharmaceutical industry sufficient to regain the trust of the world population? The COVID-19 pandemic has taken the world hostage since March 2020, yet there is hope that this health crisis may be vanquished this year, thanks to the approved vaccines by Pfizer/BioNtech and Moderna. While there are ongoing campaigns encouraging vaccination, there are nonetheless doubts about these newly-developed vaccines. This reticence compromises the effectiveness of vaccination drives already underway. HEC Paris Professor Vedran Capkun tells us why transparency is critical in this current context. He explains what the outcome of the production of these vaccines represents for the pharmaceutical industry.
New research analyzes how activist short sellers’ “research reports” convince investors that the companies they target are overvalued. Professors Luc Paugam and Hervé Stolowy of HEC Paris and Yves Gendron of the Université Laval found that the share price of companies targeted by major activist short sellers drop by 11.2%, on average, over three days. Target firms are also more likely to be subsequently delisted, suspended from stock exchanges, or to go bankrupt. Who are activist short sellers and how do they police financial markets?
