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.

In 1984, a group of young boys living in poor neighborhoods in Montreal took part in a unique experiment. For two years, they received coaching in social skills like self-confidence and perseverance. A new assessment by HEC Professor of Economics Yann Algan, with Elizabeth Beasley, Sylvana Cote, Jungwee Park, Richard E. Tremblay and Frank Vitaro, now reveals the lifelong benefits of this work, not only in terms of life outcomes for the subjects themselves, but also for society at large.

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.

For the 32nd Olympic Games, one of South Africa’s modern icons, 800-meter champion Caster Semenya, will not be making the trip northwards. She has been barred from the Tokyo Olympics where she had hoped to defend a crown she won in 2012 and 2016. We discuss with Professor Matteo Winkler the legal, sociological and ethical implications of the Caster Mokgadi Semenya v. IAAF (now World Athletics) case. World Athletics’ regulations target female athletes like Semenya who are born with naturally high levels of testosterone, a characteristic that was labelled first as “hyperandrogenism” and then as “difference of sexual development”. Winkler and fellow academic, Doctor Giovanna Gilleri from the European University Institute published a 40-page study deconstructing the narratives surrounding the case and reflecting on the relationship between the law of sports, politics, gender and bodies – and the West’s sometimes uncomfortable position on femininity in the Global South.

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?

A major issue facing companies that use AI, algorithmic bias can perpetuate social inequalities — as well as pose legal and reputational risks to the companies in question. New research at HEC Paris offers a statistical method of tracking down and eliminating unfairness.

The COVID-19 pandemic has fostered the sharing of conflicting and unsubstantiated claims by public figures. Early November, a deeply divided nation elected Joe Biden as the President of the United States. A recent research published by professors Anne-Sophie Chaxel of HEC Paris and Sandra Laporte of Toulouse School of Management reveals that individuals believe in unsubstantiated claims when shared by favorite public figures, explaining polarization in opinions. In this article, Anne-Sophie Chaxel explains how rational people come to strongly believe in unchecked claims.

Global warming is one of the most pressing issues of the 21st century. In order to meet this unprecedented challenge, States and sub-state entities have decided to use an original regulatory instrument: a trading system wherein pollution rights can be exchanged (i.e. a ‘carbon market’). HEC Paris Professor Van Waeyenberge explains why the collaboration between countries has not yet led to satisfying results, and what can be done about it. Given the urgency of the situation, one cannot possibly reconceive or reimagine the current system from scratch, but one can improve it by encouraging complementary measures through the coordination of the various existing initiatives. This coordination could take place via the connections and interlinkages between the different carbon markets initiatives and through the use of new technologies such as the blockchain to implement it.
