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.

Finance professor and executive director of the HEC Energy and Finance Chair, Jean-Michel Gauthier, spoke to us on March 3, one week after Russia invaded Ukraine. Jean-Michel is a veteran of the energy business. As a partner at Deloitte, he moved to the energy consulting industry for 16 years, before joining HEC Paris’ finance department in 2006. The dramatic events developing in Ukraine lead us to discuss with Jean-Michel a key factor behind the conflict: the question of energy. Not just the pipelines that bring Europe 40% of its natural gas and much of its oil – but also the knock-on effects on all energy sources that prop up our global economy. He helps us understand what role energy is playing in this ongoing conflict and where these upheavals could lead the entire planet.

Activist short sellers are controversial hedge funders that some are calling the modern day Robin Hoods of the business world, others are denouncing as unethical profiteers. Most economists, however, recognize their short selling as a vital part of an efficient and liquid market. HEC academics Hervé Stolowy and Luc Paugam, with their coauthor Yves Gendron, from Université Laval in Quebec, spent three years researching the reports short sellers write on companies they suspect of nefarious activities. They link these narratives to the linguistic tools “ethos”, “pathos” and “logos”, first dreamt up by Aristotle in 350 B.C.E.. In the podcast, Hervé and Luc also share their unique exchanges with three of these sellers, people who rarely reveal their operations.

The upswing in inflation figures on both sides of the Atlantic, called “reflation”, continues to worry governments and the general public. But what is behind these inflationary pressures? What are the consequences of this 13-year-high in the euro zone (4.1% in October); and 30-year record surge in prices in the United States? To find out what caused these increases and to analyze what could happen in the future, we’ve turn to two HEC academics whose research is linked to the inflation question. Associate Professor Eric Mengus specializes in monetary and macro-economics. His colleague, Associate Professor Gaetano Gaballo is a researcher in the same domains, and he’s also worked for seven years as a senior economist at the Banque de France. In mid-October, they reflected on a wide range of issues linked to reflation.

HEC Professor of Strategy (Education Track) Olivier Sibony joins forces with Nobel-laureate Daniel Kahneman and legal scholar Cass Sunstein to publish Noise, a monumental study on a little-known – yet pervasive - flaw in human error. The trio thus reinvent a term for a variability of judgment pervading decision-making at all levels and in all fields. In an exclusive interview, Olivier shares insights into a groundbreaking work that has shot into bestseller lists worldwide. It comes a day after the publication of the book’s French edition. And weeks before the arrival of Nobel laureate Daniel Kahneman’s visit to HEC on October 7, to accept the title of “Honoris Causa Doctor”. The interview was recorded on May 6, 2021.
