Electronic word of mouth: what marketers need to know
When buying products, consumers often look at information written by other consumers on the internet. In order words, they turn to electronic word of mouth (eWOM). Marketers can take steps to generate, support, and amplify eWOM and so influence consumers’ decision-making process. A trio of researchers have laid out an eWOM roadmap to help marketers and academics understand its inner workings and enhance its effects.

Optimizing Feed-In Tariffs to boost renewable energy production
Feed-in tariffs (FITs) are crucial tools to increase the adoption of renewable energy technologies. But setting them at the right level (price) is a balancing act. If they are poorly designed, they can backfire, stunting the industry and wasting public money. A duo of HEC researchers, along with a colleague from the University of Texas at Austin, have shown that, to set optimal FIT levels, regulators must take into account the behaviours all players affected, including technology manufacturers.
How big data gives insight into investor uncertainty

Team-building with robots – it works!

“Choice Closure”: An Intervention to Increase Customer’s Satisfaction after a Purchase
This research studies people’s tendency to seek or avoid choice closure with past consumer decisions. Consumers achieving choice closure come to see a decision as finished and resolved. Past research has shown that this sense of choice finality can be externally triggered without consumers being aware of it, for example by asking them to close a menu after selecting one of the featured food items. The current research asks the following questions: What is the effect of choice closure on consumers’ satisfaction following decisions with negative or positive outcomes? Do consumers correctly predict the effect of choice closure on their satisfaction? The answer to these questions allows us to offer insights for marketers and sales people on when and how to use choice-closure triggers as means to enhance satisfaction with the outcome of a decision they have made.
The Impact of Overconfidence and Attitudes towards Ambiguity on Market Entry
For many people who have started their entrepreneurial adventure, the biggest challenge is to believe in yourself. Yet, for those who choose this path, confidence can also make the entrepreneur underestimate actual business risks, leading to fatal decisions. Researchers of HEC Paris Business School and Bocconi University offer a new explanation for why decision-makers often appear too confident, and shed light on the consequences of this characteristic.
Change in E.C.B. communication strategy: any improvement?
In September 2019, the European Central Bank (E.C.B.) shifted its forward guidance on rates from short-term calendar-based type to state contingency. This is a form of guidance that relates directly to the state of inflation rather than a specific date. HEC Associate Professor Gaetano Gaballo, argues that this is a positive first move in removing ambiguous policy signals, although more is needed to spur inflation expectations. Gaballo is currently on leave from a post of senior economist at Banque de France after having served as research economist at the E.C.B..
