How do affluent people behave in a crisis? In 2009, Séissmo owner Natacha Dagneaud received an Executive MBA from Kellogg School of Management / Northwestern University in Chicago (USA). This study corresponds to her final thesis which looks at what impact the financial crisis, which began in 2007, has had on consumer behaviour of the top earners in 6 countries: The US, England, France, Germany, Russia and China. Is it still appropriate to show consumption or should it be avoided? The study combines qualitative in-depth interviews with top earners from all six countries as well as the results of a follow-up online survey of 600 participants.
