Maris was a great admirer of John Maynard Keynes, to whom he devoted a book, Keynes ou l'économiste citoyen and has published many popular economics books. It is known, inter alia, by titles such as Ah Dieu! Que la guerre économique est jolie! (1998), Lettre ouverte aux gourous de l'économie qui nous prennent pour des imbéciles (1999) and La Bourse ou la vie (2000).
With incisive style, he tried to understand the nature and the interests of the real economy, unveiling its negative aspects, but highlighting the concepts and alternatives such as the gratuity and the gift economy, which are, in his eyes, of significance.
Le Nouvel Économiste magazine assigned him the title of "Best Economist of the Year", in 1995.
QuoteOn the euro zone, Bernard Maris is thus expressed in Charlie Hebdo on 15 December 2010:
"Myself, I think there will be a new financial crisis, the eurozone will burst, that Europe will balkanize - she is already balkanized. But a number of events which have arisen over the last ten years were not predictable: The financial crisis, could it really be foreseen? The Twin Towers?"
