These Chroniques Dcales d'un conomiste are a true ode to freedom, a manifesto for optimism in these times marked by a growing declinism. In the tradition of his irreverent Petit Manuel d'conomie, Emmanuel Combe returns to share his thoughts with us through more than a hundred columns that sweep up, with humor and impressive precision and accessibility, all of the themes that have made the news. Climate, energy, digital technology, international conflicts, but also the COVID-19 pandemic, are some of the themes deciphered by the author, who invites us, at the turn of a news item, to a true reflection on the economic mechanisms at work in our society.
