Plan in the dark.

Summary The current crisis is not only sanitary, it is also economic: confinement is an obstacle to certain consumption practices but also to an important part of the productive activity. The situation prompts comparisons with the great recessions or depressions of the past: some indicators recall the 2008 crisis, others the one that began in 1929... But such parallels leave many questions unanswered: to what depths will the health crisis precipitate the world economies, and the French economy in particular? Will the announced recession be short-lived or, on the contrary, long-lasting? The Covid-19 epidemic is ushering in a period of great uncertainty that requires the production of forecasts, which it paradoxically makes more difficult.
