Are there signs of a Schumpeterian process in recessions?

It is sometimes claimed that recessions trigger a Schumpeterian process, where the disappearance of inefficient companies and other companies’ modernisation effort lead to increased productivity gains. The COVID crisis will definitely eliminate weak companies and speed up the digitisation of the economy. Have there been signs of a Schumpeterian process during and after recessions in the past (in the United States and the euro zone)? We look at: Investment in new technologies and automation; Changes in productivity, by sector and overall (as there may also be a distortion of the sectoral structure of the economy); Changes in profitability and in the return on capital (which must increase if inefficient companies disappear). We conclude that: There are signs of a Schumpeterian process in the wake of the 2008-2009 subprime crisis in the United States, and not in the euro zone; But not enough to prevent productivity gains from declining .
