Capture réglementaire en temps de pandémie by Samira Guennif

“…It is shown that there have been multiple captures around a public good: agency, statutory, corrosive or cultural captures, to draw on the work of Carpenter (2014) developed in a break with those of economic regulation theory. Finally, recommendations are made to strengthen the ODA and limit its vulnerability to capture.…”
