The UK – Researcher Practitioner Network for the Economics of Digitization:

Date: 25 Nov 2022

Location: Norwich, University of East Anglia

Format: in Person

Local Organizers: Michael Kummer (UEA and CCP); Peter Courridge (UEA and CCP); Sean Ennis (UEA and CCP)

Background and objective:

This initiative tries to connect research about the Economics of Digitization to policy and managerial practice. The idea is to create a network that gets researchers and practitioners to talk to each other, by meeting once a year and doing two things: 1.) Present recent (hot!) research about the economics of digitization and 2.) Receive feedback and input from practitioners where they would need more useful answers from the research community.
