*Reading the above see it is actually 163 signatories^
The link is a bit misleading; "the 163 economists from top institutions", "the notable economists", "the top economists"
- at least half are not from top institutions at all - 15 teach at the University of Greenwich, 6 at the Open University, others at Kingston, Huddersfield, Wolverhampton, Herts, Northampton, East London, West of England etc.
Quite a few appear to be EU citizens - conflict of interest? The article says they are against a 'hard Brexit'.The remainder are probably left-wing academics, even if they are considered to be notable economists.
I googled 5 of them:
Dr Giorgos Galanis has studied Mathematics and Economics at the Universities of Athens.
Dr Alberto Botta holds a BA with laude in Political Sciences at University of Pavia.
Mehmet Ugur In addition to curriculum development for and teaching of undergraduate and postgraduate courses, he has led and managed research projects funded by the European Commission.
Carolina Alves Macroeconomics, Money, Monetary and Fiscal Policy, Public Debt, Financialisation, Marxist Economics and Latin America.
Professor Cumbers will receive €1.76m [2018 European Research Council Advanced Grant] for his five-year project to investigate remunicipalisation, a global trend for cities to take formerly privatised assets, infrastructure and services back into public ownership.
