Original post by BenRyan99If you're looking at the more common type of economic consultancies (micro focused), then the usual candidates are firms like RBB Economics, NERA, Oxera, Frontier Economics, Europe Economics, Compass Lexicon, Brattle Group, Cornerstone, Analysis Group, London Economics, Cambridge Econometrics, CEPA, Vivid Economics, SQW, FTI Consulting, Fideres, Economic Consulting Associates, Oxford Policy Management, Charles River Associates, etc.
Beyond these micro-based consultancies, there are also microeconomic consulting arms of bigger consulting firms such as the big4 (PwC, KPMG, EY and Deloitte), PA Consulting, BDO, RSM, Grant Thornton are just launching their new economic consulting arm so are hiring at all experience levels. The MBB strategy consulting firms also hire some economists but these won't be relevant for an undergraduate summer internship.
