Capital Economics founder Roger Bootle is looking to sell the economic consultancy in deal that could land him up to £50m.
The Daily Telegraph reports Bootle, who owns 68 per cent of the firm, has appointed advisers to prepare a sale of the business.
He has retained corporate finance firm Quayle Munro to work on a strategic review.
The Telegraph reports Bootle is selling up after turning 60 last year. He was paid £1.7m in each of the last two years.
Senior economists Jonathan Loynes and Julian Jessop hold 14 per cent and 7 per cent respectively with staff owning the rest.
Capital Economics made pre-tax profits of £4.9m in 2012 with £3.6m of capital and £4.2m of net cash.
