Institute of Economic Affairs - London | 12,343 followers on LinkedIn. The UK's original free-market think-tank! | The IEA is the UK's original free-market think-tank, founded in 1955. Our mission is to improve understanding of the fundamental institutions of a free society by analysing and expounding the role of markets in solving economic and social problems. Given the current economic challenges facing Britain and the wider global environment, it is more vital than ever that we promote the intellectual case for a free economy, low taxes, freedom in education, health and welfare and lower levels of regulation.
