The Adam Smith Institute was long a favorite of Maggie Thatcher, Ronald Reagan and the Conservative Party, "as the founder of free market economics".
It is Britain's leading innovator of free-market economic and social policies. Named after the great Scottish economist and author of The Wealth of Nations, the Institute is guided by the principles of the free society.
