The Ratio Institute is an independent Swedish research institute focusing on the conditions for enterprise, entrepreneurship and market economy and political change. The institute's infrastructure is financed by the Swedish Free Enterprise Foundation, but various research projects have financiers like the Wallenberg Foundation and the Confederation of Swedish Enterprise. 'Ratio' is Latin for reason.
Ratio was established as a publishing house within think-tank Timbro (a subsidiary of the Swedish Free Enterprise Foundation) in 1978. The Ratio thinktank was founded in 2002, and formed as a non-profit organisation in 2004.
