Keynesian(redirected from Keynes, John Maynard, 1st Baron)
Also found in: Dictionary, Thesaurus, Encyclopedia.
A scholar or other person who believes that government intervention is necessary to ensure an active and vibrant economy. According to this theory, government should stimulate demand for goods and services in order to encourage economic growth. It thus recommends tax cuts and increased government spending during recessions to reinvigorate growth; likewise, Keynesians recommend tax increases and spending cuts during economic expansion in order to combat inflation. Many economists believe that Keynesian economic theory is more efficient than supply-side economics, though critics point to the theory's inability to explain stagflation in the United States during the 1970s.
