This article is good evidence for the efficacy of tax cuts in stimulating OECD economies and against the efficacy of Keynesian government spending stimulus. In my opinion,Keynesian stimulus (but not income redistribution) should be reserved for historically rare periods of economic panic when consumer and business spending is severely depressed and government spending increases are needed to take up the slack.
