White house economists overestimated annual economic growth by about 80 percent on average for a six year stretch during Barack Obama’s presidency, according to FreedomWorks economic consultant Stephen Moore. Keynesian economic thought dominated Obama’s economic policy after the Great Recession, economics professor Richard McKenzie wrote for the Foundation of Economic Education in 2010. According to Keynesian thought, as money circulates in the economy, the government’s initial investment could multiply to a total economic benefit five or 10 times greater than the original stimulus, McKenzie wrote.
