On the other hand, Krugman has inexplicably taken up the mantle of crude aggregate-demand management, making it seem that favoring large budget deficits in recent years is also part of progressive economics. (Krugman’s position is sometimes called Keynesianism, but John Maynard Keynes knew much better than Krugman that we should not depend on mechanistic “demand multipliers” to set the unemployment rate.)
另一方面，克鲁格曼令人费解地举起了粗犷总需求管理的大旗，将近几年对大规模预算赤字的支持也说成是进步经济学的一部分。（克鲁格曼的立场有时被称为凯恩斯主义，但凯恩斯远比克鲁格曼清楚，我们不应该依赖机械的“需求乘数”来决定失业率。）他坚持认为，2009年赤字增加的不够，因此无法降低高失业；而2010年以降，赤字更是出现了危险的快速减少之势。
