Fresh Dialogues interview, "This jobs summit can't be an empty exercise ... he can't come out with a proposal for $10 or $20 Billion of stuff because people will view that as a joke. There has to be a significant job proposal ... I have in mind something like $300 Billion." Krugman has recently criticized China's exchange rate policy, which he believes to be a significant drag on global economic recovery from the Late-2000s recession, and he has advocated a "surcharge" on Chinese imports to the US in response. Jeremy Warner of The Daily Telegraph accused Krugman of advocating a return to self-destructive protectionism. In April 2010, as the Senate began considering new financial regulations, Krugman argued that the regulations should not only regulate financial innovation, but also tax financial-industry profits and remuneration.

In his June 28, 2010 column in The New York Times, in light of the recent G-20 Toronto Summit, Krugman criticized world leaders for agreeing to halve deficits by 2013. Krugman claimed that these efforts could lead the global economy into the early stages of a "third depression" and leave "millions of lives blighted by the absence of jobs". He advocated instead the continued stimulus of economies to foster greater growth. In a 2014 review of Thomas Piketty's Capital in the Twenty-First Century he stated we are in a Second Gilded Age.

Although he has used New Keynesian theory in his work, he has also criticized it for lacking predictive power and for hewing to ideas like the efficient-market hypothesis and rational expectations. Since the 1990s, he has promoted the practical use of the IS-LM model of the neoclassical synthesis, pointing out its relative simplicity compared to New Keynesian models, and its continued currency in economic policy analysis. In the wake of the 2007–2009 financial crisis he has remarked that he is "gravitating towards a Keynes-Fisher-Minsky view of macroeconomics". Post-Keynesian observers cite commonalities between Krugman's views and those
