Explaining the Euro crisis: current account imbalances, credit booms and economic policy in different economic paradigms

The paper proposes a post-Keynesian analysis of the Eurozone crisis and contrasts interpretations inspired by New Keynesian, New Classical, and Marxist theories. We analyze the role different paradigms attribute to current account imbalances, fiscal policy and monetary policy. Remarkably, opposing views on the relative importance of cost and demand developments in explaining current account imbalances can be found in both heterodox and orthodox economics. Regarding the assessment of fiscal and monetary policy there is a clearer polarization, with heterodox analysis regarding austerity as unhelpful and large parts of orthodox economics endorsing it. We conclude that there is a weak mapping between post-Keynesian, New Classical, New Keynesian and Marxist theories and different economic policy strategies for the Euro area, which we label Keynesian New Deal, European Orthodoxy, Moderate Reform and Progressive Exit respectively.
