After the Greek crisis, it's time for a new deal on debt

There would have been risks in restructuring Europe's debt, but running those risks would have been well worth it

The International Monetary Fund's acknowledgement that Greece's debt is unsustainable could prove to be a watershed moment for the global financial system. Clearly, heterodox policies to deal with high debt burdens need to be taken more seriously, even in some advanced countries.

Ever since the onset of the Greek crisis, there have been basically three schools of thought. First, there is the view of the troika (the European Commission, the European Central Bank, and the IMF), which holds that the eurozone's debt-distressed periphery (Greece, Ireland, Portugal, and Spain) requires strong policy discipline to prevent a short-term liquidity crisis from morphing into a long-term insolvency problem.
