Instead, we should map out a forward-looking plan based on reasonable assumptions about the primary surpluses consistent with the rates of output growth, net investment, and export expansion that can stabilize Greece’s economy and debt ratio. If this means that the debt-to-GDP ratio will be higher than 120% in 2020, we devise smart ways to rationalize, re-profile, or restructure the debt – keeping in mind the aim of maximizing the effective present value that will be returned to Greece’s creditors.
