This exercise does not solve the problem of the EU debt crisis, and raises more questions that it answers in terms of data reliability. However the revelation about how interlinked debt might net out (possibly even to zero) is a policy option. And indeed if this exercise leaves some countries with a large remainder it points to where the real problems are. Either way, it sheds light on the issue and uncovers information. The fact that so much debt is interlinked presents a real opportunity to solve the problem. The web of interlinked debt is too thick to be dusted away by classroom games, however policymakers should attempt to replicate this study, and they may find that instead of spinning further webs they might get out a duster to clean things up.
