Who’s afraid of the Euro crisis?

What are the possible ripple effects of the euro crisis? There are a myriad of different opinions about what might happen and how far it might go.

This interactive graphic from the BBC website is a neat summary of just some of them - it starts with Greece itself, with comparisons to the debt crises in Spain, Portugal and Ireland then looks at the potential contagion effects of a collapse of confidence in Italy.

This may spread to banking meltdown in France, the UK and the ECB, with a Euro break-up rippling through the German and wider EU economies. As a result of the interdependence of the EU and its worldwide trading partners, global meltdown follows - which explains why Christine Lagarde of the IMF has been calling for more leniency towards Greece and other borrowers, and more action in Europe to boost growth.

Is there some way in which such negative multiplier effects can be avoided? Can macroeconomic policies be used somehow to protect domestic economies from the fallout? If they cannot, what next? This resource only presents one set of ideas, but might just help students to tease out some of the convoluted and complex issues which dog the EU and global economy at present.
