Introduction

US government debt isn't a crisis to Paul Krugman. The Nobel laureate has long argued that history and arithmetic suggest a crisis is unlikely. But does that hold true in other countries around the world? Can they live with the levels of debt that have become the norm, or is there a nasty shock or full-blown crisis in the offing? Krugman joins host Carmel Crimmins to talk global debt, spending and the politics driving decision-making. Plus, we take a ride on a Berlin commuter train for a real world look at the downside of balancing the books.
