Book excerpt: There is no precedent to the current economic crisis which looks set to redefine social policy debate throughout the globe. But its effects are not uniform across nations. Bringing together a range of expert contributions, the key lesson to emerge from this book is that 'the crisis' is better understood as a variety of crises, each mediated by national context. Consequently, there is an array of potential trajectories for welfare systems, from those where social policy is regarded as incompatible with the post-crisis economy to those where it is considered essential to future economic growth and security.
