This Epilogue provides a reassessment of Keynes's legacy today compared to the last decade of the twentieth century. Recent ideas of what was significant in Keynes, and his legacy, have now shifted. There are five key topics through which this can be viewed: the role of uncertainty, the debate about stimulus, global imbalances, the notion of a Keynesian political economy, and a new economics. A twenty-first century conclusion is that there is a greater need now for more government management of the economy. This in turn needs an intellectual rehabilitation of the state as a potentially rational economic actor, rather than as a vote-seeker.
