The market will not, on its own, solve any of these problems. Global warming is a quintessential “public goods” problem. To make the structural transitions that the world needs, we need governments to take a more active role – at a time when demands for cutbacks are increasing in Europe and the US.
As we struggle with today’s crises, we should be asking whether we are responding in ways that exacerbate our long-term problems. The path marked out by the deficit hawks and austerity advocates both weakens the economy today and undermines future prospects. The irony is that, with insufficient aggregate demand the major source of global weakness today, there is an alternative: invest in our future, in ways that help us to address simultaneously the problems of global warming, global inequality and poverty, and the necessity of structural change.
