Green is not just about renewable energy. It's also about creating a new direction for the whole economy. This requires government to step up, not step back, creating the kinds of mission-oriented public organizations that will enable us to tackle climate change - as ambitious as those that got us to the moon. It also requires the financial sector to be less short-term since we know that short-term finance has distorted incentives and directions in areas like biotechnology.

It would be a mistake to overstate the similarities between the Brexit vote and Trump's win - but there are common themes, not least in the rallying cries that the winning campaigns used. They focused on a supposed economic threat posed by outsiders, as immigrants or as trade partners. This fuelling of anxieties underpinned a narrative centered on the need to "regain control," whether of borders or of economic forces.

Our current model of capitalism and the dominant ideas in policy making have led to a failure of investment by both the public and the private sector in the things that drive productivity, and which affect its distribution.

The globalized nature of production and innovation means that the benefits don't necessarily stay in the country where the investments are made.

While infrastructure is of course important, it must be part of a bigger vision. The point is not to simply dig ditches but to steer those investments towards transformational growth.

Brexit has shrunk the market opportunities. Exiting trade deals will do the same for the U.S. Those deals must be actively shaped and governed to make growth more inclusive.

My specific concerns with Trump's plans are that they are likely to investments in infrastructure where the private returns are highest (for example toll roads and bridges) rather than where the public gains are greatest.
