As a businessman, Donald Trump has been associated with some of the worst excesses of a particular style of value-extracting and asset stripping capitalism: set up businesses, let them fail, avoid paying suppliers, use bankruptcy laws to avoid taxes for decades, then set up another business somewhere else. It is this model that is the cause of many problems we see today.

Rethinking capitalism means rethinking the role of the public sector, the role of the private sector, the role of finance, and the relationship between them all.

Fixing markets isn't enough. We have to actively shape and create them and tilt the playing field in the direction of the growth we want.

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.

Once we admit that the public sector takes an immense amount of risk along the entire innovation chain, it becomes crucial to find ways to share both risks and rewards.

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.

Germany is using its Energiewende policy as a way of envisioning a green transformation and innovation across many sectors.
