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

In my view, the state should be active and work in cooperation with private businesses to spur growth that's sustainable and inclusive. The policy process is about co-creating and co-shaping of markets, creating new opportunities for business investment - and negotiating a better deal for the public too.

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.

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.

With a Trump administration we don't know enough yet to make predictions, but if past behavior is any indication, I am not encouraged.

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.
