Brexit and Trump's election are forcing countries to come up with new radical ideas.

Shareholder value theory - the destructive idea that companies should be run solely for the benefit of shareholders - has led to financialized businesses that do not invest in the areas that will lead to future growth or the invention of useful new products.

Too many politicians seem to reach for 'infrastructure' as the default answer to investment, as if roads and bridges were the answer to everything. Even the IMF and the World Bank seem to mainly offer infrastructure spending as an alternative to austerity, although they are right to focus on the need for investment.

Companies prefer to put money in the pockets of shareholders or to hoard cash rather than to raise wages or invest.

Real median household incomes in the U.S. were basically the same in 1989 as in 2014. But we are also seeing similar challenges in the U.K. in the stagnation of real wages.

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

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.
