    Raghuram G. Rajan

    If the new "industrial strategy" is offering ideas for better public governance, it is useful. But it becomes positively dangerous when it turns to the private sector, where state interventions inevitably undermine competition, disrupt price signals, and dampen the motivation to innovate.

    sees little reason to support the case for renewed government interventions in the private sector.
