We're at a critical juncture in our global economy. Gone are the siloed structures of the past where the public and private sectors functioned separately, rarely cross-pollinating to share ideas and models for addressing big problems and creating value. And for good reason.

In The Solution Revolution, Deloitte's William Eggers and Paul Macmillan identify an accelerating shift toward a new operating paradigm, in which entrepreneurship and innovation range freely across all of the sectors that shape our lives as citizens and consumers. This shift offers a powerful spring of hope for public innovation in an era of financial constraints.
