COVID-19 has exposed many flaws in our economic systems. Governments are deploying trillions to respond to the pandemic and rebuild economies with unprecedented public spending that will have to be paid for by generations to come. Decisions on how to spend these funds will shape the future.


We face a choice — attempt to prop up an outdated system that has been exposed, or build back a better economy.

Harnessing an Emerging Sector to Build a Better Economy.

For decades millions of pioneering individuals and organizations have been reimagining and remaking systems of finance, enterprise, measurement, policy, production, consumption and more to better serve the common good. Impact investing, social enterprise, ESG reporting, venture philanthropy, circular economy, and blended finance are only a few examples.

This mosaic of innovations, involving countless organizations and networks around the world, is spurring the emergence of a new approach to economy and enterprise that combines the best of the public sector (governments), private sector (for-profit businesses), and third sector (non-profits). This has led to the blurring of the boundaries among these three sectors. Viewed in aggregate, this burgeoning activity constitutes a new, fourth sector of the economy which is estimated to represent as much as 10% of GDP in the U.S. and Europe.

Using a Fourth Sector Lens 

Participants are encouraged to think BIG and outside-the-box. Looking through a fourth sector lens, they can leverage the decades of innovations that have been growing at the intersection of the traditional sectors to imagine and create a better economy for all.
