Releasing open data fuels economic activity, creating value in both the public and private sector. Research from McKinsey suggests that seven sectors could generate more than $3 trillion a year in additional value as a result of open data, which is already giving rise to hundreds of entrepreneurial businesses and helping established companies to segment markets, define new products and services, and improve the efficiency and effectiveness of operations. While governments looking for economic outcomes from open data must focus on releasing assets with business value, the reach of that category across sectors is quite broad, as new research from New York University (NYU) makes clear.
