The Milken Institute’s fourth annual California Summit provided an opportunity to assemble prominent state leaders in business, policy, philanthropy, and academia to address the issues facing the world’s seventh-largest economy and one of the most diverse populations on the globe. Held December 8, 2015, at the Ritz-Carlton in Marina del Rey, the Summit focused on four key areas that define many of the challenges facing the state: the business climate; the need for opportunities in finance and access to capital, including financial technology; investment in the state’s infrastructure, particularly involving water; and the need to maintain and grow the culture of innovation.
