JPMorgan CEO Jamie Dimon gave more details about the partnership between Amazon, Berkshire Hathaway, and his institution in his annual letter to the bank's shareholders, Bloomberg reported. The letter suggests that the timeline will be long and the venture would start small, with priorities focused on aligning incentives among doctors, insurers, and patients; reducing fraud and waste; giving employees more access to telemedicine and better wellness programs; and figuring out why so much money is spent on end-of-life care. He also said the partnership will use big data and virtual technology.
