Patricia Sulser, investment committee member at BlueOrchard and former chief counsel at International Finance Corporation, joins Sarah Devine and Rebecca Abou-Chedid for a conversation about public private partnerships (PPPs). We discuss how PPPs are used in the financing of projects in emerging markets and unpack several successful PPP transactions. We also delve into impact investing and blended finance – what these terms mean, how blended finance transactions are structured and how the concept can be used to scale up PPP investment in critical infrastructure in emerging markets.
