While pension plans have traditionally prioritized financial outcomes over other measures of success, an increasing number of plans are integrating social goals into economically targeted investments (ETIs). This new research brief highlights model public and private pension plans and synthesizes best practices, such as maintaining a clear and strategic focus, partnering with local non-profits, and integrating outside subsidies or partnerships with government entities to grow investments. The authors estimate gains from such an approach could direct more than $250 billion in capital toward the impact investing marketplace.
