This paper considers policies for promoting productive investments in the United States, especially as regards the project of building a clean energy economy. The four main policies examined are: 1) Expanding public investments throughout the economy and gaining the crowding-in benefits that will accrue from such investments; 2) Refocusing the successful, but ad hoc, U.S. model of industrial policies; 3) Advancing this agenda of public investments, industrial policy and cooperative/community ownership in ways that benefit all regions of the U.S. equitably; and 4) Promoting cooperative and community-based ownership forms, as alternatives to the private corporation.
