This course will provide students an opportunity to author a publishable-quality case study on a set of topics related to sustainable cities and urban systems. The first part of the course will include a review of existing case studies from the Harvard Business School and other case study programs, followed by a methodological review of what makes a good case study. The second half of the term will focus on the research and development of one new case study by each student (or student team) focused on the core issues of integrated planning and economic, environmental, and social trade-offs of specific urban sustainable development challenges. The final products of this course will be a set of case studies; the top papers from the Spring and Fall semesters are anticipated to be compiled into an edited volume for publication.
