“Innovation – identified by MIT economist and Nobel laureate Robert Solow as the driver of long-term, sustainable economic growth and prosperity - has been a hallmark of the Massachusetts Institute of Technology since its inception.” Thus starts The MIT Innovation Initiative: Sustaining and Extending a Legacy of Innovation, the preliminary report of a yearlong effort to define the innovation needed to address some of the world’s most challenging problems. Released earlier this month, the report was developed by the MIT Innovation Initiative, launched a year ago by MIT President Rafael Reif.
