Innovation in the United States, once a hallmark of economic success, finds itself resting on an increasingly weak foundation, according to an article in The New York Times. The author, Eduardo Porter, suggests that two trends – increased international competition and a stagnant R&D-to-GDP ratio – pose key challenges for the U.S. First, government funding for basic research continues to fall and is politically vulnerable. Second, evidence suggests that American corporations are walking away from basic science as well. Each of these challenges, Porter notes, bodes poorly for American progress. Using a variety of data sources, this Digest series provides a long-term analysis to assess how basic research has changed over time within the larger context of research and development in the United States.
