Starting point of this policy memo (7 pages) issued August 2013 is the opinion that the terms competitiveness, innovation and productivity "are often used almost interchangeably and with little precise meaning" (p. 2). After describing these terms (pp. 2 - 5) the author presents some implications for policy (pp. 5 - 6): "To truly succeed in today’s technology-driven, global economy nations need to develop three distinct strategies: one for success in innovation, one for international competitiveness and one for productivity. Not only will this lead to success in each of the three realms, it will lead to reinforcing policies that benefit all three factors and drive economic prosperity and quality of life." (p. 6)
