...Matthieu Ballandonne The linear model of innovation, which assumes a unidirectional and non-simultaneous relationship between the two realms of science and technology, is still a debated framework. The aims of this article are to show—in contrast with the received view—that economists of science...

... at that controversy from the perspective of MIT, trying to establish why Samuelson and Solow became so involved.
