It is not easy to say something relevant when it comes to comments the legacy of a prominent economist .Thus, maybe it is better to side step. But ,I am an economist just like Paul Samuelson. Sure, I am not a genius like him ,but I am fully capable of understanding the magnitude of his legacy . I studied with his books, my basic notions of economics.
Like many other great economist once they pass away, the real issue becomes not just theirs contribution , but how it fit properly with the times. Let checks some examples: Michael Kalecki was a polish economist(socialist) ,who stated the foundation of Government intervention into the economy(1933) , just like Keynes (Liberal)did a few years later(1936). However, they had a different impact with this approach of Government activism. While Keynes has been widely considered the founder of macroeconomics, Kalecki is barely known outside the academic circle .Rudiger Dornbusch, a German born economist, who helped to reshape the financial implication of both capital mobility and monetary policy impact on exchange rate(overshooting effects), and along with it , the foundations of the normative macroeconomics , did not get the same recognition and impact as Robert Mundell got, who even rised himself up, above his colleague and mentor, Fleming . Thus, great economists with outstanding contributions do not get always the recognition they deserve .That was not the caser of Paul Samuelson .
Is it a matter of luck?. I think it is more a matter of timing. To be on time with history and its requirements , neither sooner nor later, but just in time. Knowledge is the input of economic progress and society welfare, and like any input its usefulness is higher when it is available at the right time, where it is most needed and with the format more comprehensive to all. Friedman ,although not the first one to call the attention upon the inflationary impact of money growth ,was also on time to cope with the implications of both Fiscal and monetary expansion.His contribution, cames along when Governemnet intervention and fiscal expansion were considered as the conventional wisdom. Therefore, it is the proper combination of the man ,the time and the knowledge which provides, which make the most of brilliant ideas.-
Paul Samuelson contribution was wide and diverse. It was famous his explanation of stock fluctuations and its ability to anticipate recession. “They had anticipated nine of the last five recessions” ,he said in a TV interview in the eighties. Beyond what it is at the surface, he was sceptics about markets and its ability to solve the cyclical fluctuations ,which make him an icon of Government interventionism. However ,Did he had the last words about it?.-
