Interesante reflexión de Barry Eichengreen Our Children’s Economics
"The consensus, in other words, seemed to be that there would be nothing in the next 20 years as transformative as Alfred Marshall’s synthesis of the 1890’s or the revolution initiated by John Maynard Keynes in the 1930’s. In contrast to the economics of those years, economics today is a mature, well-established discipline. And, like any mature discipline, it advances incrementally rather than in revolutionary steps.
This presumption is almost certainly mistaken. It reflects the same error made by scholars of technology who argue that all of the radical breakthroughs have already been made. As this view is sometimes put, the next 20 years will see no breakthrough as revolutionary as the steam engine or the transistor. Technological progress will be incremental rather than revolutionary. Indeed, insofar as the increments are small, the result is likely to be slower productivity growth and a “Great Stagnation.”
