We discuss long-run properties of Leontief input-output systems that are subject to technical change. We derive a necessary and sufficient condition on changes in input coefficients for the economy to remain productive for all time. We define Harrod-neutral change in Leontief systems, and show that, under specified conditions, Harrod-neutral change increases output possibilities asymptotically as quickly as any alternative form of technical change.
