摘要：The Ramsey model of economic growth is revisited from the point of view of viability. A viable
state is a state from which there exists at least one tra jectory that remains in the set of constraints
of minimal consumption and positive wealth. Viability is presented with a constraint of minimal
consumption, then with an additional criterion of economic sustainability. The comparison of
viability kernels with or without sustainability shows how much consumption should be reduced
and when. The viable-optimal solution in the sense of inter-temporal consumption is obtained on
the viability boundary of an auxiliary system. Technological progress works against population
growth to favor the possibility for a given state of being viable or viable-sustainable.
