The computation of large-scale nonlinear intertemporal optimization problems requires time aggregation. A procedure generally adopted is shown to introduce a dependency of the solution steady state to a specific choice of sequence of time intervals. The authors establish necessary and sufficient...

In this paper, the authors study a general concave discrete-time, infinite-horizon, optimal-control problem. They establish necessary and sufficient conditions for optimality in the weak sense of W. A. Brock and for optimality in the strong sense of D. Gale. The corresponding transversality...
