Time Representation in Economics

In this paper, we study general polynomial discretizations in backward and forward looking, and the preservation of

stability properties. We apply these results to the Ramsey model [1]. Its discrete-time version is a hybrid discretizations of

a backward-looking budget constraint and a forward-looking Euler equation. Saddle-path stability is a robust property

under discretization.
