Exploiting Model Structure to Solve the Dynamics of a Macro Model

This paper considers alternative approaches to solving the time-path of a representative agent model following an exogenous shock. The model has a number of important dynamic properties that are both common to a wide range of economic models and have important computational implications for solving the model. The paper compares the alternative approaches on a computational basis and shows that the best approach to solving the model is obtained by fully exploiting the model structure in a modified reverse shooting algorithm.
