Qmod: A Python class implementing the Abel-Hayashi "Marginal Q" model of investment.

This implementation follows Professor Christopher D. Carroll's lecture notes.

1. Qmod

The Qmod folder includes a file defining the Qmod Python class, which represents a Q-model of capital investment. The Qmod class' current functions include:

• Solution of the model, obtaining its policy rule.
• Drawing of the model's phase diagram.
• Simulation of the model's dynamics starting from a given level of capital.

2. Dolo

The Dolo folder implements the model using Dolo.

3. Examples

Current examples include:

• Qmod_basic_features: illustrates how to use Qmod and its main functions.
• Dolo_simulations: uses Dolo to conduct more complicated simulation exercises that could not be easily achieved using Qmod.
• Structural_changes_Qmod_Dolo: solves the dynamic exercises in Professor Christopher D. Carroll's lecture notes using both Qmod and Dolo.
