The .mod language

A .mod file is a sequence of blocks describing the model, its steady state, its initial conditions and the exogenous paths, plus the commands that drive the solver. The order of blocks is largely free — the parser is order-insensitive — but the conventional order, used in all shipped examples, is

1. variable and parameter declarations,

2. parameter values,

3. the model; block,

4. initval; (and optionally initial_guess;),

5. steady_state_model;,

6. shocks;,

7. one or more commands (simulate;, steady;).

Comments are written with // (line) or /* … */ (block), exactly as in Dynare.

This part of the manual documents each construct in turn:

• Declarations
• The model block
• The steady_state_model block
• Initial conditions: initval and initial_guess
• The shocks block
• Commands
• Expressions
• The macroprocessor
