## !parameters

List of parameters

#### Syntax

    !parameters
        parameter_name, parameter_name, ...
        ...

#### Syntax with descriptors

    !parameters
        parameter_name, parameter_name, ...
        'Description of the parameter...' parameter_name

#### Syntax with steady-state values

    !parameters
        parameter_name, parameter_name, ...
        parameter_name = value

#### Description

The `!parameters` keyword starts a new declaration block for parameters; the names of the parameters must be separated by commas, semi-colons, or line breaks. You can have as many declaration blocks as you wish in any order in your model file: They all get combined together when you read the model file in. Each parameters must be declared (exactly once).

You can add descriptors to the parameters (enclosed in single or double quotes, preceding the name of the parameter); these will be stored in, and accessible from, the model object. You can also assign parameter values straight in the model file (following an equal sign after the name of the parameter); this is, though, rather rare and unnecessary practice because you can assign and change parameter values more conveniently in the model object.

#### Example

    !parameters
        alpha, 'Discount factor' beta
        'Labour share' gamma = 0.60
