Parsing

The Parsing submodule provides macros used for automatic code generation, structs, indexes, etc. These map, e.g., deviations from steady state of aggregate variables to equations lines in the non-linear difference equation that describe the economy.

Collect variables: macros

BASEforHANK.Parsing.@writeXSS — Macro

@writeXSS()

Write all single steady state variables into vectors XSS / XSSaggr.

Requires

(module) globals state_names, control_names, aggr_names

source

BASEforHANK.Parsing.@make_fn — Macro

@make_fn(fn_name)

Create function fn_name that returns an instance of struct IndexStruct (created by @make_struct), mapping states and controls to indexes inferred from numerical parameters and compression indexes.

Requires

(module) global state_names, control_names

source

BASEforHANK.Parsing.@make_fnaggr — Macro

@make_fnaggr(fn_name)

Create function fn_name that returns an instance of struct IndexStructAggr (created by @make_struct_aggr), mapping aggregate states and controls to values 1 to length(aggr_names) (both steady state and deviation from it).

Requires

(module) global aggr_names

source

BASEforHANK.Parsing.@make_struct — Macro

@make_struct(struct_name)

Make struct struct_name with two fields for every variable name in s_names (state variables) and c_names (control variables), together with fields for distribution-states and marginal value function-controls.

Requires

(module) globals state_names, control_names

source

BASEforHANK.Parsing.@make_struct_aggr — Macro

@make_struct_aggr(struct_name)

Make struct struct_name with two fields for every variable name in aggr_names (for steady state value and for deviation from it).

Requires

(module) global aggr_names

source

BASEforHANK.Parsing.@generate_equations — Macro

@generate_equations()

Write out the expansions around steady state for all variables in aggr_names, i.e. generate code that reads aggregate states/controls from steady state deviations.

Equations take the form of (with variable r as example):

r = exp.(XSS[indexes.rSS] .+ X[indexes.r])
rPrime = exp.(XSS[indexes.rSS] .+ XPrime[indexes.r])

Requires

(module) global aggr_names
