Extending BeforeIT using macros and multiple dispatch

Extension by Specialization

import BeforeIT as Bit
using Plots

When extending the BeforeIT model it is required to first create a new model type to use instead of the default model, we can do so by using

Bit.@object struct NewModel(Bit.Model) <: Bit.AbstractModel end

In BeforeIT, new objects can be created to add new behaviours. For instance, we can define a new central bank object with one extra attribute

Bit.@object mutable struct NewCentralBank(Bit.CentralBank) <: Bit.AbstractCentralBank
    fixed_rate::Float64
end

and then change the default central bank behaviour for the new type

function Bit.central_bank_rate(cb::NewCentralBank, model::Bit.AbstractModel)
    return cb.fixed_rate
end

Now, we can initialize the model to include the new type, to do so, we will need to initialize all model components first

p, ic = Bit.AUSTRIA2010Q1.parameters, Bit.AUSTRIA2010Q1.initial_conditions
firms = Bit.Firms(p, ic)
w_act, w_inact = Bit.Workers(p, ic)
cb = Bit.CentralBank(p, ic)
bank = Bit.Bank(p, ic)
government = Bit.Government(p, ic)
rotw = Bit.RestOfTheWorld(p, ic)
agg = Bit.Aggregates(p, ic)
properties = Bit.Properties(p, ic)
data = Bit.Data()

BeforeIT.Data(Int64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Float64[], Vector{Float64}[], Vector{Float64}[])

And then initialize a new central bank with the same fields as the original one, and the fixed interest rate

new_cb = NewCentralBank(Bit.fields(cb)..., 0.02)

standard_model = Bit.Model((w_act, w_inact, firms, bank, cb, government, rotw, agg, properties, data))
new_model = NewModel((w_act, w_inact, firms, bank, new_cb, government, rotw, agg, properties, data))

After that, we simulate both models

T = 20
model_vec_standard = Bit.ensemblerun(standard_model, T, 4);
model_vec_new = Bit.ensemblerun(new_model, T, 4);

And plot the results

using Plots, StatsPlots
ps = Bit.plot_data_vectors([model_vec_standard, model_vec_new], quantities = [:euribor, :gdp_deflator])
plot(ps..., layout = (1, 2), size = (600, 300))

Extension by Invocation

First, we create as before a new model type

Bit.@object struct NewModel2(Bit.Model) <: Bit.AbstractModel end

Now, let's say that one wants to track the number of employees in the economy, something not included by default when running a simulation. To do so, we create a new data type with

Bit.@object mutable struct MoreData(Bit.Data) <: Bit.AbstractData
    N_employed::Vector{Int} = Int[]
end

We then need to specialize the function Bit.update_data!, and, at the same time, invoke the default tracking because we don't want to lose the information on the other variables

function Bit.update_data!(m::NewModel2)
    @invoke Bit.update_data!(m::Bit.AbstractModel)
    push!(m.data.N_employed, sum(m.firms.N_i))
    return m
end

We then initialize the model as usual

firms = Bit.Firms(p, ic)
w_act, w_inact = Bit.Workers(p, ic)
cb = Bit.CentralBank(p, ic)
bank = Bit.Bank(p, ic)
government = Bit.Government(p, ic)
rotw = Bit.RestOfTheWorld(p, ic)
agg = Bit.Aggregates(p, ic)
properties = Bit.Properties(p, ic)
mdata = MoreData()
new_model = NewModel2((w_act, w_inact, firms, bank, cb, government, rotw, agg, properties, mdata))

Bit.run!(new_model, T);

Finally we can plot the new data

plot(new_model.data.N_employed, label = "Employed Workers")
