Euromod Connector

What is Euromod?

The Euromod Connector for Python is built to facilitate and simplify the usage of the EUROMOD microsimulation model for research and analysis purposes.

EUROMOD is a tax-benefit microsimulation model for the European Union that enables researchers and policy analysts to calculate, in a comparable manner, the effects of taxes and benefits on household incomes and work incentives for the population of each country and for the EU as a whole. It is a static microsimulation model that applies user-defined tax and benefit policy rules to harmonised microdata on individuals and households, calculates the effects of these rules on household income.

Installation

Install via PyPi using pip:

$ pip install euromod

Requirements

The Euromod Connector requires two EUROMOD components: 1) the model (coded policy rules) , and 2) the input microdata with the variables that respect the EUROMOD naming conventions. For more information, please, read the sections "Model" and "Input microdata" on the Download Euromod web page.

Run simulation

Importing and loading the model:

In[1]: from euromod import Model
In[2]: mod=Model(r"C:\EUROMOD_RELEASES_I6.0+")

Loading the dataset using pandas:

In[3]: import pandas as pd
In[4]: data = pd.read_csv(r"C:\EUROMOD_RELEASES_I6.0+\Input\sl_demo_v4.txt",sep="\t")

Running a simulation on system 'SL_1996' of the country Simpleland 'SL' (Note: this country model is provided by default with the EUROMOD project):

In[5]: out=mod.countries['SL'].systems['SL_1996'].run(data,'sl_demo_v4')
In[6]: out.outputs[0]
