Redistributing wealth to families the advantages of the MYRIADE model

International audienceThis study aims to shed light on the main characteristics of the French system for redistributing wealth to families through tax revenues and social transfers. For the purposes of this exercise, the authors used the MYRIADE microsimulation model, which covers most of the redistribution system, though it is limited to monetary flows such as family benefits, housing allowances, minimum social welfare payments, income tax, and tax on furnished accommodation. The authors used a particular methodology to highlight the way this redistribution works; rather than calculate the difference between each family's disposable income and their gross primary income, they opted to isolate the variation in disposable income that could be attributed to the youngest member of each family where there is at least one child under the age of 25. The average increase in disposable income that this child contributes to his or her family amounts to 200 EURO per month
