The Bra­zi­li­an Micro­Si­mu­la­ti­on Model, or BRASMOD, is the first lar­ge-sca­le, open-access, tax, and bene­fit sys­tem micro­si­mu­la­ti­on model for Bra­zil, built within the well-esta­blished EUROMOD soft­ware. The model covers a sig­ni­fi­cant por­ti­on of Bra­zil’s tax and bene­fit struc­tu­re, such as the Bol­sa Famí­lia Pro­gram, Unem­ploy­ment Insu­ran­ce, and Direct and Indi­rect Taxes, among others.

All codes and data used in the model are avai­la­ble on the BRASMOD GitHub page, and the docu­men­ta­ti­on regar­ding the adop­ted assump­ti­ons and metho­do­lo­gi­cal choi­ces can be found in the Coun­try Report [link here].

The micro­da­ta used in BRASMOD were extrac­ted from the Nati­o­nal Hou­sehold Sam­ple Sur­vey (PNAD) until 2015 and from the Con­ti­nu­ous Nati­o­nal Hou­sehold Sam­ple Sur­vey (PNADc) after that. The PNAD and PNADc are the main hou­sehold sur­veys con­duc­ted by the Bra­zi­li­an Ins­ti­tu­te of Geo­graphy and Sta­tis­tics (IBGE). The model also incor­po­ra­tes data from the Hou­sehold Bud­get Sur­vey (POF) for 2008 and 2018.

BRASMOD aims to ser­ve as a tool for demo­cra­ti­zing and pro­mo­ting the use of micro­si­mu­la­ti­on for public policy eva­lu­a­ti­on, faci­li­ta­ting gene­ral unders­tan­ding, and impro­ving policy design. BRASMOD was deve­lo­ped through a part­nership betwe­en Made and the Labo­ra­tory of Public Sec­tor Eco­no­mics (Lab­pub) at USP. Its deve­lop­ment was sup­por­ted by the Fun­da­ção Ins­ti­tu­to de Pes­qui­sas Econô­mi­cas (Fipe), Samam­baia Phi­lanth­ro­pi­es, Wells­pring Phi­lanth­ro­pic Fund, Open Soci­ety Foun­da­ti­ons, and the Hewlett Foundation.
