A huge thank you to Luis Felipe López-Calva for inviting us @unu-wider.bsky.social to be part of such a rich and inspiring event. This event helped set the stage for the 11th ECINEQ Conference, and we contribute debating how tax data can be used to study poverty and inequality in LMICs

Kicking off @UNUWIDER #WIDERDevConf2025 with powerful insights: 🌍 Social protection is foundational, 💼 employment is the engine of development, and 💡 bold thinking is key in a world of crisis. The urgency for inclusive, evidence-based action has never been clearer.

6/ 🤔 Why the positive response? Yes, we show mechanisms:
Firms likely:
-Resolved regulatory uncertainty
-Anticipated future costs
-No significant rise in R&D
-Only marginal increase in tech-related imports

Encontramos que os efeitos positivos são explicados sobretudo nos cursos relacionados ao setor de servicos e localizados em municípios com bom crescimento econômico, e os maiores efeitos negativos, especialmente durante o periodo do curso, são relacionados aos cursos diurnos.

Também analisamos os efeitos do programa para além do mercado de trabalho, mas não encontramos efeitos sobre empreendedorismo e sobre a probabilidade dos alunos continuarem seus estudos na UFBA. Além disto, a rica base de dados nos permitiu realizar diversas heterogeneidades

E como realizamos esta avaliacão? Utilizamos o fato de o programa selecionar os participantes de forma aleatória. Qualquer ex aluno da rede pública estadual de ensino é elegível ao programa, cerca de 100 mil se inscrevem por ano, e 10 mil são selecionados.

Nossos resultados sugerem que o programa tem efeitos positivos sobre a empregabilidade das mulheres que se graduaram antes da recessão. Contudo, para os dois grupos, mas especialmente para os homens, o programa gera um efeito negativo sobre a empregabilidade durante o curso
