Oi gente (mais economistas)!
Há um tempo eu tenho feito algumas funções de econometria (regressões, testes, painel, VI, modelos binários, séries temporais e avaliações de políticas) no Python e acho que vale a pena compartilhar aqui com vocês!

Including the spike matters. It shrinks, and can even flip, the estimated effect of minimum wage hikes on informal inequality.

We estimate the model on 2003 Brazilian data and use it to study the 60% real rise in the minimum wage from 2003 to 2012. To see how much the spike matters, we fit two versions of the model: one that includes it and one that doesn't.

There, firms set wages along an upward-sloping labor supply curve. Some formal firms are mechanically bound by the minimum; others, in both sectors, anchor to it by choice. Together they generate wage distributions with spikes and missing masses, matching our facts.

In our model, firms differ in productivity and choose a sector: formal firms pay entry costs and follow labor law, including the minimum; informal firms avoid these costs but face weak enforcement. After entry, both compete for workers under monopsonistic competition.

Our explanation is wage-anchoring. The minimum acts as an anchor for pay: it cuts firms' wage-setting costs, signals fair pay, and eases wage adjustment under inflation. So some firms in both sectors find it attractive to post the minimum wage.

Using Brazilian firm- and worker-level microdata, we first document three robust facts: (i) bunching at the minimum among formal workers; (ii) the same bunching among informal workers; and (iii) a missing mass just above the minimum, and below it for informal workers.

In developing countries, a significant share of workers are informal and fall outside the scope of labor legislation.
Yet many informal workers still earn exactly the minimum. Why do wee see this bunching of informal workers at the minimum wage?

Setti, @AraujoCRRafael and I just released a WP analyzing the effect of environmental enforcement on the homicide rate in the Amazon.
The paper is here: arxiv.org/abs/2509.06076
Setti is a remarkably bright young economist. Check her website: sites.google.com/view/gabrie….

Como sempre, ótimo artigo do Daniel! Super relevante, ainda mais nas condições fiscais atuais
Um carinho especial porque cita meu trabalho com a @geovanabertussi
Sim, ainda precisamos falar do teto de gastos.

O Vini é um dos principais ícones da luta antirracista no mundo. Se isso não contar como “valor”, diz muito sobre o caráter de quem escreve e de quem publica.
(fora o absurdo futebolístico que é o Vini perder o prêmio pro Rodri)

Muito feliz que minha monografia está para ser publicada na @RevNovaEconomia!
Nela, eu e @geovanabertussi avaliamos alguns efeitos do Teto de Gastos sobre a taxa de investimento público e sobre a Selic.
