Segue o Relatório Anual do Neri de 2024. O relatório destaca como temos transformado dados e análises em instrumentos de mudança, ampliando o entendimento sobre as desigualdades raciais no Brasil.

How can we seed effectively when network information is limited? A new analysis shows how low-dimensional summary statistics can help us fit a random graph model and target based on whatever attributes we can readily observe. https://buff.ly/3WgLgQp

Historian of fascism here. It was a Nazi salute and a very belligerent one too.

Hi all. I'm Pedro Picchetti from INSPER Institute of Research and Education, in Brazil. My #EconJMP provides a new method for the identification of dynamic causal effects using Instrumental Variables. sites.google.com/view/pedropi...
The instrumental variables (IV) method has been widely studied in cross-sectional settings. However, many practical applications involve panel data, in settings where a unit's treatment status may turn on or off over time. I show that in the presence of dynamic treatment effects, that is, if past treatments affect current potential outcomes, standard methods are no longer valid if the instruments are serially correlated. This paper proposes the nonparametric identification of dynamic causal effects in a potential outcomes framework in which potential outcomes depend on the treatment path taken by a unit through time but the first stage is static, in the sense that at each period the IV only instruments its contemporary treatment. I provide a nonparametric estimator that is unbiased over the randomization distribution and derive its finite population limiting distribution as the sample size increase.

Econometrics was the greatest branding exercise in the history of the social sciences.
