The inaugural article of Reviews of Economic Literature is fittingly titled

"It Is Time to Bring Scholarly Publishing Back to the Academic Community"

It argues that open access crucially needs to be coupled with a new non-profit publishing model

LP-DiD specifications can reproduce other recent DiD estimators (see @arindube.bsky.social's thread below).

More in general, the LP-DiD framework can be tailored to specific settings, by properly writing the “clean control condition" that defines treated & control units.

LP-DiD specifications can estimate either a variance-weighted ATT (no negative weights) or the equally-weighted ATT.

It is easy to include covariates and to deal with non-absorbing (ie, repeated) treatment.

Gives either an event study or a pooled estimate averaged over posttreatment period

Our Local Projections Difference-in-Differences (LP-DiD) paper is out in the Journal of Applied Econometrics.

LP-DiD is a convenient, flexible and computationally fast framework for estimating DiD using simple well-specified regressions....

My piece "The Neoclassical Theory of Aggregate Investment and its Criticisms" is now out

Neoclassical investment theory implicitly or explicitly underlies much formal or informal economic reasoning.

Here I offer a systematic perspective on its mechanisms & difficulties

Yeah that’s exactly what the ‘pre-mean differenced’ LP-DiD specification that is very close (although not identical) to the BJS estimator does.

New updated slides deck about Local Projections Difference-in-Differences (LP-DiD)

LP-DiD is a fast and simple to implement regression-based framework for estimating DiD, which can reproduce popular recent estimators as specific instances.

Economists tend to see "labor exploitation" as an old-fashion, incoherent, metaphysical idea.

Our new paper argues that-to the contrary-labor exploitation can be given a precise, consistent definition and taken to the data, estimating its distribution in the US.

Research Assistantship opportunity for Brazilian (or living/studying in Brazil) MA/PhD Economics students.

We are hiring a RA to support with empirical work in Economics/Applied Econometrics. Expertise in econometric theory would be a big plus. Apply ASAP!

The concept of 'populism' does not mean much and creates much more confusion than clarity, exhibit 1,522:

What is it supposed to mean that Pope Francis was "influenced by his Latin American populist roots"? (NYT).

Not an isolated case IMO: resort to "populism" often leads to this nonsense.

⚠️Mass resignation of the Editorial Board of the Journal of Economic Surveys.⚠️

In our view, the policies that Wiley is imposing on JoES entail serious risks of proliferation of poor-quality science.

Does studying economics make you selfish and conservative?

Our article using lab experiments in a DiD design to investigate this question is now available (open access) at SEJ

In our sample, we found little effect on social preferences & policy opinions.
