Or, "no one wanted to look at this thing because it's a hot, hot mess, and finally I did, and guess what? It's a hot, hot mess."

"Significant contribution to the field" often translates to "first person to care about this very specific thing"

I recommended a rejection of a paper because a key reference, mentioned 7 times as a closely related work with a similar methodology, simply does not exist. It was supposedly written by some plausible authors, with a plausible title, in a plausible journal, but it does not exist. Weird feeling...

1. The philosophy of science sometimes gets an unearned reputation as a purely academic exercise that offers little by way of concrete tools for advancing research.

This is wrong.

And today, as we grapple with how AI is changing the nature of scientific activity, it's desperately wrong.

Our research was featured on @voxdev.bsky.social!

@olihanney.bsky.social, @emaansiddique.bsky.social and the stellar editorial board do a fantastic job in offering curated, accessible materials to the development research community.

As a devoted reader, I am very happy to have contributed to it :)

🆕 Understanding self-employment in Brazil: Can people afford to search for jobs?

Today on VoxDev, @tscarelli.bsky.social and David Margolis show that material scarcity and financial constraints appear to be the main drivers of self-employment in Brazil: voxdev.org/topic/labour...
Understanding self-employment in Brazil: Can people afford to search for jobs?
Material scarcity and financial constraints appear to be the main drivers of self-employment for approximately two-thirds of urban own-account workers in Brazil.

12\ I would like to extend my gratitude to all my colleagues who provided feedback on earlier versions of this work. Finally, to the anonymous referees whose valuable insights helped shape this final version -- if you are reading this, thank you!
tscarelli.bsky.social
11\ Why this matters

This result challenges some narratives about entrepreneurship in developing countries by presenting evidence that a large majority of own-account workers appear to be people making constrained choices in a context of frictional labour markets and immediate financial pressures.
tscarelli.bsky.social
10\ Intuitively, for workers facing urgent consumption needs without access to credit, immediate (though lower) income becomes the only viable option.
tscarelli.bsky.social
9\ That is how we conclude that 1/3 of the Brazilian own-account workers appear to be taking their first-best economic choice. By contrast, twice as many seem to be favouring the immediate gains from own-account work at the expense of much larger gains in terms of future wages.
tscarelli.bsky.social
8\ This comparison tells us how intense the constraints faced by own-account workers are, as it provides the lowest level of financial urgency (or discount rate) that explains the choices observed in the data. We then compare it with the discount rates available in the credit market.
tscarelli.bsky.social
7\ Intuitively, we assume people compare the flow of earnings from their own-account work with a (potentially higher) flow of earnings from a wage employment that would start sometime later in the future.
tscarelli.bsky.social
6\ Also, finding a job takes time! So, we need an estimation of how long it takes for people to find a wage position. The time dimension is fundamental here since taking wages at face value would exaggerate the relative gains of wage employment.
tscarelli.bsky.social
5\ First, people are different in many dimensions, so we need to adjust for that when we estimate the potential (counterfactual) wages of own-account workers.
tscarelli.bsky.social
4\ How do we answer this question?

In simple terms, we present a comparison between the economic returns of own-account work versus wage work, taking into consideration a few complications in the process.
tscarelli.bsky.social
3\ In practice, it is hard to distinguish whether most own-account workers are motivated by the opportunities or constrained by the circumstances. This paper proposes one way of doing that.
tscarelli.bsky.social
2\ What is the paper about?

Own-account work represents a large chunk of the labour market in developing countries, and Brazil is no exception. While some people stress the risks associated with these occupations, others highlight their positive aspects.
tscarelli.bsky.social
About 2/3 of all own-account workers in Brazil appear to have taken this occupation as a result of a financial constraint, as opposed to their first-best economic choice.

This is the key finding of a paper I co-authored with David Margolis, now in EDCC: www.journals.uchicago.edu/doi/10.1086/...

Yeah, I don't think you can ask reviewers to go through the code/replicate results, unless you pay them appropriately. I think a better equilibrium than the status quo would be: people write fewer papers & receive fewer papers to review, are paid to do so, and spend more time on it, including code.

Very happy to see this out! This is a major revision relative to the previous issue. We have included important topics such as minimum wages, migration, and market power. Plus, it now also covers housing informality! Check it out!

What have we learned about the informal sector?

Issue 2 of our #VoxDevLit on Informality by @GUlyssea, Matteo Bobba, @lgadenne.bsky.social & Mariaflavia Harari is out now! ➡️ voxdev.org/voxdevlit/in...

Today's podcast covers the update ➡️ voxdev.org/topic/labour...

Important insight from Stefan Dercon (@gamblingondev.bsky.social): "design interventions that maximise the policy makers’ objective function given their constraints". Economics meets Political Science.
