Next up, @Mahreen Kahn @ox.ac.uk on the effects of soft skill training for students in Bangladesh. Skill and employment increase even in the medium term (6-12months), in particular for women. The program was very cost effective at less than 4USD per participant. #OxCSAE2026

Now, @marcjosefwitte.bsky.social @vuamsterdam.bsky.social presents on the direct and indirect impact of a nursing training program for women. The training increases both participants’ and connect individuals’ employment and earning. Spillovers likely emerge due information spillovers. #OxCSAE2026

The next presentation is by Lea Rouanet at the World Bank on whether information on earnings can reduce the gender gap in the impact of TVET training in the Republic of Congo. Short run results show reduced gender gaps but effects dissipate over time as women leave jobs at higher rates. #OxCSAE2026

My first session at #OxCSAE2026 is on female employment. First up is by Nissi Moses @rug.nl on the impact of fast internet on employment rates by gender. She find that access to internet leads aggregate employment to decrease but she observes a narrowing of gender gaps.

🧵A thread on "AI one-shot papers".

This has not been a focus on Bluesky, but on Twitter/X and LinkedIn, there has been a large discussion of the ability to "one-shot" policy evaluation, which David Yanagizawa-Drott has been pursuing in an interesting way: ape.socialcatalystlab.org

Psychology has a whole cottage industry in which people come up with some construct that is essentially "attitudes/beliefs/expectations/feelings about X", and then the central claim is that this construct is a super important determinant of future X outcomes.>

🚨Replication alert🚨
I'm pleased to announce that my replication of Moretti (2021) is now accepted as a comment at AER.

I find ten issues in the paper. My comment focuses on two major problems; in the appendix, I document eight (relatively) minor problems.

Why Underachievers Dominate Secret Police Organizations: Evidence from Autocratic
Argentina

Adam Scharpf
Christian Gläßel

Abstract: Autocrats depend on a capable secret police. Anecdotal evidence, however, often characterizes agents as surprisingly mediocre in skill and intellect. To explain this puzzle, this article focuses on the career incentives underachieving individuals face in the regular security apparatus. Low-performing officials in hierarchical organizations have little chance of being promoted or filling lucrative positions. To salvage their careers, these officials are willing to undertake burdensome secret police work. Using data on all 4,287 officers who served in autocratic Argentina (1975-83), we study biographic differences between secret police agents and the entire recruitment pool. We find that low-achieving officers were stuck within the regime hierarchy, threatened with discharge, and thus more likely to join the secret police for future benefits. The study demonstrates how state bureaucracies breed mundane career concerns that produce willing enforcers and cement violent regimes. This has implications for the understanding of autocratic consolidation and democratic breakdown.

In the second half of the paper, we develop a model with a new mechanism to explain firms’ lack of wage posting. Firms do not include pay information as bargaining offers an insurance mechanism against not being able to hire profitably at the posted pay.

Why? Not because they don’t know which skills firms want. Rather, because job seekers in this context and other contexts have limited information about their own skills (two of my working papers provide evidence on this in Ethiopia and South Africa: docs.iza.org/dp17761.pdf, tinyurl.com/3wsydrv6).

2. Pay information does not increase sorting by skills as high wage salaries do not receive higher-quality applicants. So firms’ worries about under-qualified applicants do not bear out. However, there is also no positive assortative matching of applicants and vacancies.
