Forthcoming in AEJ: Macroeconomics: "The Lost Marie Curies and Foregone Economic Growth" by Jean-Félix Brouillette.

The Lost Marie Curies and Foregone Economic Growth

(Forthcoming Article) - Women made up only 15% of U.S. inventors in 2024. Assuming no intrinsic gender differences in inventive potential, the scarcity of women in research reveals that the U.S. is missing out on some of its brightest minds. How costly is this talent misallocation for aggregate productivity? I develop a model of semi-endogenous growth in which individuals with heterogeneous talent choose between research and production careers. However, several barriers deter women from pursuing their comparative advantage. Lifting those barriers would increase U.S. income per person by 14.1% in the long run, compared with just 1.5% from a 30% R&D subsidy alone.

This recent RCT of an "AI stethoscope" claims the technology "shows promise" for diagnosing cardiovascular conditions. It does not. It is a textbook example of the risks of conducting unprincipled 'per protocol analyses'. Once again, peer review at a major medical journal has failed. 🧵 1/

Graph showing use of AI stethoscope examinations (cardiac waveform recordings for AI interpretation) among recruited GP practices in the intervention group (n=96) during the first 12 months of implementation. Stacked bars represent the number of practices (y-axis, left) stratified by usage intensity category: high users (≥31 uses per month), medium users (10–30 uses per month), low users (<10 uses per month), and non-users (0 uses per month). Darker shades within each bar denote higher usage categories, with high users shown in the darkest shade. The overlaid line graph indicates cumulative number of AI stethoscope examinations (y-axis, right) over 12 months, with numbers above each bar denoting the total number of onboarded practices at that timepoint. AI=artificial intelligence. GP=general practitioner.

Using data from the US & 10 European countries, the OECD LinkEED 2.0 Team analysed the role of firms in the gender wage gap. They find firms account for 10-30% of the gap, mainly reflecting women being more likely to work at firms that pay less to all employees. cepr.org/voxeu/column... #EconSky

The figure shows the gender wage gap (the difference in average log hourly wages between males and females) in log points on the y-axis. The x-axis displays the gender wage premium gap, which is the sum of the sorting and pay-setting components. The diagonal lines represent scenarios in which firm wage premiums account for 10% (top line) and 40% (bottom line) of the total gender wage gap. Early explanations for gender wage gaps focused on human capital or career choices. This column uses data from the US and ten European countries to examine the role of firms. Across all countries considered, firms account for between 10% and 30% of the gender wage gap, mainly reflecting women being more likely to work at firms that pay less to all employees, irrespective of their skills. While men move to higher-paying firms as they advance in their career, women tend to stay behind. Women also tend to sort into low-wage firms in return for more flexibility in working time. The findings suggests that there is a case for complementing family policies with policies focused on firms.

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

It must be very hard to publish null results Publication practices in the social sciences act as a filter that favors statistically significant results over null findings. While the problem of selection on significance (SoS) is well-known in theory, it has been difficult to measure its scope empirically, and it has been challenging to determine how selection varies across contexts. In this article, we use large language models to extract granular and validated data on about 100,000 articles published in over 150 political science journals from 2010 to 2024. We show that fewer than 2% of articles that rely on statistical methods report null-only findings in their abstracts, while over 90% of papers highlight significant results. To put these findings in perspective, we develop and calibrate a simple model of publication bias. Across a range of plausible assumptions, we find that statistically significant results are estimated to be one to two orders of magnitude more likely to enter the published record than null results. Leveraging metadata extracted from individual articles, we show that the pattern of strong SoS holds across subfields, journals, methods, and time periods. However, a few factors such as pre-registration and randomized experiments correlate with greater acceptance of null results. We conclude by discussing implications for the field and the potential of our new dataset for investigating other questions about political science.

‘Novice workers who rely heavily on AI to complete unfamiliar tasks may compromise their own skill acquisition… We find that AI use impairs conceptual understanding, code reading, and debugging abilities, without delivering significant efficiency gains on average.’ arxiv.org/pdf/2601.20245

Abstract Al assistance produces significant productivity gains across professional domains, particularly for novice workers. Yet how this assistance affects the development of skills required to effectively supervise AI remains unclear. Novice workers who rely heavily on AI to complete unfamiliar tasks may compromise their own skill acquisition in the process. We conduct randomized experiments to study how developers gained mastery of a new asynchronous programming library with and without the assistance of Al. We find that AI use impairs conceptual understanding, code reading, and debugging abilities, without delivering significant efficiency gains on average. Participants who fully delegated coding tasks showed some productivity improvements, but at the cost of learning the library. We identify six distinct AI interaction patterns, three of which involve cognitive engagement and preserve learning outcomes even when participants receive AI assistance. Our findings suggest that Al-enhanced productivity is not a shortcut to competence and AI assistance should be carefully adopted into workflows to preserve skill formation - particularly in safety-critical domains.

Great news! IZA (the German labor economics institute that had lost its main source of financial support) has found a new home and will continue as a convener and disseminator of knowledge. Hurrah!

🚨🚨🚨Blockbuster paper out today! Bear with me as I explain why this one is so important. 🤔 The *economic* anger about immigration is based on the false notion that immigrants take jobs or lower wages. A major misunderstanding behind this view is that immigrants only increase the supply of labor.

Auschwitz Memorial@auschwitzmemorial.bsky.social · 2y ago

Auschwitz was at the end of a long process. It did not start from gas chambers. This hatred was gradually developed by humans. From ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder. Auschwitz took time.

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.
