Labor scarcity and technology adoption in industrialising England: "During the Napoleonic Wars, more than 10 percent of the male population served in the armed forces. Where recruitment was heavy, more machines economizing on labor were adopted." aeaweb.org/articles?id=... #EconSky

Fighting for Growth: Labor Scarcity and Technological Progress during the British Industrial Revolution
(October 2026) - We establish a link between labor scarcity and the adoption of laborsaving technology in industrializing England. During the Napoleonic Wars, more than 10 percent of the male population served in the armed forces. Where recruitment was heavy, more machines economizing on labor were adopted. Naval recruitment, instrumented by warships' coastal access, provides exogenous variation in labor scarcity and suggests that the link between labor shortages and adoption is causal. Where mechanical skills were abundant, the impact of labor scarcity on adoption appears to be larger.

One reason England does so well is our second generation immigrants outperform their peers which is not true in most OECD countries. We are also very good at integration. And it's v sad that this is never acknowledge in debates on immigration.

Love this, by Sen, on theoretical modelling. From "Goals, Commitment, and Identity" #EconSky
The quote says: "The choice of behavioral assumptions in economics tends to pull us in two different—sometimes contrary—directions. The demands of tractability can conflict with those of veracity, and we can have a hard choice between simplicity and relevance. We want a canonical form that is uncomplicated enough to be easily usable in theoretical and empirical analysis. But we also want an assumption structure that is not fundamentally at odds with the real world, nor one that makes simplicity take the form of naivety. There is a genuine conflict here—a conflict that cannot be easily disposed of either by asserting the need for simplification in theorizing or by pointing to the need for realism. What we have to face is the need for discriminating judgment, separating out the complications that can be avoided without much loss and the complexities that must be taken on board for our analysis to be at all useful."

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.

Markets and Mobility: How Employers Structure Economic OpportunityIntergenerational mobility, measuring the ability to achieve economic success regardless of family background, is a critical reflection of a society’s commitment to equality of opportunity. Rising income inequality has raised concerns about the potential erosion of upward mobility. While education has traditionally been viewed as the path to mobility, its transformative power is facing challenges in a rapidly evolving job market. This project reorients the focus of intergenerational mobility research by highlighting the labor market as an arena for the reproduction of advantage. It employs a comparative approach, using administrative data from four countries: Sweden, Austria, England, and the United States. It also incorporates evidence from a broader set of nations through cross-national surveys, longitudinal household surveys, labor force surveys, secondary data, and digital trace data. The project employs cutting-edge empirical methods, including quasi- experimental designs, event studies, within-family comparisons, decomposition analyses, counterfactual simulations, and diagnostic checks to rigorously assess the extent of inequalities in the labor market. The research investigates how family background influences the sorting of individuals to employers and workplaces, accounting for education and occupation, and explores variations in career progression within and between employers. It comprehensively catalogues and assesses mechanisms shaping workplace inequality, contributing to the development of social closure theory. Additionally, the project evaluates intervention strategies, encompassing both employer practices and government actions, to promote fair opportunity in the labor market.
