This looks very cool!! (I had an initial “but what about the policy recommendation” reaction, luckily their “findings do not necessarily support the nativist argument that immigrants… brought disease… the observed relationship stems more from overburdened living conditions”)

Machine Learning is causing massive leaps everywhere. Also in Economic History. There is a conversation we need to have. What ought to be the new scientific standards? Together with two coauthors . Our argument: We should maybe care a bit less about accuracy 📝🧵

Niche PSA: if you are using ggplot2 to make binscatters and using stat="smooth" or stat_smooth to make the regression line, setting ylim and xlim to scale the axes will also censor the data BEFORE estimating the regression coefficients.

We present new annual time-series data on academic human capital across Europe from 1200 to 1793, constructed by aggregating individual-level measures at three geographic scales: cities, present-day countries (as of 2025), and historically informed macro-regions. Individual human capital is derived from a composite index of publication outcomes, based on data from the Repertorium Eruditorum Totius […]

There are several recent papers which could fall under the heading ‘Economic History of the Scientific Revolution’ but this network analysis tracing how scientific ideas diffused amongst scholars in the period 1084-1793 is a real milestone, an ‘epidemiological’ model of how ideas spread like disease

Very happy to share our new working paper: cepr.org/publications...
cepr.org
DP19625 What was in a name? Culture, naming practices and literacy in the past
Given names hide crucial information about cultural attitudes and beliefs that sheds light on how parents raised their children and the importance they attached to education and other values. Relying on the 1860 Population census for the province of Zaragoza (Spain; almost 400,000 observations), this article shows that naming practices, captured by whether children bear more or less common names and/or were named after their parents, help predicting their educational outcomes, even after controlling for a host of individual-, household- and community-level confounders. Crucially, these results differ by sex, birth-order, socio-economic status and the urban-rural divide, which allows identifying the mechanisms in place. In particular, bearing a common name is negatively associated with the likelihood of girls attending school and being literate in rural areas. By contrast, being named after parents had a positive influence on boys' education, a pattern that is especially visible for the eldest son from families who have access to land. In addition, the results reported here are stronger in more complex household arrangements. These results therefore stress the role played by inheritance customs and the continuity of the family line on both naming practices and the way that parents allocated resources between their siblings, as well as highlighting the different expectations around the role that sons and daughters played in these societies.

In the early hours of 2 September 1666, a spark in Thomas Farriner's bakery on Pudding Lane in the City of London ignited a blaze that would go on to consume 90% of the City’s houses. But how did economic activity and wealth rebound after the fire? Philipp Ager of the University of Mannheim and Paul Sharp of the University of Southern Denmark have used contemporary records to describe London’s uneven economic recovery. They tell Tim Phillips about the records they uncovered, and what they reveal about London’s economy before and after the fire.
