Economic societies from the 18th century were the first type of knowledge sharing societies that focused on useful and practical technical knowledge. We document that they left a lasting fingerprint on the geography of innovation.

Economic societies from the 18th century were the first type of knowledge sharing societies that focused on useful and practical technical knowledge. We document that they left a lasting fingerprint on the geography of innovation.
Additionally, we argue that economic societies created persistent networks of innovations. For this, we apply a gravity-type-model to estimate whether common membership in economic societies was associated with patenting in similar classes in the 19thcentury.

First, we produce evidence for the country of Saxony and its economic society relying on contemporary population census and manufacturing data from the 18th century.

We show that the local presence of society members is a strong predictor for patents and exhibits in the 19th century. We further conduct various measures to mitigate endogeneity, incl. an IV strategy, testing for pre-trends and assigning placebo society seats.

So, did these societies have an actual impact on long-run innovation? In this paper, we have collected and geocoded 3302 members of 15 economic societies in the German lands.

The societies further published their own journals where they collected articles from their members on technical innovations and empirical observations and they announced their own prize competitions.

The members of economic societies were not university employed knowledge elites, but common merchants, bureaucrats, teachers, or landowners. They met in the societies’ headquarters to discuss practical, useful knowledge, that was directly relevant to improving the local economy.

The paper uses this shock to the distribution of scientific fellows across colleges in a difference-in-differences approach. Indeed, we do not observe any pre-trends to the distribution of scientific fellows appointed by the visitors.

During the English Civil War, the University of Oxford supported the king. When the Royalist lost, victorious Parliament was eager to reform the university and cleanse it from Royalist and high church influence.

Next, the paper runs a stacked difference-in-differences approach based on teachers leaving their college. And beyond this, the paper also exploits a new unique historical experiment:

First, it exploits the fact that colleges historically had close ties to regions. E.g. a student from Wales would most likely attend Jesus college. Hence, the paper adopts an IV-strategy where it predicts students’ college and future teachers simply based on their place of origin

This paper introduces new data on the universe of 111,242 students at the universities of Oxford and Cambridge and matches students and teachers to their publications. Using natural language processing, the paper derives a measure of researchers' direction of research.

The course will teach you practical methods in big data and machine learning. How can I use a natural language model for classifying data? What are current trends in the causal econometrics literature?

The paper finds strong empirical evidence of teacher-directed change in the English Scientific Revolution. These results illustrate how teacher-directed change can contribute to paradigm change.

To infer causality, the paper exploits a natural experiment based on the expulsion of fellows following the English Civil War and uses an instrumental variable design that predicts students’ choice of college based on their home regions.
