A lot of the debate on AI and science focuses on whether LLMs can generate *new* ideas. Yet 20–80% of existing papers are never cited and presumably not read. By digesting vast uncited literatures, LLMs may meaningfully advance knowledge simply by absorbing *old* ideas.

A tight link between productivity and population density is one of the most robust associations in urban economics. In that light, Scandinavia’s economic transformation before World War I is remarkable, since it occurred in some of Europe’s least densely populated regions.

JOB! I'm hiring a postdoc for 2 years on my ERC MaMo project. Looking for someone with strong quant methods, ongoing work close to the project's aims, and a desire to publish in sociology. Start flexible in the next 12 months. Formal call out shortly, but contact me first.
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.

I really want to stay optimistic about how LLMs can revolutionize social science research. But the fact that I can't get GPT-5.2 to perform a simple word count really makes me wonder about the flurry of papers coming that heavily relies on LLMs for analyzing unstructured data.

New working paper alert: "Financing Innovation: The Role of Patent Examination". @steve-bill-econ.bsky.social, Christopher Coyle and I have been working on this for quite a while now. We are excited to have a full draft for your enjoyment! www.quceh.org.uk/uploads/1/0/...
Financing Innovation: The Role of Patent Examination.

Stephen D. Billington, Christopher L. Colvin and Christopher Coyle.

How does patent examination influence access to finance for innovative firms? We exploit a reform to the UK’s patent system that introduced substantive examination to the patent application process, improving the information available to potential investors on the value of firms’ patents. Using a newly compiled firm-level dataset of exchange-listed corporations, we find that firms holding examined patents were able to borrow more, reflecting improved access to capital markets, and leading to firm growth. Our results highlight the role of patent examination in reducing information asymmetries, enhancing the signalling value of patents, and mitigating financial barriers to innovation.

Why do firms in poor countries not adopt new technologies? One reason: they're too small. We show in a recent paper that the "invention" of the the modern corporate form historically enabled marginal firms to grow and adopt new technologies. Paper forthcoming in the JEH and @voxeu.org column here:
cepr.org
Institutional innovation and the adoption of new technologies
A key barrier to economic development is that while new technologies can offer substantial productivity gains, firms in poorer countries often do not adopt them. This column uses firm-level data to track the adoption of the key technology of the 19th century – the steam engine – during Sweden’s rapid industrial take-off. Much like in many developing countries today, Swedish firms were generally too small to profitably adopt the new technology. The authors document the central role of an institutional innovation – the modern corporation – and demonstrate that when firms were given the opportunity to incorporate, they expanded and adopted steam technology.
