This paper by the late, great Nick Crafts, on competition and productivity in the UK, well worth a read: cepr.org/voxeu/column...

Competition cured the “British Disease”
Britain’s relative economic decline throughout the 20th century – the so-called “British disease” – was a national embarrassment that only went away in the 1980s. This column presents new research showing that competition provided the cure. Only when Britain returned to a regime of competition and openness similar to that which had prevailed before World War I did productivity growth resume.

Great piece on model collapse - the output passed the LGTM test (looks good to me) but has errors. This output then trains further LLMs and then weakens LLMs and ultimately the model collapses (garbage in, garbage out) open.substack.com/pub/garymarc...

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.
