It's been interesting and puzzling to witness the problems with accuracy in UK economic statistics over the past few years. (See the links in the next tweet for more.) It seems that the Office for National Statistics, ONS, now struggles to effectively measure basic figures such as employment, trade, and inflation. This resulted in a quite scathing government report published last summer, where Robert Devereux, a former permanent secretary, concluded that "most of the well-publicised problems with core economic statistics are the consequence of ONS’s own performance." There's a lot of discussion about the travails facing the UK these days (including this big piece in The Atlantic a few weeks ago[1]), and the problems with the ONS feel like an unsettling microcosm of diffuse decline in broader institutional competence. Anyhow: at Stripe, we became curious about the UK's published entrepreneurship data. While we observe a boom in many parts of the world, official figures don't show a similar increase in the UK. In the latest Stripe Economics post, we dug into the data, and, as far as we can tell, the official figures are probably misleading. The good and the bad news (mostly good, I think!) is that the UK is almost certainly witnessing an unmeasured boom in entrepreneurship: UK-specific issues aside, I suspect that this measurement question is illustrative of forthcoming econometric challenges. Keeping the world's macro indicators up-to-date in response to the faster-than-usual changes wrought by AI will be both increasingly difficult and increasingly important in the coming years. [1]
