Charts vs vibes: FIGHT!
Brexit reduced UK GDP by 6-8%, investments by 12-18% [pdf]
Brexit blamed for a 6–8% UK slump — comments explode into a GDP cage match
TLDR: A research paper says Brexit cut UK economic output by 6–8% and hurt investment, jobs, and productivity. Comments erupted into a brawl over whether GDP matters, with skeptics, long‑term optimists, and tariff watchers trading jabs over data, deregulation, and “was it worth it?”
A new NBER working paper says Brexit shaved 6–8% off UK GDP (that’s the country’s total economic output), slashed investment by 12–18%, and dented jobs and productivity by 3–4%. It’s a research draft, not yet peer‑reviewed, but the numbers were enough to send the comments section into DEFCON drama. One camp shrugged: “Less trade, fewer workers… what did you expect?” Another swung hard: “GDP is meaningless to regular people!” Cue the popcorn.
Then came the clapbacks. A snarky chorus pointed out the contradiction: the same folks calling GDP “elitist” are suddenly wielding it like a sword when it suits their argument. Meanwhile, pro‑Brexit optimists argued the long game: fewer EU rules means faster growth — if Parliament can get its act together. Across the pond, U.S. readers suspected a subtweet of American tariffs, drawing parallels and asking if protectionism always lands with a thud. The vibe? Stats vs vibes, “Project Fear” vs “Project Reality,” and a flood of memes — “Regrexit,” the “This is fine” dog with a Union Jack mug, and spreadsheets on fire. Whether you think GDP matters or not, the thread boiled down to a brutal question: Was it worth it?
Key Points
- •By 2025, Brexit reduced UK GDP by 6%–8%, investment by 12%–18%, employment by 3%–4%, and productivity by 3%–4%.
- •Impacts accumulated gradually over nearly a decade following the 2016 referendum.
- •Analysis combines macroeconomic simulations with micro data from the Decision Maker Panel survey.
- •Negative effects are attributed to elevated uncertainty, reduced demand, diverted management time, and increased misallocation during a protracted process.
- •Contemporary forecasts were accurate over five years but underestimated the decade-long impacts.
