AI bubble: "Ten loss making artificial intelligence start-ups have gained close to $1tn in valuation over the past 12 months, an unprecedented increase that adds to fears about an inflating bubble in private markets that could spill over into the wider economy."

We have a new paper in "Intereconomics" on other revenue in the EU budget (a financing source for EU expenditures besides own resources, the main revenue streams). Several new other revenue sources have been implemented, e.g. borrowing related to the COVID-19 Recovery Instrument.

The Draghi Report, One Year Later: Europe Still at the Starting Blocks One year after the Draghi Report, Europe remains trapped in a cycle of low productivity and weak investment

Good article by
@fsaraceno.bsky.social, including the argument that Europe has so far failed to refocus on domestic growth drivers, including public investment as a lever for a revival of private investment: fsaraceno.wordpress.com/2025/10/07/t...
