From conflict minerals to abstract art, and of course Brexit; here is this week in numbers.
The growth in the UK economy by 2020 delivered by Brexit, according to Professor Patrick Minford at Cardiff Business School. This is the most bullish estimate of the Leave vote’s impact on the British economy. Other studies forecast that the UK economy will shrink between now and 2030. The worst case scenarios for that shrinkage are variously estimated at -1% (Open Europe), -3.5% (PwC), -3.9% (Oxford Economics), -7.7% (OECD), -7.8% (National Institute of Economic and Social Research) and, most pessimistic of all, -9.5% (the Treasury, Centre for Economic Performance).
The number of conflict minerals – tin, tantalum, tungsten and gold – that fair trade smartphone organisation Fairphone has managed to source transparently for its supply chain. It has just announced it can source conflict-free tungsten from Rwanda after working with Austrian miner-smelter Wolfram Bergbau and Hütten to re-open the trade in the mineral from that African country. Fairphone now has 100,000 users of its phone and has just released a 2.0 upgrade.
The price paid by an unknown Chinese collector for Damascus Gate, a 50ft abstract expressionist painting by American artist Frank Stella at Art Basel this week. The 1970 painting was one of a series Stella created with a protractor after being inspired by the angles of buildings on a trip to the Middle East. The sale was seen as evidence of a risk-averse mood among art buyers, who have preferred established artists in 2016.
The position at which Rick Astley entered the UK album charts with his new release, 50. It sold 3,700 more physical copies than Tom Odell’s Wrong Crowd. It was Astley’s first chart-topping album since 1988. The feat was especially impressive as a lorry full of copies of his new CD was trashed by migrants en route from the German pressing plant to Calais.
The capacity of a cup that Starbucks fills with latte, according to a lawsuit by two Californian residents. Their suit, the bulk of which has been allowed by a federal judge, alleges that in 2009 the drinks chain created a recipe for smaller lattes to save money. Starbucks says the lawsuit is “without merit”. It has also dismissed a $5m suit, filed in Chicago, that it puts too much ice in its iced lattes as “frivolous”.
The number of body-worn video cameras expected to be used by British police by the end of next year. The issue police will have to face is: what do they do with all that sensitive data? Dare they store it on the cloud?
