State of the art: Chinese market flounders

This episode of The Intelligence from The Economist covers three distinct topics: the slump in China's art market due to the country's property crisis, COVID lockdowns, and governmental distaste for opulent spending; an analysis of British emigration statistics, revealing that claims of a "brain drain" are likely overstated due to changes in data collection methods; and an obituary for the American penny, which has been discontinued after 230 years due to its low value and high production cost.
