The art market’s figures for the first half of 2019 reveal a paradox: sales volumes fell17.4% while the overall price index rose 5%. In other words, the prices of artworksrose while the market contracted. However, the lower sales revenue was notattributable to a fall in the number of transactions, which remained almost perfectlystable; the contraction in turnover therefore essentially reflected the type and qualityof the works offered during the semester.
