Taylor Swift is in the midst of the European leg of her world tour, with her performances in venues like Wembley Stadium and Anfield touted by some to generate £1 billion for the UK economy.
The tour's popularity is so large that it has been placed on par with the Olympic Games in France and the Euros in Germany as the key events expected to help boost European economies at a time when a recession is close in the rear-view mirror.
However, not everyone is convinced that "Swifonomics" is real.
Looking at her performances in Stockholm over three dates in May, the artist sold around 180,000 tickets, generating some US$81 million for the city.
However, when zooming out and looking at Sweden's overall economy, the concert makes little impact on the country's US$623 billion annual output.
Carl Bergkvist, chief economist at Stockholm's Chamber of Commerce said: “This extra turnover is a great weekend boost for Stockholm and, in particular, its tourism sector.
"But it’s just that — a weekend, with no visible or significant impact on overall economic growth.”
Carsten Brzeski, an economist at ING, echoed similar thoughts, calling the Swift effect "extremely small and temporary, at best".
"There is copious research in the run-up to big events outlining the economic benefits but after the fact you need a magnifying glass to find these so-called benefits in the numbers," he said
