Work 21 minutes in Sweden

To be able to buy a BigMac you need to work 21 minutes in Sweden.

As everything else it's goes much faster in Tokyo, you need to put in 10 minutes work there to buy the BigMac.

Here are some other times reported by the UBS bank study.

Tokyo 10 minutes
New York 13
Sydney 14
Toronto 14
London 16
Berlin 17
Copenhagen 18
Oslo 18
Helsinki 19
Paris 21
Stockholm 21
Beijing 44
Bogota 97

Scandinavian countries have a similar profile, Copenhagen 18, Oslo 18, Helsinki 19

Other findings according to the UBS study show that Oslo is the worlds most expensive city to live in closely followed by London, Copenhagen, Tokyo, New York, Stockholm and Helsinki in a approximate order.

I would agree with the study, at least as far as the fact that it's very expensive to stay in Oslo. Stockholm is a bit cheaper but since the wages are lower than in Oslo it might end up being about the same cost of living.
