Future-host effect: Australia won 27 medals in 1992, but a full 41 medals four years later - probably due to increased investment in sport in the run-up to the 2000 Sydney Games. The UK, meanwhile, increased its medal haul from 30 to 47 between 2004 and 2008, prior to hosting the 2012 Games. Brazil, however, broke the pattern and did not perform particularly well at the 2012 Games. At this year's Games, we would expect Japan to benefit from the future-host effect.
