New Zealand second best performer at Olympics
With a haul of 13 medals, New Zealand has outperformed the best predictions of the world’s number crunchers by a massive
162.5 per cent, according to a Massey University economics lecturer.
Dr Michael Naylor, from the School of Economics and Finance, has compiled a table of Olympic medal performance by
combining the predictions of the four leading mathematical models used for this purpose. Between them the models include
factors like population, per capita income, and financial support for athletes.
“In the least week New Zealanders have been intensely interested in New Zealand’s relative Olympic medal performance,
especially how we have done comparatively to other countries,” says Dr Naylor. “My calculations show that New Zealand
outperformed what we could relatively expect to achieve by over 160 per cent, and we were second best in the world.”
Only Iran, with 12 medals, exceeded expectations by an even greater degree. However, New Zealand beat the performance of
countries like Jamaica, Great Britain, China, and the United States. Our trans-Tasman neighbours, after a disappointing
Olympics campaign, ranked just 26th.
Dr Naylor says he averaged the predictions of the most accurate models used to predict Olympic medals to formulate his
table.
“The models of Andrew Bernard from Dartmouth’s Tuck School of Business and Daniel Johnson of Colorado College have
proved to be uncannily accurate – above 95 per cent,” he explains. “The Bernard model uses an equal weighting of
population and GDP, then adds in a host country effect and the country’s performance in previous Olympic Games.
“The Johnson Model uses those factors proportionally weighted, as well as neighbouring country and country specific
factors. Factors like climate and being communist have been shown to now be insignificant.”
To the Bernard and Johnson models, Dr Naylor also added the more recent studies by Goldman Sachs and
PricewaterhouseCoppers, which used a wide range of metrics. His results appear in the table below.
