The favorites to win the World Cup
Brazil dominates the competition in Goldman's simulated World Cup, beating Mexico and Croatia 4-1 and Cameroon 5-0 in the group stage. Here are the complete predictions for the groups:First, the model relies heavily on past performance, meaning that it will fail to accurately predict performance for a team that is improving rapidly or that is suddenly confronting a new obstacle, such as an injury. Such dynamism might be rare in soccer. It might be a comparatively boring sport in which the results of matches can usually be predicted based on how well teams have performed in the past.
It is hard to say, though. Goldman did not provide confidence intervals or an R-squared value for their model. These statistics would help readers understand how well the analysts' technique would have worked in past World Cups and how well past performance predicts future results in soccer generally.
Declining a request for an interview, a Goldman representative wrote that the authors of the report preferred to allow their work to speak for itself.
How Spanish football clubs explain the Euro crisis
Whatever the merits of Goldman's model, there is plenty of other worthwhile reading in the report. The section on Spain includes a contribution from D.E. Shaw's Ángel Ubide, who explains in detail how Europe's economy led to a crisis for Spanish football clubs. Ubide writes that many Spanish football managers depend on local banks for credit to recruit new talents, and that these loans are often made without much accountability or oversight.As Spain's financial position deteriorated, this credit evaporated, and many managers found themselves unable to pay their players. In response to the crisis, the national football authority forced clubs to comply with new financial regulations, like so many European banks. The best Spanish players began moving overseas, just as the nation as a whole had to increase its exports, Ubide writes. (That didn't stop two Madrid teams from dominating the Champions League tournament. Real Madrid beat Atlético Madrid in extra time in Saturday's final.)
There is also this graph, which shows that the price level is a good leading indicator for the average number of goals scored in soccer matches. In short, high numbers of World Cup goals have tended to happen in times of higher European inflation:
