Card & Dahl also found that there were other things that explained increases in domestic violence. An increase in temperature and holidays contributed to domestic violence. These were of less interest to the authors as they were more concerned with emotional cues. Another emotional cue examined by Card & Dahl was the important of the game. They found that the more important the game the greater level of domestic violence.
This year the Card & Dahl hypothesis was tested with data from Glasgow. The research was conducted by three people from the University of Strathclyde. Like their US counterparts, Alex Dickson, Colin Jennings and Gary Koop found that significant increases in domestic violence in holiday periods, i.e. around the Christmas and New Year period.
Koop found that Old Firm games (between rivals Celtic and Rangers) increased domestic violence between 28% and 41% depending on the outcome. These games “mattered” to the supporters. Unfortunately, they also “mattered” to their family members.
Dickson, Jennings & Koop end their paper with the hope that Rangers' relegation to the lowest division in Scottish football, for financial irregularities, will allow the authorities time to somehow put in place a plan to deal with future Old Firm games. Agreed.
