This study is focusing on trying to find patterns and tendencies in previous Olympic Winter Games forthe economic variables regional GDP, rate of unemployment and tourism, which are then applied toStockholm County. By doing this, the study is trying to predict changes in these variables in the caseof a future Winter Olympics in Stockholm, Sweden. The method used is based around linearregressions. By applying linear regressions on changes in these variables from previous WinterOlympics, the study tries to find similar patterns both in the period leading up to the event, as well asa period following the event. The results are found to be very individual from event to event whichimplies that there is no general effect from hosting the Winter Olympics that can be expected.However, some trends, regarding specific events that are more likely to resemble a potential WinterOlympics in Sweden, shows us that an increase in regional GDP and a decrease in regional rate ofunemployment might be the effects of a swedish event.
