LENGHT OF STAY FOR TRIATHLON PARTICIPANTS IN THE CHALLENGE MARESME-BARCELONA: A SURVIVAL APPROACH

Sporting events are a very important promotional tool for many cities, given its national and international impact. Many of these cities already have long supported these events as a way to internationally promote their brand. The economic impact of these sporting events not only depends on the number of participants but also, among other factors, on the duration of their stay in the city that hosts the event. The aim of this study, therefore, is to analyze the determinants that determine the length of stay of these athletes in the venue that hosts the event studied, the International Triathlon Challenge Barcelona-Maresme. This event took place on October 3, 2009. More than 2000 participants from 30 countries attended the competition. The model also quantifies the likelihood that an athlete had been in the venue for “t” days (known as hazard function) depending on “t” conditioned to completing the trip.

The method used is a duration model, also known as hazard  or survival model. Thesemodels estimate the length of time spent in a particular state before transitioning to another state. These regression models allow us to estimate when the duration of a state is correlated with the explanatory variables in the observed period. Given that in our model the proportionality assumption holds, the author decides to use a proportional duration model. Among these selected models, the model chosen is the Weibull. The choice of this model is based, first, on the lack of evidence to reject the proportional hypothesis, as seen in the graph of the survival function, and second, from the proportional duration model, the author must choose the better model in order to avoid problems arising from lack of specification. In this case, when the models are nested, the Wald test rejects the null hypothesis of the exponential model. Once the model used is choose, we proceed to perform the data collection. The model uses information extracted from a survey conducted by the Maresme City Council in 2009 to several participants of the International Triathlon Challenge Barcelona-Maresme. The survey was administered to participants during the days prior to the competition and the day of the competition. A total of 346 valid responses were obtained. The model evaluates the destination, spending, type of accommodation used and type of competitors correlated with the duration of the event.

Of all the variables studied, neither age, or the fact that the participants had visited the city hosting the event seem to have a significant effect. Quantitatively, being a foreign participant, expenditure and evaluation of fate, in this order, emerged as aspects that increase the duration of the event analyzed. The dummy variable “foreign participant” seems to capture the fact that participants from another country travel greater distances than the average Spanish participant and having made the decision to travel a far distance des stay lengthens. The results obtained in this study confirm the hypothesis that the participants in sporting events cannot be considered equal in terms of the effects of different factors in their decisions regarding the duration of the event. In summary, the results of the duration model used in this paper shows that the greatest impact of these sporting events is conditioned on the ability to attract foreign athletes.
