Research on sustainability and/in sport and, specifically, on the ecological aspects of participatory sporting events is still very scarce despite the recognition these topics have received by actors like, for instance, the European Commission and the United Nations. Against this backdrop, this paper sheds light on a field that is virtually uncharted in academic research, which is the environmental attitudes and willingness to pay for environmental sustainability of participants in participatory sporting events in Europe. In collaboration with the organizer of the Frankfurt Marathon, a study was conducted with a specific focus on German (speaking) marathon runners. In total 1764 data sets were collected with a German (1455 respondents) and an English (309 respondents) online questionnaire. Very insightful descriptive analyses showed that the awareness for the issue of sustainability and sport is still low and that ecological initiatives only have a medium influence on the evaluation of a marathon event. Nevertheless, particularly the German-speaking respondents indicated a high willingness to pay for environmental sustainability in general and for specific measures that can enhance the environmental friendliness of a marathon event, in particular. As will be discussed in the paper, these insights have important managerial implications and are a valuable basis for further research in this evolving field.

This study perceives professional European football as one of the most relevant event-related entrepreneurial ecosystems (EEs) worldwide. It also identifies a healthy sporting competition in the five most popular European football leagues (Spain, England, Germany, Italy, and France), the “big five,” as a key pillar for the functioning of this ecosystem. By applying a quantitative approach, competitive intensity (CI) is measured for all big five leagues for 21 seasons (1998/99 to 2018/19). The chosen method does not only convey an overall indication of the competitive health of the entire league but also provides detailed information on the four important sub-competitions (championship race, qualification for Champions League or Europa League, and the fight against relegation). In all five leagues, seasonal CI tends to decrease over time, and especially over the last decade. The main reason is a decline in the intensity of the championship race while all other sub-competitions show relatively robust CI values. Overall, it can be concluded that the competitive health of the big five is intact, but the dwindling CI of the championship races can harm the EE of professional European football in the long run. Accordingly, it should be closely monitored in the future.

Purpose: For managers of sports leagues, it is crucial to produce an attractive competition. For that to happen, it is vital to consider that leagues frequently have more sub-competitions than “just” the championship. In European top football leagues, for instance, four sub-competitions are common (championship, qualification for Champions- or Europa League, avoiding relegation). This paper introduces a new method for measuring competitive intensity (CI) in round-robin sports leagues considering all relevant sub-competitions and applies it to Germany's Bundesliga.Design/methodology/approach: The newly developed model calculates a CI-Index for each sub-competition and the league as a whole. The application to the Bundesliga analyzes its viability and the development of the league's CI over the past 22 seasons.Findings: The newly introduced CI-Indices prove to be a viable tool for evaluating a league's competitive intensity. The application to the Bundesliga shows that the seasonal CI dropped after 2009/10, which can mainly be attributed to a decline in the championship's CI.Practical implications: The results show that it is important to facilitate a high CI in each of Bundesliga's four sub-competitions. Efforts have to be made to ensure that especially the Europa League remains as attractive as possible for the participating teams and their fans because this sub-competition constantly makes the greatest contribution to the seasonal CI.Originality/value: The new method measures competitive intensity by quantifying the different sub-competitions and their contribution to the seasonal CI. This allows the organizers of sports leagues to assess the intensity of the individual sub-competitions as well as the league as a whole.

Purpose: The Premier League (PL) and the Bundesliga (BL) were chosen for this study due to their fundamentally different approaches to ownership regulation and the distribution of media revenues. Regulation in the PL is very liberal if compared to the BL's 50+1-rule. In the BL, the distribution of media revenues is mainly based on past performance, whereas equal distribution is dominant in the PL. The specific aim of this paper was a longitudinal analysis with a focus on the final outcome of the seasons.Design/methodology/approach: This study looks at competitive intensity (CI) in the men's BL and the English PL because it is a crucial indicator for the long-term success of a sports league and the participants. To calculate the CI of both leagues and of all relevant sub-competitions (championship, Champions League (CL), Europa League (EL), Conference League (CoL) and fight against relegation), a CI index (CII) model was generalised and applied for an examination period spanning from 1998/99 to 2020/21.Findings: Until 2008/09, seasonal CI in the BL was somewhat higher than in the PL. But afterwards, the BL's championship race's CI dropped considerably, while the PL's CI for qualification for the CL rose profoundly. Results also showed that the introduction of the CoL raised the leagues' CI indices.Originality/value: Besides a methodological contribution with the generalisation of the applied CI index model, the findings are discussed in the context of the above-mentioned regulatory and distribution mechanisms also taking into account the very current discussion regarding general regulatory changes within European football.
