This study explores the sustainability of work groups in the industry by enhancing team commitment via person-group fit and its boundary conditions. Specifically, we examine the relationship between person-group (PG fit) and team commitment, introducing person-organization (PO) fit and person-supervisor (PS) fit as moderators. Using data collected from a Korean company, this study reports that a three-way interaction between PG fit, PS fit, and PO fit predicts an employee’s commitment to their team. The results highlight that PS fit can compensate for PG fit when the level of PG fit is low by stimulating team members to commit to the work team. Likewise, PG fit also plays a compensatory role for inducing team commitment when confronting poor PS fit. The results reveal that as long as PG fit is high, PO fit is more important than PS fit in enhancing team commitment. However, when PG fit is low, high PS fit with low PO fit produces a higher level of commitment to the team than low PS fit with high PO fit.

This study seeks to find factors that determine the mobilization of spectators in games of the Korean professional baseball league for sustainable development. In particular, it re-examines the uncertainty-of-outcome hypothesis by looking at the effect of competitive balance (CB) on seat occupancy in stadiums. Data for 2160 games over three years (2015–2017) from the archives of the Korea Baseball Organization (KBO) were analyzed. The results show that the CB of the home team, with the entire teams, affects seat occupancy rate (SOR). It is also shown that there exists an inverted U-shaped curvilinear relationship between CB and SOR. However, the winning percentage of the home team in the entire league had a significant impact on the SOR. This implies that the overall athletic performance of the home team in the league competing with all other teams is much more important than the home team’s competitive balance in the season played before the game, for attracting fans to the stadium.
