ABSTRACT
This paper investigates how crowds affect the timing of events during football matches. In theory, the presence of fans influences the urgency of the players on the field, and the magnitude of this effect grows during the match. Thus, crowds should lead to a faster increase during the match in goals scored, yellow cards, red cards, and penalty kicks. We test the hypothesis using a data set including pandemic ghost games and we find strong support for the hypothesis as it relates to goals, yellow cards, and penalty kicks but not as it relates to red cards. © The Author(s) 2023.
ABSTRACT
The search for the main factors of the home advantage phenomenon in professional European football is a hot topic for scientific research. We assessed the contribution of individual factors to the home advantage using the statistical results of European city derbies, same-stadium derbies, and matches of the championships of microstates. We compared the statistical results of the European city and stadium derbies, as well as matches of the championships of Luxembourg and Malta, played in the presence of spectators in the stands (2017–2020) and without spectators in the Covid-19 pandemic (2020–2021). The number of home victories was compared with the number of away victories using a paired t-test, and the impact of the number of spectators in the stands on the outcome of matches was assessed based on a logistic regression model. Home advantage was present in European city derbies and Luxembourg championship matches before the Covid-19 pandemic. For popular city derbies from Europe's elite leagues, home advantage has been maintained through the Covid-19 pandemic with no spectators in the stands. There was no home advantage in stadium derbies and Maltese championship matches. We conclude that the home advantage can be determined by the influence of only one factor – familiarity of the players of the home team with the football stadium. The information presented in the article can be used by players, coaches and managers of professional football clubs to improve the performance of the game. © Siberian Federal University.

ABSTRACT
Home advantage is an accepted phenomenon in contemporary European football. The home team is more efficient and wins more games. Nonetheless, the factors contributing are still debated. Prominent factors for the home advantage are the presence of supporters and their influence on players, referees bias, travel of the away team to the venue of the match, hormonal effects or territoriality protection, familiarity with the venue of the match, special tactics of playing at home and away. During the global pandemic COVID‑19, most major European football championships had to be played without supporters. This provided a unique opportunity for researchers to explore the contribution of the above factors to home advantage. This article presents an analysis of recent literature data aimed at investigating the factors contributing to home advantage in European professional football. The study found that all of the above factors can influence home advantage. However, it has not yet been possible to determine the main dominant factor of home advantage. Home advantage is a multifactorial phenomenon and exact causal relationships remain to be determined. The strength of the factors varies depending on the development level of football and the geographical size of the country, the skill of the players and teams in the professional league. The information presented in the review can be used by coaches, managers and sports leaders to develop a modern game strategy, taking into account home advantage factors. © Siberian Federal University.

ABSTRACT
Social pressure may have relevant consequences in many contexts but it is hard to evaluate it empirically. In this paper we exploit a natural experiment in soccer to provide clear evidence of its effects. We aim to study how social pressure from the crowd in a stadium affects both players and referees. While in normal matches crowd support may be correlated to a host of variables affecting the outcome of interest, we exploit the fact that after the health emergency for the Covid-19 pandemic in 2020, soccer matches in top European Leagues have been allowed only behind closed doors, that is, without spectators in the stadiums. We use data of first and second division of five major European Leagues (Germany, Spain, England, Italy and Portugal) for the last 10 seasons and compare - using a differences-in-differences analysis - several outcomes (determined by players' performance and referees' decisions) of matches played with crowd support to the same outcomes when matches were played without crowd. We find considerable effects of the pressure from the crowd: while with the support of the crowd a considerable home advantage emerges in various measures of performance (points, goals, shots, etc.), this advantage is almost halved when matches are played behind closed doors. Similar effects are found for the behavior of referees: decisions of fouls, yellow cards, red cards and penalties that tend to favor home teams in normal matches, are much more balanced without the crowd pressing on referees. The evidence we provide strongly supports the idea that social pressure has intense effects on agents' behavior. (PsycInfo Database Record (c) 2023 APA, all rights reserved)
ABSTRACT
This paper examines the effect of spectators on women's football games. COVID-19 and related restrictions provide a unique opportunity with an adequate sample size to test the effect of lockdown on sports activities. Studies have recently exploited this opportunity for men's football to better understand the potential causes of home advantage and, more specifically, assess the psychological consequences when matches are played without supporters. Despite the increased scientific interest, there was only one paper that focused on women's football. Therefore, we aim to contribute to this research field by considering matches from four major European women's football leagues. The findings suggest that for three of these leagues, lockdown has a statistically significant effect on the sanctioned yellow cards by either reducing the number of yellow cards sanctioned to the away teams or increasing the number of yellow cards sanctioned to the home teams. Nonetheless, lockdown does not affect any final match outcomes;therefore, it does not significantly affect the magnitude of home advantage for women's games. © 2023
ABSTRACT
The introduction of the video assistant referee (VAR) was a landmark in soccer history, yet it is not empirically examined whether the technology contributes to the most supreme value of the game: fair play. Because referees are said to be one driving cause of the home advantage (HA), the aim of this study was to examine whether the HA changed in the German Bundesliga since the implementation of the VAR in the season 2017/18. We examined a total of 2448 games during the four seasons before and after the implementation of the VAR with regards to the game outcomes (i.e., goals and points) as well as indicators of referee bias (i.e., fouls, yellow cards, 2nd yellow cards, red cards, and penalty kicks) for both the home and the away teams. Findings indicate that the VAR influences game outcomes to a fairer degree. Specifically, (i) we found statistical evidence for the HA before, but not after the implementation of the VAR. However, (ii) these results need to be interpreted with caution because direct assessments of the change induced by the introduction of the VAR are not statistically significant. Finally, (iii) with the implementation of the VAR, fewer fouls were committed by both the home and the away team.

ABSTRACT
The aim of this study was to understand how training and playing conditions during the COVID-19 pandemic affected the performance of Euroleague Basketball players. Using a non-participant observation analysis, the study compared the seasons before the lockdown (2018-2019 and 2019-2020; pre-pandemic) with the season after restart (2020-2021; pandemic). Paired t-tests and Wilcoxon tests were applied for variables with normal and non-normal distributions, respectively. The results revealed significant changes (p < 0.05) in several offensive and defensive performance-related variables during pandemic times (without attendance): free throw attempts, free throw percentage, turnovers, three-point attempt rate, fouls (small effect sizes, ESs), points, and possessions (trivial ES). The pre-pandemic HA (70%) significantly decreased after the lockdown, with games played with no crowd (â¼51%; p = 0.018, large ES). The one-sample t-test showed that the HA after the COVID-19 interruption was not significantly greater than 50%, indicating that the HA did not endure during the pandemic condition. Although significant differences between home and away teams were found for most performance-related variables (excepting turnovers) in both pre-pandemic and pandemic conditions, variations of the relative HA were only significant for free throw attempts (large ES), points (medium ES), and turnovers (medium ES). The results of this study showed that performance variables were affected by the COVID-19 lockdown. Thus, these findings may help coaches, players, and referees to counteract unwanted competitive events and improve their overall performance, regardless of the contextual/situational circumstances encountered.
ABSTRACT
The current study focuses on sport fans' attitudes toward the presence of the first transgender soccer referee in an elite league in Israel, and largely reflects the broader discourse on gender diversity and inclusion in general. Soccer referee Sapir Berman's announcement of her gender transition may have been exceptional, but it joins the broad debate on the role of transgender individuals in sport. Research findings indicate that fans expressed ambivalent reactions to the announcement. Although many responses reflected impressive open-mindedness and support for the referee and her decision, a wide range of opposition strategies was also identified, including disgust, ridicule, violence, and concerns of an existential threat caused by changes in the traditional gender order. The fact that the announcement was made during the COVID-19 pandemic also affected the nature and the contents of fans' responses.
ABSTRACT
Most studies of the effect of COVID-19 restrictions on home advantage have been conducted on men’s soccer, with the women’s game lacking scientific attention. The present study fills this gap by investigating games in Swedish Damallsvenskan women’s soccer league. Comparing games in the 2019 and 2020 seasons, we find a slight, but not statistically significant reduction in home advantage in games without crowds in terms of goals scored and points achieved. However, unlike in most studies on men’s soccer, we find that away teams received significantly more yellow cards in games without crowds compared to games with crowds. We discuss our results in the context of the findings in men’s soccer. JEL Classification: D00, J71, L00, Z13, Z20. © 2022 SAGE Publications.
ABSTRACT
The aim of this study was to evaluate the effects of the COVID-19 (absence of spectators) on the results of football teams in 5 popular leagues in the world (English Premier League, Italian Serie A, Spanish LaLiga, German Bundesliga and French Ligue 1). This research was descriptive-comparative. Therefore, the results of football teams were analyzed from the 2015/16 season to the middle of the 2019/20 season (before COVID) and the continuation of the 2019/20 season to the 2020/21 season (after COVID). The number of matches analyzed was 10,853, including 2,546 after COVID matches. The variables that were analyzed were: home Advantage, ratio of goals scored (HGSR) and ratio of goals conceded (HGCR) in home games. The results of t-test showed a significant decrease in home advantage (p=0.044) only in the German Bundesliga. In addition, in the EPL, none of the variables showed a significant difference. In the Italian, German and French leagues, HGCR increased significantly after COVID pandemic (p<0.04). In the Spanish league, HGSR showed a significant decrease (p<0.04). In this study, only the absence of spectators over home advantage was examined. Although spectators may influence the results, teams still perform better at home in the COVID pandemic duration. So, we can conclude the location of the events can be important. Also, the referees can be unfairly biased in favor of one side or another by the presence of crowds. Hence, future research may examine other factors.
ABSTRACT
The COVID-19 pandemic provides a natural experimental framework to comprehensively test the effect of crowds on both referees and players. We examine this from a North American perspective, using data from three major leagues: the National Basketball Association (NBA), National Football League (NFL) and National Hockey League (NHL). In all three leagues in the 2020–2021 season, matches were played either in empty stadiums or before diverse audience sizes. We find that the lockdown affects NBA and NFL results, by lowering the prospects of winning and the expected scoring points of the home team, when games are played without an audience. Conversely, the lockdown does not substantially influence the outcomes of NHL games. We also examine the effect of audience size on game outcomes using historical observations from the past decade, when no lockdown measures were in force. Interestingly, a larger audience size increases the chance of winning and the expected scoring points of the visiting team for NFL games. No significant effect of the audience size on match outcomes is observed for NBA or NHL games. Regarding referee decisions, spectators do not significantly influence referee calls of NHL matches. As for NBA and NFL, the lockdown significantly increases the total number of referee calls but does not prompt more biased decisions towards either of the teams. Finally, a larger audience leads to referee calls more favourable to the visiting team for NFL games. These results extend the literature regarding crowd pressure on the behaviour of players and officials, with an indication that the specific sports activity has a pivotal role in the response to a cheering audience.
ABSTRACT
The present study examines a specific type of referee biases, home bias, and analyzes how the presence of fans affects home bias by using NBA games played in empty arenas during the COVID-19 pandemic in the 2020-2021 season and matches played before the pandemic from 2017 to 2020. This research also uses a unique data set from NBA Last Two Minute Reports to assess referees' performance at the play level. The findings show crowd support does not cause referees to treat home and away teams differently in crucial situations during the NBA regular season, contrary to the results in most prior studies.
ABSTRACT
We use a series of historical natural experiments in association football to test whether social pressure from a home stadium crowd affected behavior and outcomes. The standout effect of an empty stadium was that referees cautioned visiting players less often, by over a third of a yellow card per match or once for every 22 fouls committed. Stadium crowds caused referees to favor the home team in their decision-making. Empty stadiums appear to have reduced the overall home advantage in the final outcomes of football matches, but we cannot statistically reject no effect.
ABSTRACT
The main factors for home advantage (HA), quantified by the number of points won at home expressed as a percentage of all points, are believed to be crowd support, territoriality, familiarity, and travel fatigue. In 2020, the German Soccer Bundesliga interrupted its championship due to the Covid-19 pandemic after 25 rounds and the last nine rounds were played without audience. This unique situation allowed studying the effect of spectators on the team's performance and the referee's decisions. We hypothesized a decrease in HA and a more balanced distribution of fouls and disciplinary cards in the games without audience (GWOA) compared to the games with audience (GWA). We evaluated n = 223 GWA and n = 83 GWOA of the season 2019/20 and all games of the preceding season 2018/19 to analyze the distribution of game outcomes (wins, losses, and draws) and HA. We analyzed the number of fouls, disciplinary cards, and penalty kicks. We found significant differences in HA between GWA (HA = 54.35%) and GWOA (HA = 44.1%) as well as GWOA and games of 2018/19 (HA = 57.63%). The distribution of game outcomes in GWOA did not differ from GWA but differed significantly from 2018/19 (p = 0.031). The distribution of fouls showed a significant difference to equal distribution in GWA [home: 2,595 (48.56%); away: 2,749 (51.44%)] but not in GWOA [home: 1,067 (50.54%); away: 1,044 (49.46%)]. In the GWOA, we counted 178 (51.1%, home) and 170 (48.9%, away) cards, representing a significant difference in the distribution to GWA [home: 405 (44.85%); away: 498 (55.15%)]. The number of red cards differed significantly from an equal distribution for GWA (14 home and 28 away) but not for GWOA (eight home and seven away). In the last nine rounds without audience, we observed more home losses (36) than home wins (27). Hence, the Covid-19 lock-down led to a home disadvantage. One reason for this surprising result could be that the home team is missing an important familiar aspect when playing in their empty stadium without social support from their home audience. Furthermore, both teams know about the HA thus the away team could be more motivated in this unusual situation.
ABSTRACT
The home advantage and unconscious referee bias are two well-documented phenomena in professional sports, especially in association football. Among the various factors determining them, the crowd noise is considered as one of the most relevant; yet, the majority of previous studies could not isolate its contribution. The possibility to study the effects of crowd noise - or, better, of its absence - in an ecological context was given by the matches played behind closed doors due to the COVID-19 pandemic. The aim of the present study was to investigate whether home advantage and referee bias still occur (and to what extent) during matches played in absence of spectators. In particular, the focus was on the first and second divisions of the top four countries in the UEFA ranking, for a total of 841 matches behind closed doors. The hypothesis was that, if these phenomena are largely due to the effect of crowd noise, the absence of spectators should reduce their occurrence. Various parameters for each of the two phenomena were considered, and the analyses revealed a reduction of home advantage and the absence of referee bias. The results bring further support to the claim that, among all the factors contributing to home advantage and referee bias, crowd noise has a relevant role. Thus, spectators can significantly contribute to determine the dynamics and the outcomes of professional football matches.
