    The “sophomore slump” is a widely accepted phenomenon in modern sport culture, commonly conceptualized as a decline in performance during a player’s second year of competition following an outstanding first season. This study empirically verified the absence of sophomore slump through a two-stage network data envelopment analysis and Malmquist productivity index analysis of 616 English Premier League players from the 2014–2015 to 2018–2019 seasons. The relative rankings of individual second-year players were compared with their rankings in the previous season, and second-year and non-...Read more

    A landmark decision (Murphy v.

Even though serious indications suggested that the Professional and Amateur Sports Protection Act (PASPA) was...Read more

    Research examining how information influences pricing, efficiency, and line accuracy in sports betting markets is common.

This indicates the information produced through game play is valuable in improving contest forecasts by both oddsmakers and the market....Read more

    The evolution of competitive balance and its impact on demand is the focus in the field of sports economics. The results of previous studies examining the relationship between competitive balance (CB) and attendance, as well as the direction of the relationship between financial inequality and CB, are not clear. Through panel data of the top five European football leagues, we examine whether there is a causal relationship between the concentration of club wealth and CB. Using different CB measures and the player value concentration as a proxy for wealth concentration, we found that wealth...Read more
