The not-so-free agent: Non-performance factors that contribute to free agent compensation premiums

In this study, the authors examine Major League Baseball free agency to identify whether certain factors beyond a player’s on-field performance contribute to contract premiums. These premiums are considered to be the difference between the compensation a player receives in free agency and the marginal revenue product (MRP_t-1) in their contract year. Using 345 free agent transactions over a four-year period (2012–2015), the authors examine the relationships between potential free agent contract premiums and the attributes of a player’s previous team, as well as how contract premiums may be influenced by the level of interest from other teams and certain facets of the acquiring teams. Results suggest that free agents tend to receive compensation premiums when they played for a successful team during their contract year. Playing for a large-market team during their contract year also influenced contract premiums. In addition, free agents tended to realize compensations premiums when multiple teams were bidding for their services, the acquiring teams were in playoff contention the prior year, and the acquiring teams possessed relatively more financial resources. Findings shed additional light on how factors peripheral to a player’s on-field performance may influence the free agency market. Recommendations include that effective control mechanisms are necessary to ensure free agent compensation is commensurate with the value of the player.

“三个课堂”常态化按需应用:挑战与出路

“三个课堂”作为扎根于中国本土的教育信息化创新实践,肩负着提升教育质量、促进教育公平、推动教育创新的历史使命。在推进“三个课堂”常态化按需应用的过程中,质量忧思、公平焦虑和创新风险是其必须直面的三大挑战。该文提出:在质量提升上,要持续改进临场感和交互性以解决边际效用递减的问题;在促进公平上,要有整体思维以规避数字鸿沟和数字难民的产生;在应用创新上,要避免买得多用得少和百分之百全覆盖这两个极端,以及由此导致的有变化而无改革和有变化而无改良,并以复杂系统的方法论应对创新中的风险。
