报告摘要:Opportunities to study impacts of monitoring technology in the workplace, as opposed to experimental laboratory, are extremely rare. Researchers tend to rely on self-reported survey data sets such as European Working Conditions Survey or Workplace Employment Relations Survey. These surveys only capture self-reported responses by employers and/or employees. Direct field evidence on monitoring, shirking and responses to peer pressures are limited. The famous study by Mas and Moretti (2009) on peer effects on supermarket checkout operators is a notable exception. The sports industry offers excellent opportunities to study impacts of changes in monitoring technology on worker performances due to precise and rich data on worker performances. This paper analyses the impacts on workers (referees and players) from the introduction of Video Assistant Referees (henceforth VAR) as an innovation in monitoring technology designed to improve referee decision-making in football competitions. We find evidence that introduction of VAR has been largely successful in its objectives of using technology to aid worker (referee) decision-making. The percentage of incorrect decisions in games fell and we have evidence that attacking play was encouraged, as measured by shots on and off target. There are fewer offsides and fewer fouls called under VAR which suggests a combination of improved player discipline and better referee performance. We have evidence of a reduction in away team yellow cards in the first season of VAR which can be construed as reduced referee bias. But shirking and referee bias remain as the time taken up by VAR interventions is not fully compensated for by referees in time added on at the end of games. Moreover, the lack of compensation in added time favours home teams that have narrow leads. The lesson is that a change in monitoring technology can improve worker productivity but does not necessarily eliminate agent shirking.
