TOURNAMENTS AND OFFICE POLITICS: Evidence from a real effort experiment

In many environments, tournaments can elicit more effort from workers, except perhaps when workers can sabotage each other. Because it is hard to separate effort, ability and output in many real workplace settings, the empirical evidence on the incentive effect of tournaments is thin. There is even less evidence on the impact of sabotage because real world acts of sabotage are often subtle manifestations of subjective peer evaluation or “offce politics.” We discuss a real effort experiment in which effort, quality adjusted output and o?ce politics are compared under piece rates and tournaments. Our results suggest that tournaments increase e?ort only in the absence of offce politics. Competitors are more likely to sabotage each other in tournaments and, as a result, workers actually provide less e?ort simply because they expect to be the victims of sabotage. Adjusting output for quality with the rating of an independent auditor shrinks the incentive effect of the tournament even further since output tends to become more slipshod. "The person who says ‘I’m not political’ is in great danger... Only the fittest will survive, and the fittest will be the ones who understand their offce’s politics." Jean Hollands, quoted in Playing Offce Politics, Newsweek, 16 September 1985

Incentives versus Sorting in Tournaments: Evidence from a Field Experiment

A vast body of empirical studies lends support to the incentive effects of rank-order tournaments. Evidence comes from experiments in laboratories and non-experimental studies exploiting sports or firm data. Selection of competitors across tournaments may bias these non-experimental studies, whereas short task duration or lack of distracters may limit the external validity of results obtained in lab experiments or from sports data. To address these concerns we conducted a field experiment where students selected themselves into tournaments with different prizes. Within each tournament the best performing student on the final exam of a standard introductory microeconomics course could win a substantial financial reward. A standard non-experimental analysis exploiting across tournament variation in reward size and competitiveness confirms earlier findings. We find however no evidence for effects of tournament participation on study effort and exam results when we exploit our experimental design, indicating that the non-experimental results are completely due to sorting. Treatment only affects attendance of the first workgroup meeting following the announcement of treatment status, suggesting a difference between short-run and long-run decision making.tournaments, incentives, sorting, field experiments

The Dispersion of Employees' Wage Increases and Firm Performance

In this contribution we examine the interrelation between intra-firm wage increases and firm performance. Previous studies have focused on the dispersion of wages in order to examine for the empirical dominance of positive monetary incentive effects compared to adverse effects due to fairness considerations. We argue that the dispersion of wage increases rather than wage levels is a crucial measure for monetary incentives in firms. The larger the dispersion of wage increases the higher the amount of monetary incentives in firms. In contrast, huge wage inequality without any promotion possibilities does not induce any monetary incentives. Evidence from unique Danish linked employer employee data shows that large dispersion of wage growth within firms is generally connected with low firm performance. The results are mainly driven by white collar rather than blue collar workers.Fairness, Firm performance, Inequality, Monetary Incentives, Wage increases, Wage Dispersion

Small World Network of Athletes: Graph Representation of the World Professional Tennis Player

The paper proposes an alternative way to observe and extract the multiple matches games of sports, i.e.: tennis tournament in the Athlete’s Historical Relative Performance Index and its representation as graph. The finding of the small world topology is elaborated along with further statistical patterns in the fashion of the weighted and directed network. The explanation of the sport tournament system as a highly optimized system is hypothetically proposed. Finally, some elaborations regarding to further directions of the usability of the proposed methodology is discussed

THE Economics of Match-Fixing

The phenomenon of match-fixing does constitute a constant element of sport contests. This paper presents a simple formal model in order to explain it. The intuition behind is that an asymmetry in the evaluation of the stake is the key factor leading to match-fixing. In sum, this paper considers a partial equilibrium model of contest where two asymmetric, rational and risk-neutral opponents evaluate differently a contested stake. Differently from common contest models, agents have the option of choosing a second instrument to affect the outcome of the contest. The second instrument is assumed to capture positive investments in ‘contest management’ – namely efforts paving the way for a match-fixing. In particular, it will be demonstrated that, under some conditions, an asymmetry in the evaluation of the stake can lead to a concession from one agent to the other and then to a match-fixing. Eventually the intuitions and results of the model will be applied to make a comparison between the FIFA World Cup and the UEFA Champions League tournaments.Contest; Football; Sport Contest; Contest Management; Match-Fixing; Asymmetry in evaluation; Concession; FIFA; UEFA; CHampions League; World Cup
