Aggression In Mixed Martial Arts: An Analysis Of The Likelihood Of Winning A Decision, Trevor Collier, Andrew Johnson, John Ruggiero

Within the last decade, mixed martial arts has become one of the most popular sports worldwide. The Ultimate Fighting Championship (UFC) is the largest and most successful organization within the industry. In the USA, however, the sport is not sanctioned in all states because some politicians view the sport as too violent. The sport consists of many fighting forms and, unlike boxing, winning a decision requires judging in multiple facets including wrestling, boxing, kickboxing, and jiu-jitsu. In this study, we estimate the likelihood of winning a decision in the UFC. Using data on individual fights, we estimate the probability of …

Measuring Technical Efficiency In Sports, Trevor Collier, Andrew Johnson, John Ruggiero

Standard economic production theory is the basis for measuring technical efficiency in sports. Using programming or regression models, efficiency is defined as the distance of a given team observation from the technology. In this article, the authors show that the standard measures of efficiency using deterministic models are biased downward due to serial correlation with respect to the efficiency measure. In particular, if the number of observed wins for a given team is affected by the team’s inefficiency, it is necessarily true that another team is able to produce outside of the technology. As a result, the observed frontier is …

Estimation Of Multi-Output Production Functions In Commercial Fisheries, Trevor Collier, Andrew Mamula, John Ruggiero

Measuring the productivity of vessels in a multi-species fishery can be problematic. Typical regression techniques are not capable of handling multiple outputs while Data Envelopment Analysis (DEA) tends to ignore the stochastic nature of production. Applied economists have devoted considerable time to this problem and have developed several methods of dealing with the issue of multiple output technologies in commercial fisheries. Our paper contributes to this literature by providing another method for estimating production functions of vessels operating in multi-species fisheries. We utilize a two-stage model – with data from the West Coast Limited Entry Groundfish Trawl Fishery – using …
