Studying the performance and efficiency of countries participating in the Olympic Games is a topic of interest in the area of economics and operations research. Com­monly, efficiency in this area has been analyzed using outputs like number of medals, the number of medals weighted by category, and the number of diplomas, while the most common inputs are gross domestic product (GDP) and population. This paper contributes to the literature by analyzing the countries’ efficiencies in the Rio 2016 Summer Olympics with stochastic frontier models. Moreover, this study aims to fill three research...Read more

After the lockout season in 2004, the 2005 collective bargaining agreement (CBA) introduced salary regulations, as well as revenue sharing, to the teams of the National Hockey League (NHL) with the aim to restore financial competitiveness. Given these objectives, the question arises if efficiencies improved under the new CBA. Using team values as the dependent variable, we performed a stochastic frontier analysis. Our paper suggests that efficiencies immediately improved after the agreement, in particular for low performing teams.Read more
