This study uses a two-stage DEA model to evaluate the efficiency of countries that participated in the Rio 2016 Olympic Games. In the first stage, the authors calculated the efficiency scores using the number of athletes as the input, and the numbers of gold, silver, and bronze medals earned by each country as the outputs. In the second stage, they analyzed the effects of economic, demographic, and political factors on the efficiency scores. They show that GDP and low levels of democracy are also positively associated with efficiency scores, especially in the less efficient countries.
