    No presente estudo, avaliamos o desempenho dos países ganhadores de medalhas nas Olimpíadas de Pequim – 2008. Em vez de expressar o desempenho apenas em termos de medalhas conquistadas, a eficiência relativa dos países será avaliada por meio da utilização da metodologia conhecida como Análise Envoltória de Dados – Data Envelopment Analysis (DEA). Assim, será estimada uma fronteira de eficiência para o conjunto dos países, cotejando os resultados obtidos com os recursos disponíveis em cada país. Os resultados (outputs) serão diferentes combinações das medalhas conquistadas – ouro, prata e bronze – e os recursos (inputs) serão o PIB US$ PPP; a população de cada país; e a esperança de vida ao nascer. We rank the participant nations in the Beijing 2008 Olympic Games according to their technical efficiency. Usually they are ranked in accordance with the number of medals they have won and no resources available are considered. In order to evaluate the relative performance of the countries, we used an output oriented version of Data Envelopment Analysis (DEA). We consider three inputs (GDP, population and life expectancy at birth) and different combinations of three outputs (number of gold, silver and bronze medals won).
