    Reconsidering performance at the summer Olympics and revenled comparative advantage
    (2022) Tcha, Moonjoong; Pershin, Vitaly
    This paper examines the performance of the participating countries at the Summer Olympic games. It investigates each country's performance and attempts to identify the determinants of this performance in each sport, and also examines other issues related to specialization at these games using the concept of revealed comparative advantage (RCA) developed in the field of international economics. Each country's RCA is explained by geographical biological as well as economic variables of the participating countries. Most previous studies investigated the correlation between total/per capita performance and a wide range of variables, using a range of methods that we consider to be inappropriate. A few studies employed more appropriate censoring methods, however they did not consider heterpscedasticity or non-nomality in their regressions that could make the estimates inconsistent. In addition, RCA and specialization in the Olympic games has never been analyzed. Our analyses present the determinants of each country's specialization in sports and the patterns of RCA, which are substantially different from those obtained when analyzing total and per capita performance. We also found that high-income countries specialize less in other words, they win medals in a more diversified range of sports, which is analogous to a country's patterns of specialization in production a topic frequently explored in international economics.
