RESUMO: Understanding the closeness of competition between competitors is of interest for market analysts and antitrust practitioners. It may be summarized by the diversion ratio. We present an empirical method to estimate diversion ratios from market share data using transition matrix estimates. This method can help understand the closeness of competition, going beyond restrictive market-share-based diversion ratios with little data requirements. Two datasets illustrate the method: cross-sectional mobile telecom services in Brazil, and time series of online travel agencies in Russia. The method is also used to calculate counterfactuals and estimate the effect of international online travel agency platforms’ exit from the Russian domestic market in March 2022.. Paper co-authored with Svetlana Golovanova.
