 in 2019, CEPR criticized the Organization of American States (OAS)'s audit of the 2019 Bolivian general election, which concluded that the results of the elections should be voided because there were "drastic and hard-to-explain change in the trend of the preliminary results after the closing of the polls".Co-Director Mark Weisbrot contended that the report "provides absolutely no evidence — no statistics, numbers, or facts of any kind — to support this idea", and called on the OAS to retract its press release.CEPR asked researchers at the MIT Election Data and Science Lab to independently verify their work on the 2019 Bolivian election.
