On October 22-26 and December 1 and 3, CLDP, in collaboration with the Department of Justice and the Federal Bureau of Investigation, conducted a series of trainings on investigative techniques for staff from the Dominican Republic’s (DR) competition authority (Procompetencia). Procompetencia requested the training to improve their staff’s interview and interrogation skills so that they are better able to conduct effective investigations of collusive activity in the procurement system. Despite the government’s efforts to ensure open competition in the public procurement system, significant challenges remain, including the prevalence of bid-rigging, cartels, and other anti-competitive practices. These practices often prevent U.S. and foreign companies from receiving contracts. CLDP organized these sessions as part of a broader programming effort to increase transparency and competition in the DR’s public procurement systems.
