Bureaucrats’ Perception of Corruption and Political Trust in South Korea* Eunjung Choi** Jongseok Woo*** This article examines how government officials’ perceptions of corruption affect the evaluation of government effectiveness and political trust and whether the outcomes are different from ordinary citizens. On the one hand, one may expect that bureaucrats share with citizens the belief that perceptions of corruption harm their evaluations of government effectiveness and trust in government because they are also members of the society. On the other hand, bureaucrats may be more tolerant of corruption than ordinary citizens 669 *** This work was supported by the University of South Florida’s 2014 New Researcher Grant (number: 00000098980). *** Eunjung Choi is a visiting professor in Government and International Affairs at the University of South Florida.
