Businesses seeking licenses frequently encounter requests for bribes, with 60.9% reporting such approaches, and 46.9% admitting compliance. For government projects, under-the-table commissions of 11-15% are common, with cash, gifts, or sponsorships being the primary forms of payment.
The complexity of bureaucratic procedures (29.11%), legal loopholes (25%), and the avoidance of penalties (18.8%) are cited as key reasons for paying bribes. Lack of transparency in government bidding processes is another concern, with 27.3% of companies approached by intermediaries promising favorable outcomes.
Moreover, the survey reveals a deep-seated mistrust in the government's whistle-blower systems, as 52.3% of respondents lack confidence, and 43.7% are hesitant to report corrupt activities. This pervasive distrust underscores the challenges in combating corruption effectively.
