. . . A unique data set of internet searches on Google and Yahoo is compiled using alternate variations of “corruption”, “bribery” and “country name” keywords to capture internet corruption awareness. Results show that internet hits about corruption per capita correlate negatively with corruption perceptions and corruption incidence. This finding generally holds for different specifications and other robustness checks.
That is the abstract of the paper "The internet as an indicator of corruption awareness" by Goel, Nelson, Naretta (September 2011).
