I was casually browsing through Transparency International’s website, and noticed something peculiar – even though citizens of the Republic of Georgia have a much higher opinion of their country’s ability to deal with corruption in their country relative to their counterparts in the US, and a much more optimistic outlook on the future of public institutions, Georgia ranks 55th on the Corruption Perception Index (CPI), whereas the US ranks 19th (see 2013 rankings). Given the inherent difficulty in measuring actual levels of corruption, I understand why PERCEPTION of corruption is widely considered the best available proxy. But IF public perception is so important, I still didn’t understand why Georgia is 36 places lower than the US, when its citizens have a far more positive perception about their country’s ability to contain corruption in virtually every category measured.
I did a little digging and asking around, and I found that CPI rankings actually place LITTLE, IF ANY weight on public perception within the countries being ranked. If Wikipedia is accurate, CPI rankings are actually based on aggregates of “expert opinions” from select institutions that Transparency International (TI) deems “credible”:
“Transparency International commissioned Johann Graf Lambsdorff of the University of Passau to produce the Corruption Perceptions Index (CPI). The 2012 CPI draws on 13 different surveys and assessments from 12 different institutions. The institutions are the African Development Bank, the Bertelsmann Foundation, the Economist Intelligence Unit, Freedom House, Global Insight, International Institute for Management Development, Political and Economic Risk Consultancy, Political Risk Services, the World Economic Forum, the World Bank and the World Justice Project.”
On the other hand, there is a section in TI’s website that covers public opinion, known as the “Global Corruption Barometer” (GCB), from which I noticed the peculiar results in Georgia and the US. This inevitably made me curious about Chinese public opinion of their own institutions compared to that of Americans, so I found the latest dataset (2010/2011) in which both the US and China were included, and here are some excerpts of the survey results, along with my personal interpretation thereof. What I found so far is that IF public perception is supposed to be a good proxy for actual corruption, then one CANNOT conclude that corruption is somehow worse in China than the US, at least not if you’re to believe the citizens of each country.
