Transparency International is a non-governmental organization, headquartered in Berlin, with a mission to document and root out public corruption worldwide. The organization defines corruption as “the abuse of entrusted power for private gain. It can be classified as grand, petty and political, depending on the amounts of money lost and the sector where it occurs.”
For more than two decades Transparency International has produced an annual Corruption Perceptions Index. The most recent edition of the index (here) ranks 176 countries from the least corrupt to the most corrupt. The index ranges from a scale of 0 to 100, “where a 0 equals the highest level of perceived corruption and 100 equals the lowest level of perceived corruption.” The Index “aggregates data from a number of different sources that provide perceptions of business people and country experts of the level of corruption in the public sector.”
The least corrupt countries are Denmark, New Zealand, Finland and Sweden. They always stay at the top of the list. The most corrupt countries are Syria, North Korea, South Sudan and Somalia. Denmark’s score is 90 while Somalia’s is 10. The United States is number 18 on the list, with a score of 74, below Canada, Germany and the UK. That’s alarming. Not that the US is below other countries but that the US is more than halfway to the midpoint of the CPI scale (Slovakia and Croatia have scores of 51 and 49 respectively).
Corruption matters because it erodes public trust in government and business, and trust is very important for promoting economic growth and well-being. For example, note the following figure I produced showing the correlation between corruption and per capita gross domestic product. Of course, correlation does not mean causation. And we can debate whether corruption produces low growth or whether low growth invites corruption, but the correlation is stark. Highly corrupt countries are very poor. Moreover, for every 10 point improvement in a country’s perceived corruption, GDP per capita increases by more than $7,000 (that’s what the equation in the figure shows).
Transparency International also draws a connection between corruption and social inequality. As noted on their website (here): “it’s timely to look at the links between populism, socio-economic malaise and the anti-corruption agenda. Indeed, [US President] Trump and many other populist leaders regularly make a connection between a ‘corrupt elite’ interested only in enriching themselves and their (rich) supporters and the marginalisation of ‘working people’. Is there evidence to back this up? Yes. Corruption and social inequality are indeed closely related and provide a source for popular discontent. Yet, the track record of populist leaders in tackling this problem is dismal; they use the corruption-inequality message to drum up support but have no intention of tackling the problem seriously.”
In other words, we preach virtues but don’t practice them ourselves.
Which reminds me. After discussing these ideas in my applied ethics class I suggested that students can obtain an automatic A in the class if they leave me a $100 bill with their name written on it in pencil. Some students laughed while others wanted to negotiate the price. Apparently they didn’t learn anything.
