From The Undercover Economist by Tim Harford:
We all know that in most countries the Ministry of Defense is in charge of attacking other countries and that the Ministry of Employment presides over the unemployment lines. Cameroon’s Ministry of Tourism is in that noble tradition. Its job is to discourage tourists from getting into the country.
But I don’t want to give too much credit to the Ministry of Tourism. Discouraging tourists is a real team effort. According to Transparency International, Cameroon is one of the most corrupt countries in the world. In 1999, it was the most corrupt country surveyed. When I visited in 2001 it was the fifth most corrupt, an improvement much celebrated by the government. A moment’s reflection should tell you that earning the title of ‘Most Corrupt Country in the World’ takes some effort. Because Transparency International ranks countries based on international perceptions of corruption, a winning strategy is to concentrate on screwing bribes out of foreign businessmen — for instance, at the airport. But the Cameroon authorities have spread themselves too thin, because Cameroon is massively corrupt at every level and does not just target foreigners. Perhaps it’s this lack of focus that caused them to slip from the top spot.
