There are many more Kofi Annans in Ghana and elsewhere who can lead Ghana. The problem in Ghana is not so much about a personality, even though bad political leadership has rubbed a lot of salt in our sores. It is about institution building and attitudinal changes. If we do not do this not even Jesus the Christ, who is generally considered and accepted as flawless, can do anything in Ghana. Let us minimize our religious and blanket faith in personalities and vouch for better institutions.
People come and go but good institutions endure.
The answer lies in the level and nature of time-honored institutions in those countries compared to ours. What institutions matter From political economy point of view, the important institutions include, among other things, independent judiciary, rule of law, and free press, political representation, free and fair elections, independent trade unions, social insurance, etc. Economists tend to look at the same institutional issues from a different angle. Thus for convenience and ease, I would like to look at these issues from an economist's perspective, but the institutions being discussed may serve both the needs of a market economy as well as non-market needs such as social stability and cohesiveness and social justice. Though institutions do not feature significantly in the training of economists, the importance of institutions in economic development has long been recognized by the profession such that now there is a whole field of Economics known as Institutional Economics solely devoted to the study of the impact of institutions on economic development.
