Hmm…I had just been thinking about related ideas:
Sudanese billionaire Mo Ibrahim (of Celtel fame) has created a $5 million dollar cash prize for Africa’s most effective head of state.
year the winning leader will, at the end of his term, get $5m (Â£2.7m)
over 10 years and $200,000 (Â£107,000) each year for life thereafter.
"We need to remove corruption and improve governance," Mr Ibrahim said.
…The Mo Ibrahim Prize for Achievement in African Leadership will
be launched in London on Thursday… It will be available only to a
president who democratically transfers power to his successor. Harvard
University will do the measuring to see just how well the president has
served his or her people during their term in office.
Here is more, and thanks to Pablo for the pointer. The prize sounds too small, relative to the lure of corruption, but I see no reason not to try this idea.
