Ethnic favouritism is widely regarded as an African phenomenon, or at most a problem of poor and weakly institutionalised countries. This column uses data on night-time light intensity to challenge these preconceptions. Ethnic favouritism is found to be as prevalent outside of Africa as it is within, and not restricted to poor or autocratic nations either. Rather, re-election concerns appear to be an important driver of the practice.

Current office-holders often seem to be re-elected quite easily, irrespective of their performance. This ‘incumbency advantage’ make it harder for first-time candidates and undermines democratic competition. This column proposes a new rule for re-election – the score-replication rule. In its simplest form, such a rule would require incumbents to obtain a percentage of votes at least as high as their highest historical election performance. This would restrain the negative incumbency advantage and potentially reduce policy polarisation.

Economists have long understood that policy chosen by politics is unlikely to be socially optimal. This is because politicians face the probability of losing power and may discount the future too much, or act to improve their re-election probability. This column explores these issues taking into account the fact that future government revenue is uncertain. Public income volatility acts to reduce the efficiency of public policy. This has important implications for developing countries that rely on income from volatile sources, such as natural resource extraction.

Brazil's elections this weekend are not expected to trouble financial markets, unlike some of the country's previous electoral episodes. This column attributes that to Brazil's embrace of pragmatic policymaking and stable democracy, which have made it a major player in the international economic and political arenas. Brazil is a power of the present.
