Encouraging democracy is one goal of most industrialised nations’ foreign economic policies. Formulating such policies requires an understanding of the political-economy logic governing democratic transitions. This column describes an important recent advance in theoretical thinking on the military’s role.

According to theory, demands for democratic change are more likely to be realised during economic downturns, which lower the cost of overthrowing autocrats. This column presents empirical evidence from Sub-Saharan Africa suggesting that recessions may indeed open a window of opportunity for democratisation.

Having too few members of parliament means parliament is likely to be un-representative, but it seems that having too many makes it easy for vested interests to buy influence. Simple logic suggests that the optimal number of MEPs should be proportional to the square root of the population. Empirical work suggests that nations with a much higher number of MEPs tend to be plagued by red-tape and corruption.

Arriving at the optimal number of representatives in a democracy involves a trade-off between the need to keep decision costs down (i.e. limiting the number of representatives involved in the decision-making process) and ensuring that the decisions made truly reflect the preferences of the citizens.

Written in September 2005: There is much to celebrate in spreading democracy around the world, but the empirical evidence suggests that it is not very important for economic success. The clear positive wealth-democracy correlation seems to arise since democracy is more likely to persist as a country grows richer.
