This paper analyses the impact of elections, partisan and political support effects on the dynamics of human development in a panel of 82 countries over the period 1980-2013. A GMM estimator is employed and the results point out to the presence of an electoral cycle in the growth rate of human development. Majority governments also influence it, but no evidence is found regarding partisan effects. The electoral cycles have proved to be stronger in non-OECD countries, in countries with less frequent elections, with lower levels of income and human development, in presidential and non-plurality systems and in proportional representation regimes.
