Between economic growth and stable democracy The correlation between development and democracy was first noted by the sociologist Seymour Martin Lipset in the late 1950s, and ever since then there have been many studies linking development to democracy.25 The relationship between growth and democracy may not be linear--that is, more growth does not necessarily always produce more democracy. The economist Robert Barro has shown that the correlation is stronger at lower levels of income and weaker at middle levels.26 One of the most comprehensive studies of the relationship between development and democracy shows that transitions into democracy from autocracy can occur at any level of development but are much less likely to be reversed at higher levels of per capita GDP.27 Whereas growth appears to favor stable democracy, the reverse causal connection between democracy and growth is much less clear. This stands to reason if we simply consider the number of authoritarian countries that have piled up impressive growth records over recent years--South Korea and Taiwan while they were ruled dictatorially, the People's Republic of China, Singapore, Indonesia under Suharto, and Chile under Augusto Pinochet. Thus, while having a coherent state and reasonably good governance is a condition for growth, it is not clear that democracy plays the same positive role.
