The poverty effect of democratization
研究了民主化对贫困率的影响，发现选举民主在短期内使贫困率下降11-14%，但长期效果不显著，表明仅选举民主不足以明确减少贫困。
In this paper we examine the interrelatedness between regime types of democracy and non-democracy and poverty reduction. The liberal international order and democratic principles have been challenged by the populace’s general discontent in recent years, while the reduction of poverty is a central goal of the global development agenda as embodied by the Sustainable Development Goals. Democracies could promote poverty reduction by encouraging redistribution, lifting barriers for poor people, or giving better access to the institutions of society. Democracies might hinder poverty reduction if they are captured by elites or become dysfunctional in general. Our data cover around 140 countries and a period from 1980–2018. We use a mix of methods to address endogeneity concerns. In dynamic panel estimates that control for past influences of poverty, GDP and inequality we find no significant impact of democratization – measured mainly by electoral democracy – on poverty rates. In more flexible and causal treatment effects estimates we find democratization reduces poverty rates by about 11–14% in the first five years after democratization on a 95% significance level and about 20% 10–14 years after democratization on a 90% significance level. Although we find mixed results, we are still confident that democratic political institutions matter greatly, and societies are better off when the political systems are more inclusive. The fact that our results do not find clear support for this suggest that electoral democracy – without further aspects considering the level of democracy – does not have a clear-cut effect on poverty.
