This paper studies the effect of legal origins (common law vs. civil law) on contemporary slum formation in developing countries. First, we provide a cross‐country correlation analysis. Second, we provide a regression discontinuity analysis using household data from Cameroon. The results suggest that a common law heritage is associated with a lower probability of slum conditions. The legal philosophies transplanted through colonization appear to be associated with the pattern of contemporary urban housing stocks in developing countries.

The COVID-19 pandemic was associated with short-term air quality improvements in many countries around the world. We study whether the degree of democracy and political institutions played a role. We provide novel empirical evidence from 119 countries. A given stringency of COVID-19 containment and closure policies had a stronger effect on air quality in more democratic countries, and in countries with majoritarian rather than proportional electoral rules. Our estimates suggest that the improvement in air quality was around 57% greater in majoritarian systems than in proportional systems. Confidence in government, trust in politicians, and social capital also affected outcomes.

A speedy response made a significant difference to the number of infections and deaths due to COVID-19. Did legal philosophies matter for policy responses? We find that when 100 cases had been diagnosed (and 7–14 days thereafter), common law countries had implemented weaker measures than civil law countries. However, no significant difference is found for COVID-19 related deaths. Lower vulnerability is also associated with weaker policies.

How does the historical legacy of agriculture affect democratic traditions in contemporary societies? This paper provides empirical evidence that inherent crop yield and democracy exhibit an inverted U-shaped relationship. This finding is supported by cross-country data from up to 147 countries, 186 pre-colonial societies, and the U.S. states. The relationship thus exhibits a highly persistent pattern. Crop yield is measured by kilocalories per hectare per year under rain-fed conditions, which has the advantage of being highly exogenous. The hump-shaped relationship holds up to a battery of robustness tests. (JEL O11, O13)
