Notes: (i)The "Trust" index is the response to the question whether most people can be trusted. The index takes values 0-1 with 1 indicating more trust; (ii) climatic suitability is a geospatial index of the suitability of land for agriculture based on ecological indicators of climate suitability for cultivation such as growing degree days and the ratio of actual to potential evapotranspiration; (iii) soil suitability is a geospatial index of the suitability of land for agriculture based on ecological indicators of soil suitability for cultivation, such as soil carbon density and soil pH; (iv) adjusted climatic (soil) suitability is the cross-country weighted average of climatic (soil) suitability. The weight associated with a given country represents the fraction of the year 2000 population that can trace its ancestral origins to the given country in the year 1500; (v) the set of continent dummies includes a …xed e¤ect for Africa, Asia, Australia, Europe, North America, South America, Oceania and Sub-Saharan Africa; (vi) the set of geographical controls includes log average ruggedness, log average elevation, log absolute latitude, log access to navigable waterways and a …xed e¤ect for landlocked country and island; (vii) the set of legal origins dummies includes a …xed e¤ect for British legal origin, French origin, German origin, Scandinavian origin and Socialist origin; (viii) the set of major religion shares dummies includes a …xed e¤ect for Catholic share, Muslim share, Protestant share, and other religious shares; (ix) the set of European colony dummies includes a …xed e¤ect for British colony, French colony, Spanish colony, other European colony and non-colony; (x) robust standard error estimates are reported in parentheses; (xi) *** denotes statistical signi…cance at the 1 % ** at the 5%, and * at the 10%, all for two-sided hypothesis tests.

Summary: This table explores the validity of the estimation. In particular Column (1) estimates a logit model. Column (2) explores the slavery channel by controlling for ancestry adjusted strati…cation in the year 1 CE. Column (3) explores the trade channel by controlling for diversity in land suitability. Column (4) introduces an OPEC dummy in the analysis to capture resource rich countries with very low land productivity. Column (5) is censoring the sample by excluding countries with extremely low natural land productivity. The baseline analysis controls for geography, adjusted years since the Neolithic transition, ethnic fractionalization, quality of institutions, disease environment, schooling, and …xed e¤ects for legal origin, dominant religion shares, European colony, individual control (age, gender, education, religious group) and unobserved continental …xed e¤ects.
