The dataset is increasingly popular among economists, because it provides exogenous variations in whether or not a particular set of crops are cultivated.
- Nunn and Qian (2011) is a pioneer, estimating the impact of potato cultivation in Europe on population growth after potatoes were introduced from the New World.
- Costinot and Donaldson (2012) tests Ricardian trade theory of comparative advantage by observing relative productivity in producing different crops in each location.
- Costinot, Donaldson, and Smith (forthcoming in JPE) estimate the impact of climate change on agricultural markets by predicting the future agricultural international trade based on relative productivity of different crops in each location under climate change scenarios.
- Mayshar et al (2015) uses the suitability for cereal production to predict the emergence of the state.
