Empirical evidence that migrants send home more remittances after disasters raises the question of whether remittances are used to self-insure, substituting for both formal and informal insurance. We investigate this question using a unique dataset on the usage patterns of financial services by...

Using census-based data on the ability to recall one's age, we show that low levels of nutrition impaired numeracy in industrializing England, 1780 to 1850: cognitive ability declined among those born during the Napoleonic wars. The effect was stronger in areas where grain was expensive and...

Age data frequently display excess frequencies at round or attractive ages, such as even numbers and multiples of five. This phenomenon of age heaping has been viewed as a problem in previous research, especially in demography and epidemiology. We see it as an opportunity and propose its use as...

Age data frequently display excess frequencies at attractive numbers, such as multiples of five. We use this "age heaping" to measure cognitive ability in quantitative reasoning, or "numeracy". We construct a database of age heaping estimates with exceptional geographic and temporal coverage,...

This study is the first to explore long-run trends of numeracy for the period from 1820 to 1949 in 165 countries, and its contribution to growth. Estimates of the long-run numeracy development of most countries in Asia, the Middle East, Africa, America, and Europe are presented, using...
