Abstract

This is a comment on “Ramadan fasting, sex-ratio at birth, and birth weight: No effects on Muslim infants born in Germany” [Economic Letters, 2015] DOI http://dx.doi.org/10.1016/j.econlet.2015.10.015. We show that due to some methodological aspects the main conclusions of the above mentioned paper should be a little bit altered.
