Resumen
Descripción
The demand for meat has been estimated by many studies utilizing various data and
estimation methods. In this study, we perform a meta-analysis of the income elasticity
of meat that involves regressing 3357 estimated income elasticities, collected from 393
studies, on variables that control for study characteristics. Across several meta-regression
specifications, we find significant differences in income elasticities tied to the type
of meat being studied, as well as a few functional forms, data aggregations, publication
characteristics, and locations of demand. However, many study characteristics do
not significantly influence reported income elasticities. Less concern should be given to
such characteristics when choosing an income elasticity from the literature.
