However, in developing countries, where child labor is an indispensable source of household income, parents actually incur a negative cost by having an extra child, so that the trade-off disappears. The purpose of this paper is to restore the Beckerian quantity\u2013quality trade-off when intergenerational transfers are upstream, in order to keep fertility endogenous. We do that by adding a negative \u201csibship size effect\u201d on human capital formation to the standard Becker model. With a simple specification, we obtain multiplicity of steady states or, more fundamentally, the possibility of a jump from a state with high fertility and low income to a state with low fertility and high income, triggered by a continuous increase in the productivity of human capital formation.<\/jats:p>","DOI":"10.1017\/s1365100515000255","type":"journal-article","created":{"date-parts":[[2015,10,16]],"date-time":"2015-10-16T09:18:04Z","timestamp":1444987084000},"page":"2046-2066","source":"Crossref","is-referenced-by-count":8,"title":["ENDOGENOUS FERTILITY WITH A SIBSHIP SIZE EFFECT"],"prefix":"10.1017","volume":"20","author":[{"given":"Elise S.","family":"Brezis","sequence":"first","affiliation":[]},{"given":"Rodolphe Dos Santos","family":"Ferreira","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2015,10,16]]},"reference":[{"key":"S1365100515000255_ref42","doi-asserted-by":"publisher","DOI":"10.1177\/036319909301800101"},{"key":"S1365100515000255_ref39","unstructured":"Okpukpara Benjamin Chiedozie and Ngozi Odurukwe (2006) Incidence and Determinants of Child Labour in Nigeria: Implications for Poverty Alleviation.
