Fertility and Parental Labor-Force Participation: New Evidence from a Developing Country in the Balkans * (First Draft) Iva Trako September 6, 2015 Abstract This paper examines the effect of fertility on parental labor-force participation in a developing country. In order to address the potential endogeneity in the fertility decision, I exploit Albanian parental preference for having sons as an exogenous source of variation. Using a repeated cross-section, I find that having an additional child has a positive and statistically significant effect on parental labor-force participation. IV estimates for mothers show that they increase labor supply, especially in terms of hours worked per week and the likelihood of working off-farm. Similarly, father’s likelihood of working off-farm and having a second occupation increase as a consequence of further childbearing. The heterogeneity analysis suggests that this positive effect might be the result of two plausible mechanisms: childcare provided by non-parental adults in extended families and greater financial costs of feeding more children.
