Changing Parental Leave and Shifts in Second and Third-Birth Rates in Austria

We analyse the effects of changes in parental leave regulations in Austria in 1990, 1996and 2002 on second and third-birth rates. These changes determined both the length ofparental leave and the possibility for its prolongation in case of subsequent pregnancy. Weconstruct monthly duration and order-specific fertility rates and parity progression ratios tostudy both short-term shifts in period second and third-birth rates and the trends in cohortparity progression ratios among women affected by changing leave regulations. Theextension of parental leave from one to two years in 1990, which created an incentive forwomen to have their subsequent child within 26 months, led to an immediate and markedincrease in second and third-birth rates at intervals 21-26 months after the previous birth.De facto shortening of paid leave in 1996 generated a sharp increase in second and thirdbirthrates at shorter intervals of 15-20 months. Although we find clear evidence ofimmediate changes in birth spacing that are in line with the ‘logic’ of the new leaveregulations, this discontinuity in childbearing patterns did not have any discernable impacton the overall second and third-birth cohort progression rates or on period fertility trends.As in most cases analysed for other developed countries, the main effect of the policychange was on the tempo of fertility, namely on the spacing of second and third births.
