We contribute to the still limited literature concerning the role of individual subjective well-being (SWB) on
fertility, conducting a study by child parity with the German Socio Economic Panel (GSOEP) data.
The analysis shows that the impact of SWB on childbearing decisions is only significant (and sizeable) for
the second child. This result is relevant not only because confirms that in a context such the German one,
where Total Fertility Rate (TFR) is now as low as 1.4 (and been so for the last decade), the decision to have
the second child is the crucial one for the targeting of family policies, but also because it shows the relevance
of SWB in the design of these policies..
Furthermore, our findings are particular robust: thank to the rich and long longitudinal data of the GSOEP,
we are able to measure the effect of SWB on the temporally subsequent fertility behavior, eliminating the
tricky issue of the reverse causality and carefully controlling that such effect would not be caused by the
effect of personality traits (the “big five” traits, here PT) both with SWB and fertility. This specific result
assures that – nevertheless PTs are a strong component of SWB variability – the effect of SWB on fertility is
not determined by PTs, leaving therefore room for adequate policy measures aimed to rise individual SWB,
which in turn would sustain fertility.
