Parenthood postponement is a key demographic trend of the last three decades. In order to rationalize that stylized fact, we extend the canonical model by Barro and Becker (Econometrica 57:481–501, <CitationRef CitationID="CR1">1989</CitationRef>) to include two—instead of one—reproduction periods. We examine how the cost structure...</citationref>

We explore the optimal fertility timing in a four-period OLG economy with physical capital, whose specificity is to include not one, but two reproduction periods. It is shown that, for a given total fertility rate, the economy exhibits quite different dynamics, depending on the timing of births....

Phelpsís (1961) Golden Rule states an unambiguous relationship between optimal capital intensity and fertility: a rise in fertility decreases the optimal capital intensity, because a higher fertility increases the investment required to sustain a given capital to labour ratio (i.e., the capital...
