The third birth in Sweden.
"This paper considers the formulation, estimation and interpretation of microdynamic models of fertility.  Our model explains parity choices, sterility, childlessness, interbirth intervals and initiation of pregnancy within a unified framework.  We develop a general methodology for estimating the determinants of transition times to births of different orders. Our procedure incorporates time-varying explanatory variables and unobservables.  We present conditions that justify conventional formulae relating hazards to survivor functions when time-varying variables enter hazards.  We also consider the validity of widely-used piecemeal estimation strategies that focus on one birth at a time.  We consider methods for selecting a best model among a class of non-nested models.  Two criteria are set forth and used to evaluate the determinants of third births in Sweden."
