[Considerations concerning a mathematical model for the analysis of repeated legal abortion]

The phenomenon of an increase in repeat abortion following the legalization of abortion is examined. In particular, the author describes the mathematical model developed by Tietze to analyze repeat abortions following liberalization of abortion law. An attempt is then made to expand the Tietze model. "Repeat abortions are disaggregated by order terminations, the number of prior legal abortions. The purpose is also to show that the effects of heterogeneity might not be valid. Furthermore it must be noticed that, for some order terminations, abortion rates are not always increasing until a steady state is reached." (summary in ENG, FRE)
