This paper should have been finished last January. But because of my other writing projects, I postponed the revision to two or three weeks ago. (So my readers may notice that I don’t reply much to comments or post anything new). I hope this paper would help foster a more sober dialogue on the RH Bill, because both pro- and anti-RH bill groups can use its theoretical framework to prove their statements that the more effective contraceptives would result to less abortions (pro-RH Bill) or more abortions (anti-RH Bill). Happy Feast of the Annunciation to all.
Here’s the abstract:
In this paper, we propose a set of hypotheses for deriving the abortion rate as a function of the intercourse interval in weeks, the number of weeks since the start of rst intercourse, the number weeks of pregnancy, the number of weeks of breastfeeding, and the contraceptive failure rate. We also propose risk compensation as feedback: the intercourse interval is proportional to the mth power of the contraceptive failure rate. We show that for dierent values of m, the abortion rate may become smaller, bigger, or remain the same compared to the case when no contraceptives are used. Thus, one way to settle the RH Bill debate is to determine the correct value of m derived from accurate data on the reproductive health
parameters of a large sample of the female population. If this data is not available, it is better not to take risk in approving the bill, because there is a possibility of increasing our national abortion rate through the promotion of contraceptives. Instead, it may be better to use alternative methods to manage our population and reduce our abortion rate to zero by promoting chastity before marriage, late marriages, and breastfeeding|and accepting each child conceived as a gift and not as a burden.
