We estimate the impact of annual obstetricians and gynecologists' conferences on births in Australia and the United States. In both countries, the number of births drops by 2-4 percent during the days on which these conferences are held. Since it is unlikely that parents take these conferences...

We estimate the impact of annual obstetricians and gynecologists' conferences on births in Australia and the United States. In both countries, the number of births drops by 1 to 4 percent during the days on which these conferences are held. We argue that for this reason professional obstetrics...

There is a commonplace notion that full moons affect natality and mortality. To test this theory, we obtain daily births and deaths data from Australia, covering all 10,592 days from 1 January 1975 to 31 December 2003. We find that full moons are not associated with any significant change in the...

It is well understood that government policies can distort behaviour. But what is less often recognized is the anticipated introduction of a policy can introduce its own distortions. We study one such “introduction effect”, using evidence from a unique policy change in Australia. In 2004,...

Using data on births from Australia, we estimate the level of patient bargaining power in negotiations over birth timing. In doing so, we exploit the fact that parents do not like to have children born on the “inauspicious” dates of February 29 and April 1. We show that, in general, the...

How much do non-medical factors affect the timing of conceptions, births and deaths? To test this, we estimate the effect of the millennium on conceptions, births and deaths. With a highly flexible empirical specification, we find large and significant increases in conceptions and births, and...

In 1979, Australia abolished federal inheritance taxes. Using daily deaths data, we show that approximately 50 deaths were shifted from the week before the abolition to the week after (amounting to over half of those who would have been eligible to pay the tax). Our results imply that over the...
