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,...

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...

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...

Pooling microdata from five Australian censuses, I explore the relationship between child gender and divorce. By contrast with the United States, I find no evidence that the gender of the first child has a significant impact on the decision to marry or divorce. However, among two-child families,...

How are hourly wages affected by the Earned Income Tax Credit? Two strategies are utilized to determine the relationship between the credit and hourly wages. First, I use variation in state EITC supplements, which magnify the effect of the federal EITC. I find that a 10 percent increase in the...

With many countries considering the adoption of a system of earned income tax credits, it is useful to analyze how different types of credits affect labor supply and earnings. This paper focuses on a 1999 reform to the UK tax credit system, which increased the value of the credit and reduced the...
