Male Organ and Economic Growth: Does Size Matter?

The abstract of a new paper by Tatu Westling of the University of Helsinki:

This paper explores the link between economic development and penile length between
1960 and 1985. It estimates an augmented Solow model utilizing the Mankiw-Romer-Weil
121 country dataset. The size of male organ is found to have an inverse U-shaped
relationship with the level of GDP in 1985. It can alone explain over 15% of the variation in
GDP. The GDP maximizing size is around 13.5 centimetres, and a collapse in economic
development is identified as the size of male organ exceeds 16 centimetres. Economic
growth between 1960 and 1985 is negatively associated with the size of male organ, and it
alone explains 20% of the variation in GDP growth. With due reservations it is also found
to be more important determinant of GDP growth than country’s political regime type.
Controlling for male organ slows convergence and mitigates the negative effect of
population growth on economic development slightly. Although all evidence is suggestive
at this stage, the `male organ hypothesis’ put forward here is robust to exhaustive set of
controls and rests on surprisingly strong correlations.
