Penis size and economic growth (UPDATES)
Adam Smith had a penis, but to my knowledge, the world's most famous economist never wrote about it.
But his seminal work on economics, The Wealth of Nations, is so 1776.
Today, thanks to the world wide web and Google, those interested in either (or both) penis sizes and the global economy can find economic paperswith titles like this: Male Organ and Economic Growth: Does Size Matter?
(More from GlobalPost: Penis sizes worldwide: Yeah, there's a map for that)
Written by Tatu Westling at the Helsinki Center for Economic Research (and, yes, we're fact-checking), here's the paper's abstract:
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.

Update:
I had a brief email conversation this afternoon with the author of the paper, Tatu Westling. Here's a rough transcript:
Is this a serious economic study or a lighthearted parody?
It started as a half-serious attempt, but frankly speaking I did not expect the correlations to be so robust as they turned out to be. Hence the seriousness increased as the study proceeded, and I may submit it to an economics journal at some point. But seriousness does not imply that I believe in causality at this point.
How and why did you decide to cover this particular topic?
I saw the online "world penis size map" by accident, and immediately recognized an economic narrative. The paper resulted from pure curiosity to assess this peculiar link.
What reactions have you received from your colleagues and others about the paper?
Reactions have been both amused and serious. The latter means that some have speculated whether there is actually some causality or are the links completely spurious. It might evidently be either way.
What is the most surprising or interesting thing you learned about this subject?
The most perplexing issue was that the negative relationship between 1960-1985 growth rates and male organ was so robust in statistical sense, and even survived the region and polity controls.

Size does matter: New research insists there is a link between a country’s average penile length and its rate of GDP growth.
There is a strong correlation between a country’s GDP growth rate and average penile length. That’s according to new research undertaken by the University of Helsinki’s Tatu Westling, who explored the link between economic development in 121 countries and penile length between 1960 and 1985 in his report “Male Organ and Economic Growth: Does Size Matter?” The findings? When it comes to GDP growth, big is not necessarily better. Average is best. To be precise, 13.5 centimetres is the “GDP maximising size.”
Westling reported that countries that averaged smaller penis sizes grew at a faster rate than their larger rivals. Every centimetre increase in penis size accounted for a 5 to 7 percent reduction in economic growth. The study also revealed that overall GDP was at its highest in countries with average-sized penises. GDP falls away at the extremes of penis length, noted the report.
For the record, the country with the largest average penile length of the 121 studied was Zaire (17.93 centimetres). South Korea possessed the smallest average penile length – 9.66 centimetres. View all the data here.
- Top-line findings. “The size of male organ is found to have an inverse U-shaped relationship with the level of GDP in 1985,” insisted the report’s abstract. “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.”
“Somewhat surprisingly, male organ was a stronger determinant of economic development than country’s political regime type at the Polity IV autocracy democracy spectrum,” marvelled the report.
- Some fast-growing countries may be compensating for something. “The opening question to most undergraduate macroeconomics courses usually is, ‘Why are some countries rich and others poor?’ The lecturer will then probably dive into all of the usual suspects behind economic growth – natural resources, technological innovation, savings rate – without mention of perhaps the most primal of measurements: penis size,” joked Dino Grandoni at The Atlantic Wire, who dug down into the apparent link: “Penile length and income are both factors that contribute to an individual’s level of self-esteem, and if a person has more of the former, he’ll need less of the latter. Or, to put it in layman’s terms, some fast-growing countries may be compensating for something.”
- Feasible policy recommendations? Even the report questioned the practical helpfulness of the findings: “For obvious reasons the male organ narrative yields little in terms of feasible policy recommendations. Beyond mass [im]migration, not much can be done on the average size of male organ at the population level. Still, one practical and serious implication stands out. Namely, these findings spell trouble for countries with large male organs since they evidence both low levels and growth rates of GDPs.”
