Uau! Este é um dos posts mais importantes que eu já coloquei neste blog (graças a uma dica do blog do Prof. Greg Mankiw). O original do post (publicado no dia 04/03) está no blog do próprio Fama (http://www.dimensional.com/famafrench/2010/03/my-life-in-finance.html).
Tem momentos na nossa vida que são marcados por fatos que ficarão para sempre. A vida de um grande profissional, quando contada por meio de suas constribuições, é um destes momentos raros. Ler sobre a vida de um grande profissional é mais que um aprendizado; é uma lição sobre o futuro!
Estou pensando este post como uma lição para meus alunos (e para aqueles que não são) e colegas, uma vez que raramente a gente vê um relato auto-biográfico de tamanha densidade!
Como estou envolvido neste momento em defender que os ativos de tecnologias de informação e comunicação (TICs) são equivalentes a quaisquer ativos financeiros, já que configuram retornos esperados…

Dear Deputy Prime Minister,
Earlier this week in your capacity as Minister of Women’s Affairs you sponsored research on the causes of the gender wage gap in New Zealand.
That just published research was seriously incomplete. The Ministry of Women’s Affairs advised today that they were aware of the work of Claudia Goldin but did not reference it.
MWA ignored the research of the world’s top female labour economist Claudia Goldin. Her research shows that the causes of the gender wage gap are completely different to what you have suggested in the research you launched earlier this week and calls for novel policy solutions that are in a completely different ballpark to those that you have raised this week.
When education and accumulated job experience faded away as the statistical explanation of the causes of the gender wage gap, which the research you launched confirmed, Goldin explored how the organisation of work drove what remains. She called this the last chapter of the gender wage gap.
She found that jobs where the willingness to work very long hours, very specific hours and/or maintain continuous contact with co-workers or clients are highly prized and disproportionately rewarded was central to explaining the gender wage gap for well-paid workers.
Both her research and that you sponsored this week shows that the gender wage gap is close to zero for the bottom half of the wage distribution but the wage gap is 20% or more for professionals in the top 10% of wage earners.
Rather than hypothesise that employers suddenly develop an unconscious bias against successful career professionals because they are female, Goldin looked deeply into how the organisation of work and design of jobs affected how workers were paid and how women made choices about their careers and what they majored in at university in anticipation of these demanding or rat race jobs.
Goldin referred to pharmacy as the most family friendly occupation in America because pharmacists are completely interchangeable and in America the great majority of them are employed by Walmart and other big companies. Few are self-employed. The only advantage of working long hours in the pharmacy profession is you are very tired at the end of the week.
Goldin contrasted that with law or finance sector jobs which are rat race jobs.
Rat race jobs such as these disproportionately reward people who are willing to work very long hours, work very rigid hours and/or show up whenever the client wants them anywhere in the world. These jobs also severely penalise even the shortest interruption in your career track. You come back reporting to the people you hired 12-24 months ago!
After starting on the same pay, large gender wage gaps in high-powered professional occupations emerge after 5-10 years into a career as successful professionals power up to become partners or highflyers.
Importantly, Goldin found one counterfactual to this large wage gap for high-powered professionals. If your husband earns less, there is no wage gap with your MBA classmates at Harvard but you do work fewer hours per week.
Goldin’s study of the Harvard and Beyond longitudinal study was corroborated by a study she did of the top 100 occupations in the American Community Survey. The gender wage gap is limited to rat race jobs.
Goldin argued that the last chapter of the gender wage gap dependents on changing the way in which we organise work.
That is a profoundly ambitious agenda because much of the way in which high-powered professionals must work long hours and be always on call for clients is from the demands of their clients. For example, you want your lawyer to show up in court on time every time and always be available to you when you are in trouble. The legal system does not work in any other way because of the possibility of urgent applications to court etc.
Women anticipate this because, as an example, female surgeons tend to specialise in areas where they can schedule operations in advance rather than having to rush in to perform emergency surgery.
I suggest to you that you should think more deeply about the quality of advice you have just received from the causes of the gender wage gap in New Zealand.
That advice to you is profoundly at odds with the latest thinking in modern labour economics on what the causes are and what the solutions must now be for the last chapter of the gender wage gap.
A postscript has the key publications of Claudia Goldin to show why she is the world’s leading female labour economist without a doubt. You were not advised of her findings.

Geoff Simmons’ Friday Whiteboard podcast last night on the 12% gender wage gap was a good summary of the proximate drivers such as occupational segregation and part-time work. I have a few quibbles with his stress on unconscious bias as the driver of the gender wage gap.
The first of these quibbles is the gender wage gap is tiny at the bottom and even the middle of the labour market but is so high and so stable for so long at the top-end. Why does unconscious bias increase with the wages on offer? Better paid professional women have far more options to look around for the best paid job and turned down inferior officers.
My second quibble is the New Zealand gender wage gap…
