Study finds women directors damage profits

"We show that female directors have a significant impact on board inputs and firm outcomes. In a sample of US firms, we find that female directors have better attendance records than male directors, male directors have fewer attendance problems the more gender-diverse the board is, and women are more likely to join monitoring committees. These results suggest that gender-diverse boards allocate more effort to monitoring. Accordingly, we find that chief executive officer turnover is more sensitive to stock performance and directors receive more equity-based compensation in firms with more gender-diverse boards. However, the average effect of gender diversity on firm performance is negative. This negative effect is driven by companies with fewer takeover defenses. Our results suggest that mandating gender quotas for directors can reduce firm value for well-governed firms."

Use a better, non-restricted PDF reader? :S
This result would be unsurprising in, say, the 1970's, but in 2009, it is somewhat mystifying, though perhaps the median age of corporate directors is still high enough that an older generation is the norm, before many women enrolled in MBA programs or had lengthy corporate careers.
Also consider that the gender gap will likely not disappear for a long time, if ever. Many extremely smart, well-educated women leave the workforce for a period of time because they place the opportunity of raising one or more children above the opportunity to use their skill to continue the corporate war to the top. All else being equal, someone who leaves for a number of years before returning will have a tougher time making it to the top than someone who does not leave.
This could partly explain why although there are more women graduating with undergraduate degrees than men, roughly one third of MBA students are women.
It will be interesting to see what ratio the senior execs drift toward as institutional sexism begins fading with older generations. Probably not 50:50, but maybe closer to what's seen at MBA schools.

In fact, they also say that female directors were a benefit to "poorly-managed" companies. So, one thing you might claim is that this fits in with the general theory that the performance of men has a higher standard deviation than the performance of women.
From the abstract: "This negative effect is driven by companies with greater shareholder rights. In firms with weaker shareholder rights, gender diversity has positive effects."
That seems to be the key sentence. Although I am not certain, it seems likely that it is board interference with already effective management, not the presence of woman, that forms the causal link here.
- Companies in trouble might turn to women as board members. Women executives are still mostly outsiders. They might be more likely to join (or be solicited to join) the board of a company doing poorly.
- It's pretty well established that men are more comfortable with high risk -- sometimes to their detriment. Perhaps those companies with more female board members are less profitable but they go bankrupt less often.
- It might be that companies start thinking about board diversity once they've plateaued.

You don't have much experience with women.
Really, I couldn't decide from the article, but we've seen q good number of big companies recently that looked quite profitable until they went spectacularly bust.
This is a textbook example of the media (and the submitter) jumping on correlation and confusing it with causation. Women represent a tiny minority of board members overall, and it's reasonable to assume that the old boys' network would be strongest among the wealthiest and most powerful boards. This demonstrates nothing but that the glass ceiling cracks on the lowest levels first.
It may be that the preference is rational, but this study provides no evidence to prove that assertion.
Also, I personally did not confuse correlation with causation, see my earlier comment. Sufficient correlation suggests further possibilities and questions of causation. The researchers' quotations strongly suggests they too did not confuse correlation with causation.
Regardless of who is responsible, the title remains factually, objectively incorrect.
(An older version of) the actual study is here:

The abstract is:
Although some argue that tokenism drives the selection of female directors, we show that they have a significant impact on measures of board effectiveness. In a large panel of data on publicly-traded firms from 1996-2003, we find that (1) the likelihood that a female director has attendance problems is 0.29 lower than for a male director, (2) male directors have fewer attendance problems the greater the fraction of female directors on the board, (3) firms with more diverse boards provide their directors with more pay-performance incentives, and (4) firms with more diverse boards have more board meetings.
We also show that the positive relationship between corporate performance measures and gender diversity documented by previous studies is not robust to attempts to address the endogeneity of diversity. Instead, the average effect of gender diversity on both market valuation and operating performance appears to be negative. This negative effect is driven by companies with greater shareholder rights. In firms with weaker shareholder rights, gender diversity has positive effects. Our results suggest that diverse boards are tougher monitors. Nevertheless, mandating gender quotas in the boardroom may not increase board effectiveness on average, but may reduce it for well-governed firms where additional monitoring is counterproductive.
The fact that diverse boards perform better than homogeneous boards where shareholder rights are weaker seems consistent with the hypothesis that the diminished performance of women directors is stress and contention based: perhaps the tensions between the male and female members of the board, the CEO, and the shareholders, are more difficult to work within than if the board needn't bow to the shareholders as much.
Hm. Let's think about this. Perhaps if AIG had more women on the board, they would have been more closely "monitoring" all the exposure the company had in its insurance of mortgage-backed securities. So maybe AIG would not have made so much money in that line of business prior to the collapse of those assets, but perhaps they also would not have needed a huge government bail-out either. Just speculating here...
The study claims that women on boards tend to monitor more closely and perhaps that's because they are more risk-averse. I can't see that as always being a bad thing. Could be taken too far, but surely it's been lacking in recent times.
Here is a great piece on AIG's collapse, it was previously on HN, and is the best article about it I've read yet: http://www.vanityfair.com/politics/features/2009/08/aig20090...

Most "studies" don't even have an experimental design, so they need work right from the beginning.
Of course, one can point out that they aren't doing randomized trials, but that seems a touch unreasonable to demand.

I didn't have time to read the actual paper. I'm guessing the paper ignores any other context aside from hard numbers within a specific time period; so long term plays (with short term losses) are ignored.
edit: It is because they're forced to wear pants by a chauvinistic structure.
