In response to Ray, Non-working women are likely to have husbands who earn more than the husbands of working women (all else equal) - this says the probability of a woman working increases with a *decrease* in *husband* income. But the finding is that the probability of a woman working increases with an *increase* in the *sister's husband's* income. Two different results.
