How algorithmic decision tools impact consumer welfare
Comments to the FTC on algorithmic decision tools, artificial intelligence, and predictive analytics
Miranda Bogen, Aaron Rieke, and Hannah Masuga
CommentsWe offered comments to the Federal Trade Commission on the implications of algorithmic decision tools used in consumer advertising and marketing campaigns. We made several recommendations to the FTC:
Lack of visibility into online advertising practices and technologies is an impediment to effective consumer protection. The FTC should encourage digital ad platforms to open all ads and targeting criteria to public scrutiny.
Advertising algorithms can play a meaningful role in discriminatory advertising, separate and apart from advertiser targeting choices. The FTC should encourage further study, particularly as to how ad platform optimization relates to equitable delivery of ads for credit, housing, and employment.
Many companies claim to be using social media data to help make important decisions about consumers, despite platform policies that prohibit such uses. The FTC should consider investigating companies that violate platform policies in ways that might harm consumers.

In The Atlantic, we argue that digital platforms — which deliver exponentially more ads than their newsprint predecessors — are making core civil-rights laws increasingly challenging to enforce.
Across the FieldOur empirical research showed that Facebook itself can skew the delivery of job and housing ads along race and gender lines, even when advertisers target broad audiences.
Across the FieldOur empirical research showed that Facebook’s “Special Audiences” ad targeting tool can reflect demographic biases. We provide experimental proof that removing demographic features from a real-world algorithmic system’s inputs can fail to prevent biased outputs.
Across the FieldOur empirical research showed that Facebook’s ad delivery algorithms effectively differentiate the price of reaching a user based on their inferred political alignment with the advertised content, inhibiting political campaigns’ ability to reach voters with diverse political views.
