Amazon's Algorithm Favours Its Own Products Over Cheaper Alternatives

ProPublica found that Amazon's buy box algorithm often selects Amazon's own products or those of sellers who pay for its services, even when cheaper options exist. This results in customers paying higher prices, with an average difference of $7.88 per product. Sellers who do not pay for Amazon's Fulfilled by Amazon programme are disadvantaged and may lose sales. Amazon states that the algorithm considers factors beyond price, such as shipping speed and customer service.

Uber's Secretive 'Upfront Fares' Algorithm Cuts Driver Pay in Many Cities

Uber introduced an opaque algorithm called 'Upfront Fares' to calculate driver pay in 24 U.S. cities, replacing the previous time-and-distance-based rate. Drivers report lower and unpredictable earnings, with Uber taking a larger cut of fares. The company claims the change gives drivers more control, but critics say the secrecy makes it impossible to verify fair pay. The algorithm may learn the lowest rate drivers will accept, potentially driving down wages.

DC attorney general sues 14 landlords over RealPage rent collusion

The Attorney General of Washington DC filed a lawsuit against 14 large landlords, alleging they used RealPage's YieldStar software to form “a District-wide housing cartel” that artificially inflated rents. The complaint claims RealPage's pricing algorithm used data supplied by the landlords and pressurised them to follow its rate recommendations, with one firm's internal presentation stating at least 95% compliance was expected. This alleged scheme caused residents to pay millions of dollars above fair market prices during a housing affordability crisis.

Durham Police uses Experian Mosaic data in HART AI risk tool

Durham Constabulary developed the Harm Assessment Risk Tool (HART), a machine learning algorithm that assesses the recidivism risk of offenders. The tool uses 34 data categories including criminal history, age, gender and two types of postcode, one sourced from Experian's Mosaic marketing segmentation system. Big Brother Watch alleges that using such commercial consumer behaviour data to inform custody decisions risks prejudice and disproportionate targeting of deprived neighbourhoods. The force has stated it is refreshing the model with an aim to remove one of the postcode predictors.

Booking.com says it has worked to implement the commitments agreed with the CMA.

AMS algorithm lacks transparency and may discriminate against job seekers

The Austrian Public Employment Service (AMS) uses an algorithm to classify job seekers into categories A, B, and C, determining their access to benefits and training. Scientists from TU Wien, WU Wien, and University of Vienna have criticised the algorithm for lacking transparency, as only two of 96 model variants have been published. They allege that the system may discriminate against women and people with migration background, and that job seekers are not informed about how the algorithm works or given a chance to appeal.

Trivago loses Australian appeal over misleading hotel rate rankings

The Federal Court of Australia has dismissed Trivago's appeal against a ruling that the online travel company breached Australian consumer law. The court found that Trivago's website used an algorithm that gave prominence to hotels paying higher fees, so the most prominent offers were not always the cheapest for consumers. Consumers may therefore have paid more for rooms, and hotels lost direct bookings. The case returns to the Federal Court for consideration of penalties and other orders sought by the Australian Competition and Consumer Commission.

Allstate's proposed retention model charged big spenders more in Maryland

Allstate proposed an auto insurance rate adjustment plan in Maryland using a retention model algorithm that varied premium changes based on existing premiums. The algorithm would have increased rates up to 20% for customers already paying the highest premiums while capping increases at 5% for others, and would have denied meaningful discounts to thousands owed reductions. The Maryland Insurance Administration rejected the plan as discriminatory, but Allstate claims it was withdrawn and has continued proposing similar models elsewhere. The proposal never took effect in Maryland.

New York City's McKinsey-led jail violence program manipulated data, violence increased

New York City paid McKinsey & Company $27.5 million to reduce violence at Rikers Island jail complex. McKinsey designed a predictive algorithm called the Housing Unit Balancer and Restart housing units, but jail officials and McKinsey consultants stacked the units with compliant inmates to artificially lower violence numbers. Violence actually increased by nearly 50% during the project. The city eventually decided to close Rikers.
