Analysis: High-cost blood cancer drugs deliver high value

A recent study published in Blood found that most breakthrough blood cancer therapies have favorable cost-effectiveness ratios, with some treatments providing better value than others. The median ratio for industry-funded studies was $26,000/QALY, while non-industry-funded studies had a median ratio of $33,000/QALY.

Cooperation, considered

A new model developed by Harvard researchers explains how motives impact cooperation and why people trust genuine altruists over those who open envelopes. The 'envelope game' helps capture the notion that people value principle-driven behavior, especially in situations where cooperation comes with a cost.
