The laws of economics say that people act out of rational and self-serving motives. But what would it say about the self-sacrificing gestures we make for family and friends? On an inquiry into why people invest in their children in 2000, neuroeconomist Paul Zak discovered the hormone oxytocin, a chemical released when petting dogs, nursing children, or cuddling with loved ones. Since then, Zak has conducted a series of studies to conclude that increased oxytocin leads to increased generosity, and feelings of trust, empathy, and overall happiness. His findings also look at the effects of testosterone versus oxytocin in the workplace, and offers solutions like on-site daycare to boost trust- and, therefore, productivity and morale- in public and work settings.
