The graphic at the top right shows how the wealth of the tortfeasor would vary as a function of its care given the care level of the victim, the standards for liability, and the damages assessed in the event of liability. The graphic at the middle right shows how the wealth of the victim would vary as a function of its care given the care level of the tortfeasor, the standards for liability, and the compensation awarded in the event of liability. The graphic at the bottom right shows the losses to tortfeasor (gold) and victim (green) given their current behaviors.

The control on the top left lets you move a locator marked with an "s" to set the standards of care required of the tortfeasor and victim and a locator marked with a "b" to set the behavior of the tortfeasor and victim. The control shows the area of liability in a transparent purple and shows the best responses of both players to the complementary strategies by a green dot. By chasing the green dot with your "b," you can create a Nash equilibrium solution in which the behaviors of the players are mutual best responses to the others' strategy. The control at the bottom left lets you set the damages the tortfeasor will have to pay if found liable and the compensation the victim will receive if the tortfeasor is found liable. Both values are stated as a ratio of the true loss to the victim. Try to find standards of care for which the Nash equilibrium behaviors result in the lowest total losses from accidents.
