How does the use of a product affect a group of individuals? Does it’s use cause harm to a subset, like adverse effects from a pharmaceutical product or improper design of a part on an automobile? Does the product itself lead to harm over time, like asbestos with a incubation time of 30 to 40 years? What loss is suffered if the product fails or causes harm? We examine both the biometric risk of an impact on an individual and the potential economic loss if a product is found to be harmful. We also help in examining insurance issues, such as allocation between insurers, product versus nonproduct liability, and determining the possible risk for an insurer when a class of persons harmed might file suite.
