Whereas the literature evaluating the effect of tort reforms has focused on reported incurred losses, this paper examines the long run effects using a comprehensive sample by state of individual firms writing medical malpractice insurance from 1984-2003. The long run effects of reforms are...

Forty years after the publication of the first systematic study of adverse medical events, there is greater access to information about adverse medical events and increasingly widespread acceptance of the view that patient safety requires more than vigilance by well-intentioned medical...

Using the best publicly available data on lawyers' liability claims and insurance – from the largest insurer of large law firms in the U.S., the American Bar Association's Standing Committee on Professional Liability, and a summary of large claims from a leading insurance broker – this...

Persistently high profits on “insurance” for small value losses sold as an add-on to other products or services (such as extended warranties sold with consumer electronics, loss damage waivers sold with a car rental, and credit life insurance sold with a loan) pose a twofold challenge to the...

This article reports and explains four key findings about the difference between the role of insurance in mass tort litigation and the role of insurance in ordinary tort and corporate governance litigation as reported in earlier research: (1) outside of the insolvency context, mass tort...
