Alex Tabarrok on the Economics of Medical Malpractice

Episode Summary

Executive Summary: Russ Roberts and Alex Tabarrok examine the economics of medical malpractice and argue that rising malpractice premiums are mainly driven by higher jury and settlement awards, not insurer price gouging. They show how elected judges, local jury composition, and legal incentives create large state-to-state differences, contributing to defensive medicine, strained doctor-patient relationships, and calls for tort reform.

Main Topics: Rising malpractice premiums and doctor dissatisfaction (Priority: 5/5): Doctors face sharply higher liability insurance costs, especially in high-risk specialties, which squeeze incomes and make medical practice more stressful and bureaucratic. Why premiums rise: payouts, not gouging (Priority: 5/5): Tabarrok argues that premiums largely track expected payouts from settlements and verdicts; insurer profits are not rising and competition constrains pricing. Political and judicial factors in award levels (Priority: 5/5): Elected judges, especially partisan elections, and lawyer-funded campaigns are associated with higher awards, suggesting legal institutions shape liability costs. State and county variation in malpractice awards (Priority: 4/5): Awards differ dramatically across states and counties, with higher verdicts in some jurisdictions due to local political and demographic factors rather than medical differences. Defensive medicine and overdeterrence (Priority: 4/5): Fear of lawsuits encourages unnecessary tests and procedures, including more C-sections, which adds cost and may reduce patient welfare. Reform ideas: caps, specialization, and contracts (Priority: 4/5): Tabarrok favors specialized courts/juries and stronger enforcement of ex ante contracts or arbitration to improve accuracy and reduce randomness in outcomes.

Key Arguments: Malpractice premiums have risen dramatically since about 1999, in some specialties and states by 50%-100% or more, creating real pressure on doctors. The main driver of premium increases is higher tort awards and settlements; insurers must price for expected payouts. Price-gouging claims are weak because insurance company profits have not risen and some firms have exited the business. Competition means long-run premiums tend to track payouts dollar-for-dollar; if prices were persistently too high, new firms would enter. States with elected judges, especially partisan elections, tend to have higher awards because judges respond to voters and lawyer campaign contributions. Jurisdictions with higher poverty tend to return larger awards for similar cases, making outcomes highly location-dependent. A small number of outlier verdicts can drive much of the national premium increase and create very uneven risk across states. The civil justice system is a poor compensation mechanism because large shares of awards are consumed by legal and administrative costs. The system also does weak deterrence because random awards hit good and bad doctors alike, while encouraging defensive medicine. Defensive medicine, including excess testing and higher C-section rates, can harm patients and raise healthcare costs. Specialized courts or juries could better distinguish negligence from bad luck, especially in complex medical cases. Respecting ex ante contracts and arbitration agreements could move dispute resolution away from unpredictable judge/jury decisions.

Data Points: Malpractice premium increase since 1999: 50%-70% in some specialties/states; in some cases 100%+ - Doctors have seen sharply rising liability insurance costs over recent years. Internal medicine premium: About $10,000 per year - Example of a relatively lower-risk specialty. OBGYN premium: About $50,000 per year; in some states $100,000-$150,000 - Example of a high-risk specialty with much higher liability costs. Premium doubling example: From $50,000 to $100,000 in five years - Illustrates rapid cost escalation for some doctors. Long-run relationship between payouts and premiums: One-to-one - Tabarrok argues premiums eventually track claims payouts due to competition. Pennsylvania vs. Wisconsin premiums: About 6 times higher in Pennsylvania - Used to show large state-level variation unrelated to medical quality. Judge-election effect on awards: $35,000 higher on average - States with elected judges, especially partisan elections, have higher awards. Campaign funding from lawyers: 80%-90% - In states with partisan judicial elections, judges’ campaign funds often come from lawyers. Award levels by county poverty rate: About $500,000 at 4% poverty vs. about $2 million at 25% poverty - Shows that jury generosity rises with county poverty levels. Philadelphia million-dollar verdicts (1999-2001): 81 verdicts over $1 million - Philadelphia alone produced almost as many large verdicts as all of California. California million-dollar verdicts (1999-2001): 101 verdicts over $1 million - Comparison point showing Philadelphia’s unusually high verdict concentration. Plaintiff recovery after costs: Less than half retained; about 60 cents on the dollar lost to lawyers/administration - Illustrates inefficiency of the tort compensation system. C-section variation: About 30% in some counties vs. 5% in others - Example of how defensive medicine and practice style vary widely across jurisdictions.

Pivotal Quotes: "medical liability reform is their top priority" — Russ Roberts quoting the AMA: Introduces the claim that malpractice premiums and lawsuits are threatening patient access to care. "if premiums were above payouts, you have competition, you have free entry, you have other firms entering industry" — Alex Tabarrok: Explains why insurance prices should converge toward expected losses over time. "The civil justice system is a good method of compensation? And the answer is, unfortunately, it's terrible." — Alex Tabarrok: Summarizes his critique of tort law as an inefficient compensation mechanism.

Implications: Listeners should expect malpractice costs to vary widely by jurisdiction and legal structure, not just medicine. Reform efforts that improve predictability—specialization, arbitration, and limits on awards—could reduce defensive medicine and lower costs.
