Alex Tabarrok on Innovation

Episode Summary

Executive Summary: Alex Tabarrok argues that U.S. innovation has been held back by overbroad patents, weak K-12 schooling, misdirected college incentives, and a regulatory state that makes new firms, infrastructure, and research harder to launch. He calls for narrower patents, better-paid and better-tested teachers, more apprenticeships and STEM focus, freer high-skill immigration, and a policy shift from warfare/welfare toward an innovation state.

Main Topics: Patent reform and cumulative innovation (Priority: 5/5): The conversation centers on how patents can encourage innovation in some areas but increasingly impede follow-on innovation in software, business methods, and other cumulative fields. Tabarrok favors shorter, more flexible patents and narrower patentability rules. Education system failures and alternative pathways (Priority: 5/5): Tabarrok argues that U.S. K-12 and higher education are misaligned with innovation: dropout rates remain high, vocational and apprenticeship pathways are underdeveloped, and college is overly treated as the default route to success. College major mix and STEM underproduction (Priority: 4/5): The speakers discuss how student preferences have shifted toward arts, communications, and psychology while STEM fields have stagnated, despite society’s need for more technical talent and innovation capacity. Government priorities: warfare/welfare versus innovation (Priority: 4/5): Tabarrok says U.S. budgets and politics emphasize transfer payments and defense rather than long-run growth, and he wants a reorientation toward basic science, research, and innovation-friendly public policy. Regulation, venture capital, and barriers to startup growth (Priority: 4/5): The discussion highlights how layered regulation, Sarbanes-Oxley, and legal uncertainty make it harder for startups to go public or for new infrastructure to be built, reducing dynamism and venture capital effectiveness. Immigration and the supply of talent (Priority: 3/5): Tabarrok briefly argues that the U.S. makes it too hard for high-skilled immigrants to enter, even though attracting top talent would directly strengthen innovation and entrepreneurship.

Key Arguments: Innovation should be increased because productivity growth is the main driver of living standards; even if innovation feels strong, the U.S. can do better. Patents are justified where imitation is cheap and R&D costs are very high, but a one-size-fits-all 20-year patent term is inefficient. In fields like software and business methods, broad patents raise transaction costs and give older patent holders veto power over new innovation. Big firms can accumulate patent arsenals for defense, but this creates 'IP feudalism' that especially harms small firms and potential disruptors. Much innovation occurs without patents, as shown by roses, fashion, sports strategy, and Walmart’s operational improvements. Teacher quality matters, but U.S. K-12 suffers because smart people have more attractive alternatives; teacher pay and accountability need to rise together. The U.S. overvalues college as the main form of education, while apprenticeship and vocational programs can better fit many students and labor-market needs. College major choice is distorted by grade inflation and status incentives; more students choose easier-to-grade fields rather than socially valuable technical fields. Government should shift resources from warfare and welfare toward basic research, science, and innovation-oriented institutions. Too many regulations and veto points create large cumulative barriers that slow down infrastructure, firm formation, and experimentation. High-skill immigration should be expanded because it is one of the most obvious and underused levers for innovation.

Data Points: U.S. productivity growth trend break: Below trend since about 1973 - Tabarrok cites the 'great stagnation' and says productivity growth has been below its 1947-1973 trend since roughly 1973. High school completion by age cohort: People age 55-64 are slightly more likely to have a high school education than those age 25-34 - Used to illustrate that U.S. educational attainment among younger cohorts is unusually weak compared with other countries. Male high school dropout rate: 25% - Tabarrok says about a quarter of U.S. males drop out of high school. Teacher supply shift: About half of college-educated women became teachers in the 1970s; by 1980 about 30% of entering MBAs/doctors/lawyers were women - He uses this to argue the pool of teacher talent changed as women gained more opportunities elsewhere. Walmart sales: About half a trillion dollars annually - Tabarrok uses Walmart as an example of major innovation outside patent-heavy sectors. Consumer savings from Walmart: Estimated at about a quarter of a trillion dollars annually - Illustrates large productivity gains from retail innovation. Walmart patents: About 60 patents - Supports the claim that a hugely innovative company can operate with relatively few patents. Pharmaceutical R&D cost: About $1 billion to create a new pharmaceutical - Used as the classic case where patents are most defensible. Imitation cost for drugs: Second pill costs about 50 cents - Highlights why imitation is cheap relative to original invention in pharmaceuticals. Patent term: 20 years - Tabarrok criticizes giving the same patent duration to very different inventions. Computer science graduates: More graduates 25 years ago than today (slightly more today in absolute terms, but not by much) - He argues STEM output is flat despite growth in the economy and tech sector. Visual and performing arts graduates: More than computer science, chemical engineering, and microbiology combined; doubled over 25 years - Shows the shift away from technical fields. Psychology graduates: Doubled over 25 years; more graduates than available psychology jobs nationally - Used to argue many students choose majors with weak labor-market demand. Government science budgets: About $30 billion for NIH and NSF combined (as cited) - Compared with much larger spending on defense and transfer programs. Big budget share: Defense, Social Security, Medicare, and Medicaid are roughly 60-70% of the budget - Illustrates the 'warfare welfare state' framing. High-skill visas: Lottery visas outnumber visas for people of extraordinary ability - Supports the claim that U.S. immigration policy is misallocated.

Pivotal Quotes: "Innovation is one of those things that more is better." — Alex Tabarrok: Used early in the discussion to justify why slower productivity growth matters. "We’re seeing kind of an IP feudalism." — Alex Tabarrok: His phrase for a patent landscape where large firms accumulate arsenals and smaller firms are blocked from innovating. "It’s a way of making innovation easier. It’s a way of lowering the cost of your innovation." — Alex Tabarrok: Explaining why limiting broad patents helps innovators rather than merely taking away rights.

Implications: The episode argues for a broad pro-innovation agenda: narrower patents, stronger and more accountable schooling, more apprenticeships, STEM emphasis, easier high-skill immigration, and less regulatory friction. Listeners should see innovation as a systems problem, not just a tech-sector problem.
