Against Intellectual Monopoly (Boldrin & Levine)

Summary

Against Intellectual Monopoly (Cambridge University Press, 2008) is a book by Michele Boldrin and David K. Levine, both economists (then at Washington University in St. Louis; Levine now UCLA/EUI). It makes the strongest published abolitionist case in modern economics: that patents and copyrights — what the authors deliberately rename "intellectual monopoly" — are not necessary for innovation and, as actually practiced, reduce it. The authors posted the full final text free on Levine's site before publication, and it remains freely downloadable chapter by chapter, which is why it can be quoted and re-checked here in full.[1]

On this wiki the book is carried as an attributed position, not as settled Geoist doctrine. It sits at the far, most-contested end of the rent gradient: a patent monopoly is the case where the rent is the intended incentive, so a claim that the rent is pure deadweight is exactly the claim the innovation objection exists to test. The book's value is that it assembles the empirical case that the incentive story is weaker than assumed — and its overreach is that it generalizes a real finding (IP mostly raises patenting, not invention) into a near-absolute abolitionism that most of the field, and this wiki, do not accept.

The Core Argument

Boldrin and Levine distinguish two things ordinary usage conflates. The right to sell what you create, and to keep the first-mover and know-how advantages that come with having created it, they endorse. The monopoly — the statutory right to control what others do with copies of the idea after sale — they reject. Their thesis statement:

"intellectual property is not necessary for innovation and as a practical matter is damaging to growth, prosperity and liberty."[1]

Their positive claim (Chapters 2–3, 6) is that competition already rewards creation: inventors and authors earn from lead time, learning-by-doing, reputation, complementary sales, and the sale of the first copies, all of which exist without a monopoly. Historical set-pieces carry the argument — Watt's steam engine (whose patent, they argue, retarded rather than advanced steam power), the early software industry, and open competition in fields from Italian opera to financial-derivative design. The monopoly, on their account, adds deadweight loss, litigation, patent thickets, and rent-seeking without adding a necessary incentive; their epigraph — "Monopoly corrupts, absolute monopoly corrupts absolutely" — states the register.[1]

Key Findings (verified quotes)

The empirical heart (Chapter 8). The chapter — titled "Does Intellectual Monopoly Increase Innovation?" — surveys the post-WWII econometric literature on whether strengthening patents raises innovation. Their summary of 23 studies:

"these studies find weak or no evidence that strengthening patent regimes increases innovation; they find evidence that strengthening the patent regime increases … patenting!"[2]

This is the load-bearing finding and the one most defensible independent of the book's abolitionism: the measured response to stronger IP is more patents, and — in initially weak-IP countries — more inward foreign investment in patent-intensive sectors, but not a demonstrable rise in the rate of invention or productivity.[2]

The industrial-history reading. Boldrin and Levine concede that establishing patents four centuries ago, against a baseline of "arbitrary seizure by the rich and powerful," was a step forward — but argue this does not license the modern "widespread and ever growing monopolistic rights."[2] They enlist economic historians against the North thesis that patents drove the Industrial Revolution, quoting MacLeod & Nuvolari that "it would be wrong to assume that the emergence of patent systems played a critical or determinant role in such a transition."[2] The same chapter draws on Petra Moser's economic-history work (most 19th-century innovation was never patented) as corroboration.

Pharmaceuticals (Chapter 9) — the hardest case, addressed head-on. The authors accept pharma is where their case is weakest (large sunk R&D, cheap imitation) but argue much pharma innovation is publicly funded, that patents distort research toward "me-too" and evergreening, and that alternatives (prizes, direct funding) could fund drug discovery without the monopoly. This is the chapter critics contest most sharply, and the wiki treats the pharma exception as genuinely open — see ip-rents Honest Limits.

What It Supports

• Intellectual-Property Rents — supplies the "the incentive story is weaker than assumed" strand: if stronger IP mostly buys more patenting rather than more invention, a larger share of IP income reads as capturable rent.
• Taxing Tech Rents — an Instrument Comparison — the IP row of that comparison rests on the possibility that the monopoly is often unnecessary, which is Boldrin & Levine's thesis at full strength.
• Rent-Seeking — the book's account of patent thickets, trolling, and defensive patenting as pure economic rent dissipation.

What It Cuts Against / Counter-position

The book cuts against the innovation objection only in its strong form — it denies that the IP prize is a necessary incentive at all. That strong denial is where serious critics push back, and the wiki records the pushback as part of the honest frame:

• The strong form overreaches on pharma. Where R&D is enormous and imitation is trivially cheap, the monopoly rent may be genuinely necessary to fund invention; Boldrin & Levine's alternatives (prizes, public funding) are promising but unproven at the scale required, and the book asserts more than the evidence settles here.
• "No evidence of an effect" is not "evidence of no effect." The 23-study survey shows the innovation response to stronger patents is hard to detect — which is consistent both with "patents don't matter" and with "the effect is real but swamped by noise and endogeneity." Reviewers in the Journal of Economic Literature (Richard Gilbert, 2011) and elsewhere read the same evidence as supporting reform (shorter terms, narrower scope, better non-obviousness standards) rather than abolition.[1][3]
• First-mover advantage is industry-specific. The book's positive mechanism (competition rewards creation via lead time) is strong in software and finance and weak exactly where imitation is instant and cheap — so its own logic implies a calibrated, sector-varying regime, not a blanket abolition.

The wiki's settled reading, per ip-rents: IP is a real, capturable rent, but the right instrument is calibrated term/scope plus prize-style alternatives, not abolition — and Boldrin & Levine mark the far pole of that debate, not its consensus.
