Executive Summary
Joint roundtable discussion hosted by Georgist Journal in the lead-up to the 2012 Council of Georgist Organizations (CGO) Cleveland conference. Eight leading Georgist thinkers — including the three central cycle theorists (Gaffney, Harrison, Foldvary) — debate the reliability of the 18-year cycle, its predictive pitfalls, and the gap between academic acceptance and political adoption of the LVT remedy. The most important single piece for capturing intra-camp contradictions.
Key Claims & Positions
On cycle reliability
- Gaffney: “Moderately confident. History says people don’t learn; their lust for unearned increments takes them over after a while.” — confidence: high
- Harrison: “We can be sure of the repetition of the 18-year periodicity (+/-), subject to the absence of relevant overwhelming shocks to the capitalist order [world war, OR reduction in privatised rental flows].” — confidence: high (position piece)
- Foldvary: “The average period, 18 years, could well be a coincidence. While the 18-year duration from 1990 led to an accurate prediction for 2008, I think the period can be different, and was different sometimes, so we should not get too hung up on the number 18. It is an average, probably nothing much more than that.” — confidence: high (CRITICAL — Foldvary himself flags the “average not a law” caveat)
On anomalies
- Gaffney: Why was there no crash in 1911? — “the rise of property taxes and frequent reassessments” led by Richard Hurd, Lawson Purdy, Tom Johnson, Hazen Pingree, Taylor, Dunne et al. (KEY evidence for property-tax-as-cycle-stabilizer thesis.)
- Gaffney: 1857–1873 cycle only 15 years despite Civil War; anomaly not fully explained.
On pitfalls / self-critique
- Harrison: “They shoot the messengers of bad news. There is also the problem of relying just on history to repeat itself. Without a theoretical underpinning, the skeptics can get away with saying ‘the future will be different this time.‘”
- Gaffney: “Pitfalls can be found in making it rote, by the calendar, without looking at particulars of the time. Crying wolf discredits one worse than not crying at all. This happened to Ravi Batra, 2000.”
- Foldvary: “It is simplistic, if we expect it to make precise predictions.”
On mainstream adoption
- Harrison: cites Mark Dampier (Hargreaves Lansdowne, £10bn AUM), John Calverley (Standard Chartered), Vince Cable MP as mainstream adopters.
- Harrison: “Which brings me to the question: what is the role of this idea in the Georgist movement? None. The Georgist movement is locked in a time warp, collectively lacking the imagination and drive to exploit the economic crisis to advance the agenda of fiscal reform.” — Scathing internal critique.
Mechanism Discussions
- Lindy Davies challenge: the natural-agricultural-cycle explanation seems implausible in a global industrial-farming era — what’s the real cause?
- Harrison claims to have attempted a theoretical formulation; Two Georgist economics professors disagree with it “without offering reasons for rejecting my hypothesis.”
- Open question (from Davies): “What is so powerful about the 18-year pattern that could allow it to recur under so many different sets of influences?”
Notable Quotes
“How sure are we about the 18-year cycle in the 21st century? What’s the reliable evidence?” — Lindy Davies [framing question]
“None of the responses to this latest crash alters the DNA of the capitalist system. So there is no reason to believe that past history won’t be repeated.” — Fred Harrison
“The 18-year period is just a statistical average.” — Fred Foldvary
Concepts Referenced
