Executive Summary

Homer Hoyt’s landmark 1933 University of Chicago dissertation, documenting 100 years of land values in Chicago (approximately 1830–1930). This is the original empirical foundation for the 18-year real estate cycle thesis. Hoyt tracked land sale prices, building permits, and economic activity across a full century of Chicago data and identified the recurring ~18-year pattern of boom, bust, and recovery. Every subsequent cycle researcher (Harrison, Anderson, Foldvary, Gaffney) builds on Hoyt’s data.

Key Findings

  • The ~18-year rhythm: Chicago’s land values rose and fell in approximate 18-year cycles from the 1830s onward
  • Land leading the cycle: Land values both led and amplified economic booms; the bust in land prices preceded economic recession
  • Banking connection: Credit expansion against rising land values was a consistent feature of each boom phase
  • Self-reinforcing dynamics: Expectation of future land appreciation drove speculative purchases, pushing prices beyond productive value

Historical Cycle Peaks Documented (approximate from Hoyt’s data)

  • 1818-19
  • 1836-37 (the “land mania” preceding the 1837 crash)
  • 1854-57
  • 1869-73
  • 1887-92
  • 1905-10
  • 1925-26 (predecessor to 1929 crash)

Significance

  • The founding empirical work — without Hoyt’s 100-year dataset, the cycle thesis has no historical depth
  • Harrison’s Boom Bust (2005) and Anderson’s Secret Life (2008) both explicitly extend Hoyt’s analysis to modern data
  • Foldvary’s 1997 prediction was partially grounded in Hoyt’s historical pattern evidence
  • Harrison devoted an entire chapter to correcting the interpretation of Hoyt’s work (“The Hoyt Heist”) — arguing that Hoyt’s own employer/funders subsequently buried the cycle finding
  • The Chicago data provides the longest continuous series: ~100 years of empirical verification before any modern researcher began studying the cycle

About Homer Hoyt

  • Received his PhD from the University of Chicago in 1933 for this dissertation
  • Later worked for the Federal Housing Administration (FHA), where he developed the “sector theory” of urban land use
  • The “Hoyt Heist” accusation (by Harrison): Hoyt’s FHA employers wanted to promote mortgage lending; the cycle thesis was inconvenient; Hoyt’s later career minimized the cyclical findings
