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
