The Trajectory of the United States in the World-System: A Quantitative Reflection
Level 4 - case-series / case-control
Historical comparative quantitative analysis using secondary macroeconomic data (design analogy, non-clinical).
What was done
The authors used revised historical estimates of global gross domestic product (GDP), population, and GDP per capita from Angus Maddison (2001) to quantitatively re-examine the historical economic trajectory of the United States. They compared 20th-century U.S. economic hegemony against 17th-century Dutch and 19th-century British hegemonies and tracked the trajectories of competing challenger nations.
What was found
The abstract reports no numerical estimates, effect sizes, or specific quantitative results.
Why it matters
This work quantitatively contextualizes modern U.S. economic hegemony against previous historical global hegemonies to model patterns of long-term economic rivalry.
Limits
The abstract provides no empirical numbers or statistical results. The study relies entirely on secondary historical macroeconomic reconstructions, which carry substantial estimation uncertainty, and does not specify in the abstract which challenger states were assessed or the exact methodology used.
