Title:Regime-Contingent Uncertainty Pricing: Strategic Risk, Liquidity, and Political Shocks

Authors:Scott Brown (University of Puerto Rico, scott.brown@upr.edu)

Description:This dataset accompanies the study "Regime-Contingent Uncertainty Pricing: Strategic Risk, Liquidity, and Political Shocks," which develops a theory of regime-dependent pricing of economic policy uncertainty (EPU) in U.S. equity markets. Using monthly data from 2009 to 2025, the analysis identifies nonlinear shifts in the EPU-return relationship during two major political-economic shocks: the COVID-19 pandemic and the 2025 U.S.–China Trade War. The study demonstrates that EPU effects on asset prices are not time-invariant but depend on macro-regime context, investor behavior, and liquidity conditions.

The repository includes:





Monthly return data for SPDR S&P 500 ETF (SPY)




U.S. Economic Policy Uncertainty Index (EPU) data




Python scripts for data processing, OLS estimation, and Markov-switching modeling




Figures and tables illustrating regime dynamics




A complete README with replication instructions



Key Contributions:





Demonstrates that financial market responses to EPU invert during structural crises (e.g., COVID-19) and revert during politically driven uncertainty (e.g., Trade War)




Advances dynamic capabilities and institutional theory by modeling uncertainty sensitivity as regime-contingent




Introduces the concept of "reactivated uncertainty sensitivity," emphasizing the return of classical risk pricing under renewed political stress



Keywords:Economic Policy Uncertainty (EPU), regime switching, COVID-19, U.S.–China Trade War, Markov switching model, strategic foresight, uncertainty pricing, institutional theory
