Path-Dependent Fiscal Adjustment: Divergent State Strategies in Post-Recession UI Trust Fund Management

How do states with different approaches to fiscal management adjust their unemployment insurance (UI) trust funds following a major economic shock? Using panel data from all fifty states spanning 1990–2019, this study uses interrupted time series analysis to examine changes in UI trust fund solvency and the fiscal strategies states used during the post-Great Recession period, a period marked by both severe fiscal stress and a tightening of federal lending criteria under revised Department of Labor regulations. Results show a significant reversal of pre-recession declines in trust fund solvency across states. However, the mechanisms of adjustment varied systematically based on initial solvency levels, revealing deep institutional path dependence. States with historically lower trust fund solvency achieved improvements primarily through benefit erosion, while states with stronger pre-crisis reserves relied on tax base growth. These findings suggest that the institutional orientations documented in prior research shape not only steady-state policy positions but also how states adjust under economic pressure. The divergent adjustment paths raise concerns about long-term program sustainability.
