“Windows of Opportunity,” Revenue Volatility, and Policy Punctuations: Testing a Model of Policy Change in the A merican States

The growing evidence of policy change patterns characterized as punctuated equilibrium has increasingly directed the attention of policy scholars to the question of what factors cause them. The present study attempts to address this emerging question by developing a comprehensive, multifactorial model and testing it with state budget data. Specifically, based on theories of information processing and agenda setting, it develops a conceptual framework that models punctuated policy change as a function of two main factors: institutional friction (consisting of institutional constraints, legislative streamlining mechanisms, information‐processing capacity, and bureaucratization) and policy windows (consisting of revenue volatility, change in party control, and budget cycle). In doing so, the study pays special attention to cyclical revenue fluctuations whose effect has never been subject to empirical test. Regression analyses reveal that policy window factors including revenue volatility, changes in party control of the governorship and the House, and a budget cycle play an important role in creating policy punctuations.
