Stochastic convergence analysis of US state economic freedom sub-components: Evidence from unit root tests for bounded processes

This study tests for convergence of the three main sub-components of economic freedom (government spending, taxation, and labor market freedom) for the 50 US states from 1981 to 2019. In particular, we test for stochastic convergence using unit root tests that account for structural breaks and bounded processes. By controlling for these sources of parameter instability, we find limited evidence in favor of stochastic convergence across the three sub-components of economic freedom. However, we find more evidence of stochastic convergence with respect to the sub-components than in the case of the overall economic freedom at the US state level. Our results highlight the distinct nature of the institutional quality across states as represented by government spending, taxation, and labor market freedom.     

The convergence dynamics of economic freedom across U.S. states

This study tests for convergence in economic freedom across the 50 U.S. states from 1981 to 2019. In particular, we test for stochastic convergence in overall economic freedom using unit root tests that account for structural breaks and bounded processes, two sources of parameter instability. We find limited evidence of stochastic convergence. Further analysis of relative (club) convergence and weak σ-convergence rejects the presence of overall convergence in the panel of the U.S. states, but the emergence of two convergence clubs with respect to state-level economic freedom. The logit analysis of the determinants of the convergence clubs reveals that more prosperous states and states with a higher initial level of economic freedom have a higher probability of being in the club with more economic freedom. However, more racially diverse states have a lower probability of being in the club with more economic freedom.
