Abstract: The scope of this study is to investigate the convergence pattern of market power in two retail natural gas markets, namely residential and commercial, across the US states over the period Jan 1997–Dec 2020. Our analysis identifies one non-convergence and several spatial sub-convergence clubs within the US territory for both market segments. Several reasons such as demand characteristics and geographic proximity may explain the different clustering patterns among the spatial units.
