“…While the cross-border spillovers purportedly created by Chinese city and provincial governments have been much discussed, the potential impact on Chinese commercial interests policy intervention by US state, city, and town governments is barely remarked upon or studied. 1 This is curious given that a new dataset on business incentives offered by US state and local governments has been made available (Bartik, 2017) which, in turn, has been a contributing factor in stimulating a wave of research on the domestic impact of such policy intervention (Suarez Serrato and Zidar, 2016;Ossa, 2018;Slattery, 2018;Chava et al, 2019;Fajgelbaum et al, 2019;Slattery, 2020;Slattery and Zidar, 2020). 2 My focus here on the potential adverse cross-border spillovers created by US sub-national governments should be put in its appropriate global context.…”
