Inter-municipal cooperation cloud and tax administrative costs

Abstract

The influence of inter-municipal cooperation (IMC) on municipal finances remains underexplored. This study focuses on implementing the inter-municipal cooperation cloud (IMC cloud), a pioneering digital framework that facilitates cooperation among municipalities in Japan. The findings indicate that introducing the IMC cloud results in a decrease of approximately 5% in tax administrative costs. A further examination reveals that the IMC cloud offers returns to scale via cost sharing and promotes operational improvements, thereby driving savings in tax administration costs. These findings suggest the possibility that cost savings through operational improvements are an overlooked aspect in the existing studies on municipal collaboration context.
