This paper empirically investigates the propagation of business sentiment within the EU and adds to the literature on shock
absorption via a common market's real economy. To this end, we combine EU-wide official business sentiment indicators with
world input-output data and information on indirect wage costs. Econometrically, we model interdependencies in economic activities
via input-output linkages and apply space-time models. The resulting evidence provides indication for the existence of substantial
spillovers in business sentiment formation. Accordingly, and highlighted by the estimated impacts of changes in indirect labour
costs, policy reforms aiming at increasing the resilience of the European single market need to take these spillovers into
account in order to increase its effectiveness.
