Abstract

This study investigates the dynamic connectedness across nine economic policy uncertainty indexes. Our results indicate that the total spillover index is on average 67.4%, indicating a high level of interconnectedness across the nine indexes. In particular, the EU is the largest transmitter of uncertainty connectedness. In addition, China becomes a net transmitter of connectedness during the global financial crisis and European debt crisis. This finding indicates that the uncertainty of Chinese economic policy is an important contributor to the connectedness of the uncertainty network.
