Sectoral productivity convergence, input-output structure, and network communities in Japan

We study sectoral productivity convergence in Japan through the input-output structure of the economy and its network representation.

Industrial Productivity Divergence and Input-Output Network Structures: Evidence from Japan 1973–2012

The paper evaluates the input--output structure of Japan through the lens of a community-detection algorithm from network theory. Results suggest the existence of two input--output network structures: a stationary community and a transitional community. Also, industrial divergence and instability in community membership are not necessarily indicative of low productivity performance
