題目: Supply Chain Disruptions: Evidence from the Great East Japan Earthquake

概要: Exploiting the exogenous and regional nature of the Great East
Japan Earthquake of 2011, this paper provides a systematic
quantification of the role of input-output linkages as a mechanism for
the propagation and amplification of shocks. We document that the
disruption caused by the earthquake and its aftermaths propagated
upstream and downstream supply chains, affecting the direct and
indirect suppliers and customers of disaster-stricken firms. We then
use our empirical findings to obtain an estimate for the overall
macroeconomic impact of the shock by taking these propagation effects
into account. We find that the propagation of the shock over
input-output linkages can account for a 1.2 percentage point decline
in Japan's gross output in the year following the earthquake. We
interpret these findings in the context of a general equilibrium model
that takes the firm-to-firm linkages into account explicitly.

題目: 集積の経済・生産性と品質改善

概要: Analysis of the urban agglomeration of economic activity has
focused on its benefits for firm productivity. But the marginal-cost
savings which agglomeration brings about also free up inputs that can
be used to produce higher-quality goods, with their own profitability
potential. We use plant-product-level data from Japanese manufacturing
to examine agglomeration's influences on product quality. Results
confirm that quality does grow with region size, suggesting polices
aimed at encouraging urban agglomeration improve competitiveness by
raising product quality as well as productivity. Total factor
productivity alone, therefore, underestimates agglomeration benefits
by ignoring the quality incentives that accompany it.
