Professor Qianxue Zhang (GraSPP, the University of Tokyo): Resilient Innovation through knowledge diffusion under trade shocks
I develop a new model where sectoral knowledge diffusion affects the optimal innovation of firms during trade shocks. In the model, large firms and small firms compete in the market, with only large firms engaging in innovation. Changes in trade costs influence market concentration, which in turn alters the level of knowledge diffusion. The impacts on innovation depend on pre-shock level diffusion rates, with sectors that exhibit higher rates being less affected by trade cost changes. Despite the positive correlation between diffusion and innovation, this suggests that sectors with higher diff...

Masanori Matsuura (IDE-JETRO): Collective reputation and externalities in agriculture: Lessons from Fukushima nuclear accident
Negative externalities undermine collective reputation. Despite recent empirical attention to the impact of collective reputation on economic activities, very little is known about the effects of the reputational loss on input decision-making of suppliers. We document the reputational loss in the context of a sensational issue that affected the Japanese agrarian sector in 2011 due to the Fukushima Nuclear Accident. Using farm household-level agricultural census and a difference-in-differences approach, we identify substantial reputational impacts on non-contaminated areas within Fukushima pref...
