Network Diffusion of Green Technology in Post-Fukushima Japan

We study the diffusion of adoptions of green technologies in Japan after the 2011 Fukushima incident. We find that, on average, municipalities within a 120 km radius of a given nuclear power plant adopted green technology at a higher rate than those outside that radius. We then rely on a network diffusion model to analyze the direction, speed, and order in which municipalities adopted said technology. Next, we perform a counterfactual analysis by targeting key spreaders to alter the diffusion process. Finally, we propose a novel targeting method accounting for possible "bottlenecks" preventing the propagation process in the network.
