Boundary Effects in the Diffusion of New Products on Cartesian Networks
研究了城市边界附近居民因邻居较少而降低太阳能安装率的边界效应，通过二维网络巴斯模型和实际数据验证，发现边界对个体采用有显著影响但对整体采用率影响可忽略。
The Role of Boundaries in the Spreading of Solar Peer effects by neighbors play a key role in the spreading of residential solar. Thus, people are more likely to install a solar system on their roof if some of their neighbors have already done so. Because people who live near the municipality boundary have fewer neighbors, does this imply that they are less likely to adopt solar? In “Boundary Effects in the Diffusion of New Products on Cartesian Networks,” Fibich, Levin, and Gillingham analyze this problem analytically using the Bass model on two-dimensional networks and empirically using data on installations of solar systems. They show that boundaries have a significant impact on the adoption of residential units near the municipality boundary. Their effect on the aggregate adoption in the municipality, however, is negligible.
