Technology Adoption and Early Network Infrastructure Provision in the Market for Electric Vehicles
利用挪威422个市镇2010-2017年数据，研究发现电动汽车充电站存量与销量存在非线性关系，早期基础设施供给能有效促进电动汽车采纳，支持针对早期基础设施的政策。
We document non-linear stock effects in the relationship linking emerging technology adoption and network infrastructure increments. We exploit 2010-2017 data covering nascent to mature electric vehicle (EV) markets across 422 Norwegian municipalities together with two complementary identification strategies: control function regressions of EV sales on flexible polynomials in the stock of charging stations and charging points, and synthetic control methods to quantify the impact of initial infrastructure provision in municipalities that previously had none. Our results are consistent with indirect network effects and the behavioral bias called "range anxiety," and support policies targeting early infrastructure provision to incentivize EV adoption.
