中文摘要
加快电力输电投资可能降低总成本，并促进可再生能源并网。本文记录了美国两个主要市场中由市场整合不完全所导致的静态配置低效率；这一低效率随时间上升，2022年总计达20亿美元。本文还论证了估计企业层面影响的重要性，因为在位企业可能有能力阻挠新建输电线路及其他改革。本文表明，如果市场实现整合，2022年4家企业的净收入合计将减少13亿美元，且有报道称其中部分企业正在阻挠输电项目。(JEL D22, D24, L13, L94, Q42, Q48)
Abstract
Accelerated investment in electricity transmission could reduce total costs and enhance renewable integration. I document static allocative inefficiencies induced by incomplete market integration in 2 major US markets; these have risen over time and totaled $2 billion in 2022. I also argue that estimating firm-level impacts is important, as incumbents may have the power to block new lines and other reforms. I show that 4 firms would have experienced a collective $1.3 billion drop in net revenues in 2022 had the market been integrated, and there are reports of some of these firms blocking transmission projects.
