Equity effects of energy affordability interventions
比较了价格上限和一次性转移支付两种政策在帮助低收入家庭支付基本用电方面的公平性，发现一次性转移支付更有利于低收入群体，并给出了两种政策效果相等的条件。
This paper compares the distributional effects of price cap and lump sum transfer policies to aid the affordability of subsistence electricity consumption. A lump sum transfer is more progressive than a comparable price cap on all units of electricity. We identify conditions under which these policies have equal distributional effects. We prove that both interventions are progressive.
