Some Inconvenient Truths about Climate Change Policy: The Distributional Impacts of Transportation Policies
模拟了四种交通政策，发现替代总量管制与交易的政策成本高出2.5到4倍，但因收益分配不均而更易被采纳；投票分析显示，地区从可再生燃料标准中获益越多，越不支持总量管制与交易法案，竞选捐款是部分原因。
Climate policy has favored costly measures that implicitly or explicitly subsidize lowcarbon fuels. We simulate four transportation sector policies: cap and trade (CAT), ethanol subsidies, a renewable fuel standard (RFS), and a lowcarbon fuel standard. Our simulations confirm that alternatives to CAT are 2.5 to 4 times more costly but are amenable to adoption due to right-skewed distributions of gains. We analyze voting on the Waxman-Markey (WM) CAT bill. Conditional on a district’s CAT gains, a district’s RFS gains are negatively correlated with the likelihood of voting for WM. Our analysis supports campaign contributions as a partial mechanism.
