西北大学的Diego R. Känzig、Luca Zanotti和哈佛大学的James H. Stock犯了一个基本错误，他们只关注油价上涨带来的集中利益，却忽视了分散的成本（“分析：油价冲击可能使美国变得更强大”，《美国新闻》，10月7日）。
Northwestern University’s Diego R. Känzig and Luca Zanotti and Harvard’s James H. Stock commit an elementary error by focusing on the concentrated benefits of higher oil prices while overlooking the diffused costs (“Analysis: Oil Shock Could Make U.S. Stronger,” U.S. News, Oct. 7).
他们展示了能源行业的集中利益，如更高的利润率和更多出口，但就止步于此。他们本应继续分析，因为他们忽略了落在每个人身上的分散成本。人们为与伊朗战争前相同能源量支付更多费用，可用于其他方面如食品、住房和投资的剩余资金减少。
They show the concentrated benefits to the energy industry, such as higher profit margins and more exports, but they stop there. They should have kept going, because they missed the diffuse costs that fall on everyone else. People are paying more for the same amount of energy as before the Iran war, and they have less left over for other things such as food, housing and investment.
