This paper determines whether gasoline income and price elasticities have changed. To do so, the paper considers a balanced, but particularly long (1960–2017) panel of 17 OECD countries. In addition, it employs two methods that vary to the extent that they allow for cross-sectional and time heterogeneity: rolling window, mean group regressions and time varying estimates. We find that the price elasticity increased in absolute terms during the energy crises (1973–1985), peaking thereafter and then becoming smaller. While income elasticities are not constant over time, they do not deviate much from time-invariant estimates. Similarly, price elasticities have been more or less stable for about the past two decades. This last finding suggests that the price peak of the 1970s-early 1980s had a permanent effect on demand that was not replicated during the more recent (i.e., centered around 2008), and similar in magnitude, price increase and fall.

本文确定汽油收入和价格弹性是否发生了变化。为此，本文考虑了一个由 17 个经合组织国家组成的平衡但特别长的（1960-2017 年）小组。此外，它采用了两种方法，它们在一定程度上允许横截面和时间异质性：滚动窗口、平均组回归和时变估计。我们发现，在能源危机期间（1973-1985 年），价格弹性绝对值增加，此后达到顶峰，然后变小。虽然收入弹性随着时间的推移不是恒定的，但它们与时间不变的估计值相差不大。同样，在过去的二十年左右，价格弹性或多或少是稳定的。
