¶ … Economists Have to Say About Gasoline Price Elasticity In contemporary society, the price of gasoline often appears to change in a fickle manner and most often seems unrelated to any real world global events as might be expected. Charging higher taxes for gasoline is considered a dubious strategy by many people since not everyone affected by the tax increase can elect to stop buying gasoline or buy less fuel for their cars in response to the tax change. Moreover, it is not feasible for everyone who currently drives to work to move closer to their place of employment, schedule carpooling, or arrange to telecommute. For a fairly substantial demographic, gasoline cannot be considered a normal good, as demand for it will not increase if income increases -- unless the increased incomes is truly substantive -- as they quite simply need and purchase fuel in order to get to work and continue employment (Rittenberg, 2009). Some moderate changes can be made by most people to reduce their consumption of gasoline. Regardless, popular opinion holds that the gas taxation is not intended to change consumer behavior, but is instead a device for adding to governmental coffers.

Moffatt (2015) takes these popular arguments into consideration and discusses the price elasticity of the demand for gasoline and summarizes a number of studies to...

While the popular line of thinking suggests that the price elasticity of the demand for gasoline is zero, Moffatt explains why this is not so. Moffatt cites two key meta-analyses that have demonstrated the price elasticity of demand for gasoline (Moffatt, 2015). Following the discussion of the findings from the two meta-analyses, Moffatt concludes that it is not possible to be absolutely confident when predicting the magnitude change on quantity demand for gasoline will be when gas taxes are increased, but it is fair to say that economists and others may certain -- all else being equal -- that when gas taxes rise, consumption of gasoline will decline (Moffatt, 2015).
Espey (1996) reviewed 101 research studies to examine the average price-elasticity over the short-run, which was determined to be one year or less. Her meta-analysis established the price-elasticity demand of gasoline as -0.26. According to Espey's research, if the price of gasoline is increased by 10%, the quantity of demand for gasoline is lowered by 2.6%. Notably, in the long-run, which is considered to be more than one year, the price elasticity of demand is greater at -0.58. That is to say that if the price of gasoline is increased by 10%, the quantity of demand for gasoline will decrease by 5.8% in the long run. To be clear, the quantity demanded…
