Gasoline consumption is a significant source of air pollution, a major
environmental concern in urban areas, and an important issue for
transportation policy. Gasoline taxes have been touted by many
economists as an efficient and relatively simple tool to address
environmental concerns and other problems associated with gasoline
consumption. However, rather than removing subsidies and increasing
gasoline taxes, many countries still subsidize gasoline, which may have
the opposite effect of exacerbating the environmental concerns and
other problems associated with gasoline consumption. The prevalence of
gasoline subsidies worldwide and the fall in the global mean gasoline tax
may increase gasoline consumption and exacerbate the air pollution
associated with gasoline consumption. However, whether gasoline
subsidies actually increase air pollution and the effects of gasoline
subsidies on different air pollutants, empirical questions remain open and
are not fully addressed in the previous literature, particularly for oil-rich
countries in the Middle East and North Africa that have the lowest net
taxes.
For this research, the researcher proposes to evaluate the effects of
transportation fuel subsidies on air quality using economic and
econometric modeling. In particular, they will analyze the impact of the
Iranian energy subsidy reform on air quality using a regression
discontinuity design. |
