Households in low-income areas face significantly higher increases in petrol prices when rival fuel stations close compared to high-income areas, according to new research led by the University of East Anglia (UEA).   At the same time, low-income areas do not benefit from a higher drop in prices when new stations open.   The study is published today in the Journal of Industrial Economics. It shows that it matters who operates the petrol stations: large chains respond with higher price increases following the exit of one of their rivals.   Other factors, such as reliance on cars, commuting distance, age, or education also drive some of this ...
