Retail is undergoing an unprecedented transition. The internet has led to new sales channels and new opportunities to reach out to customers, and globalization has opened markets and introduced new competitors. Sustainability has moved up the agenda for retail players. All companies in the retail sector and the business world in general, are changing their philosophy and way of doing business to be more sustainable. Because for consumers it not only matters that brands do well, they want them to give the best of themselves and not only worry about economic aspects, but also monitor their social and environmental impact. However, is sustainability possible in the retail sector in Poland?

The Brazilian Fuel Market is characterized by having three main fuel types in form of gasoline, ethanol and diesel, with distinct and relevant consumer market. This study aims to investigate in what way gas stations deal with cost shocks to the price they pay to the distributors – if they pass on these price shocks in the same way when they are positive or negative. This was done by applying a cointegration approach, by using an Error Correction Model (ECM) as proposed by Engle and Granger, adapted to allow asymmetric behavior. The model was applied at gas station level, using data from 05/11/2004 to 12/31/2019. The results reinforce previous study conclusions – both in sense that asymmetry should be studied at firm level and in a way that gas stations practice different price strategies for each one of the fuels they sell. Finally, this study tries to relate the results with some of the causes appointed to asymmetric behavior, trying to open new paths for further investigation.

Retail trade has undergone many transformations over the years. How we perceive it today is influenced by many factors, often related to new technologies. Recently, the transformation of trade is also increasingly influenced by the willingness to adapt to the assumptions of sustainable development. These assumptions cover many aspects of socio-economic life. The paper is an attempt to evaluate the current transformations in retail trade and to estimate its future changes.
