A 2017 comparative study of traditional wet markets and supermarkets in urban Accra found that there was no significant conflict between the two categories of markets since the influx of new supermarkets in Ghana led by Melcom began in the 1990s, but anticipated future tension between the two without government policies to improve the infrastructure and food safety of wet markets. The study found that consumers at the supermarkets came from the same socio-economic and geographical backgrounds but with higher educational backgrounds than those at the traditional wet markets.
