Supply markets: critical literature review

Public markets play a critical role in the social and economic fabric of communities, serving as points of interaction between diverse stakeholders, including merchants, consumers, local authorities and non-profit organizations. This article presents a critical review of the literature on public markets, exploring their dynamics, challenges and impacts on sustainability and economic development. Sellers, as the main stakeholders, ensure the supply of varied products, while consumers seek quality, authenticity and social interaction. Local authorities regulate and promote cultural infrastructure and events, while non-profit organizations encourage ethical and sustainable practices. The complex relationship between these groups is marked by dynamic interactions and, often, conflicts, such as disputes over space, strict regulations and environmental impacts. From an economic point of view, public markets promote the livelihood of small traders, create jobs and boost tourism. They also generate significant revenue by attracting visitors, strengthening the local economy and revitalizing urban areas. However, overtourism can compromise cultural authenticity, drive up prices and put pressure on local residents. Public markets also play a crucial role in sustainability, promoting the sale of local products and practices such as organic farming and waste reduction.
