Cover Story: During the COVID-19 pandemic, the economy was strongly affected by the restrictions imposed by the authorities to prevent the spread of the virus, and local online platforms and e-commerce experienced an accelerated rate of growth. The purpose of this study is to highlight the determinants of consumer behavior on local online market platforms, as well as the barriers that affect the intention to shop online. By conducting a qualitative survey and applying a probit binary choice model, the analysis was centered on several variables with expected important impact on quick and flexible response/adaptation to new market profiles, such as the age of the respondents, the level of income, the trend of online purchasing of different categories of goods, and the propensity towards online payment.
