The aim of this research is to present and analyse the impact of information asymmetries on the efficient operation of markets. This phenomenon is becoming a new variable that is calling into question the economic development of developing countries. First, we will highlight the problem of asymmetric information by studying the typology of its situations before addressing its impact on economic markets. The second part will be devoted to the microeconomic analysis of its economic and social consequences in order to overcome the difficulties generated by the beekeeping souk. Finally, we will develop an analytical model to determine the effects of informational asymmetry on consumer choice between the different qualities of honey offered by vendors.
