The dynamic auction under the protective equipment on COVID-19 has become crucial since the outbreak in December 2019. In this study, we focus on how to remove the shortage of protective equipment of COVID-19 such as face masks, gloves, gowns, goggles, and other equipment used for the protection of the spread of the virus. The dynamic auction market meets many challenges of excess demand, so in this dynamic auction, we propose an extraction auction mechanism to achieve an optimal equilibrium. This equilibrium outcome is competitive equilibrium from the bidder’s true valuation.
