On the basis of mathematical similarity, we will try to interpret microeconomics by using the physics. Simply, the CobWeb market, the simplest, standard microeconomic market model, will be related to the photon dynamics in a thermal optical cavity. In the market, we have two different time concepts; the physical time of the physical world and the market time in market information space. We also clarify confusingly-used time setting conditions: Markov, Stratonovich, and Wiener. Thus, the standard CobWeb model takes market time under the Wiener condition only. The price corresponds to the average energy of the photons, and the demand-supply curve in the market corresponds to the energy exchange equation. We expect further interpretations of microeconomics to be possible by using physics.
