The existence of vector functions of equilibrium prices in market models described by differential equations is studied. In the models under study, supply and demand depend not only on the commodity prices but also on the price change rate. Sufficient conditions for the existence of equilibrium in such models are obtained as corollaries of theorems on the existence of coincidence points for mappings acting from a q0-symmetric (q1, q2)-quasimetric price space into the metric space of purchased sets of goods.
