Given an excess demand function of an economy, say Z(p), a stable price adjustment mechanism (SPAM) guarantees convergence of solution path p(t,p0) to an equilibrium peq solution of Z(p)=0. Besides, all equilibrium points of Z(p) are asymptotically stable. Some SPAMs have been proposed,...

Markets have internal dynamics leading to stilized facts, such as fat-tails in price fluctuations and long-run memory. In this paper, we use a nonequilibrium price formation rule to explore feedback effects in trading strategies and market dynamics. By interpreting trading strategies as a...
