Abstract

We propose an asset pricing model with heterogeneous agents, asynchronous updating of beliefs, a market maker, and a firm that issues or buys back its own shares to exploit mispricing. The deterministic skeleton of the model is a two-dimensional piecewise-smooth map. We present an analytical study of the fundamental equilibrium and the coexisting non-fundamental equilibria. In comparison to Hommes et al. (2005), the firm's trading helps to dampen the extreme price realizations in the chaotic region of the model. The trading activities benefit the firm, generating growth in its value over time. The same firm engagement in a Walrasian market can exacerbate the price dynamics.
