A new alternative diffusion model for asset price movements is presented. In contrast to the popular approach of Brownian motion it proposes deterministic diffusion for the modelling of stock price movements. These diffusion processes are a new area of physical research and can be created by the...

We study a class of endowment economies with long-run risks in which agents have generalized recursive smooth ambiguity preferences and heterogeneous beliefs. The expected growth rate of aggregate consumption consists of a persistent component. Agents cannot observe the component but learn about...

We propose an extension of the class of rational expectations bubbles (REBs) to the more general rational beliefs setting of Kurz (1994a,b). In a potentially non-stationary but stationarizable environment, among an heterogenous population of agents, it is possible to hold more than one...

We study the problem of pricing contingent claims in the presence of uncertainty about the timing and the size of a jump in the price of the underlying. We characterize the price of the claim as the minimal solution of a constrained BSDE and derive a pricing PDE in the special case of a...

We develop a theory of equilibrium market instability in a general equilibrium duopoly caused merely by strategic trade. An economy is described as a strategic market game, where players have market power as buyers and sellers. First order conditions of individual decisions are the first kind...

This paper addresses the long-standing question of whether asset prices are predictable. The common view holds that daily prices fully incorporate all available information, and therefore price changes are unforecastable. This conclusion does not necessarily hold when the vast bulk of market...

We generalize the long-run risks (LRR) model in Bansal and Yaron (2004) by incorporating the recursive smooth ambiguity aversion preferences of Klibanoff, Marinacci, and Mukerji (2005, 2009) and time-varying ambiguity. Relative to the Bansal-Yaron model, the generalized LRR model remains...
