Within a financial market where a risk-free bond and a long-lived risky asset are exchanged by investors with heterogeneous trading rules, we assume that the investors most exposed to the risky asset are subject to joint liquidation needs. The latter encompass a risk whenever the market impact...

We examine the impact of risk-based portfolio constraints on asset prices in an exchange economy. Constrained agents scale down their portfolio and behave locally like power utility investors with risk aversion that depends on current market conditions. The imposition of constraints dampens...

We consider a stochastic model of a financial market with one-period assets and endogenous asset prices. The model was initially developed and analyzed in the context of Evolutionary Finance with the main focus on questions of "survival and extinction" of investment strategies (portfolio rules)....

This paper compares two well-known approaches for valuing a risky investment using real options theory:contingent claims (CC) with risk neutral valuation and dynamic programming (DP) using a constant risk adjusted discount rate.Both approaches have been used in valuing forest assets.A proof is...

Purpose - The main purpose of this paper is to investigate the dynamic behavior of a bounded rational monopolist with a general nonlinear demand and quadratic cost functions reflecting diseconomies of scales. Design/methodology/approach - We suppose that locally the monopoly firm uses a gradient...

This paper describes a method for solving a class of forward-looking Markov-switching Rational Expectations models under noisy measurement, by specifying the unobservable expectations component as a general-measurable function of the observable states of the system, to be determined optimally...

We analyze a dynamic Asset Liability Management problem with model uncertainty in a complete market. The fund manager acts in the best interest of the pension holders by maximizing the expected utility derived from the terminal funding ratio. We solve the robust multi-period Asset Liability...
