Affine General Equilibrium Models
نویسنده
چکیده
No-arbitrage models are extremely flexible modelling tools, but often lack economic motivation. This paper describes an equilibrium consumption based CAPM framework based on Epstein-Zin preferences, which produces analytic pricing formulas for stocks and bonds under the assumption that macro growth rates follow affine processes. This allows the construction of equilibrium pricing formulas while maintaining the same flexibility of state dynamics as in no-arbitrage models. In demonstrating the approach, the paper presents a version of the Bansal & Yaron (2004) model which maintains a positive volatility process, as well as an example in which the volatility process is allowed to jump. The latter produces endogenous asset stock market crashes as stock prices drop to reflect a higher expected rate of return in response to increased risk. A third generalization is a model of nominal stock and bond prices. The nominal yield curve in this model has positive slope if expected inflation growth negatively impacts real growth. This model also produces asset prices that are consistent with observed data, including a substantial equity premium at moderate levels of risk aversion. ∗Correspondence: [email protected].

Robust Stackelberg Equilibrium for a Multi-Scenario Two Players Linear Affine-Quadratic Differential Game
This paper presents the formulation of a new concept dealing with a Robust Stackelberg equilibrium for a multi scenario or mutiple models of a linear affine-quadratic game. The game dynamic is given by a family of N different possible differential equations (MultiModel representation) with no information about the trajectory which is realized. The robust Stackelberg strategy for each player mus...
متن کاملIdentifiability of Dynamic Stochastic General Equilibrium Models with Covariance Restrictions
This article is concerned with identification problem of parameters of Dynamic Stochastic General Equilibrium Models with emphasis on structural constraints, so that the number of observable variables is equal to the number of exogenous variables. We derived a set of identifiability conditions and suggested a procedure for a thorough analysis of identification at each point in the parameters sp...
متن کاملRealization of locally extended affine Lie algebras of type $A_1$
Locally extended affine Lie algebras were introduced by Morita and Yoshii in [J. Algebra 301(1) (2006), 59-81] as a natural generalization of extended affine Lie algebras. After that, various generalizations of these Lie algebras have been investigated by others. It is known that a locally extended affine Lie algebra can be recovered from its centerless core, i.e., the ideal generated by weight...

متن کاملA mathematical framework for the control of piecewise-affine models of gene networks
This article introduces results on the control of gene networks, in the context of piecewise-affine models. We propose an extension of this well-documented class of models, where some input variables can affect the main terms of the equations, with a special focus on the case of affine dependence on inputs. Some generic control problems are proposed, which are qualitative, respecting the coarse...
