Utility functions that are additively-separable in goods consumption and leisure are often used in dynamic stochastic general equilibrium (DSGE) models. This paper illustrates how the use of an elliptical functional form for the utility of leisure can be substituted for the more common constant...

The Conflict Analysis approach by Hipel and Fraser (1984) is well equipped to model repeated games. Players are assumed to posses a sequential reasoning that allows them to (not necessarily correctly) anticipate the reaction of other players to their strategies. An individual’s best response...

We propose a general approach to study the differential effects of exogenous shocks in economic models with heterogeneous agents. Our setting applies to models that can be stated as ``competition for market shares'' in a broad sense. Examples that fit our type of structure are ubiquitous in...

There are three types of "Anything Goes" results: two of them from economic theory and one from the realms of dynamical systems. The study considers the implications of such results and tries to identify conditions under which certain types of conclusions may be implied: convergence, cycles or...

This paper presents a tractable model of non-linear dynamics of market returns using a Langevin approach.Due to non-linearity of an interaction potential, the model admits regimes of both small and large return fluctuations. Langevin dynamics are mapped onto an equivalent quantum mechanical (QM)...

In this note, departing from the traditional static and fully rational economic agent setting, I study a dynamic model of a boundedly rational monopolist who, in a partially known environment, follows a rule of thumb learning process. Instead of considering the classical differential model with...

In this paper we study a class of infinite horizon fully coupled forward-backward stochastic differential equations (FBSDEs), that are stimulated by various continuous time future expectations models with random coefficients. Under standard Lipschitz and monotonicity conditions, and by means of...

Competition between oligopolist electricity generators is inhibited by transmission constraints. I present a supply function equilibrium (SFE) model of an electricity market with a single lossless, but constrained, transmission line. The market admits equilibria in which generator withhold...

The proliferation of algorithmic high-frequency trading in financial markets has also led to an increase in new types of fraudulent activity. Since the flash-crash of 2010 first brought it to popular prominence, layering or spoofing fraud has become a major concern for financial regulators...

This paper provides the proofs to the analysis of a continuous time matching model with saving in Bayer and Wälde (2010a). The paper proves the results on consumption growth, provides an existence proof for optimal consumption and a detailed derivation of the Fokker-Planck equations
