This paper is a supplement to Ghossoub [11]. In this supplement, some of the results of Ghossoub [11], as well as the techniques used to obtain these result are extended to a more general problem of demand for contingent claims with belief heterogeneity. Moreover, a general problem of monotone...

Traditionally, the Laffer effect has been discussed in context of macroeconomic endogenous growth models or in the situation of labor market whether a tax cut on wages would persuade people to work more and also increase income tax revenues of the government. In this paper, we are firstly...

The practice of applying curve fitting techniques to describe data is widespread in many fields: in biology, in medicine, in engineer, in economy, etc. This paper presents a heuristic technique named Particle Swarm Optimization to be used for parameter estimation in regression models. The...

The classical cobweb theorem is extended to include production lags and price forecasts. Price forecasting based on a longer period has a stabilizing effect on prices. Longer production lags do not necessarily lead to unstable prices; very long lags lead to cycles of constant amplitude. The...

The article analyses an approach to construction of the mathematical model for the commercial banking industry based upon set theory, abstract algebra, and computational linguistics.

We develop a general method to solve models of interactions between multiple agents, including the possibility of strategic advantage for some of them. We argue that this type of model applies to the description of apparently irrational or biased behaviors in a person whose action is the...

The successful active portfolio manager has to have at least two main competencies: Felicitous asset allocation choice and the competence to do so at the right point in time. Based on an extension of Grinold and Kahn’s Fundamental Law of Active Management, this paper describes a method to...

In the classical theory of monotone equimeasurable rearrangements of functions, “equimeasurability” (i.e. the fact the two functions have the same distribution) is defined relative to a given additive probability measure. These rearrangement tools have been successfully used in many problems...

The article analyses an approach to construction of the mathematical model for the bank based upon set theory and abstract algebra. It is shown that selection of correspond algebraic structure for simulation is influence directly on basis of methods for solving engineering and economical...
