Agricultural productivity in Sudan is historically known to be low, particularly in the traditional sector. Trueblood and Coggins (2001) stated that, Sudan's decrease in agricultural productivity during the period (1961-1991) was due to decreases in both efficiency and technology adoption....

It is a stylized fact of formal mathematical modeling that a 'space' cannot be described by attempts at parameterization of distances or areas (under or above curves) that feasibly could occur within the space. Tools for parameterization of mathematical spaces, such as Set Theory, Connectedness,...

This research note provides clear, unambiguous rationalization for the normative that applications of utility functions to modeling of expectations are non-robust, are, in relation to best practice, out of whack. With this inference in tow, all formal theoretical studies that apply utility...

This paper analyzes the problem of a benevolent planner wishing to control a population of heterogeneous agents subject to idiosyncratic shocks. This is equivalent to a deterministic control problem in which the state variable is the cross-sectional distribution. We show how, in continuous time,...

Under the background of the electronic security trading platform Xetra operated by Frankfurt Stock Exchange, we consider the Xetra auction market system (XAMS) from 'bottom-up', which the interaction among heterogeneous traders and Xetra auction market mechanism generates non-equilibrium price...

This paper introduces a dynamical extension to the theoretical framework proposed by Slim (2009), where the author analyzes price formation in illegal markets. We develop a simple model with two regimes that can show a rich variety of dynamic behaviors, such as cyclical or even chaotic...

The economy is heterogeneous, complex, dynamic, interdependent and interactive. This new market paradigm developed for analyzing economic behaviors gives a holistic analysis of the system by employing the Behavioral Systems Approach, Cobweb Theorem and Evolutionary Game Theory in obtaining the...

In this paper we present a recursive method for the numerical simulation of nonoptimal dynamic equilibrium models. This method builds upon a convergent operator over an expanded set of state variables. The fixed point of this operator defines the set of all Markovian equilibria. We study...

This paper presents a detailed 2019 Social Accounting Matrix (SAM) for Benin as a basis for policy analysis with a focus on agriculture, food processing and energy generation from byproducts. It is based on official statistics collected from national and international institutions (national...

The highly mathematical nature of the Arrow-Debreu and other similar models of general equilibrium hide rather than elucidate the nature of equilibrium in a private property market economy where all factors of production may be purchased or rented. It is an empirical commonplace that the...
