Most prices and interest rates display fluctuating levels that embody extractable energy and equivalent amounts of money. Such fluctuations are also associated with varying degrees of uncertainty. Shannon's derivations of spectral entropy and information content offer computational techniques...

The illicit dealing in gemstones (including diamonds) is a fast growing activity in African countries which produce these minerals. Zaire and Angola are two extreme examples, but by no means exceptions. The preferred policy efforts to controlling the flow of illicit trade in gems have been...

A pure exchange economy with a financial market is studied where aggregate dividends are modeled as a diffusion. The dynamics of the diffusion are allowed to depend on factors which are unobservable to the agents and have to be estimated. With perfect information, the asset market would be...

The paper measures economic loss from the problem of inadequate collateral in Bulgaria and proposes solutions consisting of creation of security interests, perfection, and enforcement.

We analyze markets in which the price of a traded commodity is such that the supply and the demand are unequal. Under standard assumptions, the agents then have single peaked preferences on their consumption or production choices. For such markets, we propose a class of Uniform Trade rules each...

This paper surveys both the theoretical and empirical economics literatures on nonlinearity, complex dynamics, and chaos. Unlike earlier survey papers, this one is written for professional researchers in the area and assumes relevant mathematical background. Unsolved problems and unresolved...

Combining and Extending the concepts of fluid viscosity, system dynamics and Cobb-Douglas production function, an attempt was made to propose a theoretical framework that models the effect of organizational structure on organizational self-renewal and knowledge diffusion. It was showed that...

We work out technical efficiency levels of 29 countries consisting of some selected South Asian, East Asian and EU countries using data envelopment analysis. Luxembourg has an efficiency score of one(most efficient) in all the years .Netherlands also has an efficiency score of one in...

The objective of this paper is to re-examine the impact of universal education policy on the incidence of child labour and on the adult unemployment in a job-search model. The paper assumes the double role played by the universal education programme. It raises the number of school going children...

We consider sets defined by the usual stochastic ordering relation and by the second order stochastic dominance relation. Under fairy general assumptions we prove that in the space of integrable random variables the closed convex hull of the first set is equal to the second set.
