Using weekly data for the period March 1991 to August 2002, we estimate the response of retail gasoline prices to changes in crude oil and spot gasoline prices in the US allowing for a possibility of two types of cost shocks to the gasoline market: long-term and short-term shocks. Our conclusion...

This paper extends a recent martingale representation result of [N-S] for a Levy process to filtrations generated by a rather large class of semimartingales. As in [N-S], we assume the underlying processes have moments of all orders, but here we allow angle brackets to be stochastic. Following...

A man is a key subject of economics and economic theory. “A man is irrational” - this opinion can be made from Allais paradox, risk aversion and other well-known fundamental problems. For a long time, this opinion was a barrier to proper solution of these problems and the development of the...

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...

Arrangements (agreements, contracts, projects, etc.) are widespread economic events and are the fundamental concept of the economic theory. Infringements (breaches, modifications, changes, etc.) of arrangements are common and have a significant importance for the economic theory. For many years...

We consider the convergence properties of behavior under a comparative negligence rule (CN) and under a rule of negligence with contributory negligence (NCN), assuming bilateral care with three care levels. Using an evolutionary model, we show that CN reduces the proportion of the population...

A revolution in economics. Is it possible? Is its concept a transition from ideal to real economics? The way to the transition may be a new aspect of uncertainty. Problems, which can be solved, research fields, which can be augmented or created, and fields of applications in practical economy...

Environmental economics assumes that reliance on price signals, adjusted for externalities, normally leads to efficient solutions to environmental problems. We explore a limiting case, when market volatility created “mixed signals”: waste paper and other recycled materials were briefly worth...

This paper incorporates informal sector and efficiency wage relation in a Harris-Todaro econmy under differential production structure. The simultaneous existence of the urban informal sector and the urban unemployment has been explained interms of such efficiency wage relation. Two different...
