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...

This paper casts doubt on empirical results based on panel estimations of an “inverted-U” relationship between per capita GDP and pollution. Using a new data set for OECD countries on carbon dioxide emissions for the period 1960-1997, we find that the crucial assumption of homogeneity across...

In this project we will analyse specific economic factors of O.U.T.A. (Organism of Urban and Transportations of Athens. O.U.T.A. is a legal person of private law and was established in according to the law 2175/1993, as a successor of O.U.T. . (Organism of Urban and Transportations). O.U.T.A....

The identification is made of those conditions by which it is possible to generate synergy or mutually enforcing relations between economic development and environment conservation with the perspective of a systems entropy flow limits. Monetary and fiscal policies are the framework of structural...

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...

We consider a small open Harris-Todaro (1970) economy complementing global exposure, informal labour training and the urban unemployment. Workers acquire skills through apprenticeship training in the urban informal sector. The informal employers are motivated to train the apprentices by the...

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...
