In the Eulerian approach the behavior of the atmospheric pollutants is described relative to a fixed coordinate system. Thus the pollutant concentration is a function depending on the system coordinates and must satisfy the material balance taken over a volume element. Expressed mathematically,...

In the current document we are referring to the existing data concerning the impact that benzene - which is one of the most important components of different types of fuels - has on Bucharest and on its inhabitants. We are also trying to present possible solutions to this serious problem which...

In the Lagrangian approach to the turbulent diffusion the species concentrations are described relative to the moving fluid. This approach is concerned with the behavior of the fluid particle existing in a carrying turbulent fluid. Lagrangian theory describes the statistics of the pollutant...

The Czech Republic has introduced new energy taxation in connection with implementation of the directive 2003/96/EC, restructuring the Community framework for the taxation of energy products and electricity. New energy taxes are imposed on electricity, solid fuels and natural gas, with term of...

New tax rules with effect from 1 May 2009 with a series of changes on the tax deductibility of the value added acquisitions related to transport and fuel use. The measure is very obvious nature of politics in order to bring the state budget amounts as required under the current government crisis...

The European Commission is going to discuss a revision of Directive 2003/96/ EC, restructuring the Community framework for the taxation of energy products and electricity. The first proposals include a new energy taxation system, where the current energy tax is divided into two components - an...

This paper reports results of the research concerning incidence of the value added tax in the Czech Republic over the period 1993-2004. The aim of our research was to analyse the impact of the harmonisation of the VAT rates connected with the entry of the Czech Republic into the EU on the...

This paper analyzes the tax penalty on volatile personal income under progressive tax rates. The phenomenon may have an effect on long-term entrepreneurial decisions as well as risky occupational choice. An options-based model is used to estimate the expected effective rate due from tax-payers...

The paper focuses on selective investment incentives, which are aimed primarily to attract foreign direct investment, in the context of the new EU Member States, namely the Czech Republic, Hungary, Poland and Slovakia. We discuss the issue within three closely related dimensions. We point to a...

This paper is focused on the theory of optimal taxation applied to environmental regulation. The first part summarizes the current state of knowledge in this field, especially it concentrates on the so called double dividend hypothesis. The second part of the paper defines the concept of triple...
