Testing monetary exchange rate models with the Westerlund panel cointegration test
172-179Views:79Time series testing of long-run monetary models of exchange rate determination in most cases fails to support the conjectures of the theory. The empirical literature increasingly uses the panel technique when testing monetary exchange rate models because the power of the panel unit root and panel cointegration tests seems higher than the pure time series tests. In this paper we examine the validity of the monetary exchange rate models over the period 1996Q1-2011Q4 for US dollar exchange rates of 15 OECD countries using Westerlund’s 2007 panel cointegration tests. We found moderate empirical support for monetary exchange rate models.

The significane of environmental taxes used for mitigating the environment harmful impacts of road transportation
47-53Views:115Logistics is one of the most important economic sectors of the European Union, with nearly 1.134 million companies engaged in the field of transportation in the EU. The global logistics market is expected to show further expansion in the forthcoming years. On the other side stands global warning which is one of the greatest problems for the time being. The European Commission has announced a cross-sectoral investment programme worth more than 10 billion euros (nearly 3,200 billion Hungarian forints) for the planning, development and implementation of low carbon dioxide-emitting technologies to improve Europe’s global competitiveness. The common data base of OECD and the European Environment Agency (EEA) currently lists 375 environmental taxes and approximately 250 environmental fees or charges in the OECD countries. Among the EU member states, Sweden, for example, introduced a tax system which includes the essential elements of eco-tax more than 10 years ago. Hungary has several of such tax types, such as the excise tax on fuel, the energy tax, the energy suppliers’ income tax or the vehicle tax.
