In this paper we discuss the determinants which contribute to outbound tourism expenditures. The aim is to show whether and how different socio-economic factors in countries of origin are responsible for the demand, to spent money for tourist activities in foreign countries. While we are able to...

In this paper we discuss the effects of cultural and particular religious factors on tourist flows into the USA as the world largest tourism destination. To estimate this empirically we run an augmented gravity equation. Our results give evidence that the gravity equation is an adequate...

During the last years, the renewable energy strategy of the European Union (EU) and the proposed policies and regulations, namely the Renewable Energy Directive (RED), have been heavily discussed among scientific circles and various interest groups. The sustainability of different biofuels and...

The European Union´s (EU) Renewable Energy Directive (RED) continues to be the focus of much debate over the validity of biofuel sustainability. The debate is driven in part by ongoing concerns of transparency and regional variations of emissions from feedstock cultivation and processing. In a...

We analyze whether biodiversity is increasing the receipts of tourism and beneficial for Least Developed Countries (LDCs). The underlying assumption is that a rich biodiversity provides a comparative advantage for most LDCs. We use a simple trade theory framework. The model is supported by an...

The environmental discussion is increasingly extended to the question of how to preserve biodiversity. As sensible regulation of biodiversity utilization uses politically set incentive schemes, it is required to discus the monetary value of biodiversity. Consequently, the relation between...
