Statistical models are usually thought of as means for describing statistical regularities. Concerning stock returns, many empirical regularities have been documented in the literature together with their corresponding models. The main task of this paper is to investigate, under the prism of the...

Wetlands are a crucial component of water resources, providing several ecological functions and services, including flood attenuation, groundwater recharge and water quality maintenance, as well as conservation of biodiversity and provision of recreational activities. In Cyprus, an arid country...

Following Water Framework Directive s (WFD) implementation a national water policy that provides the institutional background to achieve the goals of the suggested policy is required. Chapter 10 emphasises on the issues of water policy that should be addressed and provides reform options that...

The study presented in this chapter, not only presents one of the first applications of the choice experiment method to value benefits from reduction in flood risk in Europe, but also aims to estimate the value of biodiversity, in addition to the local household�s...

We analyze a game with N farmers that extract groundwater from a common aquifer of small storage capacity. Our aim is to compare the socially optimal, myopic and feedback extraction strategies, the latter arising from competitive interaction between extracting agents. Our extension to existing...

Rokua in Northern Finland is a groundwater dependent ecosystem very sensitive to climate change and natural variability. As such, the water level of most of the lakes is a function of the level of the groundwater table of the esker which is naturally recharged. This chapter presents results from...

The Single Factor Model (SFMT) of stock returns in its simplest form, namely the one that assumes time-invariant beta and homoskedastic error has been found to be empirically inadequate.The beta coefficient and the error process exhibit signi��cant time-variation and dynamic...

Air quality affects human�s well being in various ways. Air providing the most important life-support function sustains human health and enables the existence of all ecosystems. Although clean air is considered to be a basic requirement for human health and well-being,...
