A model of optimal car replacement is developed and used to examine the impact of alternative policy measures on the optimal car replacement time and on total emissions of pollutants, when environment policy takes the form of: (i) reduced taxes on purchaso of "clean" cars, (ii) administrative...

Policy makers in Europe have become increasingly aware of the need to curb the adverse effects of transport externalities, in particular the impact of cars on the environment. In some countries of the European Union, economic instruments have been used to reduce emissions generated by passenger...

We study insurance and productivity values associated with the Greek Gene Bank (GGB), the largest ex-situ conservation program in Greece. To evaluate the insurance value generated by the holdings of the GGB genetic resources, the current study examined scenarios for alternative arrival...

Nonpoint source (NPS) pollution refers to the form of pollution where neither the source nor the size of specific emissions can be observed and identified with sufficient accuracy. In NPS pollution the ambient concentration of pollutants associated with the individually unobserved emissions is...

Environmental conditions and pollution levels have been proven to affect firms' and households' location decisions in various ways. In this paper, we study the optimal and equilibrium distribution of industrial and residential land in a given region. Industries produce a single good using land...

We introduce knowledge spillovers as an externality in the production function of competitive ��firms operating in a ��nite spatial domain under adjustment costs. Spillovers are spatial as productive knowledge ��flows more easily among firms...

Sustainable development, environmental sustainability, green economies and green growth are issues which are of great importance for both the research and the policy agenda. The present paper clearly defines the concepts of sustainability and environmental sustainability and provides a...

Open Access initiatives, corresponding to unrestricted online access to peer-reviewed scholarly research are developed around the world and supported by research organizations and institutions. European Commission has launched in August 2008 the OpenAIRE (Open Access Infrastructure for Research...

The evolution of renewable resources is characterized in many cases by different time scales where some state variables such as biomass, may evolve relatively faster than other state variables such as carrying capacity. Ignoring this time scale separation means that a slowly changing variable is...

Taking as given that we are consuming too much and that overconsumption leads to environmental degradation, the present paper examines the regulator's choices between informative advertisement and consumptiontaxation. We model overconsumption by considering individuals that care about social...
