This study aimed to investigate the nature of energy applied in hotel industry in Macedonia. It explored the indicators for resources application in three, four and five star hotels. The data were collected by means of an online survey conducted among 45 managers and department supervisors. It...

This paper considers the problem of a water management authority faced with the threat of a drought that hits at an uncertain date. Three management policies are investigated: i) a laissez-faire (open-access) policy of automatic adjustment through a zero marginal private net benefit condition,...

We analyze the role of electricity storage for technological innovations in electricity generation. We propose a directed technological change model of the electricity sector, where innovative firms develop better electricity storage solutions, which affect not only the relative competitiveness...

Predator-prey relationships account for an important part of all interactions between species. In this paper we provide a microfoundation for such predator-prey relations in a food chain. Basic entities of our analysis are representative organisms of species modelled similar to economic...

Economists have a good understanding of intra-economic interdependence and a mature methodology of modeling it. Ecologists focus on the complex and sensitive interactions of species in ecosystems. This paper's objective is to suggest a new micro-foundation of ecosystem analysis based on economic...

This paper presents a simple two-period overlapping generation's model with uncertain lifetimes that contains environmental and health issues. It investigates an intergenerational conflict between old and young generations as regards two defensive expenditures, offsetting the influence of a...

We study the environmental and economic effects of public abatement in the presence of multiple stable steady-state ecological equilibria. Under shallow-lake dynamics (SLD), the isocline for the stock of pollution features two stable branches, a good and a bad one. Assuming that the ecology is...

We incorporate a renewable resource into an overlapping generations model with standard, well-behaved utility and constant returns to scale production functions. Besides being a factor of production the resource serves as a store of value. We characterize dynamics, efficiency and stability of...

Deposit systems for one-way beverage containers are widely supported by green activists and have been implemented in several countries. This paper analyzes whether such deposit systems can optimally internalize the externalities that result when consumers dump these containers. It is shown that...
