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

We use a vertical product differentiation model under partial market coverage to study the social welfare optimum and duopoly equilibrium when convex costs of quality provision are either fixed or variable in terms of production. We show that, under fixed costs, at the social welfare optimum...

A three-stage game including investments, environmental quality provision and price competition is developed to study the impact of green technology investment (ecolabeling), in a duopoly model of vertical product differentiation. The firms’ incentives to invest in green technologies depend on...

We study the Baltic Sea countries’ declaration to reduce nutrient loads by 50% in each country in an ecological-economic model. The model consists of country-based abatement cost functions, and transfer coefficients describing how phosphorus and nitrogen flow from one country to another, as...

This paper provides a theoretical framework to study the behavioral and welfare effects of forest conservation, which leads to a binding harvesting constraint for landowners. The economy is modeled as a three-stage game by the interaction of the government’s conservation policy, with...

This paper studies optimal forest policies in an overlapping generations forest economy with one-sided altruism, where timber and monetary bequests can be made across generations and forest amenities are a public good. We extend the existing economics literature by demonstrating that timber...
