This paper offers a new perspective on the issue of urban sustainability. Starting from a positive perspective on city life, it makes a typology of critical roles of the city that are to be considered with a view to urban sustainability. Next, it is argued that a sine qua non for a structured...

Biodiversity has received much attention in environmental research and public policy in recent years. There is a world-wide interest in its relevance for the carrying capacity of rich but fragile ecosystems. Voices suggesting building up proper protection mechanisms for unique and scarce...

In this paper the concept of total economic value of an environmental asset is introduced. The different valuation methods, putting a monetary value on environmental resources as a nonmarket good are also reviewed. Particular emphasis is placed on policy-making and the link of contingent...

We use a dynamic model to study the effects of technology and learning on the long run economic growth rates of a leading and a lagging region. New technologies are developed in the leading region but technological improvements in the lagging region are the result of learning from the leading...

We study innovation and the resulting Schumpeterian economic growth that this innovation gives rise to in a model with N heterogeneous regions. For each region i where i=1,...,N, our analysis leads to five findings. First, we define the balanced growth path (BGP) allocations and the equilibrium...
