The private and public insurance value of conservative biodiversity management

Baumgärtner, Stefan; Quaas, Martin F. - 2006

The ecological literature suggests that biodiversity reduces the variance of ecosystem services. Thus, conservative biodiversity management has an insurance value to risk-averse users of ecosystem services. We analyze a conceptual ecological-economic model in which such management measures...

Optimal dynamic scale and structure of a multi-pollution economy

Baumgärtner, Stefan; Jöst, Frank; Winkler, Ralph - 2007

We analyze the optimal dynamic scale and structure of a two-sectoreconomy, where each sector produces one consumption good and one specific pollutant. Both pollutants accumulate at di_erent rates to stocks which damage the natural environment. This acts as a dynamic driving force for the...

Too much R&D?: vertical differentiation in a model of monopolistic competition

Kranich, Jan - 2007

This paper discusses a model of vertical and horizontal product differentiation within the Dixit-Stiglitz framework of monopolistic competition. Firms compete not only in prices and horizontal attributes of their products, but also in the quality that can be controlled by R&D activities. Based...

Agro-biodiversity as natural insurance and the development of financial insurance markets

Baumgärtner, Stefan; Quaas, Martin F. - 2007

Agro-biodiversity can provide natural insurance to risk averse farmers. We employ a conceptual ecological-economic model to analyze the choice of agrobiodiversity by risk averse farmers who have access to financial insurance. We study the implications for individually and socially optimal...

Managing increasing environmental risks through agro-biodiversity and agri-environmental policies

Baumgärtner, Stefan; Quaas, Martin F. - 2008

Agro-biodiversity can provide natural insurance to risk-averse farmers by reducing the variance of crop yield, and to society at large by reducing the uncertainty in the provision of public-good ecosystem services such as e.g. CO2 storage. We analyze the choice of agro-biodiversity by...

Ecological-economic viability as a criterion of strong sustainability under uncertainty

Baumgärtner, Stefan; Quaas, Martin F. - 2007

Strong sustainability, according to the common definition, requires that different natural and economic capital stocks have to be maintained as physical quantities separately. Yet, in a world of uncertainty this cannot be guaranteed. To therefore define strong sustainability under uncertainty in...

R&D and the agglomeration of industries

Kranich, Jan - 2008

This paper discusses a model of the New Economic Geography, in which the seminal core-periphery model of Krugman (1991) is extended by endogenous research activities. Beyond the common anonymous consideration of R&D expenditures within fixed costs, this model introduces vertical product...
