The framework presents how trading in the foreign commodity futures and domestic forward foreign exchange markets can affect the optimal spot positions of domestic commodity producers and traders. It generalizes the models of Kawai and Zilcha (1986) and Kofman and Viaene (1991) to allow both...

In this article, we simulate the concentration process within the German dairy sector employing a sector?wide optimization model. As a result, we get cost minimizing structures of the dairy sector for various time horizons depending on varying levels of transportation costs. We show that the...

Many nonmarket valuation models, such as the Ricardian model, have been estimated using cross sectional methods with a single year of data. Although multiple years of data should increase the robustness of such methods, repeated cross sections suggest the results are not stable. We argue that...

The issue of global warming has become a major topic in the international environmental debate. Alternative climate policy measures can be evaluated with the help of a simulation model that integrates economic and natural science considerations. A fully integrated assessment of the two-way...

This paper proposes a new Economic Drought Management Index (EDMI) that could assist water managers to inter-temporally manage water reservoirs. The index's main appeal is that it can be easily interpreted and that it encompasses in a single number hydrological processes, structural constraints,...

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...

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...

In this paper, we investigate the link between intra-household resource allocation and familial ties between household members. We show that, within the same geographic, economic and social environments, households where members have "stronger" familial ties (e.g. a nuclear family household)...

Many nonmarket valuation models, such as the Ricardian model, have been estimated using cross sectional methods with a single year of data. Although multiple years of data should increase the robustness of such methods, repeated cross sections suggest the results are not stable. We argue that...

Since naturally occurring genetic information serves as a valuable input for biotechnological R&D, the private provision of genetic resources could generate income for the protection of biodiversity-rich areas. However, there has been a controversy over whether these potential revenues are...
