the pest control decisions of a grower who optimally utilizes a pesticide and a predaceous insect to control the crop pest … decisions involve entirely mitigating the negative effects of the pesticide as well as releasing additional predators. …

Applying the Environmental Kuznets Curve hypothesis, the economic structure of pesticide consumption in the world was … significantly affects the pesticide consumption. Additionally, sustained population per land is also influential. In spite of the … applicability of the hypothesis, it was also demonstrated that the great increase of pesticide consumption in developing countries …

). However, studies that have analyzed the value of groundwater in irrigation have found mixed results. Hartman and Taylor (1989 …) and Sunderland, Libbin and Torell (1987) find that groundwater irrigation has no significant effect on land prices …; Torrell et al. (1990) find a significant positive effect of groundwater in irrigation. One explanation is that in areas where …

A key feature of hydrologically connected surface and groundwater stocks is the two-way exchange of water between the … groundwater systems when economic agents withdraw water from both for use in production. I use the model to describe optimal water … extraction from both stocks and to evaluate how a conjunctive management policy shifts welfare between surface and groundwater …

Developing groundwater management plans requires a good understanding of the interdependence of groundwater hydrology … and producer water use behavior. While state-of-the-art groundwater models require water demand data at highly …
