Watching Corn Grow: A Hedonic Study of the Iowa Landscape AgEcon
Secchi, Silvia.
Landscape amenities can be scarce in places with large areas of open space. Intensely farmed areas with high levels of monocropping and livestock production are akin to developed open space areas and do not provide many services in terms of landscape amenities. Open space in the form of farmland is plentiful, but parks and their services are in short supply. This issue is of particular importance for public policy because it is closely linked to the impact of externalities caused by agricultural activities and to the indirect effects of land use dynamics. This study looks at the impact of landscape amenities on rural residential property values in five counties in North Central Iowa using a hedonic pricing model based on geographic information systems. The...

THE EXTENT OF SPRAWL IN THE FRINGE OF JAKARTA METROPOLITAN AREA FROM THE PERSPECTIVE OF EXTERNALITIES AgEcon
Fitriani, Rahma; Harris, Michael.
The Jakarta Metropolitan area has experienced urban sprawl. Existing planning processes do not appear to manage sprawl effectively. The aim of this study is to empirically analyse the contribution of spatial externalities on sprawl, and its effect on proximate agricultural land and conservation areas. A residential location choice model incorporating externalities is constructed, and a Tobit panel data analysis is conducted using grid-based land use data. The analysis finds significant empirical evidence regarding the contribution of neighbourhood development externalities to sprawl. Implications for policy are discussed.

Selective vs. Broad-Spectrum Pesticides: When Do Private Decisions Differ from Socially Optimal Decisions? AgEcon
Grogan, Kelly A.; Goodhue, Rachael E..
This paper examines the spatial externalities of conventional and organic pest control methods to determine if, and how, the two types affect each other. These interactions make the problem more complicated than the usual analysis of a single externality. The numerical simulation model includes one organically managed and one conventionally managed field. One pest and one predator of the pest move between the two fields over five seasons. In each season, the conventional grower has the option of applying a broad-spectrum pesticide that kills the predator a selective pesticide that has no adverse effects on the predator but is either more expensive or less effective than the broad-spectrum pesticide. The organic grower can apply an organic pesticide,...

Spatial Externalities of Pest Control Decisions in the California Citrus Industry AgEcon
Grogan, Kelly A.; Goodhue, Rachael E..
Predaceous and parasitic insects provide control of important citrus pests. However, many pesticides are toxic to these beneficials. Using California citrus grower survey data, this article tests whether landscape-level use of pesticides affects the presence of and reliance on Aphytis melinus, an important beneficial insect. Results show that landscape-level pesticide use decreases the presence of A. melinus and increases reliance on insecticides. Pesticide use on non-citrus crops has a significant negative effect on the presence of Aphytis melinus, suggesting a cross-crop spatial externality. Our findings illustrate that regulations designed to address cross-crop effects on beneficial insects can increase social welfare.

Buying Ecological Services: Nature’s Harmonies, Fragmented Reserves and the Agricultural Extensification Debate AgEcon
Hennessy, David A.; Lapan, Harvey E..
Growing demand for cropland products has placed intense pressure on the ability of land resources to support nature, straining public budgets to purchase environmental goods. Fixing overall agricultural output, two policy options are whether to promote more extensive and nature friendly farming practices or to produce intensively on some land and leave the rest wild. Microeconomic models of the topic have not accommodated widely recognized complementary spatial externalities in providing ecological services. This article does so, identifying also a third policy possibility. This is that environmental services can follow a smoothly varying spatial path characterized by harmonic functions.
