BANDWIDTH SELECTION FOR SPATIAL HAC AND OTHER ROBUST COVARIANCE ESTIMATORS AgEcon
Lambert, Dayton M.; Florax, Raymond J.G.M.; Cho, Seong-Hoon.
This research note documents estimation procedures and results for an empirical investigation of the performance of the recently developed spatial, heteroskedasticity and autocorrelation consistent (HAC) covariance estimator calibrated with different kernel bandwidths. The empirical example is concerned with a hedonic price model for residential property values. The first bandwidth approach varies an a priori determined plug-in bandwidth criterion. The second method is a data driven cross-validation approach to determine the optimal neighborhood. The third approach uses a robust semivariogram to determine the range over which residuals are spatially correlated. Inference becomes more conservative as the plug-in bandwidth is increased. The data-driven...

The Impact of an Urban Growth Boundary on Land Development in Knox County, Tennessee: A Comparison of Two-Stage Probit Least Squares and Multilayer Neural Network Models AgEcon
Cho, Seong-Hoon; Omitaomu, Olufemi A.; Poudyal, Neelam C.; Eastwood, David B..
The impact of an urban growth boundary (UGB) on land development in Knox County, TN is estimated via two-stage probit and neural-network models. The insignificance of UGB variable in the two-stage probit model and more visible development patterns in the western part of Knoxville and the neighboring town of Farragut during the post-UGB period in both models suggest that the UGB has not curtailed urban sprawl. Although the network model is found to be a viable alternative to more conventional discrete choice approach for improving the predictability of land development, it is at the cost of evaluating marginal effects.

Measuring the Contribution of Water and Green Space Amenities to Housing Values: An Application and Comparison of Spatially Weighted Hedonic Models AgEcon
Cho, Seong-Hoon; Bowker, James Michael; Park, William M..
This study estimates the influence of proximity to water bodies and park amenities on residential housing values in Knox County, Tennessee, using the hedonic price approach. Values for proximity to water bodies and parks are first estimated globally with a standard ordinary least squares (OLS) model. A locally weighted regression model is then employed to investigate spatial nonstationarity and generate local estimates for individual sources of each amenity. The local model reveals some important local differences in the effects of proximity to water bodies and parks on housing price.

COMMUNITY CHOICES AND HOUSING DECISIONS: A SPATIAL ANALYSIS OF THE SOUTHERN APPALACHIAN HIGHLANDS AgEcon
Cho, Seong-Hoon; Newman, David H.; Wear, David N..
This paper examines land development using an integrated approach that combines residential decisions about choices of community in the Southern Appalachian region with the application of the GIS (Geographical Information System). The empirical model infers a distinctive heterogeneity in the characteristics of community choices. The results also indicate that socioeconomic motives strongly affect urban housing decisions while environmental amenities affect those of rural housing.

Spatial Analysis of Rural Economic Development Using a Locally Weighted Regression Model AgEcon
Cho, Seong-Hoon; Kim, Seung Gyu; Clark, Christopher D.; Park, William M..
This study uses locally weighted regression to identify county-level characteristics that serve as drivers of creative employment throughout the southern United States. We found that higher per capita income, greater infrastructure investments, and the rural nature of a county tended to promote creative employment density, while higher scores on a natural amenity index had the opposite effect. We were also able to identify and map clusters of rural counties where the marginal effects of these variables on creative employment density were greatest. These findings should help rural communities to promote creative employment growth as a means of furthering rural economic development.

Amenity Value of Urban Forest Landscapes Attributed to Houses within a 10-Minute Driving Distance AgEcon
Kim, Seung Gyu; Cho, Seong-Hoon; Roberts, Roland K.; Claassen, Roger.
The main objective of this research is to propose a data-driven approach to estimate the amenity values of restoring urban forest landscapes at potential target sites. The approach allows establishing the overall price-driving time relationship between the amenity values attributable to both deforested and forested areas and their proximities to housing locations within a given community. Establishing the overall price-driving time relationship is important because the hedonic price model cannot be used to estimate the amenity values of yet to be restored urban forest landscapes that do not exist at the time of housing sales transactions. We estimated the sum of the differences between amenity values of deforested and forested areas on housing prices...

Public Expenditure and Poverty Reduction in the Southern United States AgEcon
Jung, Suhyun; Cho, Seong-Hoon; Roberts, Roland K..
The objective of this research was to analyze the effects of education, health and hospital, parks and recreation, and public welfare expenditures on poverty, focusing particularly on how these relationships change over space and time. Government expenditure on parks and recreation has been the single most effective government expenditure category over time, although the marginal effects of the government expenditure on poverty alleviation have weakened over time. Clusters of the highest marginal effects of government expenditures on poverty reduction were identified for each time period using geographically weighted regression (GWR) and analysis of local indicators of spatial association (LISA)

MEASURING INTERACTIONS AMONG URBAN DEVELOPMENT, LAND USE REGULATIONS, AND PUBLIC FINANCE AgEcon
Cho, Seong-Hoon; Wu, JunJie.
In this paper, a theoretical model is developed to analyze the interactions among residential development, land use regulations, and public financial impacts (public expenditure and property tax). A simultaneous equations system with self-selection and discrete dependent variables is estimated to determine the interactions for counties in the five western states (California, Idaho, Nevada, Oregon, and Washington). The results show that county governments are more likely to impose land use regulations when facing rapid land development, high public expenditure and property tax. The land use regulations, in turn, decrease land development, long-run public expenditure, and property tax at the cost of higher housing prices and property tax. During the...

Negative Externalities on Property Values Resulting from Water Impairment: The Case of the Pigeon River Watershed AgEcon
Cho, Seong-Hoon; Roberts, Roland K.; Kim, Seung Gyu.
The following hypothesis was tested: Willingness to bear a negative water impairment externality differs between those who do and those who do not receive economic benefit from the impairment source, e.g., a paper mill. The hypothesis was tested using a hedonic analysis of ambient water quality in two discrete housing markets in the Pigeon River Watershed, which have been polluted by the operation of a paper mill. The results suggest that North Carolina residents of the subwatersheds with impaired river, who experience economic benefits from the paper mill in addition to harmful effects, do perceive the pollution as a negative externality, whereas they may have a willingness to bear a similar type of negative externality associated with impaired streams....

Projecting Spatial Pattern of Housing Growth in Tennessee AgEcon
Cho, Seong-Hoon; Clark, Christopher D.; Park, William M..
Housing growth in Tennessee that incorporates spatial spillover and spatial heterogeneity at the level of census-block group is projected. A deterministic interpolation technique is adopted to create alternative neighborhood variables that captures spatial spillover of neighborhood effects on housing growth without multicollinearity. The maps drawn using the geographically weighted regression parameter estimates revealed that the local marginal effect of the housing price increases on housing growth gradually increases as one moves eastward. The population growth in the adjacent neighborhood-block group has about 10% of marginal effect of population growth in its own block group. The marginal effect of population growth is relatively higher in the...

Extreme coefficients in Geographically Weighted Regression and their effects on mapping AgEcon
Cho, Seong-Hoon; Lambert, Dayton M.; Kim, Seung Gyu; Jung, Suhyun.
This study deals with the issue of extreme coefficients in geographically weighted regression (GWR) and their effects on mapping coefficients using three datasets with different spatial resolutions. We found that although GWR yields extreme coefficients regardless of the resolution of the dataset or types of kernel function, 1) the GWR tends to generate extreme coefficients for less spatially dense datasets, 2) coefficient maps based on polygon data representing aggregated areal units are more sensitive to extreme coefficients, and 3) coefficient maps using bandwidths generated by a fixed calibration procedure are more vulnerable to the extreme coefficients than adaptive calibration.

Effects of Forestland Ownership Conversion on Greenhouse Gas Emissions: The Case of South Korea AgEcon
Cho, Seong-Hoon; Kim, Hee Ho; Roberts, Roland K.; Kim, Seung Gyu; Lee, Daegoon.
This research analyzed the effects of forestland conversion from private to public ownership on greenhouse gas emissions by quantifying the relationship between forestland ownership conversion and deforestation, and then examining the effects of the change in deforestation on greenhouse gas emissions in South Korea. Ex ante simulations forecast greenhouse gas emissions resulting from deforestation rates under the current level of national forestland and three scenarios of increased percentages of national forestland. The findings suggest that increasing the percentage of national forestland would mitigate the increase in the deforestation rate, which in turn would moderate the increase in greenhouse gas emissions.

Two Dimensions of the Spatial Distribution of Housing: Dependency and Heterogeneity across Tennessee’s Six Metropolitan Statistical Areas AgEcon
Cho, Seong-Hoon; Clark, Christopher D.; Park, William M..
A two-stage multinomial logit selection model is used to model the relationship between demographic characteristics and housing density across Tennessee’s six metropolitan statistical areas. The study finds that there is both spatial correlation and heterogeneity in the most densely populated area, has the least amount of spatial correlation among housing density at the neighborhood level, while Johnson City, which has the lowest overall housing density, has the highest degree of spatial correlation.

Modeling Willingness to Pay for Land Conservation Easements: Treatment of Zero and Protest Bids and Application and Policy Implications AgEcon
Cho, Seong-Hoon; Yen, Steven T.; Bowker, James Michael; Newman, David H..
This study compares an ordered probit model and a Tobit model with selection to take into account both true zero and protest zero bids while estimating the willingness to pay (WTP) for conservation easements in Macon County, NC. By comparing the two models, the ordered/unordered selection issue of the protest responses is analyzed to demonstrate how the treatment of protest responses can significantly influence WTP models. Both models consistently show that income and knowledge are positive and significant factors, while distance to poorer quality streams and duration of residency are negative and significant factors on WTP.

Ridge, Slope, and Hillside Protection Taskforce Projects in Knox County, Tennessee: Costs and Benefits of Reforestation of Target Areas AgEcon
Chadourne, Matthew H.; Cho, Seong-Hoon; Roberts, Roland K..
Many communities in the United States face the decision about whether to protect or restore forests on environmentally sensitive sites. The objective of this research is to identify priority areas for forest landscape restoration in Knox County, Tennessee. A cost-benefit analysis is conducted to determine individuals’ willingness to accept reforestation as a substitute for other potential land uses, given the explicit costs and benefits of reforestation. A sequence of hedonic models is used to estimate differences in values attached to housing prices of multiple potential sites for restoration projects values. This approach allows the establishment of an overall price-distance relationship between the amenity values attributable to both deforested and...

Measuring the Contribution of Water and Green Space Amenities to Housing Values: An Application and Comparison of Spatially-weighted Hedonic Models AgEcon
Cho, Seong-Hoon; Bowker, James Michael; Park, William M..
This study estimates the influence of proximity to water bodies and park amenities on residential housing values in Knox County, Tennessee, using the hedonic price approach. Values for proximity to water bodies and parks are first estimated globally with a standard ordinary least square (OLS) model. A locally weighted regression model is then employed to investigate spatial non-stationarity and generate local estimates for individual sources of each amenity. The local model is able to capture the variability in the quality of water bodies and parks across the county, something a conventional hedonic model using OLS cannot do.
