Riparian buffers, the strips of vegetation along banks of rivers and streams, have been proposed as a key instrument to protect water quality in the United States. Riparian buffers impose a restriction on the use of private property limiting harvest and development, but buffers can also provide for aesthetic and recreational benefits that may accrue to property owners. With data from the Neuse River Basin in North Carolina, this study attempts to provide empirical evidence on the effect of a mandatory buffer rule on the value of riparian properties. Spatial autoregressive hedonic models are estimated within a quasi-experimental framework using the imposition of the buffer rule as the treatment and nonriparian properties as a control group. Results indicate that a riparian property generally commands a high premium. We find no evidence, however, that the mandatory buffer rule has had a significant impact on riparian property values when compared with the control group. 相似文献

Summary This paper examines the ability of the hedonic price method to estimate the premium offered by particular housing attributes or environmental characteristics in an urban setting. Problems of non‐separability in variables within an empirical model, suggest that this methodology is not always suitable for the estimation of specific housing attributes, and an alternative approach to this problem is suggested. 相似文献

Despite the fact that data on farm sales are invariably collected over both time and space, previous papers have allowed for the presence of either temporal or spatial relationships in the data, but not both. Some papers have also inadvertently assumed that although farmland values are influenced by prices realised by nearby sales, these sales need not necessarily be comparable in terms of their attributes. Using data on sales of farmland obtained through public auctions in England and Wales, this paper examines the consequences of explicitly allowing for the presence of a spatio‐temporal lag in the estimation of hedonic models of farmland value. The results indicate that spatio‐temporally lagged values of the dependent and independent variables contribute significant additional explanatory power. Accounting for spatio‐temporal relationships appears moreover to somewhat alter the perceived size and statistical significance of key farmland attributes. 相似文献

Recent ready access to free software and toolbox applications is directly impacting spatial econometric modelling when working with geolocated data. Spatial econometric models are valuable tools for taking into account the possible latent structure of the price determination process and ensuring that the coefficients estimated are unbiased and efficient. However, mechanical applications can potentially bias estimated coefficients if spatial data is pooled over time because the applications consider the spatial dimension alone. Spatial models neglect the fact that data (e.g. real estate) may consist of a collection of spatial data pooled over time, and that time relations generate a unidirectional effect as opposed to the multidirectional effect associated with spatial relations. Through an empirical case study, this paper addresses the possible bias in spatial autoregressive estimated parameters when data consist of spatial layers pooled over time. An empirical study is made using apartment sales in Paris between 1990 and 2001. Estimation results and out-of-sample predictions confirm, at least for this case, the hypothesis that ignoring the time dimension and applying spatial econometric tools generate divergence among the estimated autoregressive coefficients, which can potentially engender other serious problems. 相似文献

This paper examines the spatial dependency exhibited by the error term variance of hedonic modeling based on German housing price data. To this end, it applies the spatial autoregressive conditional heteroscedasticity (SARCH) model previously discussed in housing literature, which allows for the consideration of spatial dependency when modeling the error variance of hedonic pricing. This model represents a spatialized version of the well-known ARCH-model used in time series analysis. Consistent with previous findings, this paper confirms the existence of spatial conditional heteroscedasticity, i.e. dependency in the error variance. However, this spatial dependency is not a global phenomenon, but can be ascribed to spatial concentrations of apartments with a relatively high variance in a small number of the same neighborhoods. The analysis of spatial heteroscedasticity helps to improve the estimation efficiency and prediction accuracy. In addition, spatial differences can be used to account for idiosyncratic risk when conducting mass appraisal. 相似文献

The Effect of Farmland Preservation Programs on Farmland Prices 总被引:5,自引:0,他引:5
Government agencies in urbanizing areas are increasingly utilizing purchase and transfer of development rights programs to preserve farmland and protect local farm economies. This paper tests the effect of development restrictions imposed by permanent easement sales on farmland sales prices, using Maryland data. We correct for selectivity bias due to the voluntary nature of these programs in estimating hedonic sales equations. Although preserved parcels' actual land values are lower, the effect of the restrictions is not statistically significant. These findings may encourage additional participation in preservation programs or justify reductions in the easement prices paid by agencies. 相似文献

This study examines the impact that recommended retail prices, actual market prices and the release of a prominent wine guide have on Australian wine hedonic price estimates, for attributes such as sensory quality, winery reputation and grape region. In general, hedonic price estimates appear to be independent of prices employed. The main identified differences in estimates relate to the size of the producer and some regional impacts. For market prices only, increases in producer size are estimated to reduce prices. This implies the existence of supply chain quantity discounting price practices. The impact of an authoritative wine guide appears to have a negligible influence on prices in Australia. In the absence of market transaction prices, the common practice of employing recommended prices for hedonic wine price estimation is defendable. 相似文献

Controlling for spatial effects in micro‐level studies of consumer and producer behaviour necessitates a range of analytical modifications. These range from modest changes in data collection and the definition of variables to dramatic changes in the modelling of consumer and producer decision‐making. This paper discusses conceptual, empirical and data issues involved in modelling the spatial aspects of economic behaviour in data‐rich environments. Attention is given to established and emerging agricultural economic applications of spatial data and spatial econometric methods at the micro‐scale. Recent applications of individual and household data are featured, including models of land‐use change at the urban–rural interface, agricultural land values, and technological change and technology adoption. 相似文献

As the Global Financial Crisis has shown, housing market bubbles can have widespread economic consequences. Housing submarkets matter but economic theory is divided on how the spread of prices between low- and high-value segments varies with the market cycle and few studies examine the issue. This paper addresses that gap, using a detailed data-set of over one million property listings for Ireland from 2006 to 2012. Using hedonic methods, controlling for time and attributes, standardised prices for over 1100 sales zones and 300 lettings zones are calculated and then compared for mid-2007 and mid-2012. There are four key findings. Although, firstly, the spread of prices across different property sizes increased significantly between bubble and crash, the spread of rents, secondly, fell. There was, thirdly, at most a small fall in the spread of both prices and rents across space. Lastly, in both periods, the spread of rents was constrained relative to that of prices, particularly in the upper tail. The evidence from Ireland indicates that the relative gap between low- and high-value segments grew in the crash. This is important for macro-prudential policy. There are also local implications, as Ireland deals with legacy supply issues, predominantly in low-value segments. 相似文献

The aim of the present study is to test empirically the Environmental Kuznets Curve (EKC) hypothesis for 42 Romanian counties over the 2000-2014 period. Specifically, we investigate the existence of an inverted U-shaped curve relationship between residential built-up land and economic development in a low-income EU country undergoing rapid and profound transition. We do so by making innovative use of spatial panel econometric techniques. Contrary to our expectations, the results indicate an inverted EKC, implying that higher levels of residential built-up area occur for higher levels of wealth. Moreover, we find that the built-up land in Romania mainly reflects processes of urban expansion, such as sprawl or suburbanization, that may have harmful environmental and social consequences. Spatial spill-overs in terms of built-up land arise and spread, albeit to a limited extent, to neighbouring locations. These findings are of potential significance for policy makers, because they highlight the need for coordination among neighbours. Furthermore, strengthening the institutional framework and local tax management, and planning urban regeneration better could curb and even reverse the extensive built-up land expansion and real estate speculation. 相似文献

Under certain circumstances, land titling, property regime changes, and land-use conversions yield substantial profits. Yet few people possess the wealth, knowledge, and networks to benefit from these procedures. In the Yucatán Peninsula, a region recently targeted as a prominent investment location by the Mexican national government (mainly with the “Tren Maya” megaproject) and the private capital, forestlands collectively owned as ejidos by Mayan peasants are on the trend to complete privatization. Against the arguments of neo-institutional economists that in the 1990s promoted legal reforms and justified land-titling programmes worldwide to make available credit for uncapitalized peasants, individual land titling of commonly held lands in Mexico increased the overall economic value of the land, but not the investment in economic activities related to farmland and indigenous communities. Instead, those policies enabled land grabbing, dispossession, and urbanization. In this article, I describe recent private-led initiatives of ejido land titling that have redefined agricultural land's uses, meanings, and values for capitalist accumulation. In doing so, I explain how and why Mayan ejidatarios have been excluded from the monetary benefits of land titling, a top-bottom dispossession process only accomplished through shadow procedures and former privatization of ejidos' common lands. 相似文献
