Spatial dependency and technical efficiency: an application of a Bayesian stochastic frontier model to irrigated and rainfed rice farmers in Bohol,Philippines

We investigated the role of spatial dependency in the technical efficiency estimates of rice farmers using panel data from the Central Visayan island of Bohol in the Philippines. Household‐level data were collected from irrigated and rainfed agro‐ecosystems. In each ecosystem, the geographical information on residential and farm‐plot neighborhood structures was recorded to compare household‐level spatial dependency among four types of neighborhoods. A Bayesian stochastic frontier approach that integrates spatial dependency was used to address the effects of neighborhood structures on farmers’ performance. Incorporating the spatial dimension into the neighborhood structures allowed for identification of the relationships between spatial dependency and technical efficiency through comparison with nonspatial models. The neighborhood structure at the residence and plot levels were defined with a spatial weight matrix where cut‐off distances ranged from 100 to 1,000 m. We found that spatial dependency exists at the residential and plot levels and is stronger for irrigated farms than rainfed farms. We also found that technical inefficiency levels decrease as spatial effects are more taken into account. Because the spatial effects increase with a shorter network distance, the decreasing technical inefficiency implies that the unobserved inefficiencies can be explained better by considering small networks of relatively close farmers over large networks of distant farmers.     

Does new urbanist neighborhood design affect neighborhood turnover?

This paper explores the extent to which new urbanist principles (e.g., compactness, mixed use, street connectivity, and open space) influenced neighborhood residential turnover in Austin, Texas, from 2009 to 2011, with a focus on micro-scale-level neighborhoods. The results of this study indicate that new urbanism principles play unique roles in turnover, most of which appear to be positive in increasing turnover, except the sidewalk and proximity to a lake. In summary, residents currently tend to reside longer in a neighborhood with typical suburban neighborhood designs, not new urbanist. Among the design principles of interest in this study, proximity to a lake proves to be the most powerful predictor, followed by distance to the CBD and dwelling density. As natural features such as lakes or hills are given conditions that are less likely to be altered by humans, we conclude that turnover tends to be sensitive to “compactness.” Thus, planners are urged to carefully consider the issue of “compactness” to successfully create stable neighborhoods.

Neighborhood socioeconomics,food environment and land use determinants of public health: Isolating the relative importance for essential policy insights

Recent literature has advocated the connection between land use policies with public health promotion. In this regard, examining the land use determinants of public health and isolating the relative importance with other influential factors should provide essential policy insights. However, very limited efforts have been made in this aspect, particularly for the developing countries. Using a case of Wuhan (China), this paper attempts to capture the land use determinants of obesity prevalence among middle-aged adults and to compare the relative importance with neighborhood socioeconomics and food environment. A conceptual framework is first proposed to guide the analysis within a land use policy context. Data are then collected during the China’s National Physical Fitness Survey in 2010 and multivariate linear regression is applied to analyze the district level determinants. Results show that neighborhood socioeconomics, food environment and land use all have significant effects on obesity prevalence among the middle-aged adults. The men obesity is associated with the occupation, education and housing, while women obesity is correlated with income and housing. Women obesity associates with healthy food environment, while men obesity correlates with unhealthy food environment. Open public space is negative to women obesity, and institutional land is negative to men obesity. Greater walkability and street connectivity associate with lower obesity risk for both genders. The variance decomposition demonstrates that food environment is the most important determinant of men obesity, while land use is the most essential determinant of women obesity. For the obesity prevalence among total population, neighborhood socioeconomics are key determinants. Based on our analysis, we finally provide some insights for land use policies that aim at addressing the obesity issue in developing countries.     

What is the value of built heritage conservation? Assessing spillover effects of conserving historic sites in Singapore

Quantifying the economic benefits of built heritage facilitates the formulation and assessment of conservation policies and programs. There is however a lack of empirical research about the economic value of built heritage in Asian cities. This lack is problematic, given the rapid pace of demolition and redevelopment of historic landscapes in Asian cities. This study seeks to reduce the current gap in built heritage research by examining whether real estate premiums are generated by the designation of buildings as ‘conserved’ in Singapore, a city-state in South East Asia. Using 20 years of housing transaction data, and controlling for building, neighborhood and year fixed effects, we found that conservation designation had a positive impact on average sale prices per square meter of built area that was largest at residential locations between 800 m to 1.6 km from the conserved site. Findings also suggest that lower-cost public housing resale units gained a substantially smaller premium compared to private housing units. While our findings suggest an economic justification for building conservation programs in Asian cities, they also raise questions about such programs potential impact on neighborhood gentrification, and the need for appropriate taxation policies to ensure horizontal equity between property owners.
