Parking behaviour: Bundled parking and travel behavior in American cities

We investigate the relationship between bundled residential parking and travel behavior, with a particular focus on use of public transportation, and controlling for vehicle ownership. When the cost of parking is bundled into the price of housing, the time and stress of finding parking near home falls. These lower costs may lead households with bundled parking to drive more and use transit less than households without parking, even if both households own vehicles. To date this idea has been difficult to examine empirically. In this article we test this prediction using the public transportation module of the 2013 American Housing Survey. We confirm the association between bundled parking and travel. Households with bundled parking use transit less, spend more on gasoline, and—when they do take transit—are more likely to drive from their homes to the transit stop.     

A study of zoning for energy security in China

As a result of more and more serious energy risks, the study of national energy security zoning is not only the basic requirement of energy risk management but also the new demand of economic development for the energy industry. Firstly, this paper analyzes the basic situation of energy resources and production and consumption of primary. energy from 1996 to 2005 in China. Secondly; this paper founds an Energy Security Index System formed by six indices including the percentage of energy reserves, interlocal dependent degree, energy elasticity coefficient and so on. It subsequently calculates the weight of these indices with the factor analysis rating method Lastly, the paper evaluates and zones the abilities of energy security of 30 provinces in China with the grey chuster method According to their security; the 30 provinces are classified into three different levels： high, medium, and low levels. The regions at low energy security level include Beijing, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi and Hainan. They are mainly littoral and short of primary energy production while mostly dependent on other provinces. Those at medium energy security level include 15 provinces （cities or districts）, such as Liaoning, Tianjin, Hebei, Shandong, Henan, Hunan and so on. These provinces are in the northeast, north, east of and central China. Those at high energy security level contain Shanxi. lnner Mongolia, Heilongjiang, Jilin, Chongqing, Sichuan, Shaanxi. Xinjiang. These provinces are the main primary energy production bases.

Urban encroachment,forest regrowth and land-use institutions: Does zoning matter?

As concern grows regarding urban sprawl and forest and agricultural land preservation, the effectiveness of land-use policies in shaping land-use change warrants further study. We evaluate the impact of county-level zoning laws, the most predominant land use policy in the USA, and land rents on the relative amounts of forest, agricultural, and developed land, while controlling for demographic information and taxation rates. Over the past decades, southern Indiana has experienced forest regrowth on private lands, but this regrowth has declined in recent years with increased conversion of open space for urban residential development. We develop a model of land-use shares in 40 southern Indiana counties based on the net benefits to agriculture, forestland, and urban uses using a maximum likelihood estimation of a Dirichlet distribution. We find agricultural land rent and indicators of land productivity are the most important predictors of the proportion of agriculture and urban uses. Forest use is better explained by shifting regional economic structure and hilly terrain. Counties with a greater proportion of their work force in the service sectors have a greater proportion of land forested. Finally, to some extent zoning may protect agricultural land in the region, although land rents, land characteristics, and population are strong predictors of the ratio of agriculture to urban use.     

Upzoning and value capture: How U.S. local governments use land use regulation power to create and capture value from real estate developments

The public sector can harness its authority to control land uses to secure valuable public benefits from real estate developments. This paper investigates how five major U.S. cities—Boston, Chicago, New York, San Francisco, and Seattle—are using their land use regulation powers to create and capture value for the public benefit. An analysis of the zoning and entitlement processes of the 20 largest real estate development projects in each city reveals that value has been captured from all 100 projects. Furthermore, these cities implicitly differentiated value capture into two distinct components: value creation and value capture. Among the 100 projects, cities created value for 90 projects by allowing greater density and height—a practice often referred to as “upzoning.” Distinguishing such upzoning incidences from traditional land use exaction tools is important because the added value gives local governments greater legitimacy in asking for public benefits. The experience of the five cities further revealed that value capture strategies can be customized to adapt to unique regulatory, political, and cultural contexts. Lastly, despite the fact that the majority of the upzoned projects increased density and height through project-specific negotiations, none of the cities had clear standards or evaluation frameworks for determining: how much value was created, what can be asked for in return, and who should benefit from the value captured. Cross-national scholarship on value capture can be leveraged to address these important questions.     

Duopoly locations and optimal zoning in a small open city

This paper analyzes a duopoly location model with an asymmetric zoning that prohibits firms from locating to a specific interval in a small open linear city. It is shown that the maximum differentiation principle presented in d'Aspremont et al. [Econometrica 47 (1979) 1145] is still valid under area zoning regulation. Moreover, a zoning regulation can be seen as a policy instrument to limit firms' excess profits, and a proper regulation may even reduce the distortion in total transportation costs, therefore enhancing social welfare. Specifically, the optimal zoning is about 29.5 percent of the city with no amenity effect. Finally, all the land rents raised by zoning are eventually confiscated by the absentee landowner.     

Developing grain production policy in terms of multiple cropping systems in China

Multiple cropping is one of the simplest ways to increase grain production, and it has an important role in the food security of China. This paper evaluates the multiple cropping systems of China, and identifies the regional obstacles that limit the use of multiple cropping with the aim to give some implications for developing grain production policy. A time series analysis of remote sensing data coupled with an econometrics model—stochastic frontier analysis (SFA) was used to derive the multiple cropping index (MCI), potential multiple cropping index (PMCI), multiple cropping efficiency (MCE), and potential increment of multiple cropping index (PIMCI) to evaluate the multiple cropping systems. Regional obstacles to the use of multiple cropping were identified by zoning socioeconomic and ecological environmental factors that impact its application. The MCE of China in 2005 was 87.5%, with a gap of 22% between the MCI and the PMCI. The Bohai Rim, the rim of Tianshan Mountain, the Sichuan Basin, and the middle reach of Yangtze River are the main regions that larger PIMCI could be anticipated. The whole country (excluding areas that lacked data) was divided into seven distinct regions in terms of the impact factors and further classified into low-efficiency high-potential regions (LHRs), high-efficiency low-potential regions (HLRs), high-efficiency medium-potential regions (HMRs), and medium-efficiency high-potential regions (MHRs) according to regional multiple cropping performance. Considering about the obstacles and benefits to each region, different strategies should be implemented to different regions for regional grain production increase. Special attention should be paid to the improvement of MCE in north and southwest China with the expectation to increase grain production of China. The results would help implement “The plan to increase grain production capacity by 50 million tons nationwide” launched by the central government of China.     

Developing an appropriate land use methodology to promote spatially just,formal retail areas in developing countries: The case of the City of Cape Town,South Africa

South African scholars have increasingly recognized that the prevailing management system for land use is one not relevant to the current spatial needs of the country's settlements. These include, in particular, the need to create sustainable, spatially just and resilient settlements and to develop land in a manner that promotes efficient urban development. The debate in the South African literature on land use management has, with a few notable exceptions, yet to venture into the specific mechanics of how to fix this system, ways the system can be used to create a spatially just urban form, or its applicability in formal retail areas.This paper addresses these questions within the context of formal retail areas and the zoning category that these are typically found in, namely that of the General Business zone. This paper initially investigates the current exclusionary nature of formal retail areas in the context of South Africa and within Cape Town and how this is linked to the more macro patterns of spatial exclusion within Cape Town. It is argued that within the context of Cape Town there is a need to focus on both commercial, particularly formal retail, as well as residential, areas with regard to the project of creating a more spatially just city. It is subsequently demonstrated, firstly, how zoning scheme provisions could be used as a mechanism to address these patterns of exclusion in formal retail areas, specifically exploring provisions that would encourage inclusion of informal and microenterprises within shopping malls. Secondly, it is demonstrated how provisions can be included that create a safer and more inviting environment for public transport users and poorer employees and consumers, in formal retail areas.The contribution of this paper is to initiate a long overdue conversation regarding the relationship between land use management and social justice within a developing world context, and in formal retail areas, and aims to set out ways in which land use management can be made more relevant; both for South African cities and cities in other developing countries.     

Towards an understanding of proactive upzoning globally and in South Africa

Upzoning typically occurs as a passive process whereby landowners approach the municipality for a change of rights. Proactive upzoning, where a municipality takes the initiative to increase the rights assigned to land in its jurisdiction, can be a powerful tool to encourage development to occur in line with municipal policies. This paper firstly describes the various approaches used to achieve proactive upzoning. The focus then shifts to understanding examples of proactive upzoning in South(ern) Africa, which provide examples of policy transfer of ideas, primarily from the Northern into a Southern context. Four key lessons are identified from this discussion. Firstly, proactive upzoning can affect the poor negatively or positively, depending on the design of the initiative. Secondly, from South African experience, it is clear that there is a danger of proactive upzoning examples from the North being copied almost verbatim and applied in a Southern context, despite the considerable differences in context. Thirdly, there is a need to ensure that initiatives are in line with market dynamics, to avoid ‘wasted’ infrastructure investment. Fourthly, proactive upzoning often just considers zoning schemes’ rights, whereas the land development process can face a slew of regulatory constraints beyond the zoning scheme.
