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.

Impact of an urban growth boundary across the entire house price spectrum: The two-stage quantile spatial regression approach

This study provides evidence for the impact of an urban growth boundary (UGB) on house prices. The study employs a two-stage quantile spatial regression method on a dataset that inventories sales transactions of single-family houses within two miles of either side of the eastern boundary of the primary UGB in King County, Washington. The results show that while the UGB decreases house prices across the entire house price spectrum, the impact is uneven; it is most pronounced for houses in the 5th to 8th decile of prices. These findings should encourage policy makers to adopt sub-housing-market-level policy approaches to address UGB and other urban and regional development policies’ potential impacts on house prices.     

Race and the Production of Extreme Land Abandonment in the American Rust Belt

Extreme land abandonment is one of the most visible expressions of urban decline. Conventional theory emphasizes housing lifecycle processes, municipal fiscal challenges and deindustrialization to explain its prevalence. Empirically however, these factors are not strongly associated with the most extreme instances of land abandonment in the American Rust Belt. Race, by contrast, is strongly associated with these patterns, yet there is little mention of it in conventional theory. This article draws on group threat theory to explain how the construction of Blackness as a threat to white property, power and political influence, has propelled the production of extreme land abandonment. The constructed threat has translated into a sustained suppression of demand and capital for overwhelmingly black neighborhoods. These forces operate both independently and as an accelerant for other abandonment drivers.     

From First Canoe to Statehood: Eight Hundred Years of Economic and Political Change in Hawaii

The Hawaiian archipelago was the last major land area on the planet to be settled, with Polynesians making the long voyage just under a millennium ago. Building on new archaeological and historical research, the lecture provides an overview of the economic and political history of Hawai‘i from the first Polynesian settlements in the thirteen century through U.S. colonisation and statehood. The analysis considers how the political and economic institutions that emerged and evolved in Hawai‘i during its centuries of global isolation changed in response to Hawai‘i's post-1778 integration into a new world of global markets and colonial politics.     

What is the policy improvement of China’s land consolidation? Evidence from completed land consolidation projects in Shaanxi Province

Land consolidation plays an important role in increasing cultivated land, improving cultivated land quality and the ecological environment, and promoting the coordinated development of urban and rural areas. However, under the conditions of three decades of land consolidation being conducted and changing urban–rural human–land relationship, the areas of improvement in the land consolidation policy of China must be studied. This article analyzes the implementation and distribution characteristics of the land consolidation project completed in Shaanxi Province in 2018. Results show that land consolidation projects in Shaanxi are mainly land reclamation projects, cropland consolidation projects, and high-standard cropland consolidation projects. The increased cultivated land is mainly from land reclamation projects and cropland consolidation projects. The land consolidation projects in Aeolian Plateau Area, Loess Plateau Area, and Da Ba Mountain Area are mainly land reclamation projects. The land reclamation projects in Guan Zhong Plain Area and Qing Ling Mountain Area account for a large proportion. The spatial distribution of rural settlement consolidation projects, and rural settlement consolidation and land reclamation projects are mainly located in Guan Zhong Plain Area and distributed in the boundary area of Guan Zhong Plain Area and Loess Plateau Area. According to the characteristics of land consolidation projects and the changes of urban–rural human–land relationship, China should be prudent in or stop advancing land reclamation to increase cultivated land; cropland consolidation and high-standard cropland construction are vital ways to achieve China’s food security; and rural settlement consolidation should be carefully conducted in remote areas under the background of urbanization.

Quantifying and understanding land cover changes by large and small oil palm expansion regimes in the Peruvian Amazon

With rapid increases in global food demand and production, oil palm expansion constitutes a major emerging challenge for forest conservation in Amazonia and other tropical forest regions. This threat is evident in the Peruvian Amazon, where local and national incentives for oil palm cultivation along with growing large-scale investments translate into accelerated oil palm expansion. Environmental sustainability of oil palm cultivation in the Peruvian Amazon is contingent on policy incentives for expansion onto already-cleared lands instead of biodiverse, high carbon primary rainforests. Previous research indicates that while industrial plantations use less land area than local smallholders, companies have a higher tendency to expand into primary rainforests. However, the motivations behind these differing expansion scenarios remain unclear. In this study we combine data from optical and radar satellite sensors with training information, field discussions, and review of public documents to examine the policy incentives and spatial patterns associated with oil palm expansion by smallholders and industries in one of Peru’s most rapidly changing Amazonian landscapes: the Ucayali region of the city of Pucallpa. Based on our satellite-based land cover change analysis, we found that between 2010 and 2016, smallholders utilized 21,070 ha more land area for oil palm than industries but industrial expansion occurred predominantly in old growth forests (70%) in contrast to degraded lands for smallholders (56%). Our analysis of national policies related to oil palm expansion reveal policy loopholes associated with Peru’s “best land use” classification system that allow for standing forests to undergo large-scale agricultural development with little government oversight. We conclude that both sectors will need careful, real-time monitoring and government engagement to reduce old-growth forest loss and develop successful strategies for mitigating future environmental impacts of oil palm expansion.     

A game theoretic approach to optimize multi-stakeholder utilities for land acquisition negotiations with informality

To combat the critical stresses of rising urbanization, the government acquires land from private owners using the power of eminent domain. This land assembly causes negative externalities such as increasing social tension and injustice that may impose a long-term threat to stability and sustainable development. Therefore, there is a need to make the land acquisition process more transparent and just. Considering the unique Indian context where informality has a strong presence, we propose an approach based on game theory that models the bargain through a three-stage Nash equilibrium game. Four agents – the government, the private developer, the landowner, and the free rider – are considered. We provide conditional solutions for the generalizable Case and proceed to model different stakeholder behavior patterns through two utility functional forms – linear and exponential. In the linear case, we find that the free rider obtains half of the revenue of the project, whereas the landowner gains between one-fourth and one-half of the revenue. Thus, we highlight the undeniably crucial role free riders play in land acquisition negotiations. However, closed form solutions cannot be obtained for the exponential form, due to which we use simulations to demonstrate a solution procedure. We conclude by stating that the proposed model can be useful in formulating future land policies in a sustainable and inclusive manner, with optimal utility derivations for all concerned stakeholders. Our model can also be extended to other spatial contexts where informality features heavily in the land market, especially in the Global South.     

Pure rent taxation and allocation of capital in a two-sector open economy: A long-run analysis

In this paper, the long-run incidence of a tax on pure rent is analyzed in an OLG two-sector small open economy, in which one sector produces a capital good and one sector a consumer good. Contrary to what is obtained in a one-sector closed economy, a land rent tax does not necessarily foster nonhumam wealth accumulation and capital formation. The accommodating scheme for the government budget plays a crucial role for the effects of pure rent taxation. A rent tax stimulates nonhuman wealth if distortionary taxes on wealth or on income from nonland inputs are alleviated. The mechanism spurring capital formation is brought into action, instead, only when the rent tax is matched by a fall in capital taxation or, if the capital sector is capital intensive, by an increase in government spending on the capital good.
