The impact of gasoline prices on urban bus ridership

This article examines the gasoline price elasticity of ridership on a city transit system. Multiple regression models are developed to explain variations in ridership due to changes in gasoline prices, bus system size, and other variables. The estimated gasoline price elasticity of bus ridership is. 3, which is very strong statistically. This provides insight into the possible relationship between future federal energy policies which will influence future gasoline prices and urban transportation modal choices.

District heating network ownership and prices: The case of an unregulated natural monopoly

The price of district heating in Sweden is unregulated and differs substantially among different networks. This paper investigates if the price variation can partly be explained by whether the district heating network is privately or municipally owned. The empirical analysis is based on district heating prices, ownership status, and network characteristics for the 2012–2017 period. The results show that prices are higher in privately owned district heating networks than in municipally owned networks, especially in the fixed component of the price. Municipal and private providers' divergent objectives may be part of the explanation for these differences.

Correlates of natural and urban systems

Conclusions We have argued above for a systems view of the city. In particular we have asked that the city be looked at as a particular kind of system: a natural system. By taking this view many of the advances made by systems ecologists in studying more limited ecosystems become available to us.The ecological perspective in urban studies is not new. We feel, though, that previous work has looked at but a few of the important and analogous concepts in natural science. The most critical omission of earlier work has been in the area of stability and complexity. We have tried to define these concepts as finely as is meaningful and to illustrate them and their application to the urban scene.If there is one single conclusion or point upon which we would like to close, it is this: Complexity must be a planning parameter. The intricacy and complexity of urban systems must be preserved and not diminished. It is entirely likely that in the future the maintenance of complexity in the urban ecosystem will be an important planning criterion.     

Neighborhood amenities and their impact on density gradients

The literature is replete with studies of urban population density gradients which utilize a distance variable as their only explanatory variable. This model emphasizes only the trade-off between saving on travel costs and residential space and completely ignores other neighborhood amenities which might be important to consumers' decisions regarding their residential location. While in certain cases this omission might not result in any major distortion, it will distort the estimates in other cases. This study investigates the role played by neighborhood amenities in the determination of population, residential and build area densities in the city of Tel Aviv-Yaffo in Israel. The findings clearly indicate that distance alone fails to explain much of the spatial variation of the above densities and that neighborhood amenities, indeed, play an important role in the determination of densities.

The impact of urban renewal on neighborhood housing prices in Taipei: an application of the difference-in-difference method

This study examined the impact of urban renewal delineation time on housing prices in neighborhoods undergoing urban renewal. More specifically, the study used the difference-in-difference method to assess successful housing transactions in Taipei City from 2008 to 2011. According to the empirical results, before the implementation of urban renewal, the average housing price in the areas that later underwent urban renewal (the treatment group) was lower than that in neighborhoods that did not undergo urban renewal (the control group) by 11,180 NTD. After the urban renewal projects were publicly announced, the price per ping of the control group was increased by 148,800 NTD, while the price per ping of the treatment group was increased by 163,680 NTD. This means that the housing prices per ping in the urban renewal areas were increased by 14,880 NTD more than the housing prices per ping in the areas not affected by urban renewal after the urban renewal projects were publicly announced. This increase, then, indicates the value added after implementation of urban renewal delineation time on houses in the neighborhood. Therefore, research into the impact of urban renewal on housing prices should be concerned not only with the neighborhood factors or time factors of urban renewal delineation. Rather, the two types of factors should be considered at the same time.

Impacts of transit and walking amenities on robust local knowledge economy

As of 2013, knowledge economy has held more than 10% of U.S. employment, generated nearly 20% of national GDP and expect to increase to 25% during the next 20 years. Likewise, Eurostat 2020 aims to increase investment in Knowledge Intensive Business Services (KIBS) to bypass the competitors, Japan and the U.S. As the result, investigating the determinants of robust knowledge economy is a continuing concern between city scholars, planners and leaders. To date, several locational and non-locational factors have been found to be influential. For instance, transit service, walkable street networks and dense neighborhoods that provide walkable access to urban amenities are the location preferences for the creative class. Creative class, in turn, attracts KIBS, and produces innovation which are all contributive to the knowledge-based economic vitality. While such trend is widely supported by the theoretical efforts, there is little empirical evidence on these complex multidimensional relationships and hence this study seeks to investigate both direct and indirect impacts of transit and walking amenities on the robust local knowledge economy. Using Structural Equation Modeling (SEM), we developed a comprehensive model that accounts for KIBS, creative economy and innovation productivity and investigates their locational and non-locational determinants with the particular focus on walking and transit amenities. Our results generally echo the findings of previous studies about the key role of industry clustering, place quality amenities, diversity and tolerance on the three drivers of robust local knowledge economy. We found that among all exogenous variables racial diversity and industry clustering have the most significant direct effect on innovation productivity. We also found that transit service quality and walkability contribute to a robust local knowledge economy through KIBS and creative class, but they have an adverse relationship to the innovation production of the STEM small firms. This might be due to the fact that walkability and transit access increase the property values and, therefore, make them unaffordable for small innovative firms. Our findings on the impacts of walkability and transit access on innovation productivity in vulnerable small firms call for attention to the equity aspects of innovation-supportive urban developments.
